Biologically Active Components and Nutraceuticals in Peanuts and Related Products: Review

Peanuts are among the world's major oilseed crops. They are very nutritious with relatively high protein content and can be utilized in diverse ways. Their oil is very easily digested, and for this reason they are useful consumptives. Peanuts not only contain the so-called “good” fat (monounsaturated fat), but they are also high in a variety of helpful antioxidants, or chemicals that shield the damaging effects of free radicals. Peanuts are also a source of helpful biologically active components found in plant foods, such as phytochemicals. Some of the phytochemicals in peanuts include flavonoids and phenolic compounds. This article discusses bioactive compounds and nutraceuticals in peanuts that could be used in prevention and management of illnesses such as cancer, cardiovascular disease, osteoporosis, and other degenerative diseases. The biological activity of anti-nutritional factors in peanuts is also briefly discussed.
