Want to reduce the risk of osteoporosis? Eat less meat, Cornell researchers say.

 

In fact, they say, reducing the amount of meat in the diet may do more to reduce the risk of osteoporosis than increasing calcium intake.

In particular, these studies suggest that high calcium intake doesn’t actually appear to lower a person’s risk for osteoporosis. For example, in the large Harvard studies of male health professionals and female nurses, individuals who drank one glass of milk (or less) per week were at no greater risk of breaking a hip or forearm than were those who drank two or more glasses per week. (2, 3) When researchers combined the data from the Harvard studies with other large prospective studies, they still found no association between calcium intake and fracture risk. (4) Also, the combined results of randomized trials that compared calcium supplements with a placebo showed that calcium supplements did not protect against fractures of the hip or other bones. Moreover, there was some suggestion that calcium supplements taken without vitamin D might even increase the risk of hip fractures.

 

Additional evidence further supports the idea that American adults may not need as much calcium as is currently recommended. For example, in countries such as India, Japan, and Peru where average daily calcium intake is as low as 300 milligrams per day (less than a third of the U.S. recommendation for adults, ages 19 to 50), the incidence of bone fractures is quite low. Of course, these countries differ in other important bone-health factors as well—such as level of physical activity and amount of sunlight—which could account for their low fracture rates.
