Studies in nutrition are a meme in themselves. Eating eggs gives you cancer. Next week it protects you from cancer. Coffee cause hearth problems. Next week it prevents heart problems. And so on and on for basically everything we eat.

yeah, I noticed the same thing-- Fad driven science. For some time, Kale was faddy, every study was recommending eating it. REcently, I read somewhere it gives you cancer. groan

I don't know which websites you are using. Respected organization have been providing reliable and non-changing advices for a long time already: https://www.hsph.harvard.edu/nutritionsource/what-should-you-eat/ https://www.hsph.harvard.edu/nutritionsource/what-should-you....

  This advice is extremely vague (on purpose) and doesn't answer any of the more challenging questions, e.g. "What is the full, comprehensive list of specific consumables should I avoid, and the reasons for doing so?"

    "What to avoid?" is a wrong question. The right question is "What to prefer?". And it's answered: https://www.hsph.harvard.edu/nutritionsource/healthy-eating-plate/ https://www.hsph.harvard.edu/nutritionsource/healthy-eating-....

      Answered vaguely and in a way that's incompatible with a lifestyle that doesn't desire daily grocery store trips or eating in places where you don't have complete control over the menu... I'd rather know what to avoid, even if you think that question is "wrong" (I don't agree).

        Have a look at my link: > Skip sugary drinks, limit milk and dairy products to one to two servings per day, and limit juice to a small glass per day. > Limit red meat, and avoid processed meats such as bacon and sausage. > avoid partially hydrogenated oils, which contain unhealthy trans fats. Remember that low-fat does not mean “healthy.”

        Is that it? Is that the full, comprehensive list? If I do these things, am I completely good? I doubt it, and again it's excessively vague: * "Limit"? * "Sugary drinks?" * "One or two servings" that's literally doubling the serving count. How can that be, where consuming twice as many of something is as fine as consuming half? * Juices should be limited but my fruit and veg intake per meal should be 50%, that is contradictory information, unless you're trying to suggest blending things reduces its nutritional value. * If that is the case, how blended? Should I not chop my carrots? Minced onion is worse for me than diced onion, should I just eat the onion whole? * Is it better to starve than to violate these rules? * What, specifically, are the consequences of violating these rules? If I, today, eat one additional serving of fruit than I "ought", am I cutting my lifespan by three days? Six weeks? Even if you can answer every question I put up here, would you mind publishing your phone number so everyone in HN can give you a call every time something isn't covered here? By the way, what are your credentials? Why should I trust your assertion that this is a solved problem, or that your interpretations of this document are accurate? Why should I trust this website in the first place? Yes, it's Harvard, but I don't trust them blindly; how did they arrive at these conclusions? Please, don't condescendingly link to a nutritional chart page and think it answers every question, or suggest this information isn't regularly changing.

I just read the official nutrition advises carefully. And you should too. Also, check the referenced research if you can. > or suggest this information isn't regularly changing.

I don't see any contradiction here. Fruits contain not just sugar but also fiber which is necessary for a good health.

    fried food, sugar, red meat. secondarily, high glycemic index and low fiber, generally not as good as low glycemic index and high fiber. its really simple

I think our intrinsic reluctance to fully consider genetic differences among populations is a massive confounder in nutritional (and medical) science. Modern human populations are far more genetically distinct than we are allowed to acknowledge. It's a deeply seated bias that pervades medical and social sciences and is the root of so many conflicting results.

nothing is true, you cant trust anyone, professors are all acivists, BLM burned the cities down, the fed is just printing money. bitcoin - the best money we've ever had, deserves the best credit card we ever had.
