I'm sick at least 1-2 or more times a month (moderate-severe colds). When I'm not "sick" I'm coughing all the time. I take a probiotic every day, and even since eating strict whole30 I've been sick twice (in 3 weeks). This has been going on for years regardless of what my diet is. Why am I always sick?
Edit: I've been eating paleo for 3 years so I don't think it's my body transitioning to low carb. I change around what I eat now and then within paleo eating and there's been no difference in my colds.
