A large study conducted by the University of Oxford found that adopting a meat-free diet can significantly reduce the risk of five types of cancer. The study included over 1.6 million meat-eaters and found that vegetarians had a lower risk of pancreatic, breast, prostate, kidney, and multiple myeloma cancer. However, vegans had a higher risk of bowel cancer compared to meat-eaters, though more research is needed to understand why.

The study suggests that meat-free diets, which are typically higher in fruits, vegetables, and fiber, are consistently linked with a lower risk of cancer. While some researchers argue that the difference in cancer risk may be due to meat consumption itself, additional research is required to fully understand the nuances of these findings. Overall, a well-planned plant-based diet, with necessary supplementation, can help individuals avoid nutritional deficiencies and potentially reduce their risk of developing certain types of cancer.
