Latest / Scientific Health: Education and Human Performance / Should we call them "Superfoods"... or are they just foods
Transcript
- 0:00Well, thanks for joining today.
- 0:01We're going to talk a little bit about some stuff based off of a few questions
- 0:06that got brought up with a conversation I was having the other day with some students
- 0:10regarding free radicals and the need for antioxidants in the diets
- 0:14based off of the things that we eat and the things that we do on our daily basis.
- 0:18And some of them were asking my opinions about all of these supposed superfoods
- 0:22and superfood supplements that are out there in the market
- 0:26because they were talking about what they heard is that
- 0:28we need all of these various types of superfoods and various types of supplements
- 0:33to help control inflammation, help improve their health, help get rid of
- 0:38I think they called it gut bloat in terms of their overall health.
- 0:43And so there's a few things we have to remember, a few things that we have to
- 0:46when we look at stuff that goes in there is it goes back to what we've been
- 0:49talking about for a long period of time.
- 0:52Does it really matter what we eat?
- 0:54And because we don't focus on a lot of the nutritional aspects
- 0:59as relates to what we eat because of the guise of diet
- 1:03based off of calories and not based off of nutrients, we get a misunderstanding
- 1:07of some of the science and principles that are out there that have led to all of these
- 1:11supposed superfoods and all of these different types of bad diets.
- 1:17And a lot of what these have come out
- 1:22in terms of the market is that they make these kind of claims.
- 1:25And what I remember is that if I'm going to make astronomical claims,
- 1:30I need to have astronomical support.
- 1:33And so one of the things that we have to fall back on is the fact that
- 1:37a lot of the claims of benefits might not be true.
- 1:56So in order to take a look at what we're talking about,
- 2:02we talk about superfoods and antioxidants.
- 2:04The first question we have to kind of address is what are superfoods
- 2:10and what are antioxidants and should I be eating antioxidants?
- 2:16Well, here's the kind of kicker.
- 2:18Here's the thing about a lot of these things.
- 2:21Superfoods is a marketing gimmick.
- 2:24It's a marketing ploy.
- 2:25It's a statement about marketability
- 2:29based off of supposed benefit that you might get from specific types of foods,
- 2:34based off of some of the chemicals that might be present within the foods.
- 2:39And most of the chemicals that are being reported as being the,
- 2:43quote unquote, active ingredient within these superfoods
- 2:48are predominantly antioxidants.
- 2:53And so just doing a quick Internet search,
- 2:56you get what are the 20 best superfoods?
- 2:59What are the 50 best superfoods?
- 3:01What are the 80 best superfoods?
- 3:02Here are the 10 best superfoods.
- 3:05What does superfoods actually do for you?
- 3:08And it comes down to the fact that I think we're misusing the word super here.
- 3:13When we say superfood,
- 3:14what we're basically indicating is that there's some food out there
- 3:17that has some sort of special nutrient benefit to it.
- 3:20And if that's the case, then we would have the scientific evidence
- 3:23to say that this is the food
- 3:26that will provide the greatest nutritional benefit for you.
- 3:29And that just doesn't seem to be the case.
- 3:31What the marketing play of superfood is meant to imply
- 3:35is that this kind of food, this food additive,
- 3:39this food preservative, this supplement
- 3:43is somehow having some sort of excessive nutrient value
- 3:47relative to other things that you might eat.
- 3:51And what they're typically doing is that they're typically giving us foods
- 3:55that somehow match an antioxidant food.
- 3:58The food sources that we have that are being labeled as superfoods
- 4:03are food sources that have chemicals
- 4:07that have been indicated as being an antioxidant
- 4:10or are involved with metabolic processes within the cells of the body
- 4:15that help control for radicals.
- 4:17But the problem is, is that the way in which most of these
- 4:20quote unquote superfoods are sold
- 4:22is that they're sold as some sort of supplement, some sort of powder.
- 4:25Drink this, and once again, I'm not going to name any company here
- 4:29because I don't want to give anybody free airtime.
- 4:32And a lot of the propoted benefits that come about
- 4:36from some of the supplement companies is sketchy at best.
- 4:41If I eat the food source as the food source,
- 4:44I get greater nutritional value from it than when I grind up
- 4:47that food source and turn it into a dry powder
- 4:50and then mix it into a liquid and drink it.
- 4:52It's not always the case, but it is the predominant trend,
- 4:56particularly with where we're discussing these quote unquote superfoods
- 5:01coming from, is that once I take the foods out of the quote unquote
- 5:06natural environment, out of the actual food itself
- 5:10and turn it into some sort of supplemental thing, some sort of powder.
- 5:16The benefit that I could get from that food drops.
- 5:21There are some of this labeled superfoods where this isn't the case.
- 5:25There are some things that we turn into teas that do have
- 5:30some of the antioxidant properties that we see within superfoods
- 5:34that we don't get if we were to chew on the leaves
- 5:38and not steep the leaves in terms of brewing tea.
- 5:42Same thing with the extracts that we get from coffee
- 5:47and from the coffee nut.
- 5:50Where if I was to chew on the coffee bean,
- 5:55I would not get the same properties that I get from the extracted oils
- 5:59and the extracted esters that come out of brewing of coffee.
- 6:04However, for most of the other things that we label as being superfoods,
- 6:07that's not the case.
- 6:08Most of the nutritional value that we see with these things
- 6:12that are labeled as quote unquote superfoods comes from them
- 6:15being in their food source, not in their product.
- 6:19They're in their source, not in their powder source.
- 6:22Now, the other thing we have to have here is a big huge caveat
- 6:25on this superfood label, particularly when it comes to the claims
- 6:28of purported benefits, is that we have very limited empirical evidence
- 6:33to support many of the claims that are out there.
- 6:35If you look at individual chemical compounds that might be found within the foods,
- 6:39the chemical compounds based off of a actual specific dose recommendation,
- 6:44we will see some actual chemical physiological responses to them,
- 6:48but we don't know those dose variables when we talk about in terms of
- 6:52either a supplement or as the food source itself.
- 6:56I've yet to see any empirical study looking at the claimed superfoods.
- 7:01There are a number of books out there, but the books that are out there
- 7:05are not peer reviewed in terms of scientific methodology
- 7:10and analysis of the findings to actually ensure that the claims
- 7:15being put out are the claims that are true.
- 7:17We can stipulate that superfood is nothing more than a marketing ploy
- 7:21in order to try to get us to purchase specific things
- 7:24because somehow by eating this thing or drinking this powder,
- 7:29we're somehow going to be healthy.
- 7:31I'll have a little bit more comment on that near the end of the talk here.
- 7:35But what about supplements and what about eating things that are going to provide
- 7:38my body with extra amounts of antioxidants?
- 7:42And this is where we have a catch-22, and I'll explain why
- 7:45as we go through the presentation here.
- 7:46The actual empirical science tells us is that when I am physically active,
- 7:51whether that's doing endurance training or doing any type of strength training,
- 7:58so doing what people call cardio or doing running or jogging or lifting weights
- 8:04in terms of the resistance training or lifting weights and running
- 8:09or doing any of the type of cardio for the endurance training,
- 8:12if I'm physically active and if I'm eating a variety of different types of foods
- 8:19where I'm going to be able to not just be eating a single type of food
- 8:24or single type of food source, but be eating multiple types of food sources,
- 8:28utilizing various types of exercise regimens and physical activity regimens.
- 8:33So if I'm able to stay relatively physically active,
- 8:37eat a variety of different types of foods, and do a few other things,
- 8:41like avoiding foods that are high in trans fats.
- 8:46Once again, we don't want to eat more than maybe a gram to two grams
- 8:49of trans fats in a total day.
- 8:51Avoiding things like smoking, avoiding heavy amounts of drinking.
- 8:55If I can avoid trans fats, if I can avoid smoking, if I can avoid heavy drinking,
- 9:00then I don't need to eat additional foods
- 9:03indicated as having large amounts of antioxidants.
- 9:06And I definitely don't need the supplements that are supposedly
- 9:10going to contain large amounts of antioxidants.
- 9:14One of the problems with taking the supplements with antioxidants
- 9:17is that we actually don't know the true amount of bioavailable chemicals
- 9:21that are known to be antioxidants within the supplements we're taking.
- 9:25We may know how much is there, but we don't necessarily know
- 9:28how much will pass through the liver and allow for circulation throughout the body
- 9:32to provide antioxidant properties to the body.
- 9:35Antioxidant properties within the chemical reactions
- 9:38necessary to control for radicals for the rest of the body.
- 9:41There's different types of chemical reactions that take place
- 9:43in terms of chemical reactions that allow for things to be active within the body,
- 9:48what we refer to as being bioactive.
- 9:51But we also don't know how much of the stuff that we're taking
- 9:54in the supplements will be absorbed, which is sometimes referred to as bioavailability.
- 10:00And so as long as I'm avoiding those factors,
- 10:03the trans fats to a high amount, trying to avoid smoking,
- 10:08and it really doesn't matter what kind of smoking, just avoiding the smoking,
- 10:13and avoiding high amounts of alcohol consumption,
- 10:17staying relatively physically active,
- 10:19then I don't need to over consume the antioxidants
- 10:21and I definitely don't need to worry about the supplements that contain antioxidants.
- 10:26And why is that?
- 10:27Well, it goes into how the, how the free radicals are going to form within the body.
- 10:31And what antioxidants happen to be, because remember,
- 10:34all of these quote unquote superfoods are going to basically be foods
- 10:38that contain antioxidants within them.
- 10:41And the antioxidant supplements, the antioxidant foods that we're going to be consuming
- 10:45are meant to be consumed in such a way as to help control free radicals.
- 10:50And it falls back onto the chemistry part of the science that the body uses
- 10:55in order to maintain optimal states, what is sometimes referred to as homeostasis.
- 11:00And the type of reactions that most often are going to be involved within the body
- 11:04are sometimes referred to as redox reactions, scientifically,
- 11:08reduction and oxidation reactions.
- 11:10And what the reduction oxidation reactions are doing is that they are reactions that are
- 11:15happening between molecules, between atoms, where electrons are bonding together
- 11:20and splitting apart within the molecules.
- 11:23In this, sometimes the molecules will gain and sometimes molecules will lose their strength.
- 11:29Sometimes molecules will lose electrons.
- 11:31In the gaining and losing of electrons, we undergo reduction and oxidation.
- 11:36And so if I'm in a reduced state, that means that I have gained electrons.
- 11:42In the case of how the body works, we usually look at it in terms of hydrogen ions.
- 11:46In the oxidized state, I have lost electrons within the reactions.
- 11:52And so a lot of the metabolic processes that the body is going to use
- 11:56will undergo this reduction and oxidation reactions where we'll have molecules in a reduced state
- 12:01and molecules in an oxidized state.
- 12:03And sometimes we get reactions that occur too quickly for full reduction and full oxidation to take place.
- 12:11And when we get that, reactions occurring a little too quickly to get full reduction and full oxidation,
- 12:16that's where we get free radical formations.
- 12:19And the free radical formations occur when we get an unpaired electron within the atoms of the molecule.
- 12:26And the way which electrons work, and I know this is going to get a little beyond what most people
- 12:32want to hear about in terms of the science here, is the way in which electrons work is that they
- 12:38spin around the nucleus of the atom.
- 12:40And as they spin around the nucleus of the atom, they move in a kind of a piston-like action
- 12:45within their, what we call the orbit, the spinning around of the nucleus of the atom.
- 12:52And they're paired up.
- 12:54So if one is spinning in an upwards direction,
- 12:57its paired electron within its orbit is spinning in the downward direction.
- 13:01And what this does is this keeps everything stable within the molecule.
- 13:05But when we have these reactions occur too quickly,
- 13:07what ends up happening is that the unpaired electron is out of sync with how it should be
- 13:12orbiting around the nucleus.
- 13:13And what it's going to do is it's then going to try to sync with some other atom.
- 13:18It's going to seek out other electrons that it could somehow pair with in order to get
- 13:25its piston action to balance itself out.
- 13:27Very similar to how the pistons in your engine is going to sync so that we have a balance within
- 13:34the engine of our car in terms of the internal combustion engine.
- 13:38And so these molecules, these free radicals, are going to come about from reactive reactions,
- 13:44reactions of reduction in oxidation that occur,
- 13:47where we're looking at three principal atoms that will generate our free radicals,
- 13:53our reactive species.
- 13:54Sometimes referred to as reactive oxidative species.
- 13:57And these are going to be our reactive oxygen species, our OS, our reactive nitrogen species,
- 14:04our NS, and our reactive sulfur species, our SS.
- 14:11Now for simplistic purposes, we usually will simplify this down to reactive oxidative species,
- 14:17ROS, or reactive oxygen species, ROS.
- 14:21Now we have to remember is that the free radicals themselves,
- 14:24even though we talk about it as being oxidative species,
- 14:28is not necessarily an indication that is oxygen,
- 14:32nor is it going to come from the oxygen reactions within the cell.
- 14:37And so these molecules, because they're unstable,
- 14:40because they're missing the electron to pair up within the piston action that's taking place,
- 14:46they start to wobble.
- 14:48And it's that wobbling that occurs that leads to an oxidized state for the free radical.
- 14:56And what it's attempting to do is it wants to go out and wants to bond onto something
- 15:01so that it gets out of this oxidized state.
- 15:05So it's able to get reduced or it's able to get stabilized.
- 15:08And so that wanting to bond onto other things,
- 15:13the constant interaction with other molecules within the body triggers metabolic stresses.
- 15:18It triggers metabolic stresses as what that molecule is attempting to do is attempting
- 15:23to pair with every other molecule it comes in contact with,
- 15:27regardless of how stable that molecule happens to be.
- 15:30And there's various types of free radicals that can come about
- 15:34that will generate different types of metabolic stresses based off of where we see the radicals
- 15:40within the body, whether they're intracellular within the cells themselves,
- 15:44or if they're interstitial between the cell tissues,
- 15:48or if they're in circulation within the fluids of the body, particularly within the blood,
- 15:54leading to different types of damages that can take place.
- 15:58And so what this is going to lead to is the body not wanting to be out of bounds,
- 16:02and the body is going to do something in order to help keep the body in balance.
- 16:07And what it's going to do is it's going to generate molecules
- 16:10that are meant to temporarily stabilize this radicalized molecule,
- 16:15this molecule that is in that oxidized state trying to find some sort of electron
- 16:21to stabilize that wobble that it happens to have.
- 16:25And it does this through the generation of the antioxidant.
- 16:29And what the antioxidant is, is it's a stable molecule that has an extra electron within
- 16:35that electron's orbit that it can temporarily give to the free radical.
- 16:41So what it does is it kind of binds to the free radical in such a way so that it becomes stable,
- 16:48and it becomes stable long enough either to be metabolized into something else,
- 16:52or be excreted from the body, either through respiration, breathing out,
- 16:58or through sweat, or through urine, or through excretion of bile into the intestines.
- 17:03And so what the antioxidant is going to do is it's going to temporarily bind onto
- 17:08this free radical, and it's going to temporarily bind onto the free radical
- 17:11so that we're able to reduce the metabolic stress that's taking place.
- 17:17And that's great if we're able to keep our body in balance.
- 17:20And we're able to keep everything in balance because we're going to have distinct things
- 17:23that are going to be able to produce antioxidants for us,
- 17:28which means we don't have to be constantly eating them.
- 17:31So within the body, we're going to have a whole bunch of things that are enzymatic
- 17:34and a whole bunch of things that are non-enzymatic.
- 17:38We have enzymes and coenzymes.
- 17:39One of the ones that everybody hears about is something known as CoQ,
- 17:44and Co stands for coenzyme. And so CoQ is one of those coenzymes that will act as an antioxidant.
- 17:53And that is predominantly found within the cells as a means to control radical formation
- 18:00in the energy pathways, in the pathways that are meant to produce ATP for the body.
- 18:06But we'll also see it within the cell structure,
- 18:09the cells of the liver and cells of the kidneys that are attempting to quote unquote detoxify.
- 18:16But then we also have other things that are non-enzyme, non-coenzyme things such as flavonoids,
- 18:21metal binding proteins, an amino acid known as gluthinine.
- 18:27Then we have some other things like uric acid, melatonin, bilirubin, polyamines.
- 18:33And then we have the
- 18:35coenzymatic factors such as vitamin D, vitamin A, vitamin E, and a few of the vitamin Bs.
- 18:47All of these are going to be antioxidants that the body has,
- 18:51that the body is either able to generate from other metabolites or produce itself.
- 18:58And so what we have to remember here is that we're attempting to control the radicals with
- 19:02those antioxidants. Now here's the problem. If I have too many antioxidants or if I have too many
- 19:07free radicals, we're indicating here if I have enough too many free radicals, but the antioxidant
- 19:14itself can act as a free radical because once again it has that unpaired electron,
- 19:18something we'll talk about here in a few minutes.
- 19:22If I have too many free radicals, I'm going to have to use a few different
- 19:25in a few minutes. If I have too many of those free radicals, I enter a state of oxidative stress.
- 19:33It's this state of oxidative stress that we're trying to control.
- 19:37Oxidative stress is one of the key factors when it comes into quote unquote aging and is a key
- 19:46trigger in a lot of the non-communicable inflammatory issues, stress response disease setup,
- 19:52where I am sick, but quotes around the sick, where I am sick, but I'm not contagious. So
- 20:00non-communicable disease typically comes about from oxidative stress. Now the other thing comes
- 20:06about from oxidative stress is what we typically think about when we think about quote unquote aging.
- 20:13So when I am quote aging, end quote, I am building up oxidative stress. One of the ways in which we
- 20:21can see how much oxidative stress is occurring is to look at grain of hairs, the loss of the melanin
- 20:30pigmentation within the hair follicle due to accumulation of super oxides. Other things to
- 20:37look at in terms of oxidative stress as it relates to non-communicable diseases are a lot of the wear
- 20:44and tear breakdown that we might see within the body as we get quote unquote older. And so what
- 20:50are some of these things that are going to contribute to oxidative stress? The accumulation
- 20:55of super oxide formations. Super oxide formations are a lot of the peroxides that can form within
- 21:05chemical reactions. Low density lipoprotein oxidized molecules. This is where we have to worry about
- 21:13high amounts of LDL levels within our cholesterol molecule measures within our cardiovascular
- 21:20functions leading to atyloscorosis, quote unquote hardening of the arteries. And that is because the
- 21:29LDL oxidized molecule, the oxidized LDL molecules is a free radical and can lead to oxidative stress
- 21:39within the cardiovascular system. A whole host of lipid peroxides as well as nitrous
- 21:49theels. And nitrous theels are going to come about from excessive amounts of protein degradation,
- 21:56breakdown of proteins and reactions with nitrates and amino acids. Now it can't just be just because
- 22:03of accumulations. We have a whole bunch of antioxidants that are naturally occurring within
- 22:08the body, both enzymatic as well as non-enzymatic. If I start losing my antioxidant molecules
- 22:15because I'm in a constant state of stress or I'm in a constant state of oxidative stress,
- 22:20or if I am constantly being sick, I'll see a loss of my antioxidant molecules from within my body.
- 22:27And so a reduction of things like cytochrome C, coenzyme Q within the liver NADPH or NADBH2,
- 22:35superoxide demutase, luthionine peroxidase. Those two are very important enzymes within
- 22:43the antioxidant reactions. Reduction of specific antioxidant vitamins such as vitamin E,
- 22:51vitamin C, vitamin D, vitamin A, and then a few of the vitamin Bs.
- 22:56A loss of luthionine from our diet can also lead to oxidative stress or a loss of the ability to
- 23:04produce luthionine can lead to excessive oxidative stress.
- 23:13And so when we look at this, what is the outcome of either having too many radicals or
- 23:21not enough antioxidants? When we're in a state of oxidative stress, we have an increased risk
- 23:27for developing things like metabolic diseases, cancers, and cardiovascular disease.
- 23:36When we talk about metabolic diseases, one of the ones that everybody knows about is type 2 diabetes,
- 23:43which everybody somehow links to the type 2 diabetes syndrome.
- 23:48Cardiovascular disease is predominantly going to be due to atherosclerotic changes,
- 23:55quote unquote stiffening of the arteries, which leads to hypertension, high blood pressure.
- 24:02Oxygen is a very important enzyme in the blood, and it's a very important enzyme in the blood.
- 24:07So, we're going to be looking at the type 2 diabetes syndrome,
- 24:12which leads to a high blood pressure. Oxidative stress can actually cause changes in gene
- 24:22expression, and particularly expression of distinct oncogenes. And oncogenes are the genes that
- 24:29are going to trigger cancer growth within the individual.
- 24:35And so what are some of the various types of oxidative stress diseases that we might have?
- 24:39Things like retinol degeneration, macular degeneration, possible cataract formations within the eye.
- 24:51Early, quote unquote aging, excessive inflammation, susceptibility to infection,
- 25:00early wrinkling,
- 25:01dermatitis within the skin, expression of things like eczema, risks for skin cancers,
- 25:17expression of possible autoimmune diseases, such as rheumatoid arthritis or lupus.
- 25:25Within the bones and within the joints of the body, development of osteoarthritis,
- 25:31what people usually refer to as simply arthritis.
- 25:37Cardiovascular, we can have hypertension. We can have what's referred to as cardiomyopathy taking place.
- 25:43That is where the muscles of the heart are going to be affected.
- 25:49And then we have cardiomyopathy taking place. That is where the muscles of the heart will grow larger than what the muscles of the heart should grow.
- 25:59So as to overcome the excessive blood pressure that the heart has to pump against.
- 26:05The high blood pressure and the cardiomyopathy can lead to heart failure.
- 26:10We can get cirrhosis of the liver. We can get renal nephritis, inflammation within the nephrons of the kidney.
- 26:21We can get chronic kidney diseases.
- 26:25What is very interesting is that a lot of the neurodegenerative diseases that we wanted to attribute to specific things
- 26:32seem to come about due to excessive oxidative stress, particularly dementia,
- 26:37Alzheimer's disease, increased risks for people who have bipolar issues, expression of bipolar issues,
- 26:47people who are susceptible to migraines.
- 26:51Excessive oxidative stress can trigger migraines.
- 26:55One of the ways in which migraines can come about is associated with fluctuations of
- 27:04estrogens within the body and that has to deal with estrogen's ability to regulate antioxidants and control oxidative stress.
- 27:18And so there is some susceptibility, particularly for females, within menstrual cycles when we have estrogen spikes and estrogenators
- 27:29high amounts of estrogen and low amounts of estrogen to have migraine issues, particularly within their menstrual cycles.
- 27:40And so a lot of these issues with oxidative stress and the need to have antioxidants has led to recommendations by registered dieticians
- 27:50and by many of the dietician associations that we need to eat foods with antioxidants, which is true.
- 28:00We do need to eat foods with antioxidants.
- 28:04And this is where we get the adage that we should be eating the rainbow.
- 28:09And when we say eat the rainbow, we want to make sure is that we're eating foods that have a variety of colors within it.
- 28:14And that's because the colors that we see, particularly within our fruits and vegetables, is going to provide the base materials necessary to build the antioxidants that we need within the body.
- 28:29Especially if we have any of the warning signs that we would need additional antioxidants, such as being sedentary, eating foods with high amounts of trans fats,
- 28:40eating foods with high amounts of saturated fats, smoking, drinking.
- 28:46But what that doesn't mean is that we have to have more antioxidants within the diet than what we should have within the diet.
- 28:55And so what are the antioxidants going to do to help with oxidative stress?
- 28:59They're going to help to temporarily bind on to those free radicals.
- 29:04And so what are the ones we're going to get from our diet that are going to help us to get rid of the antioxidants?
- 29:09The ones that are going to help us get rid of the antioxidants that we're going to get from our diet that are beneficial to us?
- 29:15Things like vitamin C, coenzyme Q, beta carotene and vitamin A, vitamin D, our flavonoids, our retinols, zinc.
- 29:28Are all antioxidant molecules or parts of antioxidant molecules that we can get from our diet.
- 29:34But once again, that doesn't mean that we have to over consume them.
- 29:37We need to consume them, but we don't need to over consume them.
- 29:42And the indication that some of these quote unquote superfoods have higher amounts of these
- 29:50molecules and minerals within them relative to other foods is not an indication that it's going to provide any additional benefit
- 29:59than we might get simply from eating the rainbow, eating foods that have multiple colors.
- 30:04Not just eating beige.
- 30:07And by eating beige, we're simply saying, don't just eat one type of food.
- 30:17But the thing we have to remember is that most of the antioxidants that we're going to be utilizing in our body come from the body.
- 30:25And we're going to try to keep everything in balance.
- 30:27This means that if we start to over consume the antioxidants, the body is going to slow down the rate at which we're producing those antioxidants.
- 30:39We're going to try to keep everything in balance.
- 30:41The body wants to make sure that we don't have too much.
- 30:43We don't have too little.
- 30:45We want to be just right.
- 30:47I usually talk about this in terms of making sure that we are baby bear.
- 30:52Not too hot, not too cold.
- 30:54Just right.
- 30:55Not too soft, not too hard.
- 30:56Just right.
- 30:58A lot of people mistakenly think about this as being in the Goldilocks zone, but it's not really about being in Goldilocks zone.
- 31:04It's about being in the baby bear zone because the body wants to be baby bear.
- 31:08It doesn't want to be too much.
- 31:10It doesn't want to be too little.
- 31:11It wants to be just right.
- 31:18And so when we have normal consumption of antioxidants, when we're eating a colorful diet,
- 31:24when we are physically active, we're able to produce the antioxidants that the body needs.
- 31:32The more active we are, the more antioxidants the mitochondria within the cells will produce to help us out with any type of free radicals that might come from our energy metabolism.
- 31:43If we are eating all of the stuff that we should be eating, meaning that we're not eating beige,
- 31:49the liver is getting all of the nutrients the liver needs to get in order to make sure it's able to do its detoxification reactions
- 31:58and it's able to do its reactions to eliminate any of the super oxides and free radicals that might come about from
- 32:05the detoxification reactions so that we're able to stay relatively healthy.
- 32:15And so remember, we want to keep everything in balance.
- 32:17Everything needs to be kept in balance so that we don't go too far to one side or too far to the other side.
- 32:25And the amount that we eat for these antioxidants is going to be the amount that we eat for the rest of our body.
- 32:34The amount we eat for these antioxidants, the amount we eat based off of our need, is very, very small.
- 32:43We're talking milligrams and micrograms for most of them.
- 32:47And if we over consume them, it can lead to issues.
- 33:05And the issues that can come about include things like oxidative stress.
- 33:08There was a story that came out 20, 30 years ago now, almost 40 years ago now,
- 33:18about consuming vitamin C as a means to prevent cancer.
- 33:22And that's because if we can reduce oxidative stress, we can reduce any of the genetic
- 33:31issues that can come about from oxidative stress on the genes.
- 33:34And vitamin C is a very good antioxidant at controlling oxidative stress on DNA.
- 33:43But what the research showed is that if we actually wash cells with, if we give these cells too much of the antioxidant,
- 33:51it actually causes oxidative stress that the vitamin C was supposed to counterbalance.
- 33:56And so it actually doesn't reduce the cancer risks.
- 34:04There was, and once again, this statement came out almost 50 years ago now,
- 34:09about consuming vitamin C in order to offset symptoms of the cold, the common cold.
- 34:17And that's because when I get sick, I increase my oxidative stress and vitamin C
- 34:22is going to help reduce that oxidative stress.
- 34:25And somehow it's going to make me healthier or it's going to offset the cold and make the cold go away faster.
- 34:33And we found out that that's not true.
- 34:36There is no empirical evidence to support those two things.
- 34:43Now there's this add zinc to diet when you get the cold.
- 34:48And you do, and you may need more zinc when you are sick,
- 34:52as zinc is a co-factor that comes into play with immune function and regulation of oxidative stress,
- 34:59as well as activation of some enzymes within the immune pathways.
- 35:04But once again, you don't need excessive amounts of it.
- 35:07And the problem is that all of the supplements that are out there tend to have excessive amounts of all of these substances.
- 35:14And so why is it that having too much is a bad thing?
- 35:19And that's simply because they're going to try to make stable molecules
- 35:24in the same way that the radicals are going to try to make stable molecules.
- 35:28And in doing this, they're going to create more radicals within the cells
- 35:33and within the body than what would have been there normally.
- 35:35And so why is exercise going to control ROS formation?
- 35:42And once again, it doesn't matter what type of exercise that we do,
- 35:45whether it is body weight exercising or endurance exercise
- 35:53or weightlifting, resistance to weight lifting,
- 35:58or resistance training.
- 36:04It doesn't matter how we exercise.
- 36:07Exercise is going to help control ROSs,
- 36:09is going to help control ROSs by regulating mitochondrial functions
- 36:15and by generating additional antioxidant molecules coming away from the mitochondria.
- 36:22But beyond that, exercise is going to help control the mitochondria.
- 36:27And in doing that, exercise is going to help with controlling ROSs
- 36:31by increasing a few things and decreasing a few things.
- 36:35It's going to increase the antioxidants coming away from the mitochondria.
- 36:41It's going to help with increasing the clearance of lipids
- 36:45and nitrogenous oxidizers from the blood.
- 36:48It's going to start metabolizing those
- 36:50and creating the chance for those molecules to become free radicals.
- 36:57It's going to increase the conversion of the low density lipoproteins
- 37:01to the high density lipoproteins.
- 37:04And that has to deal with what the lipoproteins are doing for the body
- 37:08in terms of moving things around, which we'll talk about in a different talk.
- 37:15By increasing the rate at which metabolism is taking place during exercise
- 37:19by increasing the flow rate of blood around the body
- 37:24and excretion of materials either onto the skin through sweat
- 37:30or by increasing the filtration of blood
- 37:33following exercise at the kidneys or at the liver,
- 37:36we're able to clear things that might become free radicals.
- 37:41But we're also able to reduce the things that can become free radicals.
- 37:46And that is key point here.
- 37:48We're going to decrease stuff as well.
- 37:52We're going to decrease inflammation signals.
- 37:54If I can decrease inflammation signals, I decrease the hormonal signals
- 37:58that can lead to free radical formations.
- 38:03And by reducing inflammation signals, I'm able to increase
- 38:10my level of health and reduce my level of oxidative levels.
- 38:15My level of oxidative stress.
- 38:19So why do I need to avoid alcohol?
- 38:25Why do I need to avoid trans fats?
- 38:28It's not about what's happening at the tissues within the body.
- 38:31It's about what's happening specifically at one spot, and that's at the liver.
- 38:35It's all about what's happening at the liver in terms of metabolism in the liver
- 38:40that's attempting to quote unquote detoxify and eliminate metabolic wastes.
- 38:48And what is happening within the liver is that we're going to have a whole host
- 38:51of metabolic functions that come into play here.
- 38:55And as the metabolic functions that come into play, we're going to produce waste products
- 39:03and we're going to produce super oxides and free radicals.
- 39:07When we look at the production of the super oxides and we look at the production of the
- 39:12free radicals, all of these things will be eliminated from the body.
- 39:16They're either going to be eliminated from the body through transportation to the sweat
- 39:19glands to be released as sweat, transportation to the kidneys to be released as urine,
- 39:26or are going to go into the formation of bile to be excreted into the intestines
- 39:32to be eliminated from the body to be removed from the body during defecation.
- 39:39Now, if you look here, we have distinct free radicals that are going to form.
- 39:45And the distinct free radicals are forming is based off of the rate of the transformation steps.
- 39:54The rate at which we are undergoing reactions to the body is going to be
- 39:59the rate at which we are undergoing reactions of the toxic material of the metabolites in circulation
- 40:10that are going to lead to super oxides and free radicals,
- 40:14ROSs, RNs, RSSs.
- 40:18And what we're going to attempt to do is we're going to attempt to use our enzymes
- 40:22and our coenzymes and our cofactors in an attempt to temporarily bind onto these radicals.
- 40:29And there's a reason why I want to bind onto these radicals,
- 40:32because we want to reduce oxidative stress within the liver cells.
- 40:39We want to reduce the oxidative stress within the liver cells until we can get these
- 40:42molecules out of the liver and out of the body.
- 40:48And that's because when we have an excessive amount of metabolic stress taking place within
- 40:55the liver, we end up having oxidative stress injury.
- 41:00And oxidative stress injury triggers an inflammatory response taking place within the liver itself.
- 41:06And this inflammatory process within the liver is going to activate a specific type of cell,
- 41:12what's sometimes referred to as a stellate cell.
- 41:14And what the stellate cell does is it starts to cause clots to form within
- 41:19a region of the liver known as the sinusoid.
- 41:23And what this does is this causes a blockage of flow in an attempt to protect the hepatocytes,
- 41:29the liver cells, from experiencing any type of additional injury.
- 41:37And what this clot formation ends up doing is it ends up blocking the cell
- 41:41and what this clot formation ends up doing is it ends up blocking blood flow through the liver.
- 41:48But the problem is that blood flow is going to keep coming into the liver
- 41:52and it's going to cause additional stress.
- 41:55And the additional stress is going to cause additional activation of stellate cells,
- 42:00which is going to cause additional activation of the clotting issues that take place,
- 42:05which leads to something known as fibrosis.
- 42:07Fibrosis, if it becomes excessive, is where oxidative stress within the liver itself
- 42:14leads to cirrhosis.
- 42:16This is where we can get two distinct types of cirrhosis or two distinct types of liver
- 42:21diseases taking place due to oxidative stress.
- 42:25It can come about from excessive consumption of ethanol, alcohol,
- 42:32which is referred to as alcohol fatty acid liver syndrome,
- 42:38or it can come about from excessive consumption
- 42:44of non-alcoholic factors, which will lead to oxidative stress,
- 42:51which include things like excessive consumption of trans fats,
- 42:55excessive consumption of carbohydrates, in particular fructose-based carbohydrates.
- 43:04And fructose is one of the units of the sugar that we find within table sugar, sucrose,
- 43:12is the table sugar, which is made up of a glucose and a fructose.
- 43:17If I'm consuming a large amount of sugar,
- 43:20I'm going to be consuming a large amount of fructose. If I'm consuming large amounts of
- 43:24things that have what's usually as high fructose syrup,
- 43:27the most prominent type of high fructose syrup is high fructose corn syrup,
- 43:33which adds just a few percentages more fructose than what we get from normal sucrose.
- 43:41But what that does is that causes additional oxidative stress to the liver,
- 43:45which triggers additional activation of stellate cells, which causes that same type of fatty acid
- 43:50issue to develop, leading to possible cirrhosis of the liver, all due to fibrotic changes,
- 43:58clotting, in an attempt to save the hepatocytes from having additional oxidative stress.
- 44:07So, what we're seeing is that the liver is not going to be able to
- 44:10save the hepatocytes from having additional oxidative stress.
- 44:17And so, if I'm able to consume additional amounts of
- 44:24the enzymes, coenzymes, and cofactors necessary to limit the amount of oxidative stress taking
- 44:32place within the liver as the liver is doing its detoxification reactions,
- 44:37I'm going to be able to limit the amount of either fatty acid, not to be non-alcoholic fatty acid,
- 44:46or alcoholic fatty acid liver issues coming about within the liver, leading to the fibrosis
- 44:53and the eventual cirrhosis that can take place within the liver disease issues.
- 44:59And this is where, if I'm eating large amounts of trans fats, if I'm eating large amounts of high
- 45:06sugar, if I'm consuming large amounts of alcohol, but I'm not counterbalancing that with the
- 45:14consumption of antioxidants, I'm going to have the excessive oxidative stress taking place
- 45:20and the potentiation to have cirrhosis or anti-oxidation.
- 45:26And the potentiation to have cirrhosis or I'm going to have an increased relative risk for developing cirrhosis.
- 45:37Okay. We also said something about avoid smoking. Well, why do I need to avoid smoking? Now, here's the thing.
- 45:45Most of the smoking research is strictly about tobacco smoke.
- 45:49But we have recently noticed with the change in materials being smoked that it doesn't matter
- 45:56what is being smoked, whether it is tobacco smoke, hemp smoke, or the vape smoke, the electronic
- 46:05e-cigarettes or the vape pens. It doesn't matter what's being smoked. All of them are going to
- 46:11increase oxidative stress within the respiratory tract, within the lungs, within the trachea,
- 46:20and within the bronchioles. And what this is going to do is this is going to trigger inflammation
- 46:25within the respiratory tract, but it's also going to be able to be absorbed very quickly because of
- 46:31the types of cells that we have within the lungs, which is going to trigger ROS and radical formations
- 46:38outside of the lungs by triggering immune activity within the respiratory tract.
- 46:46We're going to get high amounts of inflammation taking place within
- 46:49the lungs, high amounts of inflammation taking place within the respiratory tract
- 46:53due to what's referred to as the volatile chemicals that we see within the smoke material.
- 47:00When we say volatile chemicals, what we're talking about is we're talking about chemicals that are
- 47:04airborne. And so a lot of times we can actually see the same type of issue come about
- 47:14from people who are exposed to things that are very similar to smoke but are not actual smoking
- 47:23things. So people who are exposed to car exhaust and large amounts of car exhaust, people who
- 47:31are firefighters that are exposed to burning buildings or anything that happens to be combustible,
- 47:41auto mechanics, people who go to auto racing, are exposed to large amounts of exhaust of
- 47:50burnt hydrocarbons, burnt fuels that increase the volatile chemicals in the air that can trigger
- 47:57the same ROS issues that can come about from smoking. It's one of the reasons why if you're
- 48:04an outdoor exerciser like myself, you want to make sure you look at the air quality index
- 48:10relative to when you plan to go and work out outside and modulate your activity based off
- 48:15of what the air quality index is telling you because that's the indication of the level of
- 48:20volatile chemicals in the area that you're going to be exercising in. And what's that oxidative
- 48:26stress going to lead to? The oxidative stress is going to lead to the cancers, lung cancer,
- 48:33respiratory cancer, COPD, chronic obstructive pulmonary diseases, emphysema. We could see
- 48:41things like bronchitis come about. We could see things like asthma come about. Asthma is
- 48:46an immune response and the more oxidative stress that I have taking place, the more likely I am
- 48:51to have an asthmatic response taking place. If you can't avoid trans fats, if you can't avoid
- 48:58trans fats, if you over consume alcohol or if you cannot avoid over consuming alcohol,
- 49:07if you can't avoid smoke, and remember it's not just about you being the smoker, it's avoiding
- 49:13the smoke, then we know that taking the antioxidants might be of benefit to you. Things to remember
- 49:21in terms of a take home message. Illnesses lead to increased ROSs, but consuming antioxidants does not
- 49:29prevent illnesses. Vitamin C and zinc do not prevent getting the common cold. Poor physical
- 49:40activity leads to increased ROSs by increased inflammation due to issues referred to as over
- 49:48fatness. These issues are countered by increase of activity independent of any changes that we
- 49:57might see in body weight or body composition. What we have to remember here is that health
- 50:03issues are highly complex and to attribute health to a single factor is an oversimplification
- 50:15health issues are highly complex and to attribute this to a single factor is an oversimplification
- 50:25and a misrepresentation of the principles of science.
- 50:29We have a number of issues that will feed onto each other and interact with each other,
- 50:37leading to one's overall health. And because of the way in which the body functions and the way
- 50:47in which we function interact with others within our environment, it is almost impossible to
- 50:54indicate a single factor as the root cause for any of the health issues or as the underlying
- 51:02principle reason for alleviating health issues. Well, thanks for watching. Thanks for listening.
- 51:09Hopefully you gained a little insight into some of the aspects of human physiology and health
- 51:15that gets misrepresented within a lot of the issues that we're going to be discussing today.
- 51:22That gets misrepresented within a way the way in which we talk about stuff. If you like what we
