The effect of resveratrol on lifespan depends on both gender and dietary nutrient composition in Drosophila melanogaster.

Resveratrol, a polyphenolic compound, has been shown to extend lifespan in different organisms. Emerging evidence suggests that the prolongevity effect of resveratrol depends on dietary composition. However, the mechanisms underlying the interaction of resveratrol and dietary nutrients in modulating lifespan remain elusive.

Gender-specific prandial response to dietary restriction and oxidative stress in Drosophila melanogaster.

Drosophila melanogaster is ideal for studying lifespan modulated by dietary restriction (DR) and oxidative stress, and also for screening prolongevity compounds. It is critical to measure food intake in the aforementioned studies. Current methods, however, overlook the amount of the food excreted out of the flies as feces or deposited in eggs.

Açai palm fruit (Euterpe oleracea Mart.) pulp improves survival of flies on a high fat diet.

Reducing oxidative damage is thought to be an effective aging intervention. Açai, a fruit indigenous to the Amazon, is rich in phytochemicals that possesses high anti-oxidant activities, and has anti-inflammatory, anti-cancer and anti-cardiovascular disease properties. However, little is known about its potential anti-aging properties especially at the organismal level.
