HUMAN NUTRITION

Detailed explanation-1: -Beans are incomplete proteins because they are low in one key amino acid (amino acids are used by the body to build protein) called methionine. Cereal grains-including corn, rice and wheat-are high in methionine yet lack another amino acid found in beans.

Detailed explanation-2: -If the protein you eat doesn’t have all the nine types of amino acids you need to get from food, it’s called an “incomplete protein.” Incomplete proteins examples include: Nuts and seeds. ‌Whole grains (like brown rice or whole-wheat bread) ‌Vegetables.

Detailed explanation-3: -Incomplete protein sources are most plant-based sources, including nuts, seeds, beans, legumes, whole grains, tofu, rice and vegetables. Incomplete proteins can be paired together at meals or throughout the day to make a complete protein.

Detailed explanation-4: -Every time legumes like beans, lentils, and peanuts are combined with grains like wheat, rice, and corn, a complete protein is born.
