In our most recent past, American women have been consuming an average of two pounds of milk per day for their entire lives, yet thirty
million American women have osteoporosis. Does this make sense?
In short, drinking milk does not prevent bone loss. The shocking part is that bone loss is actually accelerated by ingesting too much protein which
forces the body to leech calcium from the bones to lower the acid level in the body. It's not how much calcium you eat. It's how much calcium you prevent from leaving your bones.
WHY DOES CALCIUM LEAVE BONES FROM MILK?
(find out why)
In order to absorb calcium, the body needs comparable amounts of another mineral element, magnesium. Milk and dairy products contain only small amounts of magnesium. Magnesium is the center atom of
- "Osteoporosis is caused by a number of things, one of the most important being too much dietary protein."
- "Countries with the highest rates of osteoporosis, such as the United States, England, and Sweden, consume the most milk.
China and Japan, where people eat much less protein and dairy food, have low rates of osteoporosis."
Nutrition Action Healthletter, June, 1993
- "What appears to be important in bone metabolism is not calcium intake, but calcium balance.
The loss of bone integrity among many post menopausal white women probably results from genetics and from diet and lifestyle factors. Research shows that calcium losses are increased by the use of animal protein, salt, caffeine, and tobacco, and by physical inactivity."
Neal Barnard, M.D., Physician's Committee for Responsible Medicine, Understanding Health, December, 1999
- "Dietary protein increases production of acid in the blood which can be neutralized by calcium mobilized from the skeleton."
American Journal of Clinical Nutrition, 1995; 61 (4)
- "About 50,000 Americans die each year of problems related in some way to osteoporosis."
Osteoporosis International 1993;3(3)
- "Even when eating 1,400 mg of calcium daily, one can lose up to 4% of his or her bone mass each year while consuming a high-protein diet."
American Journal of Clinical Nutrition 1979;32(4)
- "Increasing one's protein intake by 100% may cause calcium loss to double."
Journal of Nutrition, 1981; 111 (3)
- "The average man in the US eats 175% more protein than the recommended daily allowance and the average woman eats 144% more."
Surgeon General's Report on Nutrition and Health, 1988
- "Calcium intake demonstrated no protective in preventing bone fractures. In fact, those populations with the highest calcium intakes had higher fracture rates than those with more modest calcium intakes.
Calif Tissue Int 1992;50
- "There is no significant association between teenaged milk consumption and the risk of adult fractures. Data indicate that frequent milk consumption and higher dietary calcium intakes in middle aged women
do not provide protection against hip or forearm fractures... women consuming greater amounts of calcium from dairy foods had significantly increased risks of hip fractures, while no increase in fracture risk
was observed for the same levels of calcium from nondairy sources."
12-year Harvard study of 78,000 women American Journal of Public Health 1997;87
- "Consumption of dairy products, particularly at age 20 years, were associated with an increased risk of hip fractures...metabolism of dietary protein causes increased urinary excretion of calcium.
