New review by International Osteoporosis Foundation (IOF) Nutrition Working Group examines role of nutrition in sarcopenia, with focus on protein, vitamins D and B, and acid-based diet.
Sarcopenia, or the gradual loss of muscle mass, is a common consequence of ageing, and poses a significant risk factor for disability in older adults. As muscle strength plays an important role in the tendency to fall, sarcopenia leads to an increased risk of fractures and other injuries.
The International Osteoporosis Foundation (IOF) Nutrition Working Group has published a new review which identifies nutritional factors that contribute to loss of muscle mass, or conversely, are beneficial to the maintenance of muscle mass. The Group reviewed evidence from worldwide studies on the role of nutrition in sarcopenia, specifically looking at protein, acid-"base balance, vitamin D/calcium, and other minor nutrients like B vitamins.
"The most obvious intervention against sarcopenia is exercise in the form of resistance training," said Professor Jean-Philippe Bonjour, co-author and Professor of Medicine at the Service of Bone Diseases, University of Geneva. "However, adequate nutritional intake and an optimal dietary acid-base balance are also very important elements of any strategy to preserve muscle mass and strength during ageing."
The review discusses and identifies the following important nutritional factors that have been shown to be beneficial to the maintenance of muscle mass and the treatment and prevention of sarcopenia:
As well, the Review discusses non-nutritional interventions such as hormones, and calls for more studies to identify the potential of antioxidants and anti-inflammatory compounds in the prevention of sarcopenia.
Dr. Ambrish Mithal, co-author and Chair and Head of Endocrinology and Diabetes division at Medanta, New Delhi underlined the need for further research in the field. "Strategies to reduce the numbers of falls and fractures within our ageing populations must include measures to prevent sarcopenia. At present, the available evidence suggests that combining resistance training with optimal nutritional status has a synergistic affect in preventing and treating sarcopenia, " said Mithal.
"We hope that further studies will shed light on other effective ways of preventing and treating this condition."
