Question: are oats good source of protein?
Answer: Protein. Oats are a good source of quality protein at 11–17% of dry weight, which is higher than most other grains ( 22 ). The major protein in oats — at 80% of the total content — is avenalin, which isn't found in any other grain but is similar to legume proteins. The minor protein avenin is related to wheat gluten.
