Every chemical process in the body is dependent on our consumption of food, water, and air. Since this is true, paying attention to what we eat is essential for good health. There is very little disagreement about what a healthy diet really is. A wholefood plant-based vegan diet is the daily fare of the healthiest and longest-living people on the planet.

There is also no disagreement about what the modern diet laced with cheap food is doing – it is killing us. Eating a poor-quality diet high in cheap food is linked to a higher risk of obesity, depression, digestive issues, heart disease and stroke, type 2 diabetes, cancer, and early death. And as you might expect, this tsunami of disease puts incredible pressure on an already struggling NHS.
