Autophagy
Autophagy is a natural process in the body where cells break down and recycle their components. The word comes from Greek, meaning "self-eating." It is a critical mechanism that helps maintain cellular health by removing damaged or unnecessary cellular materials, including proteins, organelles, and other cellular debris, repurposing them for energy, or building new cellular components.

Autophagy plays a role in overall health and longevity. Promoting autophagy can help reduce inflammation, support immune function, and protect against age-related diseases. Certain practices, such as fasting or caloric restriction, are thought to stimulate autophagy, as the body shifts to breaking down internal resources when external food sources are limited.
