Vegetarian Diet Linked to Lower Bone Density
Monday, July 27th, 2009Although there are undoubtedly many benefits to following a vegetarian diet, including staving off obesity, preventing heart disease and lowering your risk of certain types of cancers, a recent study found that people who follow vegetarian diets have slightly weaker bones when compared to those who consume meat.
The study, which was conducted in a joint effort between Australian and Vietnamese researchers, took a closer look at over 2,700 people. In the end, the researchers found that vegetarians had a bone density that was 5% less than that of those who eat meat. For vegans, the news was even worse, as their bone density was 6% weaker than those who eat meat. When it comes to ovolactovegarians, which are those who do not eat seafood or meat but who do include dairy and eggs in their diets, the bone density was almost the same as those who eat meat.
“The results suggest that vegetarian diets, particularly vegan diets, are associated with lower bone mineral density,” said lead researcher, Tuan Nguyen, in the report that he wrote for the American Journal of Clinical Nutrition. “But the magnitude of the association is clinically insignificant.”
Although the study determined that vegetarians and vegans have a lower bone density than meat eaters, the study did not look at whether or not the lower bone density puts vegans and vegetarians at a greater risk of experiencing bone fractures. According to Nguyen, this is certainly something that is worth exploring further.
“Given the rising number of vegetarians, roughly 5% in Western countries, and the widespread incidence of osteoporosis, the issue is worth resolving,” Nyguen continued.
Of course, the findings of this study are certainly no reason to give up the vegetarian lifestyle, as the benefits of following this type of diet far outweigh this possible downside. What it does mean, however, is that you should make an effort to make certain to include foods that are high in calcium within your diet. This way, you can enjoy the benefits of vegetarianism while also avoiding the possibility of experiencing a lower bone density.
