We all know that eating yogurt can be a healthy choice. A cup of yogurt has about one third of our daily calcium need, and is a good source of protein, with about 10 grams per serving.

Yogurt is a dairy product produced by the bacterial fermentation of milk. It's a biological process, similar to the fermentation of grapes to produce wine. Most yogurts are made from cow's milk, but some are also produced from sheep's and goat's milk, in addition to soy. These products are great options for those with lactose intolerance or a milk-protein allergy.
