Fruit has a lot of sugar in it, too. Do you avoid fruit as well?
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...
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.
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.
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)

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."
Bananas and dates are the main exceptions to this.
... 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.
