Don't despair. I know it may feel esp difficult to stick to primal when you are not feeling your best, but actually that is the most critical time to do it!
I came down with a bad cold last week. I was pretty bummed since I had been very good about eating well. I had to leave work early and picked up a whole chicken on my way home to make chicken broth. Honestly, I swear by homemade chicken soup to lessen duration of colds. It's even known as "Jewish penicillin" I believe studies have shown that when you slowly simmer chicken bones, the nutrients that are released into the broth have immune-boosting properties.
Anyway, if you can, I'd highly recommend making some chicken broth/stock. There is a recipe on the MDA site that I used. Buying a whole chicken is cheaper (if possible, make it free-range) and if there is a butcher in your market, they'll cut it up for you. I used the two back pieces, plus one breast.
I consumed the broth (reheat by bringing to gentle boil on stovetop or microwave if you're at work) and chicken meat for about 24 hours, and my cold was basically gone the following day!!
Hope you feel better soon!!
