- OrwellianChild 11y agoLots of well-researched, clearly explained science here. He doesn't shy away from the terminology (randomized, controlled trials, etc.) but also offers a more accessible breakdown of the implications of research...
- smtddr 11y agoThis is the most important part of the article: >>"We know much less for sure than we think, and recommendations that forcefully tell people exactly what and precisely how much they should or should not eat can be counterproductive." Unless you have a very acute and well defined health issue like diabetes or severe allergy, people who try to sell you on diet-absolutes are full of nonsense or trying to sell a product.
- chillwaves 11y agoThen why are we facing society wide epidemics with Diabetes type 2? Certainly there must be some change in the way we live and eat that is responsible, that could be corrected. Your argument leaves no room for such a correction.
- OrwellianChild 11y agoAll the parent called out was that we don't know enough about diet and its health impacts to make a definitive declaration about good/bad foods. He even called out diabetes as an exception, since it is better understood... We need to do more research and learn more before demonizing things like fatty foods. That's all. Not sure what part of this you object to...
- Mz 11y agoYou might be interested in looking for articles on "diabetes and inflammation" and then "inflammation and infection." There is a connection between diabetes and inflammation. Inflammation can be caused by infection and can also promote infection. We don't know why there is so much diabetes. It's possible it involves infection, something that will not be entirely solved by diet alone.

- Mz 11y agoMy view is strongly influenced by the fact that I have "atypical cystic fibrosis." Cystic Fibrosis predisposes people to CFRD (Cystic Fibrosis Related Diabetes). My understanding is that this form of diabetes is neither Type 1 nor Type 2. CF is a genetic disorder. With CF, your immune system does not work right and you are basically chronically infected with some infection or other. I have a relatively mild form of it, which helped create a situation where I was diagnosed late in life. I finally got diagnosed due to my health deteriorating drastically and I spent a year at death's door. With finally getting a diagnosis, I was empowered to get myself a great deal healthier. I have fewer blood sugar issues than I used to have. I did nothing to specifically address that issue. I was primarily trying to erradicate the antibiotic resistant infections that were threatening to kill me. People with CF misprocess fats and most of them are seriously underweight. To my mind, this suggests that fat is probably not the real culprit with diabetes. I have become very picky about the types of fats I eat. Butter and coconut oil are fats that are very beneficial to my condition. I sometimes get pain under control by spreading a half a stick of butter on a roll and eating that (or did so at one time -- it has been a while as my condition is more stable). Butter and coconut oil are high in saturated fats. My blood sugar is a great deal more stable than it used to be. (Yes, I know that is "anecdotal." If you want to dismiss it, please come up with a stronger criticism than that. Thanks.)
- personomas 11y agoAbsolutely, too much cocaine is unhealthy. Absolutely, too much heroin is unhealthy. Absolutely, too much sodium, sugar, etc etc is unhealthy, and this absolutely not nonsense. However, we can agree that there are many people who give diet-absolutes advice and are totally wrong. But there is good advice out there too, and we shouldn't close down assuming all advice is bad advice, just because some it is bad advice.
- travisp 11y ago> Absolutely, too much sodium, sugar, etc etc is unhealthy, and this absolutely not nonsense. But "too much is unhealthy" is a tautology. There are a number of studies that show that sodium-restricted diets may increase all-cause mortality. So "too much sodium...is unhealthy" is not nonsense but completely meaningless and unhelpful as advice. We generally know much less about nutrition than is commonly portrayed.
- AnimalMuppet 11y ago> But "too much" is a totality. There are a number of studies that show that sodium-restricted diets may increase all-cause mortality. So "too much sodium...is unhealthy" is not nonsense but completely meaningless and unhelpful as advice. You seem to be arguing that, because too little is harmful, saying that too much is harmful is meaningless. That seems... less than logically sound. Or have I misunderstood you?
- travisp 11y agoYou may have been misled by my autocorrect. I meant "tautology" not "totality". Saying that "too much" is bad for you will always be true because by definition "too much" is more than you should have. The problem is that, in nutrition, we usually don't know how much is too much (outside of absurd levels that aren't commonly reached). We know that reducing sodium may be harmful. It's possible that attempting to reduce sodium below what the average person consumes may be harmful (or may be harmful for some portion of the population). We don't know what is the "ideal" level or range of sodium. So, yes, it is true that "too much" sodium is bad for you, but we don't really know how much is too much, or even if the amounts that people eat today are actually too much for the typical person.
- pasbesoin 11y agoEven with diabetes... Although this is not strictly a "diet" issue, for years, many doctors tried to strictly control blood sugar levels in their patients. Variations were frowned up. Turns out, research has now shown that such "overmanaged" patients actually fare worse than those who allow some flexibility in glucose levels. I have a quite knowledgeable family member who has diabetes, from whom I've learned this. As I've gotten older, I've watched a lot of... um, "best practices", in health care as in other matters, be debunked. And, in retrospect, the advice often was a matter of self-reinforcing opinion rather than demonstrated science and research results.
- AnimalMuppet 11y agoA doctor friend of mine said, "Half of what we [doctors/medicine] know is wrong. Unfortunately, we don't know which half."
- Retric 11y agoI really question how controlled these diets where. It's one thing to keep someone in a controlled environment select specific foods, but suggestions to eat in a specific way for long periods of time seem largely untenable.
- eric_h 11y agoPerhaps, but accompanied with a food diary, you can at least account for what a person's diet actually consisted of (even if they didn't follow the guidelines/suggestions to a T)
- frofroggy 11y agoSuggestions to eat in a specific way for long periods of time seem even more untenable when the predominant way of meeting the guidelines is manual guess-and-check, and at worst guess-and-check-and-ignore.
- jimrandomh 11y ago> The committee concluded that existing reports argue that replacing saturated fats with polyunsaturated fats seems to reduce the risk of cardiovascular events and mortality. "Polyunsaturated fat" is a bad category; it includes both omega-3 (generally considered good), omega-6 (generally considered bad), and omega-9 (generally neutral). Statements about polyunsaturated fat which fail to distinguish these have no possible hope of being correct.
- bad_user 11y agoExcept that this is reductionist science at its best. There's not enough evidence to conclude that omega-6 is considered bad for our health. What may be important is the balance between omega-3 and omega-6 in one's diet, with omega-6 ending up having negative consequences when one ingests too much simply because those same people aren't ingesting enough foods with omega-3. Basically when speaking of food, humans have a finite capacity to eat, so if you eat too much of something, then you eat less of something else. This may be the case for vegetables versus meat. It's generally accepted that too much meat is bad for our health, but the cause is completely unknown. And it's certainly not the fats, as we've been led to believe. Eating too much meat may be unhealthy simply because those people aren't eating enough vegetables. Want to bet that in 4-5 years tops the current beliefs with those fatty acids will be turned on its head? There's no science that has failed us more than nutritional science. Pick any cult, any religions, any of the superstitions that have survived for hundreds or thousands of years and you've got something healthier than nutritional science because people have survived those cults and superstitions, yet it's becoming clear that nutritional science is responsible for the obesity epidemics ;-)
- CuriouslyC 11y agoPlease don't propagate the "omega-6 fats are bad" myth. Meta analyses of many studies done on linoleic acid intake and inflammatory biomarkers show that they aren't pro-inflammatory in humans (the most common issue food bloggers raise) and they have been shown to be a strong negative risk factor for heart disease in epidemiological studies. With that being said, refined oils high in omega-6 fats should be avoided, as all the anti-oxidants that keep them from going rancid in their whole food form are absent.
- the_watcher 11y agoThe frustrating part of these articles is how they tend to ignore that diet and exercise are intrinsically linked. Live a sedentary lifestyle? Limiting fat (and general caloric intake) is the right move. Work out intensively for an hour daily? You almost certainly aren't consuming enough fats.
- OrwellianChild 11y agoWell, there's additional nuance here... Caloric intake is made up of 3 principle inputs: carbohydrates, fat, and protein. The recommended daily allowance of each is in balance, so if you eat fewer carbs, you have to eat more fat or protein to reach your caloric intake. U.S. governmental regulations have long discouraged fat intake, replacing those calories largely with carbs. This was based on the assumption that the fats were harmful, rather than extra calories in general. The article is highlighting a change in understanding that will hopefully have us stop demonizing fats in favor of carbs in a diet that is otherwise within bounds calorically. In short, we know now that it is not necessarily bad to eat fats (anymore than it's bad to over-eat in general).
- the_watcher 11y ago> Why Butter, Meat and Cheese Belong in a Healthy Diet I sometimes feel like at least a third of the resistance to ideas like fat is ok is based in a deep-rooted belief drilled into us by fad diets that eating healthy can't also be delicious.
- atomical 11y agoI think that modern fad diets tell us that our bad habits are good. Who doesn't want to be told that they should eat cheese, bacon, and steak all day long?
- mobiuscog 11y agoBut they're only 'bad' habits because previous fad diets told us that.
- atomical 11y agoDietary cholesterol is bad for you.
- the_watcher 11y agoLiterally no evidence to support that.
- atomical 11y agohttp://nutritionfacts.org/video/egg-cholesterol-in-the-diet/ http://nutritionfacts.org/video/egg-cholesterol-in-the-diet/ Literally? Or imaginatively?
- bitL 11y agoSome vitamins (A, D, E, K) are fat-soluble, so good luck not eating any fat and significantly increasing your risk of getting cancer. A lot of people have problems absorbing vitamin D from food on their own; helping them even more with low-fat food is wonderful /s. Also, milk from properly fed cows contains conjugated linoleic acid (CLA), aka Tonalin, which helps weight loss, despite being a kind of trans-fat, which we all know is dangerous /s. I am always puzzled while in the States that I can't buy anything non-low fat and barely a single brand of unsweetened yogurt even in Whole Foods; it feels like I am forced to buy only inferior food over there, guys. I then imagine your food industry extracting most of beneficial fat from milk products and selling you supplements containing those ingredients for significantly higher price...
- hga 11y agoThis yougurt has varieties made with whole milk, look for the red rings: http://www.oikosyogurt.com/greek-yogurt/ http://www.oikosyogurt.com/greek-yogurt/ It's available in e.g. Wal-Marts in flyover country, and it tastes very good. Lots of sugar, of course, but also the fat. I think I recall some unsweetened yogurt, but non-fat, so it's like the descriptions I like of 1 and 2% milk: the first is water with one white crayon briefly dipped into it, the 2nd gets two crayons ^_^. But whole milk is plenty available. Hmmm, over here isn't not hard to buy stuff with "healthy" amounts of fat, but, yeah, sugar abounds. Ah, but the bacon counterrevolution is a wonderful thing ... although my favorite is Oscar Meyer, which is "sugar cured"; well, after salt, and officially ends up with 0 carbohydrates (i.e. below the reporting threshold). So not all is lost!
- astrange 11y agoMost yogurt brands have unsweetened yogurt, but it's off to the side, only comes in very large sizes and is just plain yogurt. The usual cycle of Greek yogurt is that new high-end brands appear with no sugar, get popular, then introduce new flavors filled with sugar. Some of them hide it in the ingredients list by calling it "evaporated cane juice", as if you didn't know what kind of cane they were talking about.
- gorena 11y ago> barely a single brand of unsweetened yogurt even in Whole Foods Huh? My Whole Foods has Fage (the best, IMO), Siggi's, Wallaby, and more.

- tracker1 11y agoAveraging your intake over the course of a week.. try to get 60-100g protein per day (can get more if trying to build lean muscle, that's a minimum for most). Stay under 100g sugars, and try to keep a total glycemic load under 100/day. Keep your daily calorie average appropriate for your desired lean body weight. Try to get 5% more activity in each week, unless you are at a maintenance point. Get a variety of foods (fruits, vegetables, meats, etc), and avoid what causes you problems with digestion... That's hard enough without going into too many specifics and would generally serve people better in general. Once you get your needed protein in, for the most part, calories are a wash... excessive sugars/carbs causes other problems over time. But trying to say you can have X and not Y is a path to failure for most. Also, trying to keep it on a daily basis doesn't always work so well either... if I get a few days a week that I have a longer fast cycle (eating once a day), I tend to do better... But it's a matter of keeping your overall intake in relative check without dwelling on any particular piece. Eat food, avoid processed foods, eat veggies and fruits, get a variety, don't eat too much... it's not all that hard, but that's not how people think... we've also got generations of snacking, sugary drinks, and carb/sugar laden food supplies.
