Let’s get one thing out of the way right at the start: there is nosweetener that we can consume vast amounts of with impunity. None. There are certainly some that are better than others. There are some that even have side benefits. But the take-home message is still “eat sweets in moderation, if you eat them at all.”
Easier said than done, of course. Sweets just taste so good. There’s a reason for this. We crave sweets, like we crave fat and salt, because the taste represented a scarce and valuable commodity to our ancestors. And since, thousands of years ago, our ancestors hardly ran the risk of getting too much of these things, our taste buds and our brains were programmed to seek out as much as we could get.
