Autophagy means “eating of self” (“auto”= self; “phag” = eating)[1]. Although its name might sound harmful, autophagy appears to have longevity-promoting effects[2]. Here, we will explain what autophagy is, how it works, its benefits, and how it plays a role in aging.

What is Autophagy?

Autophagy is the way cells break down misbehaving or nonfunctional organelles and proteins in the cell[1,2]. This means autophagy can consume organelles such as, mitochondria, peroxisomes, and the endoplasmic reticulum[1].
