Wisdom Wednesdays: We're getting cancers at a younger age globally - and scientists think they know why. Here's what you can do... · Hardiness with Dr Paul Taylor

  Speaker 1: Everyone, Welcome to another edition of Wisdom Wednesdays. Today we
• 0:13
  Speaker 1: are going to investigate why the age of onset of
• 0:17
  Speaker 1: a lot of cancers seemed to be getting younger, and
• 0:21
  Speaker 1: it appears to be an almost global phenomenon. Now, you
• 0:25
  Speaker 1: may have seen in the news a few months ago
• 0:28
  Speaker 1: there was a headline doing the rhymes that showed an
• 0:31
  Speaker 1: explosion in bil cancer incidents in the under fifties. And
• 0:35
  Speaker 1: one of the leading theories as to why this was
• 0:38
  Speaker 1: occurring was the declining quality of our diets and specifically
• 0:43
  Speaker 1: the huge increase in ultra process food consumption. And the
• 0:47
  Speaker 1: thinking was that there were twin drivers. The crap that's
• 0:51
  Speaker 1: in ultra processed foods, such as flavor enhancers and multifiers
• 0:56
  Speaker 1: and preservatives that we know now damage the lining and
• 1:01
  Speaker 1: create an unhealthy microbiome. And then there's the double wamy
• 1:06
  Speaker 1: of the crowding out of nutritious food that feeds a
• 1:10
  Speaker 1: positive microbiome and a healthy cut lining. Clearly, if you're
• 1:14
  Speaker 1: eating more crap food, you're eating less healthy food, so
• 1:17
  Speaker 1: we get this double wammy effect. Now, this week I
• 1:21
  Speaker 1: read a thought provoking article from the Journal of the
• 1:25
  Speaker 1: American Medical Association Oncology that highlights increased rates of many
• 1:31
  Speaker 1: different cancers in younger people, and it actually explores what's
• 1:37
  Speaker 1: going on and whether or not that these increased cancers
• 1:42
  Speaker 1: in young people are actually a symptom of accelerated biological aging.
• 1:48
  Speaker 1: So let's start with the background. Traditionally, cancer has been
• 1:51
  Speaker 1: a disease that we associate with older age, but recently
• 1:56
  Speaker 1: there's been a noticeable bump or a spike in cancer
• 2:00
  Speaker 1: diagnosis among people under fifty. And we're not just talking
• 2:03
  Speaker 1: about borl cancer that I mentioned earlier. It's also breast cancer,
• 2:07
  Speaker 1: pancreas cancer, kidney cancer, and even head and neck cancers.
• 2:12
  Speaker 1: It appears to be global. It's growing, and it's affecting
• 2:16
  Speaker 1: millennials and Gen zs born in the eighties and the nineties. Now,
• 2:21
  Speaker 1: in this article, they actually suggested that some of the
• 2:25
  Speaker 1: usual suspects explain this, things like poor diets, sentary living, pollution,
• 2:33
  Speaker 1: increased microplastics, and even antibiotic overuse. Now, what if these
• 2:39
  Speaker 1: cancers aren't just random or lifestyle driving, but what if
• 2:43
  Speaker 1: they're actually assigned that these people are biologically older than
• 2:49
  Speaker 1: their birth certificates suggest So, as you will be well
• 2:53
  Speaker 1: were chronologically is the number on your birthy cake, and
• 2:57
  Speaker 1: it's a blunt instrument. Biologically, is is what's happening underneath
• 3:02
  Speaker 1: the hoot how your sales, tissues and organs are actually functioning.
• 3:08
  Speaker 1: And twenty years ago I actually developed a biological age
• 3:12
  Speaker 1: test and that was used in lots of gyms that
• 3:15
  Speaker 1: basically give people a needs and based on their fitness
• 3:19
  Speaker 1: and strength levels. But more recently there's been a lot
• 3:23
  Speaker 1: of these biological aging clocks that you may be aware of.
• 3:27
  Speaker 1: I've talked about some of them that look at the
• 3:31
  Speaker 1: aging of cells and different processes in a body, epigenetic
• 3:35
  Speaker 1: markers and all of these sorts of things, things like
• 3:39
  Speaker 1: grimm AADs that are out there and they're now used
• 3:41
  Speaker 1: in lots of research studies. So these studies show that
• 3:44
  Speaker 1: two people can both be forty, but one may have
• 3:49
  Speaker 1: a biological age of a sprightly thirty five and the
• 3:52
  Speaker 1: other are weary forty eight. And it's kind of like
• 3:56
  Speaker 1: comparing at twenty ten Toyota Corolla. It's been lovingly serviced
• 4:01
  Speaker 1: and driven by one very careful owner to one that's
• 4:05
  Speaker 1: been doing laps in a dirt track in the outback.
• 4:09
  Speaker 1: So when we see thirty five year olds being diagnosed
• 4:12
  Speaker 1: with cancers we normally associate with people in their sixties.
• 4:16
  Speaker 1: Maybe they're just aging faster. And here's a concept that
• 4:21
  Speaker 1: I loved that was outlined in the paper, the expose home,
• 4:25
  Speaker 1: and it is the total sum of everything your body's
• 4:29
  Speaker 1: being exposed to over time. Crap, food, pollution, stress, poor sleep,
• 4:36
  Speaker 1: poor social conditions, financial stressors. It's the whole chaotic buffet
• 4:42
  Speaker 1: of modern life. And if the exposed home has gone
• 4:46
  Speaker 1: off the reels by ultra processed diets, chronic stress, loneliness,
• 4:52
  Speaker 1: even trauma, lack of physical activity, all of this speeds
• 4:56
  Speaker 1: up your internal war intern and that's what's by accelerated aging.
• 5:01
  Speaker 1: And you will be aware that I have talked about
• 5:05
  Speaker 1: the different hallmarks of aging, and here's the thing. Aging
• 5:09
  Speaker 1: and cancer share many of the same biological pathways, and
• 5:14
  Speaker 1: some of those I covered in that series on the
• 5:17
  Speaker 1: twelve Hallmarks of aging, the ones where there's a very
• 5:20
  Speaker 1: very clear overlap or things like DNA damage that's the
• 5:24
  Speaker 1: big one, and mitochondrial dysfunction inflammation. Tellome are shortening, and
• 5:30
  Speaker 1: their suggesting is that some of the others may be
• 5:33
  Speaker 1: affected as well. So if you're aging faster at a
• 5:37
  Speaker 1: cellular level cancer might not wait until retirement to come knocking.
• 5:43
  Speaker 1: So here's the thing that we can all act on. Right,
• 5:46
  Speaker 1: the same behaviors that slow aging can actually help prevent
• 5:52
  Speaker 1: cancer if we flip them in terms of the impact
• 5:56
  Speaker 1: that we're having on them, or they are the behaviors
• 5:59
  Speaker 1: that we're having. So we're talking here in terms of
• 6:02
  Speaker 1: reducing aging and reducing your risk of cancer, doing regular exercise,
• 6:08
  Speaker 1: having caloric moderation. So I don't mean starvation, I just
• 6:12
  Speaker 1: mean not overeating. And we are a society of overfed
• 6:17
  Speaker 1: and undernourished individuals. What I mean by that is we're
• 6:21
  Speaker 1: consuming too much calories and their crappy calories, so our
• 6:25
  Speaker 1: nourishment is actually going down. That affects many of our
• 6:29
  Speaker 1: cellular processes. The third one is avoiding smoking, avoiding binge
• 6:35
  Speaker 1: drinking then would be the fourth one. Then it's about
• 6:39
  Speaker 1: minimizing unmanageable stress, not the stress that helps us to adapt,
• 6:44
  Speaker 1: but the stuff that actually breaks us down. And then
• 6:48
  Speaker 1: it's about building strong social networks, because we know that
• 6:52
  Speaker 1: loneliness is shocking for your health, but having good social
• 6:56
  Speaker 1: networks is actually very good for your health. And then
• 7:00
  Speaker 1: exposure to nature, having good sleep, having a sense of
• 7:04
  Speaker 1: meaning and purpose in your life. Basically, the lifestyle that's
• 7:08
  Speaker 1: good for your brillan, your mood and telomeres is also
• 7:12
  Speaker 1: the best defense against these early onset cancers. And there's
• 7:17
  Speaker 1: even this whole field emerging called gyro science which looks
• 7:22
  Speaker 1: at slowing aging itself as a way to prevent a
• 7:26
  Speaker 1: host of diseases, cancer included. So what does this mean
• 7:30
  Speaker 1: for all of us? Well, maybe it's time we started
• 7:33
  Speaker 1: looking before the age of fifty as the magic number
• 7:37
  Speaker 1: for cancer screening as it typically is right now, Maybe
• 7:41
  Speaker 1: we need biological age based guidelines because if you're thirty
• 7:44
  Speaker 1: eight but your biology is more like fifty eight, you
• 7:47
  Speaker 1: should probably be screened sooner. And it also means that prevention,
• 7:51
  Speaker 1: the fundamental stuff that I talk about all the time,
• 7:54
  Speaker 1: like movement, nutrition, connection, sleep, it is more powerful forever.
• 8:00
  Speaker 1: It's not just about how long we live, but how
• 8:03
  Speaker 1: soon before disease shows up. And the data in Australia
• 8:07
  Speaker 1: and other countries is showing that people are getting chronic
• 8:12
  Speaker 1: disease earlier and early. It's not just cancer. And this
• 8:15
  Speaker 1: basically say is that we are aging at a much
• 8:19
  Speaker 1: faster rate than we were decades ago. So the new
• 8:24
  Speaker 1: longevity mindset's not just about living longer, it's about not
• 8:28
  Speaker 1: breaking down too early. It's about increasing your health span.
• 8:32
  Speaker 1: So the big takeaway here is if early onset cancer
• 8:35
  Speaker 1: is a sign of accelerated aging, which it does appear
• 8:38
  Speaker 1: to be, then our day to day choices are more
• 8:41
  Speaker 1: than just healthy habits. They're actually investments in cancer prevention.
• 8:46
  Speaker 1: And we don't need to live like monks, but we
• 8:49
  Speaker 1: do need to pay attention to the life that we're
• 8:52
  Speaker 1: living inside of our body. And I think the big
• 8:54
  Speaker 1: thing here is really around kids, because the kids who
• 8:59
  Speaker 1: are walking around these days eating crap diets, not moving
• 9:03
  Speaker 1: very much and overwegh it. As young children and teenagers,
• 9:09
  Speaker 1: they will definitely be getting cancer and other diseases much
• 9:12
  Speaker 1: sooner than their parents. So on that tragic note, that's
• 9:17
  Speaker 1: it for me for this week. Catch you next time.
