Wheatgrass (Triticum aestivum L.) supplementation promotes longevity in Drosophila melanogaster

Abstract

Wheatgrass is a rich source of vitamins, antioxidants and minerals in a bioavailable form. Traditionally, the juice of wheatgrass is used in the treatments of various diseases such as asthma, cancer, arthritis, diabetes, cardiovascular diseases etc. To promote longevity and life span, edibles containing high antioxidant capacities and other bio actives are considered to be ideal.  We intended to test the activity of wheatgrass to counteract oxidative stress, which is one of the major causes of various diseases and ageing. In the present study, Oregon R⁺ strain of Drosophila melanogaster was fed on standard diet (normal Drosophila diet), and diet supplemented with wheatgrass extract (10mg/mL). Our experiments suggest that supplementation of wheatgrass reduces oxidative stress and improves longevity in Oregon R⁺ flies.
