25 Year Old Study Finds Low Carb Diets Linked To Earlier Death

Eric Bakker here. Thanks for coming back. I’m the naturopath from New Zealand. We’re going to talk about low carb diets and
longevity. So there are a few things that really tweak
people’s attention when it comes to studies, but longevity is a big one. Participation, especially longterm participation,
is important. A lot of studies you’ll read only went for
four weeks or six weeks, involving groups, cohorts, of maybe a hundred or a couple of
hundred people. What we’re going to show you now is a 25-year
study published in The Lancet Public Health, brings into question the healthiness of restricting
carbohydrates from the diet. So what we’ve done is look for 25 years at
the health of people restricting carbs, not just five minutes like what’s happening with
keto today. So all those carnivores and keto, especially
hardcore keto people, need to sit back and listen carefully to the video, all right,
because this is, again, a 25-year study. Sara Seidelmann, from The Division of Cardiovascular
Medicine at Brigham and Women’s Hospital in Boston, and colleagues, studied 15,400 Americans
over 25 years to better understand how their dietary choices affected their mortality rates. They found that people that consumed a moderate
level of carbs, 50%, at age 50 can expect to add another 33 years to their life. By contrast, the high carb eaters, so more
than 70% of the diet being carbohydrates, lived another 32 years. But the low carb eaters, under 40%, added
29 years to their lives. So you could see a four year difference there
between the moderate and the low carb eating. So if you are looking at a higher life expectancy,
you’re not going to get it on a low carb diet, okay. It’s just not going to pan out that way and
the research is showing that. Many studies are showing that when you limit
carbs, you create problems longterm with your gut because you’re going to change the biodiversity
of the gut. This isn’t the only study, however, to confirm
this data, okay. As the researcher writes, “These findings
reflect a U-shaped relationship between carb intake and mortality and were corroborated
by data from a North American, European and Asian and multinational cohorts combined as
part of a meta analysis.” So this is a large amount of research that’s
pooled together is showing that low carb diets reduce life expectancy of people. Unfortunately for carnivores, the type of
protein and fat you’re eating does matter. The team found that excessive meat and dairy
shorten lifespans. They speculate this is due to the decreased
amount of vegetable intake, there you go, because what you’re doing is you’re reducing
the biodiversity of the microbiome. You’re putting a lot more fat in there. You’re also putting more herbicides and pesticides,
hormone preparations, antibiotics. You don’t usually inject antibiotics into
cauliflower but you often inject them into animals, so unless you’re getting 100% free
range, I’d be very careful. But it also says it doesn’t leave vegans off
the hook either. The team found that high carbohydrate intake
of processed foods and staples like rice increase the risk of mortality. So, like Michael Pollan says, the well-known
Michael Pollan, “Eat food. Not too much. Mostly plants.” Okay. Plant based diets have proven to extend the
lifespan of many people. If you look at the five Blue Zones, okay,
you will see, for example, if you look at Sardinia in Italy, you’ll see that the carb
intake, I think, is around 45 to 55%, and they drink a lot of wine, okay? They do a lot of things that all these crazy
bloggers would think they’d die from, but in fact, people in Sardinia, one in three
live beyond 90. So you’ve got to remember that it’s all about
lifestyle and diet and moderation. It’s all about balance. So this whole thing about carbs, this article
I’m reading says, makes the realm of nutrition confusing. The proliferation of food blogging sites dedicated
to dieting and cleansing leaves the public truly dazed, all right. Many people are confused about carbs, but
let’s just take away all that confusion, and there’s no doubt in my mind that when you
restrict carbs, you’re going to restrict your life down the track. Think about the diversity of the gut. Don’t just think about big your butt is. Think about how long your lifespan is going
to be, too. Thanks for tuning in.
