most of us do not get any cold's, flu, or any other type of sickness and that is actually because of the candida from what i understand. there was a recent post about this. i can't find it right now but i think i asked the same question...why don't i ever get sick?? and apparently the candida is actually overworking the immune system, eating all other bacteria good and bad, including viruses etc. not sure if this is correct...i am sure someone else will comment. but actually normal healthy people do get sick from time to time when their immune system is healthy. i have not been sick in years and i believe it is due to candida.
