1. Fruit is not healthy in large quantities. (Everything in moderation?)
2. If you eat fruit in its natural form (with the fiber etc), it has a much lower glycemic index than processed. Also consider the glycemic index and load of an apple is much lower than a potato.
Its worth noting that in the form of something like a smoothy, a person can consume more fruit than would be possible eating actual fruit. Imagine a counter top of fruit turning into a single large smoothy...
Fruit is perfectly healthy in large quantities if it is raw with nothing added. The human body is very capable of processing the sugars in fruit.
It's when those sugars get extracted and concentrated we run into trouble. Juices and smoothies are more dangerous because they concentrate the sugars while removing fiber. This decreases the liver's ability to process the sugar. But actual refined sugar is most dangerous.
You should check out Dr. Lustig's youtube videos and his papers. He cites plenty of evidence. He also explains the mechanism by which fructose is processed by the liver, and why the fructose in fruits does not cause problems.
In its natural form sugar is not singled out and thus other molecules from the fruit influence its absorption. For example, vitamin C in its oxidized form is transported by the same receptors as glucose (GLUT4) and quercetin is very good inhibitor of glucose transport.
I still doubt tho, that high quantities of fruit are good for you. One of the reasons is that current forms of fruit we eat are selected toward sweater taste.
I've read a few papers that suggest our bodies absorb sugars differently in the presence of other chemicals that are present in the fruits themselves, but not in the processed versions? I think this is one of those papers?
This is all on a continuum, I would concur that large quantities of raw fruit is far better for you than the same payload in say Coca Cola.
But is stands that it is possible to become insulin resistant from eating raw fruit, and this is simply not possible from eating eggs for example.
In regards to insulin resistance there is an upper bounds of healthy fruit consumption, just there is with almost any food (although for some foods the consideration may bot be blood sugar, but rather be total calories or omega-6 poly-fat, etc)
That is very unlikely, show me some real science (not the one flawed study from a few years ago). Type II diabetes is severe insulin resistance. A food like eggs don't have sugar, your body doesn't produce insulin when you eat them, therefore its not possible through any known mechanism for them to contribute to type II diabetes.
This is true. But non carbs have a much lower insulin response.
>A steak produces as much insulin as pure sugar.
Are you saying grams of protein to grams of sugar? A steak has a smaller insulin response than a piece of bread, not only that, the shape of the spike is drastically different.
"Recent research has shown that moderate egg consumption—up to one a day—does not increase heart disease risk in healthy individuals (1, 2) and can be part of a healthy diet."
Actually, most fruit is fine even in pretty darn large quantities, due to the fact that the sugar is absorbed slowly, and it is paired with phytonutrients that have anti-oxidant and anti-inflammatory properties.
Bananas and dates are the main exceptions to this.
Fruit does not have added sugar and the fiber in fruit helps slow the digestion of the fructose greatly dampening the negative effects of the sugar. Plus fruit is loaded with naturally occurring vitamins essential to the human body.
It actually is. Except it's not added between growing and fruit and consuming it, but before growing the fruit. Fruit have been bred and genetically engineered for high sugar content for millennia.
... none of this is to bash fruit - they are definitely a much better alternative to sugary drinks and even fruit juices, due to their low glycemic load. But still, it's important to remember that fruit, especially some fruit, are far from being sugar free.
That statement seems to draw a narrow definition of "fruit". Olives have no sugar. Tomatoes and cucumbers have very little. All three are fruits and good staples in any diet.
