The U.S. Department of Agriculture recommends that adults consume approximately 3 cups of dairy daily as part of a healthy diet, and drinking milk on a regular basis helps you achieve this goal. Drinking milk provides a source of several essential nutrients, including vitamins and minerals. While each nutrient plays a distinct physiological role in your body, some of the nutrients in milk benefit your eyes and skin.-MDA

Study finds high milk consumption linked to higher mortality, hip fractures
If you drink milk to keep your bones strong, there’s good logic in it. Milk and dairy products are concentrated calcium sources, and we know calcium fortifies bones and prevents osteoporosis.
However, a recent study suggests that while some milk may be good, more is not better. In fact, too much milk may be bad for your health.
The study, conducted with over 60,000 women (age 39-74) and 45,000 men (age 45-79) found that too much milk – three or more glasses a day – was not only associated with mortality but also an increased risk of fracture and hip fracture. Researchers found this surprising association after following the men and women in this study for 22 and 13 years respectively. Over this time, study participants completed questionnaires about their milk-drinking habits.
After adjusting for a other variables, they found that women who reported drinking three or more glasses of milk each day nearly doubled their risk of death in relation to women who drank less than one glass each day. Men were not as affected as women, but those who drank three or more glasses of milk each day still showed a significant increase in mortality.
Interpreting the results
Does this mean you shouldn’t drink milk? Don’t go shunning the jug just yet.
There are details to consider in understanding these study results, experts say. While milk and dairy are among the most calcium-rich foods you can eat, there are other substances in milk that may warrant some moderation.
The authors note that D-galactose, found in milk, has been shown to induce oxidative stress damage and chronic inflammation in animals, and such changes have been associated with cardiovascular disease, cancer, bone loss, and muscle loss in humans. They also caution that their findings “merit independent replication before they can be used for dietary recommendations.”
Gail Cresci, PhD, RD, a Cleveland Clinic researcher and dietitian , did not participate in the study but she agrees with the authors’ assessment. She says while the study raises interesting questions, there is not strong enough evidence to warrant a restriction on milk.
The role of vitamin D
She says there are some unanswered questions about the study participants – and whether or not they were lacking in vitamin D……….
