Warning: vegans face a 43% higher risk of bone fractures than meat eaters, warns a large British study.
The increased risk was not limited to vegans, who do not eat meat, fish, dairy products or eggs. Researchers have also identified a significantly higher risk of hip fractures among those who eat fish but not meat (pescatarians), and among vegetarians who swear both meat and fish, but consume dairy products and / or eggs.
The findings follow decades of dieting and the risk of fractures in around 55,000 Britons. All had enrolled in the EPIC-Oxford study between 1993 and 2001. (EPIC, or European Prospective Investigation Into Cancer and Nutrition, is one of the largest cohort studies in the world.)
For this review of diet and fracture risk, “we analyzed data collected over 18 years, on average, and found that vegans, vegetarians, and pescatarians had higher risks of hip fractures than those who did not. meat eaters, ”said senior author Tammy Tong, nutritional epidemiologist at the University of Oxford.
“[Hip fracture] the risk in vegans was 2.3 times higher than in people who ate meat, which equates to 15 more cases per 1000 people over 10 years, “she said.” In addition, vegans also had a higher risk of fractures all over the body, as well as broken legs and vertebrae compared to meat eaters. ”
Tong and his colleagues published their results online on November 22 in the newspaper. BMC Medicine.
Of the initial pool of 55,000 people, just over 29,000 were meat eaters (omnivores), about 8,000 were pescatarians, 15,500 were vegetarians, and nearly 2,000 were vegans.
The diets were evaluated when participants enrolled in the EPIC-Oxford study, and again in 2010. (Supplement intake was not evaluated.) Fracture risk was tracked through 2016 through to National Health Service records collected in England, Scotland and Wales.
During this period, more than 3,900 fractures occurred: 566 broken arms, 889 broken wrists, 945 broken hips, 366 broken legs, 520 broken ankles, and 467 fractures of other bones, including ribs, spine or clavicle .
