Lay off the dairy. Seriously, just while you are ill, some studies have shown that dairy products prolong viruses. Go for raw fruits and veggies, as much pure juice as you can, and lean proteins. Chicken soup is not a myth, but it should be home made. Vitamins C, A, K, and E are vital. That's why I love Naked Juice for sick peeps. Traditional Medicinal puts out some specific teas for colds and flues that I keep in stock this time of year too. Slippery Elm tea can be a lifesaver.
