What we know as the 'new' food pyramid was unveiled by the United States Department of Agriculture in an attempt to make the daily food intake amounts more accurate. Instead of tiers, the new food pyramid has highlighted sectors and instead of servings, the new pyramids shows a daily amount to be consumed based on a 2000 calorie diet. You could modify this recommended intake as per your dietary calorie requirement depending on whether you are going for weight gain or weight loss.
