Go ahead an eat toast if you want toast. A new study suggests following a moderate-carb diet might help you live longer. Researchers followed more than 15,000 people in the U.S. for a median of 25 years and found that low-carb diets (less than 40 percent of calories from carbs) and high-carb diets (more than 70 percent of calories from carbs) were associated with an increased risk of premature death. Moderate consumption of carbs (50 to 55 percent of calories) was associated with the lowest risk of early death. They also discovered that sticking to a low-carb diet that mostly involves eating animal-based proteins and fats from foods such as pork, chicken and cheese instead of carbs was associated with a greater risk of dying early, while eating more plant-based proteins and fats from foods like vegetables and legumes, and nuts lowered the risk of early death. Still, researchers admit that participants’ eating habits were self-reported, and their diets could’ve changed during the 25-year-long study, which could affect the link between carbohydrate intake and longevity.
