I have a cold. I know because my nose is a little drippy and I occasionally have a bit of a sore throat. It hasn’t stopped me from working, wrangling my kid, being active, or anything else. I’m making sure to get enough sleep and eat nutrient-dense foods, with my usual range of supplements. No crappy “comfort foods.”
My immune system seems much stronger since changing my diet. Colds are usually not much more intense than this, and they don’t happen very often. I haven’t lost a day of work to my own sickness since going paleo (I have had to stay home to take care of my son). That’s a significant change: I used to get colds throughout the winter and got bronchitis every couple of years.
I am under no illusion that this makes me immune to anything in particular, but I am enjoying it for now.
