COW'S MILK


Cow's milk, the basis for all other dairy products, promotes strong bones by being a very good source of vitamin D and calcium, and a good source of vitamin K--three nutrients essential to bone health. In addition, cow's milk is a very good source of iodine, a mineral essential for thyroid function; and a very good source of riboflavin and good source of vitamin B12, two B vitamins that are necessary for cardiovascular health and energy production. Cow's milk is also a good source of vitamin A, a critical nutrient for immune function, and potassium, a nutrient important for cardiovacular health. Milk produced by grass fed cows also contains a beneficial fatty acid called conjugated linoleic acid (CLA). Researchers who conducted animal studies with CLA found that this fatty acid inhibits several types of cancer in mice. In vitro (test tube) studies indicate this compound kills human skin cancer, colorectal cancer and breast-cancer cells. Other research on CLA suggests that this beneficial fat may also help lower cholesterol and prevent atherosclerosis. Calcium--A Mineral for A Lot More than Strong Bones Cow's milk may be best known as a very good source of calcium. Calcium is widely recognized for its role in maintaining the strength and density of bones. In a process known as bone mineralization, calcium and phosphorous join to form calcium phosphate. Calcium phosphate is a major component of the mineral complex (called hydroxyapatite) that gives structure and strength to bones. A cup of cow's milk supplies 29.7% of the daily value for calcium along with 23.2% of the DV for phosphorus. Building bone is, however, far from all that calcium does for us. In recent studies, this important mineral has been shown to: Help protect colon cells from cancer-causing chemicals Help prevent the bone loss that can occur as a result of menopause or certain conditions such as rheumatoid arthritis Help prevent migraine headaches in those who suffer from them Reduce PMS symptoms during the luteal phase (the second half) of the menstrual cycle Help prevent childhood obesity Help overweight adults lose weight, especially around the midsection.
