The truth is, the U.S., England and Sweden have the highest rates of osteoporosis in the world - and the highest level of dairy consumption. American women have been getting an average of two pounds of milk per day for their entire lives, including milk, ice cream, cream, yogurt, butter etc. which is measured in pounds. It takes 10 pounds of milk to make 1 pound of cheese, 12 pounds of milk to make 1 pound of ice cream and worse of all it takes 20 pounds of milk to make 1 pound of butter - all extremely acidic or better said concentrated acid - yet 30 million American women have osteoporosis.
Drinking milk does not prevent bone loss. That's because bone loss is caused by too much protein and sugar intake, like the protein whey and the sugar lactose in dairy.
Science magazine called dietary protein the most important contributor to osteoporosis in 1986. The American Journal of Clinical Nutrition in 1995 explained that "dietary protein increases production of acid in the blood which can be neutralized by calcium mobilized from the skeleton." A study in the Journal of Nutrition in 1981 found that doubling your protein intake doubled you calcium loss. And a 1979 study in the American Journal of Clinical Nutrition found that even someone getting 1400 mg. of calcium daily can lose up to 4% of their bone mass each year on a high-protein diet. The key is not to keep drinking milk for the calcium (getting more and more protein all the while) but to reduce the excess protein in your diet so that the body has no need to leach calcium from the bones, weakening them.
To have healthy strong bones stop eating high levels of animal protein and start eating alkaline antioxidants to buffer dietary and metabolic acids, such as avocado and broccoli which have a high concentration of glutathione - the master antioxidant and protector of bones.
