Just wanna say that my wife has a PhD in nutrition and this isn't news to us. We've "known" that unbound fructose is hard on the liver for years.

what do you and your wife eat?

Everything except red meat and dairy, honestly.

But if you want to know what we believe to be true about which foods are healthy, there's probably no better starting point than Harvard's Healthy Eating Plate.

The main title in the article ("The Toxic Truth") is a tribute to UCSF's famous Dr. Lustig of the lecture "Sugar: The Bitter Truth" [1], which is a fascinating and well worthwhile lecture about the biochemistry of fructose as it relates to obesity. I thought I'd just watch a few minutes of it and ended up sitting through it and learning a whole lot.

He also wrote a book on the topic("Fat Chance: Beating the Odds Against Sugar, Processed Food, Obesity, and Disease")[2].

Fun fact for HFCS bashers: it’s nearly the same blend of sugars as honey. If you think HFCS is bad (and I believe it is), honey can’t be good.

Honey has micronutrients HFCS doesn't have. But by far the biggest difference is price. You won't overeat honey simply because you won't want to pay 21 times more. And for a taste that is not a direct replacement of sugar and may not combine well with everything.

The amount of micronutrients in honey is inconsequential, it is measured in single digit milligrams per hundred grams. It consists primarily of sugars and water, and the main component is fructose.

Your wife is one of the few pedigreed nutrionists who “knows” that! Sadly most nutritionists are overweight themselves and continue to advocate people consume whole grains, low-fat dairy, and fruit to lose weight/be healthier. Kudos to your wife for ignoring the massive amount of BS most doctors and nutritionists are inculcated with!

You misinterpreted what the parent said. Whole grains and fruits are not unbound fructose.

Does she recommend low fat food alternatives to her patients? My nutritionist pushed them like the gospel. And she would tell us in the next sentence that most low fat foods had added sugar to increase the flavor.

Citations, not a diet books and anecdotes. Edit: hate my tone all you like, but keep in mind if this weren’t fringe bullshit I’d be met with more than downvotes and attitude.

The aversion to new facts is palpable. This is the top google hit to “wheat dietary inflammation”: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3705319/ But really, your problem is not that the GP did not cite their facts, you just don’t like the sound of their claims, so you’ll respond in a toxic way. I hardly expect the actual scientific literature to change your views.

My problem seems to be that there is some significant overlap between the groups, “people who use HN” and “people who are the target audience for self help books.” Worse, are people who can’t cite and instead throw articles into the mix, while being condescending and pseudo-psychic.

Just bury me in good citations and we can both be happy.

Congrats! Yes that’s also true. But cutting grains also fixes your sense of satiety. Ever had a piece of bread and then next thing you knew the whole bread basket was gone? Many people feel like they can’t control themselves when eating bread. No one does that with steak. And even other high-carb foods like potatoes present less of a problem for people (in terms of whether they feel full and stop eating vs continuing…

I don't think it's grains in particular that mess with satiety - it's carbohydrate-heavy diets (particularly simple carbohydrates) vs protein/fats. Protein in particular is known to be highly satisfying, and it tends to be less calorie-dense than carb-heavy foods. Carb-heavy foods are everywhere, because they prepare easily and keep for a very long time, and provide a lot of calories in a small package. Sugar + fat t…

No citation available, but I see far more people drinking fruit juice than I do eating fruit with the skin/fibre still intact.

Fruit juice is no better than soda pop.

At least fruit juice has some nutritional value. You're right though that it still isn't a "healthy" choice.

What is wrong with whole grains or fruit? I have never heard of that before.

Nothing, I think the parent is wrong or misspoke. The advice is usually "substitute bad processed sugar with fruit", which is what Dr Lustig has advocated for the last decade. Of course too much fruit is itself bad, since the fiber can only do so much.

Why would too much fruit be bad? This is sadly a myth that gets formed when “sugar is bad” is oversimplified.
