Good or even drinkable algae and bacteria?
yogurt and milk





yogurt is a dairy product produced by bacterial fermentation of milk. Fermentation of the milk sugar (lactose) produces lactic acid, which acts on milk protein to give yogurt its texture and its characteristic tang.





Yogurt has nutritional benefits beyond those of milk: people who are lactose-intolerant can enjoy yogurt without ill effects, because the lactose in the milk precursor is converted to lactic acid by the bacterial culture. The absence of lactose bypasses the affected individuals' need to process the milk sugar themselves.





Yogurt also has medical uses, in particular for a variety of gastrointestinal conditions, and in preventing antibiotic-associated diarrhea. One study suggests that eating yogurt containing L. acidophilus helps prevent vulvovaginal candidiasis, though the evidence is not conclusive.[4]
