Researchers have found that people who follow a vegan diet have worse bone health than others.
The authors of the scientific work, which Naked Science writes briefly, wanted to determine the differences in the state of the bones of vegans and "omnivores", as well as to find nutritional biomarkers associated with bone health.
The study took place from January to July 2017. It involved 72 people aged 30-60 years with a body mass index of less than 30, without diabetes, cardiovascular disease, cancer and pregnancy. Half of the volunteers were vegan, meaning they did not eat animal products.
The study found that vegans took more dietary supplements, particularly vitamin B12. These people had lower bone ultrasound readings. In addition, they had decreased urinary calcium levels, zinc and selenoprotein concentrations, and a lack of total fatty acids.
"Scientific evidence suggests that some specific nutrients, derived primarily from animal food sources, are found in lesser amounts in vegans, which can adversely affect bone health," the scientists said.
