The CHina STudy found that dairy creates a metabolic acidosis in the body which tends to compromise a number of metabolic systems that in turn relate to how calcium is handled and how bone is formed. And there are more recent publications now that people have begun to dare to question dairy. A 2005 study shows a relationship with milk consumption and breast cancer. It involves total exposure to estrogen. Incidentally, osteoporosis is associated with breast cancer; they tend to go together.
A 2005 review published in Pediatrics showed that milk consumption does not improve bone integrity in children.Similarly, the Harvard Nurses’ Health Study,which followed more than 72,000 women for 18 years, showed no protective effect of increased milk consumption on fracture risk. While calcium is important for bone health, studies show that increasing consumption beyond approximately 600 mg per day—amounts that are easily achieved without dairy products or calcium supplements—does not improve bone integrity. In studies of children and adults, exercise has been found to have a major effect on bone density.
Lactose intolerance is common among many populations, affecting approximately 95 percent of Asian Americans, 74 percent of Native Americans, 70 percent of African Americans, 53 percent of Mexican Americans, and 15 percent of Caucasians
The American Academy of Pediatrics recommends that infants below one year of age not be given whole cow’s milk, as iron deficiency is more likely on a dairy-rich diet. Cow’s milk products are very low in iron.If dairy products become a major part of one’s diet, iron deficiency is more likely. Colic is an additional concern with milk consumption. Up to 28 percent of infants suffer from colic during the first month of life. We now know that breastfeeding mothers can have colicky babies if the mothers consume cow’s milk. The cow’s antibodies can pass through the mother’s bloodstream, into her breast milk, and to the baby. Additionally, food allergies appear to be common results of cow’s milk consumption, particularly in children. Cow’s milk consumption has also been linked to chronic constipation in children.
