Indication: Colon cancer
Source: Intl J Cancer, 2004;110;110-116.
Research: Researchers compared dietary intake of carotenoids and other nutrients in 402 men and women diagnosed with colon cancer, as well as 688 healthy subjects who were matched for age, sex and city of residence (to reduce variables). They also investigated whether or not other dietary or lifestyle factors had an effect on the relationship between carotenoids and the risk of developing colon cancer.
Results: In the study population as a whole, there was no association found between carotenoids intake and risk of colon cancer. However, among specific groups, several patterns emerged in the study. Among people who had never smoked, high intake of beta-carotene was associated with a 56% lower risk of developing colon cancer. Among current and former smokers, high intake of lycopene was associated with a 37% lower risk of colon cancer. In addition, a high intake of lutein and zeaxanthin was associated with a 59-64% lower risk of colon cancer, but only among women who also consumed large amounts of omega 3 fats (from fish), such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
