Nutritional guidelines have very short lives compared to every other field of science. It's such a minefield of contradictions. Astonished how many pretend a topic so complicated by biology/genetics and routinely proven wrong can be easily broken down into simplistic good/bad buckets (and of course they definitely got it right this time) Saturated fats and salt are next in line to fall, despite how hard the entrenched old guard of health authorities want to ignore the new evidence.

>Nutritional guidelines have very short lives compared to every other field of science. It's such a minefield of contradictions. Like psychology. And I'm sure there are many other examples.

  Nutritional science seems worse, but I think that's because real (not pop) psychologists seem to be giving up on simple good/bad and fad advice. There is so much of this in nutrition because there is profit motive via the food industry.

    Drugs are another industry. We will look back at SSRIs and benzos the same way we look at lobotomy now.

      Only when we have much better things of course. Progress is being made. The thing about nutritional science is that progress seems like it's just not being made at all. We go from fad to fad.

IMO the next change might be general promotion of vitamin and essential fatty acid supplements (notably linseeds or linseed oil).

First it was fat, so we got low fat products and the sugar replaced it. Now sugar is the enemy, so low carb high fat (Keto). Next will be protein.

  Put fat and sugar together and you get very palatable foods (like ice cream). It makes sense that removing either would help control weight.

  Protein already came and passed. That's why cereal breakfast was introduced to avoid proteins in the early 1900s. Ironically the man behind the campaign against protein was called Dr Kellogs and you can guess which company he founded. There's a great documentary called In Defence of Food. Check it out.

Diet studies are some of the most corrupt in American science, given the huge amount of money at stake based on what the American public eats. It’s not unusual to discover that the academic who releases a study proclaiming the magical power of <Food Group> is actually receiving money from the <Food Group> association.

Lifestyles and activity levels have dramatically changed. Eating breakfast everyday and consuming high levels of carbohydrates is actually a good idea, if you do manual labor on a farm. Western lifestyles are relatively sedentary, yet our brains are consuming more information than ever. Mental processes have nutritional needs and we're stabbing in the dark as to how to approach this problem. People have not figured out the best regimen for this new lifestyle.
