The study reveals that while fasting activates stem cells responsible for repairing intestinal damage, the benefits are primarily observed after food consumption resumes, suggesting regeneration may have trade-offs.
Emmanuelle Passegue notes, 'There is a dark side that is important to consider.' This highlights the potential health risks of enhanced stem cell regeneration post-fasting, such as the development of precancerous growths.
Research indicates that the health benefits of fasting may not come from the fasting period itself, but rather from the subsequent reintroduction of food that intensifies stem cells’ regenerative capacities.
The findings illustrate how critical the timing of food intake is, with stem-cell activity peaking during the consumption phase, indicating a complex relationship between fasting and tissue repair.
