Food to boost the immune system

[Wineonafridaynight]

In the past year I have had no less than 4 or 5 coldy/fluey things where I usually get really run down and usually lose my voice.

I always thought that I ate quite healthy - I eat at least 5 portions of fruit and veg a day and a good variety of other things.

My immune system must be really run down and I am keen to build it back up. Can anyone recommend any foods that I can add to my diet which may give me a boost?

I'm getting really sick of being run down and ill all the time.

Lots of aliums so onions, leeks, garlic etc. are meant to help. Yogurt for the good bugs (most of your immune system is your digestive system). Plenty of vitamin c rich foods also for coughs and colds. Cut out the booze for a bit HTH
