This is the great question of the last couple of decades. You'll find advocates for high protein diets, high carb diets, and everything in between. The important thing is what kind of carbs -- some are quite healthy and some are not.
45 to 65 percent of your daily cal. intake should be from carbohydrates. If following a 1,500-calorie diet then 675 to 975 of those calories should be from carbs 168 to 240 grams of carbohydrate. On a 2,000-calorie diet, it would be between 900 and 1,300 calories or 225 to 325 grams of carbohydrate. When choosing carbs, the focus should be on healthy carb. sources, like fruits and vegetables, along with healthier complex carbs like whole grains.
Healthy carbs. provide fuel for the body and they also contain fiber.
whole grains cannot be identified by the color of the food, look for products that have 5 grams, or 20 percent of the daily value of fiber, per serving.
