A recent study found that changing to an 'optimised vegan diet' could increase life expectancy by five to seven years for 40-year-old adults in seven different countries. The study looked at typical eating patterns in China, France, Germany, Iran, Norway, the UK, and the US, and determined that incorporating whole grains and pulses into a vegan diet could lead to significant health benefits.

Dr. Justine Butler, head of research at Viva!, highlights the importance of a vegan diet for health, the environment, and animal welfare. With a background in molecular biology, Dr. Butler emphasizes the scientific evidence supporting the benefits of a plant-based diet. By choosing a vegan lifestyle, individuals can live longer and prosper while also contributing to a more sustainable future for the planet.
