_______ consume grains, vegetables, fruits, legumes, seeds, nuts, dairy foods, and eggs, but do not consume meat, fish, and poultry.

small intestine

After a meal, the majority of protein digestion and absorption occurs in the small intestine. Chemical digestion of protein begins after chewed food enters the stomach. Hydrochloric acid breaks down the bonds of protein strands and activates pepsin, a digestive enzyme, which breaks the protein into shorter polypeptide strands. In the small intestine, proteases further break down protein strands into tripeptides and dipeptides, as well as some amino acids. The protein remnants are then absorbed into the cells of the small intestine lining, where the remaining tripeptides and dipeptides are broken down into single amino acids that are then released into the bloodstream.

In the mouth, mechanical digestion of protein begins with chewing, tearing, and mixing of food with salivary juices to form a bolus, or soft mass of chewed food.

The pancreas produces enzymes, including proteases, that are released into the small intestine via the pancreatic duct.

chicken breast

A chicken breast is a source of complete protein. A protein that provides all nine of the essential amino acids, along with some of the 11 nonessential amino acids, is considered a complete protein. Protein from animal sources, such as meat, fish, and poultry, is typically complete protein. Soy, a plant protein, is also a complete protein.

A protein that is low or deficient in one or more of the essential amino acids is considered an incomplete protein. Protein from plant foods (such as vegetables, grains, and beans) tends to be incomplete; however, you can obtain a complete protein by combining complementary foods, such as rice and beans.

there is a severe deficiency of protein in the diet but an adequate intake of energy

Kwashiorkor develops when there is a severe deficiency of protein in the diet but an adequate intake of energy. With protein deficiency, fluid accumulates in the spaces surrounding the cells, causing edema (swelling) in the legs, feet, and abdomen. Muscle proteins are broken down to generate the amino acids needed to synthesize critical functional proteins.
Animal protein in the diet is not necessary, because people can meet their protein needs from a combination of plant proteins, such as soy and other legumes, grains, and vegetables, as part of a well-balanced diet.
Marasmus is a condition in which there is a severe deficiency of energy intake, including protein intake.

soy milk

Soy milk is a source of complete protein. Although plant protein is typically not complete protein, soy is an exception. Soy foods, such as soy milk, provide all the essential amino acids a body needs, along with some nonessential amino acids, and thus are a source of complete protein.

Protein from animal sources, such as meat, fish, and poultry, is typically complete protein, whereas protein from plant foods tends to be incomplete. Kidney beans, peanut butter, and pasta are missing adequate amounts of some essential amino acids.

Unless carefully planned, vegan diets may be low in which of the following essential micronutrients?

vitamins D and B12, calcium, and iron
vitamins C and E, thiamin, and calcium
vitamins K and E, potassium, and magnesium
Vitamin B12, folate, sodium, and potassium

vitamins D and B12, calcium, and iron

Unless carefully planned, vegan diets may lack vitamins D and B12, calcium, and iron. These vitamins and minerals, as well as protein, zinc, vitamin A, and omega-3 fatty acids, are abundant in animal-based foods, which a vegan diet does not include. Animal-based foods are the only naturally occurring food source of B12, so it is extremely important that vegans consume fortified foods or a supplement to meet their daily needs.

A well-planned vegan diet that includes a range of fruits, vegetables, legumes, grains, and vegetable oils provides ample amounts of vitamins C, E, and K, thiamin, and folate, as well as sodium, potassium, and magnesium. Although vitamin A is found only in animal-based foods, vegans can get adequate amounts by consuming beta-carotene, a plant pigment that is converted to vitamin A in the body.
