Recent research from the University of Oxford in the United Kingdom finds that people who stick to vegan diets might have a higher risk of bone fractures compared to people who have meat in their diets. The risk may be higher for vegetarians and pescatarians, too.
For the study, a team of researchers analyzed data from about 55,000 men and women living in the United Kingdom who had agreed to participate in the Oxford component of the European Prospective Investigation into Cancer and Nutrition (EPIC) study to check how diets impact the risk of bone fracture.
Of these participants, around 30,000 ate meat, around 8,000 were pescatarians (ate fish), more than 15,000 were vegetarians, and about 2,000 were vegans at the time they started participating in the study between 1993 and 2001. The participants were followed for more than 17 years, on average.
The analysis of the received data showed that among the study participants eating a vegan diet, there were close to 20 more cases of fractures per 1,000 people over a 10-year period. In particular, vegans faced a higher risk of fractures of the hips and legs, as well as other main site fractures, such as the clavicle, ribs, and vertebrae.
A new study, published in the journal JAMA Network Open, suggests that increased consumption of vitamins B-6 and B-12 is associated with a higher risk of hip fracture.
For the study, the researchers analyzed data taken from 75,864 postmenopausal women who took part in the Nurses’ Health Study. The taken data related to health, data, supplements, recreational activities, medications, smoking habits, and BMI.
The analysis showed that the risk of hip fracture was the highest in women with a combined intake of both vitamins, exhibiting an almost 50% higher risk of the condition compared to the women with the low intake of both vitamins.
The authors write in their paper: “Although we acknowledge the limitations of our cohort design, the findings herein add to the body of literature that suggests caution should be used in vitamin supplementation when there is no apparent deficiency.”
A new study, published in the Journal of Endocrinology, suggests that excessive consumption of vitamin A may lead to the higher risk of weak and fracture bones.
In the study, a team of researchers from Sahlgrenska Academy at the University of Gothenburg investigated the influence of vitamin A doses equivalent to doses consumed by people taking supplements during long-time periods.
Dr Ulf Lerner, the lead researcher, comments: “Previous studies in rodents have shown that vitamin A decreases bone thickness but these studies were performed with very high doses of vitamin A, over a short period of time. In our study, we have shown that much lower concentrations of vitamin A, a range more relevant for humans, still decreases rodent bone thickness and strength.”
