The health benefits of milk used to be unquestioned and a glass of milk was standard accompaniment to just about every meal. Although milk still has its advocates, several studies have been released pointing out some of its shortcomings, particularly when it comes to fat and refining
Milk is an important source of calcium and vitamin D, two essential components to build and maintain strong bones and prevent osteoporosis. Nearly all of the body’s calcium is stored in bones and teeth to support their structure. Vitamin D helps the body to take in and retain calcium. When there is not enough calcium in the body, the bones begin to break down.
An 8-ounce glass contains about 300 mg of calcium. According to United States Department of Agriculture, adults should drink three cups of milk per day.
A 2010 study published in the American Journal of Clinical Nutrition found that dieting adults who drank at least two glasses of milk every day lost an average of 12 pounds more than adults who drink little or no milk. Milk can help people feel more full and prevent hunger, and low-fat milk is a healthier choice than high-sugar fruit juices and sodas. Although the link between drinking milk and weight loss has not been elucidated, scientists believe the increased calcium consumption leads to greater loss of fat through feces.
Research has not been able to confirm that drinking milk has a direct effect on weight loss. Other studies, which it published in 2008 by Nutritional Reviews have shown that drinking milk can cause people to gain weight.
The Physicians Committee for Responsible Medicine claim that saturated fats found in milk can lead to heart disease. However, low-fat or skim milk may be heart-healthy. According to a 2008 study published in the American Journal of Clinical Nutrition, drinking just one glass of low-fat milk daily reduced an adult’s chance of developing heart disease by 37 percent.
They genetically engineered hormones found in some milk may have an impact on hormones in humans. Some studies have linked processed milk with an increased incidence of hormone-based cancers such as breast, prostate and ovarian cancer. When cows get hormone Recombinant Bovine Somatotropin (rBST), their milk production increase, but in turn they can become quite sick and infected. The infection is passed into milk and on to the consumer.
