So one orange, a large apple and a banana per day will hurt my liver (totaling 63 grams of sugar[1])? Where is the scientific evidence supporting this? [1] http://www.sugarstacks.com/fruits.htm

The recommendation is about added sugars, which means sugars that are processed to remove all the fiber and everything else. Fruit is not added sugar.

I thought the fiber was good because it made you feel fuller and you don't eat as much, not that you somehow interacted with sugar to "disable" it. What's the connection?

>Too much of everything is always bad. That's folk-wisdom, which is sort of a good heuristic but is not useful when we can actually test and demonstrate. Some things are bad even in small quantities, say poison. Somethings we can't get enough of, say fresh air. I've mostly cut out fructose (and most other forms of sugar) altogether from my diet and it's probably the single-most impactful change that I've made in my l…

> Somethings we can't get enough of, say fresh air. Well, if you get too much air, the pressure will probably kill you, so... ¯\_(ツ)_/¯

Even at ~atmospheric pressure, it depends on where you put it.

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.

Yes, and rape seed oil has the about the same combination of fatty acids as olive oil; which is healthy; but it's still poisonous gmo crap. Same goes for HFCS. The amount of genetic manipulation, processing and refining matters.

Hm, did you read my comment? I said source: Wheat Belly (book by Dr William Davis), but also my experience working with clients and with trainers who are experts at transforming clients from fat to fit.

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.

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

Whole grains are one of the biggest sources of dietary inflammation. There isn’t something inherently wrong with grains, it’s that they’re not even close to the grains we evolved to eat anymore (at least, not in the U.S. — grains in mainland Europe are generally fine, unless you have an issue with gluten/grains such as celiacs, Crohns, or IBS). Source: Tons but the book Wheat Belly is one of the most succinct. Also,…

Dr. John McDougall refutes the arguments that whole grains are unhealthy and cause disease in his critique of Wheat Belly.

Sounds like Lustig's holy war on fructose again. Show me on an animal model how fructose is linked to hepatosteatosis and we'll start from there.

Until then, I'm just going to remember how Lustig's main argument for fructose being a toxin was that it's metabolised in the liver.

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?

My guess would be nuts, vegetables, and meats (like fish). Some fruits are okay though, like low sugar ones (avocados). I personally have tested my diet for years and found this diet to be optimal for me, and in line with most current research on what the body needs—and what the body should stay away from.

Many people would consider a diet like this difficult, but if you approach it correctly (I end up cooking a lot of szechuan cuisine), it's quite easy—and delicious!

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!

There's nothing wrong with whole grains or fruit. The book "Wheat Belly" is terrible science.

Also, my wife is a registered dietitian with a PhD, not a "nutritionist".

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.
