Previous studies show that high intakes of animal protein can lead to bone loss. This five-year study in the British Journal of Nutrition looked at the diets of 757 girls in Beijing, China. Some of the group were given cow’s milk for the first two years. Results showed that while calcium intake improved bone health, animal protein (especially from meat and eggs) reduced bone density. Plant protein did not have this harmful effect.

I joined Viva! as a health campaigner in 2005 after graduating from Bristol University with a PhD in molecular biology. My scientific training helped me research and write numerous reports, guides and fact sheets for Viva! including Meat the Truth, Fish-Free for Life, One in Nine (breast cancer and diet) and the substantial report on the detrimental health effects of consuming dairy; White Lies. This accompanied Viva!’s report The Dark Side of Dairy which spelt out the inherent cruelty of dairy farming. We were the first UK group to take on the dairy industry in this way, and many of our supporters go vegan after reading these reports. Click here for more info.
