Bone loss is a critical health issue during space missions. Much in-flight and ground-based effort has been expended to understand and counteract this phenomenon. Although the more obvious countermeasures have been tested, with exercise and pharmaceutical therapies at the forefront, nutrition and dietary management has been largely untested. Some of the recent findings on exercise and pharmacotherapies, as well as ground-based data highlighting a few areas where nutrition has a clear effect on bone health, are reported in this review. One area highlighted here is the role of protein in acid-base balance and how this many affect bone during space flight. Finding a countermeasure for space flight-induced bone loss will benefit space travellers as well as help scientists better understand bone physiology in general, for the benefit of individuals with bone diseases and immobilised individuals.
