A diet that contains adequate amounts of amino acids (especially those that are essential) is particularly important in some situations: during early ...
Animal-source foods are a diverse group of foods that are rich in bioavailable nutrients including calcium, iron, zinc, vitamins B12, vitamin D, choline, DHA, and EPA.

The quality and quantity of usable meat depends on the animal's plane of nutrition, i.e., whether it is over- or underfed.

[13] The composition of the diet, especially the amount of protein provided, is an important factor regulating animal growth.

[2] Many do not eat food from animal sources to varying degrees (e.g. flexitarianism , pescetarianism , vegetarianism , and veganism ) for health reasons, issues surrounding morality, or to reduce their personal ...
