A Vegan Diet Could Save You Money Now and in the Future!

When comparing three diets for insulin-dependent type 2 diabetes, a whole food, plant-based diet cost just $9.78 per day. This was 38% less than the control diet, and 23% less than the DASH diet, which includes low-fat dairy, fish, and poultry.1 When participants ate the plant-based diet, they also had lower insulin requirements and improved insulin sensitivity, which could reduce their long-term health care costs.2

An analysis the Physicians Committee published last year found that food costs decrease 16% on a low-fat vegan diet, a savings of more than $500 a year, compared to a diet that includes meat, dairy, and other animal products.3
