Asthma and diet

A healthy vegan diet may combat asthma

A review of current evidence looking at the links between diet and asthma in children and adults found that diets rich in fruits, vegetables, grains and pulses, with little or no animal products, may reduce the risk of asthma. Antioxidants, fibre, vitamin D, saturated and polyunsaturated fats are all likely, they say, to affect how asthma might develop. Plant foods may protect against asthma via their effects on inflammation, oxidation and microbial composition – it’s that microbiome again! Additionally, increased fruit and veg, reduced animal products and weight management could mediate free radical damage, cytokine release and other immune responses involved in the development and course of asthma.

Clinical trials identifying the mechanisms involved could lead to the potential use of nutritional therapy in the prevention and management of asthma.

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.
