May protect against certain cancers

At least one-third of all cancers can be prevented by lifestyle choices, such as food, according to the World Health Organization. Vegans typically consume far more fruits, vegetables, and legumes than non-vegans. This may help to explain why a 2017 study suggested that vegans may have a 15% decreased chance of getting cancer.

As an example, consuming beans frequently may lower the risk of colorectal cancer by 9–18%. Additionally, eating more plant-based foods lowers your risk of developing various cancers, including stomach, lung, mouth, and throat cancers, according to the National Cancer Institute. Additionally, it might lower the risk of pancreatic, prostate, and colon cancer. Vegan diets typically include more soy products, which may provide some breast cancer protection. Avoiding specific animal products may also help lower the risk of colorectal, breast, stomach, and prostate cancers. It is believed that certain types of cancer are promoted by eating red meat, smoked meat, processed meats, and meats cooked at high temperatures.
