There was a story about this in the NYT recently (can't find it) and IIRC, it basically said protein is out and fiber is in. It wasn't that simple, but that was my takeaway.
Just because an article comes from Harvard doesn't mean it's correct -- Harvard scientists were also behind the original food pyramid, and were likely paid off by the sugar industry.
If you're on a low-carb diet you should supplement fiber.
Tangent, but it reminds me of how people consider a "balanced" diet to be 1/3rd protein, 1/3rd fat, 1/3rd carbs. It sounds good, until you consider the purpose of carbs. Carb's aren't inherently bad of course, but they have glucose which stimulates an insulin response, resulting in storing more food as fat. And considering how many obese people we have, the "balanced" diet seems to be very unbalanced. The thing with carbs is, you really only need to take them in if you're very actively doing anaerobic exercise. If you're doing that, great! Then you should eat carbs. If you're sitting at a desk 8 hours a day and not exercising at all, then you really don't need much in the way of carbs at all.
Higher fiber seems, at best, to not move the needle much at all. At worst you could irritate various gut linings. Fiber in things like fruit can be good because it moderates the absorption of fructose, but I generally don't think you need to supplement fiber at all.
Turns out just slowing down digestion can have a lot of benefits.
Also, most Americans eat very, very little fiber. Anything is an improvement. I believe the FDA recommendation is 30 grams a day, and most Americans eat, like, 2.
However, most Americans are not deficient in protein. They eat lots of meat, and very little veggies.
I agree people should eat less carbs in general, but we need to be careful. Ultimately, replacing kale or something with bacon, which is basically tobacco in meat form, isn't going to improve their health. Eat less carbs, eat more protein, but eat the right protein, and the right carbs.
I sometimes wonder if the complexity of the human body doesn't stop us from seeing things that can have great positive effect on a set of people because it's counteracted by the effect on another set of people so the result in the whole is cancelled out. I now wonder if the statistic methods used in these studies take this into account.
All this to say that I approve of controlled self-experimentation, but you need to be very rigorous and brutally honest. Most people are not.
A glass of water with psylium husk a day and you solve a lot of modern diet problems.its also super cheap,a $20 bag can last you a year.
The entire problem is that most people in high- and middle-income countries are in fact doing something blatantly wrong - they are consistently eating vastly more calories than they use. Some of those people are ignorant of what 2000 to 2500 calories actually looks like, some are deluded, but a very large proportion know damned well that they're eating far too much and do it anyway.
The obesogenic environment that we now live in is partly due to the influence of the processed foods industry, but in large part it's simply a product of abundance. Before the late 20th century, it was simply inconceivable that poor people could afford to become morbidly obese. Agricultural productivity has improved beyond all recognition and the world is flooded with incredibly cheap food of all kinds.
We've spent the last few decades trying to push back against that with all manner of initiatives intended to endgender behavioural change, with very little success. It doesn't really matter what guidance we give people when they have shown a consistent inability or unwillingness to follow it.
If we're actually serious about the effects of diet on public health, I think there are only two credible options - extremely heavy-handed regulation, or the mass prescribing of GLP-1 receptor agonists. All of the other options are just permutations of "let's do more of the thing that hasn't worked".
but it's tricky to figure out and i assume the consensus rules are good enough for most people
Google tells me that 2 lbs of steak contains between 225 and 270 grams of protein. That would be well over the threshold that the article I linked to a couple of posts up mentions:
> Your kidneys process all the extra nitrogen from the protein, and when you’re eating 200 grams a day, sometimes they just can’t keep up and they get stressed.
