As Telegraph reported, 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, scientists have found in a breakthrough described as ‘remarkable.’”
The latest research suggests that fasting stimulates cells to produce new white blood cells, which could help in the fight against any infection.
They also found that fasting may also help people with poor immune system, including cancer patients who receive chemo.
Fasting is also beneficial for older people, as their immune system weakens due to the aging process, so they are not able to fight even common diseases.
Scientists explain that fasting “flips a regenerative switch,” which kick-starts stem cells to create new white blood cells, essential for the regeneration of the immune system.
Valter Longo is a corresponding author of the study and also a professor at the USC Davis School of Gerontology. According to him, “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.”
