By now you’ve gotten the memo that cutting back on sugar is one of the best things you can do for your health. It’s something even the most ardently opposed diet gurus agree on, and it was one of the big take-home messages in the new Dietary Guidelines for Americans released in January.
Beyond adding empty calories and spiking blood glucose, which can contribute to weight gain and the myriad associated health issues, eating sugar dramatically increases your risk of dying from a heart attack. A major study published in JAMA Internal Medicine in 2014 found that people who ate close to 20 percent of their daily calories from added sugar had a whopping 38 percent higher risk of dying from heart disease than those who ate half as much. (To be clear, I am talking about added, refined sugar here – the concentrated sweetener put into foods, as opposed to the sugars inherent in whole fruits and dairy. Because those foods are naturally “packaged” with water, fiber and other nutrients, they do not have the same negative effect on your health. In fact, most of us should be eating more of them.)
Okay already. You are convinced that you need to cut back on added sweeteners; you may have even made it your New Year’s resolution. But if you have discovered that sugar has an unexpected hold on you and you can’t seem to resist it, you are not alone, and it is not necessarily about a lack of willpower. The game is rigged in sugar’s favor for three main reasons: We are born to like it, it is everywhere, and it is addictive.
Humans have an inborn preference for sweet. We taste sugar and our pleasure sensors fire like crazy. When our ancestors were running around in loincloths, that genetic predisposition helped them survive, as sweet foods provided a valuable source of energy and were less likely to be poisonous than bitter foods. Concentrated sources of sugar, such as wild honey, were a rare find and tough to get (and it meant facing a hive full of bees).
