Yogurt aids healing after intestinal infections. Some viral and allergic gastrointestinal disorders injure the lining of the intestines, especially the cells that produce lactase. This results in temporary lactose malabsorption problems. This is why children often cannot tolerate milk for a month or two after an intestinal infection. Many pediatricians recommend yogurt for children suffering from various forms of indigestion.
Research shows that children recover faster from diarrhea when eating yogurt.
It's good to eat yogurt while taking antibiotics. The yogurt will minimize the effects of the antibiotic on the friendly bacteria in the intestines. The live bacterial cultures in yogurt can help replenish the intestines with helpful bacteria before the harmful ones take over. A 1999 study reported in Pediatrics showed that lactobacillus organisms can reduce antibiotic-associated diarrhea. Yogurt can decrease yeast infections.
