Answer:
A diet combining legumes and cereals will have a good balance of essential amino acids
Explanation:
Cereals are grains that are rich in vitamins, carbohydrates, protein and other essential nutrients, they include wheat, rice, sorghum etc. Legumes include a wide range of seeds, fruits, nuts, vegetables that are rich in proteins, carbohydrates and other nutrients, examples include peas, beans, lentils etc.
Cereals and legumes are referred to as staple foods, they are usually used to complement each other because combining them will result in a good balance of essential amino acids. In cereals, lysine is a limiting amino acid but is usually in high amounts in legumes. However, in legumes cysteine, trypthophan and methionine are the limiting amino acids but are found in cereals. Therefore, this makes legumes and cereals complementary in the diet as it significantly increases the protein quality of the diet.
