Only Certain Dairy Products Build Bone Strength
Studies have shown that the high calcium content of dairy products is beneficial for building better bone strength, but a new study claims that not all dairy products are equally beneficial. The study found that milk and yogurt strengthened bone mineral density (BMD), while cheese had no effect at all on BMD.
The study included 3,212 individuals who participated in the Framingham Offspring Study. They completed a food frequency questionnaire and then were followed for 12 years to record BMD measurements.
At the end of 12 years, the researchers analyzed the compiled data to determine the associations between dairy intake and BMD. They found that milk and fluid dairy were associated with higher BMD in the hip, but not the spine. Yogurt intake was associated with higher BMD in the femur. Cream and cream products such as ice cream appeared to have a negative effect on BMD in the femoral neck.
The study was conducted by researchers at the Institute for Aging Research (IFAR) at Hebrew Senior Life, which is an affiliate of Harvard Medical School. It was published online ahead of print on February 1, 2013 in Archives of Osteoporosis.
Dairy consumption has also been linked with bone health, diabetes prevention, weight loss, and improved mental function. If you’re looking to add more dairy to your diet, try to stick to the low-fat dairy products as the high fat content of “whole milk” products could reduce any positive benefits.
