Yogurt is a fermented dairy product and the culturing process makes yogurt more digestible than milk.
The culturing process breaks down the milk sugar lactose into glucose and galactose, two sugars that are easily absorbed by lactose-intolerant individuals. Plus bacterial enzymes in the live culture partially digest the milk protein casein, making it easier to absorb and less allergenic. Note yogurt has less lactose than milk.
1 cup of yogurt (250 grams) provides about 13 grams of protein
1 cup of Milk (250 grams) provides about 8.4 grams of protein
100 grams of cheese provides about 24.5 grams of protein
A cup of Yogurt provides about 30% of the daily value for Calcium and 23% of the daily value of phosphorus both play a vital role in a process known as bone mineralization, to form calcium phosphate a major part of hydroxyapatite that gives structure and strength to bones.
Daily consumption of 3 ounces or 100 grams yogurt (containing health promoting bacteria) significantly improves the cholesterol profile, by lowering LDL (bad) cholesterol and raising HDL (good) cholesterol especially in women1.
