How the immune system identifies food vs foe

Study explains body's ability to recognise food as harmless and prevent 'attack'

- 

Israeli scientists have pinpointed a crucial network of immune cells that allows humans to digest food safely without triggering harmful reactions.

The discovery, led by researchers at the Weizmann Institute of Science (WIS), sheds new light on oral tolerance, the body's ability to recognise food as harmless and prevent an immune system attack, Xinhua news agency reported.

This vital system stops everyday foods from causing inflammation while still letting the immune system fight off infections.
