First, we feared eating too much fat. Then, the pendulum shifted, and we started to eye carbs as the enemy. But what’s the real deal? Now, a global study published in The Lancet is challenging the notion that one necessarily needs to be worse than the other: Rather, it might be that eating too much or too little of the nutrients is the actual problem. Researchers from McMaster University in Canada followed more than , people in 18 countries—from South America to Africa to China—for about seven years. After analyzing survey data about their diet and health, the researchers found that people who ate more than 68 percent of their total calories from carbohydrates were 28 percent more likely to die during the follow up than those who took in a lesser percentage of their calories from carbs. The nutritional breakdown of carbs is important, since previous studies suggest that foods with a high glycemic index—meaning they spike your blood sugar faster, like refined carbs tend to do—can increase your risk for several chronic diseases, like obesity and diabetes, says Dehghan. So while we don’t advise cutting your carbs, we do recommend the majority of them come from complex sources, like whole grains and vegetables.
