Latest / Hardiness with Dr Paul Taylor / Wisdom Wednesdays: Artificial Sweeteners - Healthy Sugar Alternatives Or Sweet Poison?
Transcript
- 0:09Speaker 1: Hey, everybody, welcome to another edition of Wisdom Wednesdays. Today,
- 0:13Speaker 1: we are diving into a topic that has been gaining
- 0:15Speaker 1: a lot of attention recently, and it's that of sugar substitutes. Now,
- 0:21Speaker 1: you probably heard about all the benefits of swapping out
- 0:25Speaker 1: sugar for zero calorie alternatives, and lots of people do
- 0:29Speaker 1: that because they're trying to lose weight. But all these
- 0:32Speaker 1: sugar substitutes really as harmless as they're made out to be. Well,
- 0:36Speaker 1: today we're going to explore what they research actually says.
- 0:41Speaker 1: So first off, let's talk about what sugar substitutes actually are.
- 0:45Speaker 1: So they are either low calorie or no calorie alternatives
- 0:50Speaker 1: designed to replace sugar and everything from your morning coffee
- 0:54Speaker 1: to lots of different types of baked goods, and some
- 0:57Speaker 1: of the most common ones you'll have heard of asperteam sucralow, saccherin.
- 1:03Speaker 1: And then there's a class of things called sugar alcohols
- 1:06Speaker 1: like aerythtratol and xylotol. Now they're often tided as being
- 1:12Speaker 1: see if and actually recommended for diabetics because they don't
- 1:15Speaker 1: spike your blood sugar levels, but emerging research suggests that
- 1:20Speaker 1: their effects on our health might be much more complex
- 1:24Speaker 1: than that and much more harmful potentially than we once thought.
- 1:29Speaker 1: So let's start with aspartam That is one of the
- 1:32Speaker 1: most widely used artificial sweeteners in the world. But the
- 1:37Speaker 1: World Health Organization recently made headlines when it classified aspartain
- 1:43Speaker 1: as a possible car synogen. Now, this label means that
- 1:47Speaker 1: there's some evidence that aspar team could increase the risk
- 1:50Speaker 1: of cancer, although it's not completely definitive, and the World
- 1:55Speaker 1: Health Organization's decision was based on a review of several studies,
- 1:59Speaker 1: including long term research, that linked aspartain consumption to increase
- 2:03Speaker 1: risk of certain cancers, particularly liver and lung cancers in
- 2:07Speaker 1: animal models, and some people, particularly those who have been
- 2:12Speaker 1: nudged by the sugar industry or the sugar industry themselves,
- 2:15Speaker 1: have criticized those models in saying that some of the
- 2:19Speaker 1: studies the animals, we're giving very very high amounts of aspertain.
- 2:24Speaker 1: But that is a way that we actually do things
- 2:28Speaker 1: to try and understand mechanisms, right, But let's leave that
- 2:31Speaker 1: to the side for a minute. Let's talk about erythratol.
- 2:34Speaker 1: So this is an increasingly popular sugar alcohol that's used
- 2:39Speaker 1: in many natural sweeteners like stevia and monk fruit. So
- 2:44Speaker 1: I've read lots of stuff about using stavia. Monk fruit
- 2:48Speaker 1: is really beneficial for our health because it looks like sugar,
- 2:52Speaker 1: it tastes like sugar, and it can be used for baking.
- 2:55Speaker 1: But it has been in a spotlight recently due to
- 2:59Speaker 1: some pretty alarming findings. So a pilot study, and we
- 3:04Speaker 1: do need to be a word, it's only a pilot
- 3:05Speaker 1: study from the Cleveland Clinic in the United States found
- 3:10Speaker 1: that erythritol could more than double the risk of blood
- 3:13Speaker 1: clotting in healthy individuals. So the study was led by
- 3:18Speaker 1: lead author doctor Stanley Hazen, and he's the director of
- 3:22Speaker 1: the Center for Cardiovascular Diagnostics and Prevention at the Cleveland
- 3:27Speaker 1: Clinic Learner Research Institute. Jesus, that's a bit of a
- 3:31Speaker 1: worthy title, isn't it. But he noted that in the study,
- 3:35Speaker 1: consuming a drink with an equal amount of glucose or
- 3:40Speaker 1: sugar did not affect blood platelet activity in a control
- 3:44Speaker 1: group of ten people, but that in every single subject
- 3:49Speaker 1: that had a drink with erythratol in it, every single
- 3:52Speaker 1: measure of cleatelet responsiveness known as clotting went up. Following
- 3:57Speaker 1: the ingestion and this worrying to Stanley, hazard is the
- 4:01Speaker 1: first direct head to head comparison of the effects of
- 4:05Speaker 1: ingesting glucose versus ingesting erythritol on multiple different measures of
- 4:11Speaker 1: platelet function. And he stated that glucose doesn't impact upon
- 4:16Speaker 1: clotting in the body, and this is human bodies, but
- 4:19Speaker 1: a erythritol actually does. Now, interestingly, the amount of the
- 4:23Speaker 1: erythritol used an each drink in the study was thirty grams,
- 4:28Speaker 1: and that is reasonably equivalent of what you find included
- 4:32Speaker 1: in typical sugar free soft drinks or ice creams or muffins,
- 4:36Speaker 1: of which people often have more than one serving. Now,
- 4:39Speaker 1: these clots are an issue because they can travel to
- 4:42Speaker 1: the heart of the brain, leading to heart attacks or strokes.
- 4:46Speaker 1: And this research is particularly troubling because a erythritol is
- 4:49Speaker 1: very widely used as a sugar substitute, particularly in keto
- 4:54Speaker 1: friendly products or low sugar products, which are generally consumed
- 4:58Speaker 1: by people who are trying to manage the way at
- 5:00Speaker 1: other blood sugar levels or their health in general. Now,
- 5:04Speaker 1: we should note that this was just a pilot's study,
- 5:07Speaker 1: but the very good design of the study that there
- 5:10Speaker 1: was a control group as well that was drinking glucose.
- 5:13Speaker 1: Plus the fact that the clotting markers went up in
- 5:16Speaker 1: every single one of the subjects consuming erythrotol, and the
- 5:20Speaker 1: fact that it's a human study, not an animal study.
- 5:23Speaker 1: This is enough to convince me never to use that stuff. Now.
- 5:27Speaker 1: Beyond a erythrotol, other studies have shown that different sugar
- 5:30Speaker 1: substitutes have their own sets of risks. So, for example, sugarlose,
- 5:34Speaker 1: which is another common sugar substitute that has actually been
- 5:38Speaker 1: shown to reduce insulin sensitivity in some people, which could
- 5:44Speaker 1: then ironically increase the risk of developing diabetes, the very
- 5:49Speaker 1: condition that these sweeteners were supposed to help manage. And
- 5:54Speaker 1: then saccharin, which is one of the oldest artificial sweeteners.
- 5:57Speaker 1: I remember my mum when I was a little kid,
- 5:59Speaker 1: put saccharine in our tea that was at one point
- 6:03Speaker 1: linked to bladder cancer in animals, although later research in
- 6:06Speaker 1: humans didn't confirm these findings. But there is a common
- 6:12Speaker 1: feature with these things. Now, let's talk about the mechanisms
- 6:15Speaker 1: of action of artificial sweetness. For me, one of the
- 6:18Speaker 1: most concerning aspects of sugar substitutes in general is their
- 6:22Speaker 1: impact on the gut microbiome, that really important community of
- 6:26Speaker 1: bacteria that lives in our digestive system and plays their
- 6:30Speaker 1: crucial role in our overall health. And numerous studies have
- 6:35Speaker 1: actually shown that artificial sweeteners like sucralose and saccharine and
- 6:40Speaker 1: others can alter the balance of gut bacteria, which then
- 6:45Speaker 1: contributes to the development of metabolic disorders like insulin resistance,
- 6:50Speaker 1: diabetes and other metabolic disorders. So, for instance, a study
- 6:54Speaker 1: published in Nature, which is one of the top journals
- 6:57Speaker 1: in the world, that found that these sweetness could induce
- 7:01Speaker 1: glucose intolerance, a precursor to diabetes, by disrupting the gut microbiome.
- 7:07Speaker 1: So for me, there's a bigger picture really about our
- 7:11Speaker 1: metabolic health, and what's becoming increasingly clear is that sugar
- 7:15Speaker 1: substitutes aren't the benign alternatives that we once thought they were.
- 7:20Speaker 1: They might help to reduce calorie intake in the short term,
- 7:23Speaker 1: and they certainly do, but the long term consequences could
- 7:26Speaker 1: be far more damaging. And for me, it's the combination
- 7:31Speaker 1: of proven disruption of the gut microbiome and increased risk
- 7:35Speaker 1: of metabolic diseases and the potentially carcinogenic effects, and now
- 7:41Speaker 1: the potential effects on clutting. That really says that we
- 7:45Speaker 1: need to be extremely cautious about this stuff. And even
- 7:49Speaker 1: more concerning is that these sweeteners are often consumed in
- 7:53Speaker 1: combination with other unhealthy dietary choices such as ultra processed food,
- 7:58Speaker 1: Like you don't find the sweeteners in real food, and
- 8:02Speaker 1: that really exacerbates their negative effects. And I've talked about
- 8:06Speaker 1: ultra processed food, and it's not just the sweeteners, but
- 8:10Speaker 1: it's also things like a multifiers, flavorings, and also preservatives
- 8:17Speaker 1: that when you put them in together, just completely messes
- 8:21Speaker 1: with our biology. So words that leave us. While sugar
- 8:25Speaker 1: substitutes might offer some short term benefits for reducing calories
- 8:30Speaker 1: and managing our way our thinking that you could manage diabetes,
- 8:35Speaker 1: for me, the potential long term risks definitely is pointing
- 8:39Speaker 1: to outweighing these advantages. And the research still needs to evolve,
- 8:44Speaker 1: but for me, it's becoming increasingly clear that these artificial
- 8:49Speaker 1: sweeteners are things that we should stay away from, or
- 8:53Speaker 1: at least not have a lot of, and the best
- 8:57Speaker 1: way to do that is to reduce our concer umption
- 9:00Speaker 1: of ultra processed foods. If you look at a food
- 9:02Speaker 1: and it hasn't been alive, then it probably isn't good
- 9:06Speaker 1: for you. And again, I think a key thing for
- 9:10Speaker 1: us to do is to try and wean ourselves off
- 9:14Speaker 1: this real addiction to sugar. And we need to realize
- 9:18Speaker 1: that really in nature, it's stuff like fruit and honey.
- 9:22Speaker 1: But even the fruit that we have today is much
- 9:25Speaker 1: sweeter than natural fruit because it has been bread to
- 9:29Speaker 1: be much sweeter. And then when you eat these ultra
- 9:31Speaker 1: processed foods, they are super super sweet. So when kids
- 9:36Speaker 1: then are eating lots of those, it recalibrates what sweetness
- 9:40Speaker 1: actually is. So I think the longer term strategy needs
- 9:44Speaker 1: to be getting off the sugar. And I remember twenty
- 9:47Speaker 1: thirty thirty years ago, actually I used to drink sugar
- 9:50Speaker 1: in my tea and I went off it and I
- 9:52Speaker 1: just committed to drinking no sugar in my tea for
- 9:56Speaker 1: two weeks, and it was disgusting for the first week,
- 10:00Speaker 1: and then actually it tasted fine, and there's no way
- 10:03Speaker 1: that I kind of sugar in my tea. As well.
- 10:06Speaker 1: The other thing that I did, I've got a bit
- 10:07Speaker 1: of a sweet tooth, and I used to eat milk
- 10:09Speaker 1: chocolate and I switched completely the dark and then after
- 10:12Speaker 1: a few weeks I couldn't eat milk chocolate again. So
- 10:15Speaker 1: we can get ourselves off this bandwagon, and for me,
- 10:20Speaker 1: that's a much more effective strategy than just using these
- 10:24Speaker 1: sugar substitutes that we really are starting to see and
- 10:29Speaker 1: now I are not what we thought they were. So
- 10:32Speaker 1: that's it for this week. Catch you next time, folks,
