Foods Highest in Phenylalanine

Quick answer

In our data the foods with the highest phenylalanine per 100 g are Cottonseed kernels (2.03 g), Gruyere cheese (1.74 g), Romano cheese (1.71 g). This ranks the 498 foods that have a phenylalanine value out of 790 relevant foods; dried foods and spices are listed separately because they are concentrated. Values come unchanged from USDA FoodData Central, UK CoFID and the Canadian Nutrient File.

Coverage and limitations

• 498 of 790 relevant foods have a phenylalanine value; 292 are not ranked because the source has none.
• All amounts are per 100 g of the food as described by the source record, in g. Preparation is shown for every row and is never merged: the same food cooked differently is a separate record.
• Ranks are positions in this dataset only. Food composition varies by variety, season and processing.
• We do not show recommended intakes or health claims on this page. It is general information and not medical advice. Read more in About our data.

Questions about phenylalanine in foods

Which food has the most phenylalanine in this dataset?

Cottonseed kernels has the highest phenylalanine value in our ranking: 2.03 g per 100 g (USDA SR Legacy record 170596). This is the highest among the 498 foods with a value, not a statement about every food in existence.

What do the numbers mean?

Each value is the amount of phenylalanine in g per 100 g of the food as described by the source record, for the preparation shown on that row. The unit is g.

How complete is the data for phenylalanine?

498 of the 790 relevant foods in our data have a phenylalanine value (63%). 292 have no usable value and are not ranked; a missing value is never treated as zero.

Why are dried foods and spices listed separately?

Dried foods, powders and spices are measured in a concentrated form, so they would outrank fresh foods per 100 g. We rank 54 such foods separately (the highest is Spirulina, dried at 2.78 g).

Where do the values come from?

One source record is used per food, in a fixed order: USDA FoodData Central (Foundation Foods, then SR Legacy), then UK CoFID, then the Canadian Nutrient File. Values are never averaged. In this ranking: USDA SR Legacy (434 foods), Canadian CNF (39 foods), USDA Foundation (25 foods).
