They found that consuming more than recommended dietary allowance might benefit bone health.<\/em><\/strong><\/p>\n\n\n\n<p> The researchers argued that many protein intake recommendations by regulatory bodies around the world were established on non-bone health outcomes, and thus further research was needed to see how protein\u2014which makes up 50% of bone volume and one third of its mass\u2014can benefit bones. \u201cOver 53% of Americans over the age of 50 years have suboptimal bone health, greatly predisposing them to fractures,\u201d\u200b said report co-author Dr. Taylor Wallace of the Department of Nutrition and Food Studies at George Mason University. While systematic reviews of protein\u2019s impact on bone health have been written (and with mixed results), Dr. Wallace argued that this present report\u200b\u200b, published in the Journal of the American College of Nutrition, \u201cis the first systematic review of its kind that shows consuming protein above current recommended levels is beneficial for bone health.\u201d\u200b <\/p>\n\n\n\n<p><strong>Selecting the studies to review\u200b<\/strong><\/p>\n\n\n\n<p> The researchers collected randomized controlled trials and prospective cohort studies where the participants are healthy adults aged 18 and over. All studies had to look at the relationship between varying doses of protein at or above the current US recommended daily allowance (0.8g\/kg\/d, or 10%-15% of total caloric intake). Databases used were PubMed, Ovid Medline, and Agricola, and searching through the database lasted through April 2017. A total of 31 studies were chosen and included in the quantitative synthesis. <\/p>\n\n\n\n<p><strong>Fracture outcomes<\/strong><\/p>\n\n\n\n<p>Multiple studies in the analysis noted statistically significant improvements in bone mineral density on different parts of the body at varying periods of intervention (from as little as 35 weeks to 104 weeks) when participants consumed more than the recommended daily allowance of protein. However, there were also studies that saw no statistically significant change, leading the researchers to conclude, \u201cThough many studies reported BMD outcomes, there was large variability in the site measured.\u201d\u200b The researchers also found that there were not many studies that looked at fracture outcome. \u201cThe most convincing data come from an analysis of the Women\u2019s Health Initiative, where patients who consumed 20% higher calibrated protein intakes showed a significant decrease in the risk of forearm fractures,\u201d \u200bthey wrote. But the outcomes are still promising, they added. No existing literature suggests that there is an adverse effect on consuming protein above the recommended daily allowance to the bones. \u201cOur systematic review supports that protein intakes above the current RDA may have some beneficial role in preventing hip fractures and bone mineral density loss,\u201d \u200bthey added.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Though protein is
