As far as I'm concerned, fruit is the same thing as eating gummie bears. The only difference is that fruits have a minute amount of fiber and micro-nutrients. But if you want actual useful amounts, you'd better be eating vegetables of various kinds and organ meats.
Regardless of the potential health risk of sugars, the whole "fruits are good for you and you should eat a lot of them" is complete crap in my (uneducated) opinion.
Here's how easily falsifiable your shitty hypothesis is:
One cup of gummi bears vs. the caloric equivalent of apples (six apples! Just to give you some perspective on density, satiety, water, and digestion).
The gummi bears come in at:
547 calories
23g of water
9% RDA Vit C
25% RDA Copper
9% RDA Selenium
8.5g protein
The equivalent calories from apples comes in at:
565 calories
943g of water
69% RDA of fiber (26g)
3g protein
15% B1
25% B2
6% Niacin (B3)
13% B5
34% B6
20% Vitamin K1
13% Vitamin E
20% Vitamin A
65% Vitamin C
7% Calcium
33% Copper
15% Magnesium
16% Iron
17% Manganese
25% Potassium (this is huge)
17% Phosphorous
8% Folate
And this is me picking a single fruit, and a not even a great one, nutritionally, at that. If I mixed in a combination of fruits that matched the ~550 calories of gummi bears, the difference in nutrients would be staggering. Using a mixture of 1 medium apple, 1 medium banana, 1 cup of orange juice, 1 cup of mixed berries, half a mango, and half a pear, it increases the overall nutrient count by 50-100% compared to the apples I used above.
Fruits are good for you, and along with dairy consumption, are one of the few defining differences in the composition of diets when comparing lean and obese populations. Yes, vegetables and organ meats are nutrient dense in comparison, but they don't taste nearly as fucking good, aren't nearly as accessible, and require way more preparation to taste their best.
And carbohydrates are useful as fuck, considering they provide energy that is required to provide your most metabolically active systems - namely the brain, heart, kidneys, active muscle, and digestive system - with their ideal substrates (glucose, fructose, lactate). And there ain't nothing wrong getting those carbs from fruit.
