Candida (Yeast Bacteria) is present at all times. It is normal for this bacteria to be found in the intestines & hence your faeces.
From what I remember about an article on the immune system & Probiotics. I understand a little more about bacteria & Intestines.
We need 85% good bacteria & 15% bad bacteria!! This is the preferred percentage balance for our intestines to perform their role correctly.
Coffee, anti-biotics and a thousand other things can easily alter the balance and these bad bacteria guys take a little too much control!!!
This lack of balance is where the candida bacteria tend to increase & flourish which causes all sorts of terrible problems.
I actually decided to start taking probiotics myself because I drink a fair bit of coffee.
There are lots to choose from but not all probiotics are the same. Anyway, I have finally got my head around swallowing living little bacteria!!!
It took me a while to actually decide to give it ago. No regrets so far.
So load up with good bacteria and they will push the candida bacteria back into line!!
