The EAAs in plants vary greatly due to the vast variation in the plant world and, in general, plants have much lower content of proteins than animal food. [2] [3] Some plant-based foods contain few or no EAAs, e.g. some sprouts, mango, pineapple, lime and melon. On the other hand, nuts, seeds, beans and peas contain EAAs in significant quantity.
A similar method was used to determine the protein content of foods. Test subjects were fed a diet containing no protein and the nitrogen losses recorded. During the first week or more there is a rapid loss of labile proteins. Once the nitrogen losses stabilize, this baseline is determined to be the minimum required for maintenance.
Because aspartame contains phenylalanine, foods containing aspartame sold in the US must state: "Phenylketonurics: Contains Phenylalanine" on product labels. [9] In the UK, foods that contain aspartame are required by the Food Standards Agency to list the substance as an ingredient, with the warning "Contains a source of phenylalanine ...
In the UK, foods containing aspartame must carry ingredient panels that refer to the presence of "aspartame or E951" [16] and they must be labeled with a warning "Contains a source of phenylalanine." In Brazil, the label "Contém Fenilalanina" (Portuguese for "Contains Phenylalanine") is also mandatory in products which contain it.
Animals obtain aromatic amino acids from their diet, but nearly [a] all plants and some micro-organisms must synthesize their aromatic amino acids through the metabolically costly shikimate pathway in order to make them. Histidine, phenylalanine, tryptophan, are essential amino acids for animals. Since they are not synthesized in the human body ...
Like all protein-rich foods, spirulina contains the essential amino acid phenylalanine (2.6–4.1 g/100 g), [5] which should be avoided by people who have phenylketonuria, a rare genetic disorder that prevents the body from metabolizing phenylalanine, which then builds up in the brain, causing damage. [51]
Particularly abundant flavanoids in foods are catechin (tea, fruits), hesperetin (citrus fruits), cyanidin (red fruits and berries), daidzein , proanthocyanidins (apple, grape, cocoa), and quercetin (onion, tea, apples). [2] Phenolic acids include caffeic acid; Lignans are polyphenols derived from phenylalanine found in flax seed and other cereals.
The foodstuffs listed for comparison show the essential amino acid content per unit of the total protein of the food; 100g of spinach, for example, only contains 2.9g of protein (6% Daily Value), and of that protein 1.36% is tryptophan. [2] [7] (note that the examples have not been corrected for digestibility)
