1. Yogurt is easier to digest than milk. The live active cultures create lactase, the enzyme lactose-intolerant people lack, and another enzyme contained in some yogurts (beta-galactosidase) also helps improve lactose absorption in lactase-deficient persons. Bacterial enzymes created by the culturing process, partially digest the milk protein casein, making it easier to absorb and less allergenic.
2. Yogurt contributes to colon health. Yogurt contains lactobacteria, intestines-friendly bacterial cultures that foster a healthy colon, and even lower the risk of colon cancer. Lactobacteria, especially acidophilus, promotes the growth of healthy bacteria in the colon and reduces the conversion of bile into carcinogenic bile acids.
Secondly, yogurt is a rich source of calcium - a mineral that contributes to colon health and decreases the risk of colon cancer. Calcium discourages excess growth of the cells lining the colon, which can place a person at high risk for colon cancer. Calcium also binds cancer-producing bile acids and keeps them from irritating the colon wall.
3. Yogurt improves the bioavailability of other nutrients. Culturing of yogurt increases the absorption of calcium and B-vitamins. The lactic acid in the yogurt aids in the digestion of the milk calcium, making it easier to absorb.
4. Yogurt can boost immunity. Researchers who studied 68 people who ate two cups of live-culture yogurt daily for three months found that these persons produced higher levels of immunity boosting interferon. The bacterial cultures in yogurt have also been shown to stimulate infection-fighting white cells in the bloodstream.
5. 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. 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.
6. Yogurt can decrease yeast infections. Research has shown that eating eight ounces of yogurt that contains live and active cultures daily reduces the amount of yeast colonies and decreases the incidence of yeast infections.
7. Yogurt is a rich source of calcium. An 8-ounce serving of most yogurts provides 450 mg. of calcium, one-half of a child's RDA and 30 to 40 percent of the adult RDA for calcium. Because the live-active cultures in yogurt increase the absorption of calcium, an 8-ounce serving of yogurt gets more calcium into the body than the same volume of milk can.
8. Yogurt is an excellent source of protein. Plain yogurt contains around ten to fourteen grams of protein per eight ounces, which amounts to twenty percent of the daily protein requirement for most persons. In fact, eight ounces of yogurt that contains live and active cultures, contains 20 percent more protein than the same volume of milk (10 grams versus 8 grams). Besides being a rich source of proteins, the culturing of the milk proteins during fermentation makes these proteins easier to digest. For this reason, the proteins in yogurt are often called "predigested."
9. Yogurt can lower cholesterol. There are a few studies that have shown that yogurt can reduce the blood cholesterol. This may be because the live cultures in yogurt can assimilate the cholesterol or because yogurt binds bile acids, (which has also been shown to lower cholesterol), or both.
10. Yogurt is a "grow food." Two nutritional properties of yogurt may help children with intestinal absorption problems grow: the easier digestibility of the proteins and the fact that the lactic acid in yogurt increases the absorption of minerals. And even most picky-eaters will eat yogurt in dips and smoothies and as a topping.
