While some research has shown that vegan diets have positive health effects, such as lower risks of heart disease, diabetes and diverticular disease, our recent study also showed that vegans may have a higher risk of fractures, and vegans and vegetarians combined may have a higher risk of haemorrhagic stroke.

The mixed body of evidence makes it difficult to understand what the overall health impacts of vegan diets are. But why is the evidence so inconclusive?
