Adding more fish to your diet might lower your risk of colorectal cancer, according to a new meta-analysis. The researchers reviewed 41 studies in which fish consumption had been recorded. People who ate the most fish were 20 percent less likely to be diagnosed with rectal cancer than those who ate the least. The investigators caution that the study does not show how much fish is enough and how it should be cooked.
