Top 10 Foods Highest in Phenylalanine
Phenylalanine is an essential amino acid involved in creating brain signaling molecules such as dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline). (1) Phenylalanine can also be used by the body to make the amino acid tyrosine. (2)
Phenylalanine is used as an ingredient in artificial sweeteners containing aspartame and may have negative health effects if consumed in high amounts. People suffering from Phenylketonuria should limit their intake of phenylalanine. (3)
High phenylalanine foods include beef, chicken, pork, tofu, fish, beans, milk, nuts, seeds, pasta, whole grains, and vegetables like sweet potatoes.
The reference dietary intake (RDI) for phenylalanine and tyrosine is 25mg per kilogram of body weight or 11mg per pound. (4) Assuming a person gets half their requirement from each amino acid, a person can then consume 12.5mg per kg or 5.5mg per pound. As such, a person weighing 70kg (~154 pounds) should consume around 875mg of phenylalanine per day, and this is the amount used to calculate the reference dietary intake (RDI). If you only plan to consume phenylalanine, and no tyrosine, you should double the RDIs.

About Nutrient Targets
Setting targets can provide a guide to healthy eating.
Some of the most popular targets include:- Daily Value (%DV) - The %DV is a general guideline for everyone and accounts for absorption factors. It is the most common target in the U.S. and is the target on the nutrition labels of most products. It is set by the U.S. FDA.
- Recommended Dietary Allowance (%RDA) - The RDA sets an average daily dietary intake level that is sufficient to meet the nutrient requirements of nearly all (97.5 percent) healthy individuals and is specific to age and gender. The RDA is set by the US National Instutites of Health.
- Adequate Intake (%AI) - Sets a target for Omega 3 and Omega 6 fats. The Adequate Intake is also set by the U.S. Institute of Medicine. It represents a number to ensure adequacy but lacks the same level of evidence as the Reference Dietary Intake. In short, the number is less accurate than the RDI.
- Reference Dietary Intake (%RDI) -The reference dietary intake is similar to the recommended daily allowance, and is specific to age and gender. The RDI for amino acids is set by the U.N. World Health Organization.
See the Guide to Recommended Daily Intakes for more information.
