Healthier but not necessarily far healthier. It's harder to overeat fruit since much of it has large water and fiber content. But fruit is still mostly empty calorie sugar. When given the choice between junk food and fruit pick fruit but there are alternatives.

>sugar is far healthier than sugar

Really? By what definition of "healthy"?

Fruit contains far more than just sugar: fiber for example, is great for you. Vitamins and minerals are also, generally speaking, good for you.

Furthermore, eating fruit will not spike your blood sugar the same way an equivalent amount of pure sugar or a caloric equivalent amount of junk food.

These are not controversial statements, there is plenty of actual research to back this up.

Finally, there are many ways to heat healthfully, and fruit is not essential: however it is unambiguously healthier for you than junk food.

Yes, eating fruit will spike your blood sugar just like candy will. Notice how diabetics need to eat candy or fruit if their blood sugar gets low? There's a reason they say either one, because they have the same effect. Sugar is sugar. You believe adding a tiny amount of a few vitamins that are easy to get well over your RDA of already makes candy into health food. I believe candy is still candy even with a bit of vitamin C in it.
