How much calcium to you need?
There is no simple answer as there are many factors that influence any one nutrient recommendation. While the national recommendations usually put out a single number for certain ages and genders, the reality is, there are many factors that influence actual needs for everyone.
There are populations around the world that do no have osteoporisis yet have calcium intakes in the 300-500 range. Most of them also have total protein intakes about half of the USA and animal protein intakes of 1/4 to 1/7 of the USA.
While we often hear about the impact of animal protein, there are many other factors that may play as big if not a bigger role. These inlude Vit D, Vit K, sodium, magnesium, boron, weight bearing exercise, etc.
There is evidence that if Vit D intake is adequate, calcium needs go down and getting adequate Vit D may as important if not more important than getting in adequate calcium. Same with sodium (as we discussed a few weeks ago). Studies on Vit K have shown that adequate Vit K (which is abundant in leafy greens) may reduce fracture risk by about 30%. Smoking and caffeine, are other factors that also play a role.

I recently wrote two article on the relationship between bodyweight, BMI and longevity and how those who tend to be slightly underweight may live the longest. Unfortunately, the trend to being overweight is rapidly expanding.
A new study, from Johns Hopkins Bloomberg School of Public Health, the Agency for Healthcare Research and Quality, and the University of Pennsylvania School of Medicine, projects the majority of U.S. adults to be overweight or obese by 2030. This study was just published in the July 2008 online issue of Obesity,
The amount of Americans who are overweight and obese has risen dramatically since 1980. Currently, about 65% of Americans are overweight with 33% of them being obese. According to the new study, if these trends continue, more than 86 percent of adults will be overweight or obese by 2030 with approximately 96 percent of non-Hispanic black women and 91 percent of Mexican-American men affected.
In addition, obesity-related health costs are expected rise to about $956.9 billion, according to the study. Dr. Youfa Wang, the lead author of the study and associate professor with the Bloomberg School's Center for Human Nutrition said in a press release, "This would result in 1 of every 6 health care dollars spent in total direct health care costs paying for overweight and obesity-related costs,”
