Abstract

Purpose of Review

Consumption of high-protein diets is increasingly popular due to the benefits of protein on preserving lean mass and controlling appetite and satiety. The paper is to review recent clinical research assessing dietary protein on calcium metabolism and bone health.

Recent Findings

Epidemiological studies show that long-term, high-protein intake is positively associated with bone mineral density and reduced risk of bone fracture incidence. Short-term interventional studies demonstrate that a high-protein diet does not negatively affect calcium homeostasis. Existing evidence supports that the negative effects of the acid load of protein on urinary calcium excretion are offset by the beneficial skeletal effects of high-protein intake.

Summary

Future research should focus on the role and the degree of contribution of other dietary and physiological factors, such as intake of fruits and vegetables, in reducing the acid load and further enhancing the anabolic effects of protein on the musculoskeletal system.

A diet high in meat protein and potential renal acid load increases fractional calcium absorption and urinary calcium excretion without affecting markers of bone resorption or formation in postmenopausal women. J Nutr. 2011;141(3):391–7. This randomized crossover controlled feeding study with postmenopausal women is unique in that two diets were designed to have a substantial difference in dietary acid load (81 mEq/day) and Ca absorption was measured by a sensitive whole-body scintillation counting of radio-labeled 47 Ca. The results show that a high-protein high-acid load diet increased fractional Ca absorption which compensates for increased urinary Ca excretion; it also increased IGF-1 and decreased PTH concentrations in the blood.

Appl Physiol Nutr Metab 2017;42(5):537-546. This recent study is worth mentioning in that the study reported detrimental effect of high-protein intake on bone. The conclusion was based on one bone resorption marker, C-telopeptide, which was increased in response to the high-protein intake. However, neither urinary calcium excretion nor dietary calcium absorption was measured, and in addition, serum concentrations of IGF-1, a bone anabolic agent, could have been increased by the protein intake had the sample size not been the issue.
