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 daily value (%DV) is a general guideline for consumption that will prevent deficiency of a particular nutrient in most people. The %DV refers to the percentage of an amount that's found in a single serving of a food. It also accounts for absorption factors. 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%) healthy individuals. It's more specific than the daily value, and varies by age and gender. The RDA is set by the US National Instutites of Health.
- Reference Dietary Intake (%RDI) -The reference dietary intake is similar to the recommended daily allowance, but is specific to age and gender. The RDI for amino acids is set by the U.N. World Health Organization.
- Adequate Intake (%AI) - This value is primarily used in reference to omega-3 and omega-6 fats. The Adequate Intake is set by the U.S. Institute of Medicine. Because there is less evidence to determine the ideal targets for consumption of these nutrients, the specific amount is considered to be less reliable. Using the term Adequate Intake, rather than one of the other terms, helps to emphasize that the ideal intake of that particular nutrient has not yet been scientifically determined.
See the Guide to Recommended Daily Intakes for more information.
