Proper calcium supplement early in life key to lifelong bone health

Washington, May 14 (ANI): A new study has revealed that not only is calcium required for strong and healthy bones, it could also play a vital role in determining bone health for life.

The new research from North Carolina State University conducted an 18-day trial involving 24 newborn pigs, half of which were fed a calcium deficient diet, and the other half, calcium rich diet.

They found that the bone densities in the pigs that were fed the calcium-deficient diet were lower as compared to that of the other half. Moreover, certain stem cells in bone marrow, in the calcium-deficient piglets appeared to have already been programmed to become fat cells instead of bone-forming cells.

However, blood tests didn”t indicate any difference in levels of the hormonal form of vitamin D, which regulates the amount of calcium circulating in the blood of older children and adults. Dr. Chad Stahl, an associate professor of animal science who led the study, said this suggests that calcium regulation in newborns isn”t dependent on vitamin D.

Because these programmed mesenchymal stem cells replicate to provide all the bone-forming cells for an animal”s entire life, very early calcium deficiency may have predisposed the piglets to have bones that contain more fat and less mineral. That could make those pigs more prone to osteoporosis and obesity in later life, said Stahl.

The researchers plan to extend this study to see if the calcium deficiency in early life in the piglets also has an impact on sexual maturity.

The researchers are using pigs as a model for human health because pigs and humans are similar when it comes to bone growth and nutrition. Pigs are one of the few animals known to experience bone breaks related to osteoporosis, Stahl said.

“For me,” Stahl said, “the biggest message is that calcium nutrition, or mineral nutrition as a whole, needs to be a priority from day one. Early life nutrition is setting children up physiologically for the rest of their lives.” (ANI)

How dairy foods are nutritional bang for the buck

Washington, July 2 (ANI): A daily consumption of dairy products like milk, cheese, and yogurt can provide a unique package of nine essential nutrients at a low cost per serving, according to a recent review.

Several prominent nutrition researchers have detailed an updated review of the health benefits of consuming dairy foods, which contributes to the well-established evidence that consuming three to four daily servings of dairy foods each day is a convenient and affordable way to get several key nutrients.

Dairy products help in improving the following:

Child nutrition

Children and adolescents between the ages of 9-18 need, on average, four servings of dairy foods a day to meet calcium recommendations and at least three servings to meet magnesium recommendations. Adolescents who do not regularly consume dairy, on average, only meet 40 percent of the Adequate Intake for calcium.

Bone health

The evidence supports the 2005 Dietary Guidelines for Americans recommendation to meet nutrient needs through foods, including dairy foods, rather than supplements. Studies continue to show that dairy foods provide a unique nutrient package beneficial for bone mass and play a major role in lifelong bone health.

Cardiovascular health

Low-fat and fat-free dairy foods play a key role in the Dietary Approaches to Stop Hypertension (DASH) diet, which has been shown to lower blood pressure and prevent hypertension. Eating the recommended servings of dairy foods can lower blood pressure and is associated with a lower risk of developing high blood pressure.

Healthy weight

Studies have shown that dairy foods may favourably impact body composition and weight maintenance, particularly in overweight or obese adults who consume three servings of dairy foods daily while moderately reducing daily caloric intake.

Shortfall nutrients

Dairy foods play a vital role in building a diet that contains the nutrients Americans consistently do not consume enough of including calcium, potassium and magnesium. The most practical way to meet these nutrient recommendations may be to add an additional serving of dairy to the current daily recommendation.

The review has appeared in a supplement to the current issue of the Journal of the American College of Nutrition (JACN). (ANI)
