Your body plays host to a jungle of microorganisms, including Candida albicans, commonly called yeast. Although Candida is safe at normal levels, overgrowth can create an infection of the mouth, skin, vagina or other areas, causing itching, white patches or discharge. Dietary choices can help keep this fungus in check; however, you should see your doctor if you suspect yeast overgrowth.
Probiotics -- friendly bacteria -- can help you maintain a healthy internal flora balance, and Columbia Health recommends eating probiotic-rich foods to reduce Candida levels in your body. Options include sauerkraut, yogurt and kombucha, a fermented beverage. It may also help to avoid sugar and refined grains such as enriched pasta, as well as foods that contain yeast, such as bread, pizza dough, bagels and beer.
