A diet rich in the amino acid cysteine may have rejuvenating effects in the small intestine, according to a new study from MIT. This Amino Acid, the Researchers discovered, can turn on an Immune Signalling Pathway that helps Stem Cells to regrow new intestinal tissue.

This enhanced regeneration may help to heal injuries from radiation, which often occur in patients undergoing radiation therapy for Cancer. The research was conducted in mice, but if future Research shows similar results in humans, then delivering elevated quantities of Cysteine, through Diet or Supplements, could offer a new strategy to help damaged tissue heal faster, the Researchers say.
