As specialists in physiology, nutrition, public health, and endocrinology (hormones), the team sought to understand the role calcium and protein play in strengthening the bones of older people, even if these individuals were already working on their bone strength by consuming a sufficient amount of vitamin D.
To understand these calcium and protein amounts very simply, the control group received approximately two servings of dairy per day, while the experimental group received 3.5 servings.
Interestingly, the researchers conclude that the additional amounts of calcium and protein "was associated with a 33% reduction in risk of fractures of any type, a 46% reduction in risk of hip fractures, and an 11% reduction in risk of falls" when compared to the control group.
