Dietary restriction good

Dietary restriction or limited food intake without malnutrition has beneficial effects on longevity in species, including humans. A study published in a journal reveals understanding on how dietary restriction leads to increase in lifespan. Autophagy which plays a role in lifespan extension involves breaking down of the cell’s parts — its protein-making, power-generating and transport systems into small molecules. “In this study, we used the small roundworm C. elegans as a model to show that autophagy in the intestine is critical for lifespan extension,” said Malene Hansen, Associate Professor at Sanford Burnham Prebys Medical Discovery Institute.
