The composition and health benefits of rye have actively been studied over a decade in Europe. The health benefits of rye are strongly linked to the dietary fibre complex, the main component of which are partially soluble arabinoxylans. The associated bioactive compounds include lignans, other phenolic compounds and vitamins.

Whole grain rye can also deliver key nutrients to consumers. Three servings of whole grain rye per day would provide 28 percent of recommended daily amounts of fiber, 15 percent magnesium, 4 percent potassium, 25 percent selenium and 60 percent manganese. In addition, this amount of rye would provide up to 10 percent of the recommended daily values of copper, iron, thiamin, niacin, folate, vitamin B6 and riboflavin.
