A significant UK study reveals that increasing calcium intake, equivalent to a glass of milk daily, may reduce the risk of bowel cancer by 17%. Researchers analyzed the diets of over half a million women over 16 years, finding that dark leafy greens, bread, and non-dairy calcium sources also offer protective benefits. Conversely, excessive alcohol and processed meat consumption heightens cancer risk. Experts recommend a balanced diet, maintaining a healthy weight, and quitting smoking to lower bowel cancer risks.
