A group of scientists at the University of Southern California (USC) have discovered that fasting “for as little as three days can regenerate the entire immune system, even in the elderly people”.
According to their latest research, fasting stimulates cells to produce new white blood cells, which help fighting against any infection. Fasting may also help including cancer patients who receive chemo.
Fasting is remarkably beneficial for people with poor immune system, especially older people, as their immune system weakens due to the aging process, so they are not able to fight even common diseases, and also patients who receive chemotherapy. Valter Longo, a corresponding author of the study and also a professor at the’ USC Davis School of Gerontology’ states: “when you starve, the system tries to save energy, and one of the things it can do to save energy is to recycle a lot of the immune cells that are not needed, especially those that may be damaged.”
Longo also explained, “With a system heavily damaged by chemotherapy or aging, fasting cycles can generate, literally, a new immune system.”
