What are the benefits of autophagy?
The main benefits of autophagy seem to come in the form of anti-aging principles. In fact, Petre says it’s best known as the body’s way of turning the clock back and creating younger cells.
Khorana points out that when our cells are stressed, autophagy is increased in order to protect us, which helps enhance your lifespan.
Additionally, registered dietitian, Scott Keatley, RD, CDN, says that in times of starvation, autophagy keeps the body going by breaking down cellular material and reusing it for necessary processes.
“Of course this takes energy and cannot continue forever, but it gives us more time to find nourishment,” he adds.
At the cellular level, Petre says the benefits of autophagy include:
- removing toxic proteins from the cells that are attributed to neurodegenerative diseases, such as Parkinson’s and Alzheimer’s disease;
- recycling residual proteins;
- providing energy and building blocks for cells that could still benefit from repair;
- on a larger scale, it prompts regeneration and healthy cells.
Autophagy is receiving a lot of attention for the role it may play in preventing or treating cancer, too.
“Autophagy declines as we age, so this means cells that no longer work or may do harm are allowed to multiply, which is the MO of cancer cells,” explains Keatley.
While all cancers start from some sort of defective cells, Petre says that the body should recognize and remove those cells, often using autophagic processes. That’s why some researchers are looking at the possibility that autophagy may lower the risk of cancer.
While there’s no scientific evidence to back this up, Petre says some studiesTrusted Source suggest that many cancerous cells can be removed through autophagy.
“This is how the body polices the cancer villains,” she explains. “Recognizing and destroying what went wrong and triggering the repairing mechanism does contribute to lowering the risk of cancer.”
Researchers believe that new studies will lead to insight that will help them target autophagy as a therapy for cancer.
