In concert with the acid-base literature, protein intake is considered to be a net acid-producing substance and thus a net negative risk factor for bone dissolution. However, substantial literature supports the beneficial effects on skeletal metabolism when higher protein levels are consumed in concert with adequate calcium, potassium, and other minerals, regardless of the source of protein (24–26). The Dietary Approaches to Stopping Hypertension (DASH) diet (27) is a calcium-rich diet that emphasizes fruits, vegetables, and low-fat dairy products. This diet underscores the importance of consuming a complement of foods from meats, grains, dairy, fruits, and vegetables as prudent for promoting optimal bone health. In the following articles, Rafferty and Lanham-New carefully review the evidence on the interaction of specific diet components that impact bone health and conclude that a balanced diet with recommended servings of dairy products and a variety of fruits and vegetables is prudent for optimal bone health. Additionally, they comment on future research directions for consideration by the scientific community.
