Higher protein intake benefits bone health – Study

I have found that most people consider osteoporosis to be a women’s affliction. The reason is that statistics show two out of three women over the age of 50 will experience osteoporosis while only one out of three men will.  This is clearly a disease that affects more of us as we age. I think it is important for us men to keep in mind that while statistics show more women get it, the fact is, as women outlive men, there are simply more of them around. Osteoporosis is definitely something of which men should be aware.

A new expert consensus endorsed by the European Society for Clinical and Economical Aspects of Osteoporosis, Osteoarthritis, and Musculoskeletal Diseases (ESCEO) and the International Osteoporosis Foundation (IOF) has reviewed the benefits and safety of dietary protein for bone health, based on analyses of major research studies. The review, published in Osteoporosis International found that a protein-rich diet, provided there is adequate calcium intake, is in fact beneficial for adult bone health. It also found no evidence that acid load due to higher dietary protein intakes, whether of animal or vegetable origin, is damaging to bone health.

The key findings of the extensive literature review include:

Hip fracture risk is modestly decreased with higher dietary protein intakes, provided calcium intakes are adequate

Bone mineral density (BMD), which is an important determinant of bone strength, appears to be positively associated with dietary protein intakes

Protein and calcium combined in dairy products have beneficial effects on calciotropic hormones, bone turnover markers and BMD. The benefit of dietary proteins on bone outcomes seems to require adequate calcium intakes

There appears to be no direct evidence of osteoporosis progression, fragility fractures or altered bone strength with the acid load originating from a balanced diet.

Professor René Rizzoli, Professor at the Division of Bone Diseases of the Geneva University Hospitals and Faculty of Medicine, stated:

Adequate intake of dietary protein, together with calcium, is needed for optimal bone growth in children and the maintenance of healthy bone at all ages. This message needs to be reinforced in view of currently circulating myths suggesting that too much protein causes ‘acid load’ and is damaging to bone health. In fact, in the elderly, we find that a common problem is not too much protein, but too little. This review of the literature confirms that a balanced diet with sufficient protein intake, regardless whether of animal or vegetable source, clearly benefits bone health when accompanied by adequate calcium intake. This is particularly important for seniors with osteoporosis, and individuals at risk of malnutrition due to acute or chronic illness, or recovering from an injury.”

In seniors with osteoporosis, dietary protein intake above currently recommended levels may help to reduce bone loss and fracture risk, especially at the hip, provided calcium intakes are adequate.

Finally, besides increased protein intake, seniors need to keep in mind that weight-bearing exercise strengthens bones. A trip to the health club can protect your bones as well as build your muscles. Check out my posts on it:

And, last but not least, don’t forget that walking is weight-bearing exercise. Check out my Page – Why you should walk more for further details.

  1. Very interesting. I sometimes don’t eat a lot of protein.
