Sugar out of sight is also out of mind

Here’s a shocker: the average person takes in 22 teaspoons of sugar daily—more than three times the amount suggested by the American Heart Association. And although it has never been considered a health food, new evidence shows sugar can do even more damage than previously thought, setting you up for obesity, diabetes, and heart disease. But weaning yourself off sugar can be daunting. It’s tough to dodge because it hides in so many foods, and it provides an almost addictive buzz, thanks to a surge of the neurotransmitter dopamine after it enters the body, says research neuroscientist Nicole Avena, PhD, author of Why Diets Fail (Because You’re Addicted to Sugar) ($19; amazon.com). Still, slashing sugar is one food trend worth trying. Find out all about sugar rehab, plus tactics to make your commitment stick.
The dangers of sweet stuff
Sugar has 16 calories per teaspoon. That doesn’t seem like much, but it can pack on hundreds of calories without offering any nutritional value, says Avena. Extra calories raise your risk of obesity, which in turn sets you up for diabetes.
A 2013 study found that for every 150 calories of added sugar consumed in a population—the equivalent of one can of soda—diabetes prevalence in the population went up 1.1%. Then there’s the research tying sugar to heart disease. A 2014 study from JAMA: Internal Medicine found that the more added sugar a person took in, the higher their odds of dying of heart disease.
Don’t forget about the way sugar plays with blood glucose levels, sending them surging, then crashing—leaving you fatigued, brain fogged, and irritable, says Brittany Kohn, RD, a New York City nutritionist.
Cut this kind of sugar
The sugar offender to steer clear of is refined white sugar, the kind spooned into coffee or added to baked goods. The bloodstream absorbs this simple sugar quickly, causing surges in blood glucose levels and insulin that can wreak havoc on the body, says Avena.
Refined sugar is also added to countless food products during processing, from ketchup to bread to salad dressing to beef jerky. Manufacturers try to trick consumers by calling it cane sugar, high fructose corn syrup, or some other unfamiliar name, but they’re all just fancy ways of saying sugar. Molasses, honey, and maple syrup are also added sugars, and though they’re not always processed the way refined white sugar is, they have the same harmful effect, says Avena.
Sweets you can eat
The types of sugar you don’t have to ditch are found naturally in foods, such as fructose in fruit and lactose in milk products. These get a pass as long as you consume them in their original food form. “Fruit, for instance, contains an amount of sugar that is in better proportion with the amount of fiber and other nutrients in it,” says Aveda. “These other nutrients mitigate sugar’s harmful effect.”
Artificial isn’t the answer
Swapping out sugar in favor of a chemical sweetener like aspartame or saccharin may not be the answer. “Artificial sweeteners provide sweet taste without calories, so when you consume these products, hunger isn’t satisfied, leading you to crave more afterward,” says Kohn. A 2013 study in Trends in Endocrinology & Metabolism lends credence to this, finding that drinking just one diet soda a day is linked to weight gain and diabetes.
Why do chemical sweeteners boost hunger? It’s not clear, but it might have to do with the intensity of the sweetness in these products. Artificial sweeteners are many times sweeter than natural sugar, and that can dull your taste buds to less intensely sweet foods such as fruit, ramping up cravings for high-sugar—and high-calorie—foods, says Kohn.
Don’t go cold turkey
Because our bodies are so used to the sweet stuff, going sugar-free very abruptly can lead to crazy-intense withdrawal symptoms such as headaches, anxiety, and mood swings, says Kohn. Ever gone without your usual morning latte or other caffeine fix? That’s what sugar withdrawal is like, times 10. “It’s better to ease yourself off it slowly by taking one step at a time, so your body has time to adjust,” says Kohn. Another reason to not be in a rush: slower changes tend to last, says Avena, especially when it comes to diet changes.
Give up sugary drinks
Soda, fruit juice, sports drinks, iced tea—these and other sweetened beverages are sneaky sources of added sugar. One can of cola, for example, racks up nine teaspoons, already a third more than the six teaspoon daily limit suggested by the American Heart Association.
“Sweetened beverages or drinks made from fruit juice are like liquid sugar, and they add lots of calories without satisfying hunger,” says Avena. She suggests substituting soda for seltzer, which has no added sugar and zero calories. As for fruit-flavored beverages and fruit juice, sub in fruit-infused bottled water or water with fresh fruit slices added to it.
