Candida (Yeast) is a late sign of impaired gut health.
Candida is associated with craving simple carbs (white foods--pasta, bread, rice, and all sugars) which feed the yeast. Candida develops for many reasons. Basically, it is a 'helper' attempting to create balance in the gut, generally due to antibiotics, preservatives, heavy metal toxins and sterile foods.
We can make candida obsolete and unnecessary by rebalancing gut microbials.
