Results of a new study on mice and a phase 1 trial of humans suggest that prolonged cycles of fasting - for 2-4 days at a time - not only protect against toxic effects of chemotherapy, but also trigger stem cell regeneration of new immune cells and clearing out of old, damaged cells.
The team believes the findings could benefit people with immune system damage, for example if they have receivedchemotherapy treatment for cancer. It could also benefit the elderly whose immune systems are weakened through aging, making them more susceptible to disease.
