>Hasn’t it been proven many times that fruits are healthy, period?
Fruits are healthy in the same sense that dihydrogen monoxide is. Infinitesimal amounts have no health consequence, moderate amounts are healthy, amounts that exclude other foods will cause nutritional deficiencies, and excessive enough amounts will result in suffocation.
Sure, but if you eat a kilo of apples a day you'll get sick of apples and eat a light lunch worth of calories. Eat a kilo of chocolate and you're eating double your daily calories. Nobody got obese because of their 10kg-a-day apple habit.
