Another reason why a vegan diet boosts health

The correct acid-alkaline balance in the body is crucial for good health. A high acid load increases the risk of cardiovascular disease, type 2 diabetes, problems with muscles, joints and bones and kidney disease.

Acid-forming foods include meat and meat products, cheese, fish, eggs and processed wheat-based foods like white bread and pasta.

Animal foods, in particular, are abundant in sulphur-containing amino acids which generate acid-forming sulphate. Their content is two- to five-fold higher in meat and eggs than in grains and pulses, which are considered alkalising foods along with fruit and vegetables.

This trial compared the effects of a vegan diet with a meaty diet over four weeks in individuals consuming the same number of calories. Results showed that the vegan group had significantly lower levels of acid both in the diet and the body.

These findings are consistent with other intervention studies looking at the acid-lowering effects of plant-based diets. They conclude that a vegan diet may help reduce the dietary acid load, whereas a meat-rich diet substantially increases the burden.

About the author
Dr. Justine Butler
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.
