Recent research from Japan suggests that eliminating meat and dairy from one's diet may actually increase the risk of developing tumors associated with colon cancer. In studies conducted on mice with genetic mutations similar to familial adenomatous polyposis, those on a normal diet that included meat and milk proteins showed fewer tumors in the small intestine compared to those on a plant-based diet. Furthermore, the introduction of albumin, a protein found in meat, to a protein-free diet yielded similar tumor-suppressing effects. The findings underscore the importance of dietary proteins for maintaining a healthy immune system, as mice on plant-based diets exhibited lower levels of T cells in their small intestine. As the incidence of colorectal cancer continues to rise, experts emphasize the need for public awareness regarding dietary choices and cancer prevention strategies.
