Foods with phenylalanine


Where is phenylalanine?

Phenylalanine is an essential amino acid that the body can not synthesize and therefore must be provided by the diet.

Photo of animal protein
Photo of animal protein: aged cheese, meat, fish, seafood and eggs are rich in phenylalanine.

Almost all foods contain phenylalanine, both of plant origin, as animal origin. However, the richest foods are:

* Meat products with phenylalanine

The richest foods in this amino acid are dairy-rich proteins (such as cheese and powdered milk), meat, fish, eggs and offal.

* Plant foods with phenylalanine

Richest phenylalanine plant foods are legumes, especially soybeans and soy products (tofu, tempeh, soymilk,…). Beans, lupins, or concentrated foods such as peanut butter contain a similar amount.

Cereals such as rice, barley, oats, wheat and wheat products (bread, flour, and especially seitan) are also rich in phenylalanine.

Nuts (almonds, walnuts, hazelnuts, etc.)

Seeds: In particular, pumpkin seeds and sunflower seeds contain a lot of phenylalanine

Fruits and vegetables are low in phenylalanine.

Other sources of phenylalanine

There are other sources of this amino acid to consider:

Protein supplements or hiperproteic supplements

Gelatin desserts: When gelatin is made from fish protein it contains phenylalanine. If you want to reduce the intake of this amino acid, such as phenylketonuria, you should use gelatins with vegetable gums such as agar agar.

Aspartame sweetener: It takes part of many drinks such as soft drinks, colas, gum, etc. (Hence the importance of reading the food composition in people with phenylketonuria)

Medications: Some medications may contain phenylalanine, especially if they are sweetened.

For a correct reading of the table: Lower numbers correspond to the richest foods in phenylalanine.

A correct reading is, for example, to ingest 100mg of phenylalanine we can take 6g. of cheese (¼ slice; a very little amount of cheese) or 1 kilo of apples (about 4-6 apples, a high amount of apples). Apples have very little phenylalanine compared to other foods analyzed.
