Nutrition Sources of Protein

Complementing plant proteins at each meal is not necessary if total daily calories and protein are adequate and the diet includes a variety of protein sources, such as dairy or legumes, nuts and seeds. Aim for at least 1/3-1/2 of your day’s protein from foods above the dashed line, more if you are following a modified carbohydrate plan. Research has shown that 25-30 grams of soy protein daily may lower cholesterol by about 10%.
