Does anyone know of any good food for boosting the immune system? In the last two/three months I've had constant colds, viruses and a stomach bug 
I've recently become vegetarian but would say I am eating a balanced diet, getting plenty of fruits/veg. Currently the only supplement I take is folic acid, and occasionally evening primrose oil. I would prefer not to take other supplements, so would like to know of some super foods for boosting the immune system.
Any ideas would be really appreciated.
