Why We Get Fat

What makes fruit worrisome from the perspective of Adiposity 101 is that it is sweet to the taste precisely because it contains a type of sugar known as fructose, and fructose is uniquely fattening as carbohydrates go. As nutritionists and public-health authorities have become increasingly desperate in their attempts to rein in the obesity epidemic, they’ve also become increasingly strident in their suggestions that we eat copious fruit along with green vegetables. Fruit doesn’t have to be processed before we eat it: it’s fat- and cholesterol-free; it has vitamins (vitamin C in particular) and antioxidants; and so, by this logic, it must be good for us. Maybe so. But if we’re predisposed to put on fat, it’s a good bet that most fruit will make the problem worse, not better.
