Need a morning jolt? Try Taco Bell’s new breakfast drink, Mountain Dew A.M.
Or, on second thought—don’t. The fast-food giant’s latest concoction is equal parts Mountain Dew and orange juice. That won’t only give you a stomach ache and a mega dose of sugar, it’ll actually make you hungrier. According to a new University of Southern California study,drinking fructose and glucose increases your hunger for high-calorie foods.
Researchers gave participants 50 grams of glucose—an amount of sugar equal to a can of soda—on one occasion, and 50 grams of fructose on a separate occasion. (Sodas are typically sweetened with sugars that provide a combination of glucose and fructose.) Then they measured the participants’ desire for different foods using brain scans.
When the participants looked at pictures of food, they craved high-calorie foods like cakes, cookies, and burgers more than low-calorie fare like fruits and vegetables.
The 15-minute period after you drink fructose and gluctose is when you’re most susceptible to giving into cravings, according to the study. Your move: Stay away from sugary coffee drinks at breakfast and sodas at lunch to make sure you don’t reach for that extra doughnut or cookie.
Want a little zest in your morning drink? Add lemon, lime, or a tea bag to water, advises Jennifer Nelson, R.D., L.D., Doctor of Clinical Nutrition at Mayo Clinic Rochester. ”Your body makes all the sugar that it needs from fruits, vegetables, and whole grains,” she says.
