Doubling Saturated Fat In Diet Does Not Increase It In Blood 252

Posted by Soulskill from the reasons-to-eat-a-stick-of-butter dept.
An anonymous reader writes: A new study by researchers at Ohio State University found that dramatically increasing the amount of saturated fat in a person's diet did not increase the amount of saturated fat found in their blood. Professor Jeff Volek, the study's senior author, said it "challenges the conventional wisdom that has demonized saturated fat and extends our knowledge of why dietary saturated fat doesn't correlate with disease."

The study also showed that increasing carbohydrates in the diet led to an increase in a particular fatty acid previous studies have linked to heart disease. Volek continued, "People believe 'you are what you eat,' but in reality, you are what you save from what you eat. The point is you don't necessarily save the saturated fat that you eat. And the primary regulator of what you save in terms of fat is the carbohydrate in your diet. Since more than half of Americans show some signs of carb intolerance, it makes more sense to focus on carb restriction than fat restriction."

        it is amazing to me how SURE everyone is that carbs are bad for you.

        carbs are, traditionally, the bedrock of human consumption. Hell, we look at the start of society by farming of a carbohydrate source. And frankly, some of the longest living countries have diets where carbs form the backbone of caloric intake. There may be a huge issue with constantly spiking your blood sugar with sweets (i.e. the american way), but just a little thought would show you how ridiculous it is to claim that carbs are the grim reaper.

        Example, Japan. Diets here (I live there so will speak where I have direct experience) are extremely carb heavy. In fact, rice forms the backbone of your ENTIRE DAY. Literally every meal has rice as a central part of your caloric intake. Meats, on the other hand, even fish, are not as common. And very few foods outside of restaurants are high fat. Other places, like Italy, have a high carb, high fat diet.

        What do most of the long lived countries have in common? their total calorie intake is low! The one thing that has never had any question mark: caloric restriction is the best indicator for long life. Not carbs, not fats, not saturated fats, not any of those. Just eat less. And it will lower all you blood markers simultaneously. Or, if you want, work out a hell of a lot (not this 3 hour a week BS, I am talking 10-15 hours a week of intense exercise). Then you can basically eat anything and your markers will be amazing.

        else, you have to find the diet that works for your genetics. For some, that will be low carb. or some, that will be low fat.

      "Calories in, calories out" is given as a good first order approximation of reality for the purposes of weight loss (at least whenever I've seen it). This article isn't about weight loss, it's about health. It's obvious that being conducive to weight loss and being healthy are not synonymous. I could lose weight by eating nothing but cyanide.

      Now, it's true that even for weight loss "calories in, calories out" is only an approximation, but based on the admittedly small amount of information I have it is basically the most practically useful one, and using more complex models is counterproductive. Ultimately for most people trying to lose weight the most limiting factor is psychology. If you have some really nice theory about how different nutrients (or even exercise) affect weight differently, chances are you will be tempted to slack off on the by far much more important "calories in, calories out" equation, because you have a limited amount of mental energy. All the physiological tricks mean jack shit if you're inputting too much energy into yourself. Now of course what you eat still matters a lot, but mainly because it affects your psychology differently -- for instance, I've heard many anecdotal reports that 1200 calories from carbs leaves people feeling much less satisfied than the same amount from fat and protein, which of course is going to make it harder for a person not to eat any more. In other words, a corollary to "calories in, calories out" is "find whichever source of calories makes it easiest for you to maintain the equation", but even then physiology matters only in the way that it affects psychology, and not directly because some sources of calories are metabolized differently than others.

      So, apparently, more calories went out than in. Which also makes this a poor study. We know that weight loss improves health and risk markers in the blood.

But that question is incredibly specific to one person and very poorly defined beyond that. This study says in these very specific circumstances the answer is more fat and less carbs, but that's not necessarily true in general.

      Thanks for this list -- yes, it's important to note the limitations of this study.

      However, one broader issue that this study should point out is the continued stupidity of the medical profession in assuming that because the quantity of X in diet is increased, it will necessarily increase the quantity of X in one's blood or other chemical markers.

      We've seen this for many years with cholesterol studies -- the body manufactures most cholesterol, so dietary consumption has little relation to blood cholesterol levels. But that hasn't stopped decades of doctors demonizing any food with cholesterol (e.g., eggs) with no actual basis. I know doctors who still give out this crap advice to focus on a "low cholesterol diet" to lower cholesterol. It just doesn't work that way for many (most?) people, and there's no reason it should.

      Now we have a study showing clearly that dietary saturated fat intake does not necessarily relate to the levels that ultimately end up in the bloodstream. Once again, this is common sense -- given that the body PRODUCES fat to store energy. If you're throwing fat into a system that is capable of producing fat, you have to actually consider what causes the system to produce fat... rather than just assuming it's only about how much fat is taken into the system.

      Anyhow, more studies like this will hopefully cause clueless doctors to realize this. Once again, when a system produces the vast majority of X, dietary intake of X is probably not the most important variable -- you need to figure out what regulates the production of X.

      Again, this seems like an intuitively obvious element for isolating what's going on in a system with such characteristics. But it seems beyond the comprehension of medical science -- hence all of the crappy dietary advice with no proven basis.

    The new (more legitimate) demons are trans fats, skewed omega 3/omega 6 fat ratios, and carbs excess

  • So I shouldn't feel too guilty about eating a bagel with a mountain of cream cheese on it. Woohoo!!!

  • Or just another example of how people could continuously claim to know something with certainty all while giving disastrously wrong advice ?

  • This is one study of thousands worldwide that essentially say the same thing. Reduce carbs, increase dietary fat. Over 30 years ago Dr. Atkins began that mantra and well over 30 million people have verified that it works. Atkins followers typically eat more calories than before they began the high-fat lifestyle. It's not just for fat people, diabetics or other sick people- this diet will make most people healthier and live longer. It is difficult to find any measurable health indicator that doesn't improve

    • Actually, it's pretty easy to avoid carbs. When eating in, don't buy them. When eating out, ask for broccoli or asparagus as your side.
  • You really need to read the article to understand the numbers involved here. Don't go on a saturated fat binge.

    There are conditions around increasing the saturated fat intake.

    Inhaling pizza still is not healthy.

  • Obesity, Smoking, Exercise, Genetics, Diet

    Diet is only one small part of the problem
    Genetics - well you're stuck with them - your children are stuck with yours
    Smoking is hard to quit for some
    Exercise - well nobody like to exercise
    Obesity - on the rise - due to sugar, salt, and fat in boxed foods - who cooks from scratch?

    My rant is over

      There have been some studies lately suggesting that genetics are not quite the set-in-stone-for-life thing that we once thought: in fact optimal diet and exercise does improve one's genetics to a small degree. WHICH, has interesting societal implications over the long haul...

  • Nutrition, like education, is fad driven. Whatever we "know" will be displaced in the future for something else.

  • How long will it be before "scientists" say exactly the opposite again?

    I've lived long enough to see everything become unhealthy and then healthy and then unhealthy again. And it's always based "on science".

    The fact is, everything will kill you. That's why I only eat bacon, chocolate ice cream and bourbon whiskey. I may start smoking again, just to be ahead of the curve.

  • I Googled Jeff Volek, the author of the study, and immediately noticed that he is all over the Nutrition Express [nutritionexpress.com] site, which sells nutritional supplements. He also features prominently at True Health Unlimited [truehealthunlimited.com], a commercial personal trining company.

    Good nutrition and personal fitness are good things...but all this commercial involvement makes me wonder just how unbiased Mr. Volek really is.

  • Are they good or bad this week? I keep losing track.

  • Been on this diet for a couple of years now. Works great. I feel awesome and I look awesome, and it doesn't take any real effort. (Though, you have to give blood to keep your iron down, take your magnesium and keep your vitamin C levels up). But if you DO a little training.., wow! Super hero muscles for nothing.

    I don't buy the, "Oh, this time next decade, they'll be telling you the exact opposite!" apathetic complaints. People last decade were fat and unhealthy and heart disease was a problem. All

  • Gary Taubes spelled much of this out (Score:3)

    ...in "Good Calories, Bad Calories".

    Some of it is historical -- prior to the Ancel Keys bad science about diet, it was a commonly held understanding that cutting carbohydrate consumption contributed to weight loss. Taubes cites numerous sources, some dating back hundreds of years. IIRC, even the science was trending this way before WWII but a lot of it was German-led science which the war lost and competitiveness from American scientists chose to bury.

    The science behind insulin as the primary hormonal regulator of fat accumulation has been known since the 1960s.

    Most troubling from Taubes' book is the weird politics of dietary science and how senior people who control funding for studies get wed to particular theories and hang on to them even when evidence doesn't support them, even suppressing promising science that tends to discredit these ideas.
