The protein one eats\u00a0is digested into amino acids. Amino acids from meat, milk, eggs, beans, and fish link together to form thousands of different proteins that become part of the body.<\/em>\u00a0Proteins form the structure of the\u00a0body; other proteins become antibodies to fight off infection, and still other proteins control and regulate cell activities.<\/p>\r\n\r\n

FYI: Twelve to eighteen percent of the body is made up of protein. Proteins do a variety of jobs in the body: They regulate body functions, build muscles and bones, make muscles contract, help fight illness, transport substances in the blood, and transmit information between cells.<\/div>\r\n

Protein is necessary for good health\u00a0throughout all stages of life.<\/p>\r\n

More\u00a0protein is needed when the body is growing rapidly especially during infancy and adolescence. \u00a0Growth and development can be inhibited by\u00a0protein deficiency. Some of the missed growth cannot be made up later; therefore, it is important to maintain a healthy, balanced diet that includes appropriate sources of protein.<\/p>\r\n\r\n

Complete vs Incomplete Protein<\/h2>\r\nIn nutrition, the quality of protein refers to types,\u00a0amounts, and\u00a0accessibility of amino acids in the food.\r\n\r\nProteins can be classified as either complete or incomplete.\r\n\r\nProteins that contain adequate amounts of all nine essential amino acids are termed complete proteins.\u00a0Incomplete proteins do not contain adequate amounts of one or more of the essential amino acids. For example, if a protein doesn\u2019t provide enough of the essential amino acid leucine, it would be considered incomplete.\r\n

Animal\u00a0Sources of Protein<\/h2>\r\nMeat, poultry, fish, eggs, and milk products are considered complete proteins. A balanced diet that includes all food groups in appropriate amounts will supply the necessary macronutrients needed daily.\r\n

Plant Sources of Protein<\/h2>\r\n

Plants are a source of protein but are not a complete protein unless combined with other sources of essential amino acids. Complimentary proteins are food sources that work together to provide all essential amino acids. By focusing on complimentary proteins, vegetarians can achieve an appropriate daily protein intake.<\/p>\r\n

Complementary proteins do not need to be consumed at the same time or meal. It is currently recommended that essential amino acids needs be met on a daily basis, meaning that if a grain is consumed at one meal, a legume could be consumed at a later meal, and the proteins would still complement one another.<\/p>\r\n

FYI: It is important to know that the\u00a0body does not store excess amino acids like it stores excess carbohydrates or fat. Therefore, one has to get all of the amino acids needed\u00a0every<\/span> day.<\/div>\r\n
