HUMAN NUTRITION

Detailed explanation-1: -Plant foods are considered incomplete protein s because they are low or lacking in one or more of the amino acids we need to build cells. Incomplete proteins found in plant foods can be mixed together to make a complete protein.

Detailed explanation-2: -Plant proteins, mostly globulins, have been obtained chiefly from the protein-rich seeds of cereals and legumes. Small amounts of albumins are found in seeds. The best known globulins, insoluble in water, can be extracted from seeds by treatment with 2 to 10 percent solutions of sodium chloride.

Detailed explanation-3: -Incomplete Protein Foods. According to Harvard Health Publishing, all animal-based foods, including meat, dairy, and eggs, contain complete protein. The majority of plant-based protein sources, such as whole grains, legumes, seeds and nuts, spinach, broccoli, and mushrooms, are incomplete.
