Humans are hardwired to love sugar. We know that too much of it is bad for us—but it’s hard to argue with our brains, which consume a fifth of our daily calories and wants them in glucose form.

And since everyday foods like yogurt, peanut butter, and tomato sauce contain sneaky added sugars, it’s hard not to get hooked.
