Nutritionist’s analysis: Regular consumption of carrots is related to a lower risk of cancer, but it is not evidence of direct cancer prevention.

There’s more to carrots than meets the eye! Nutritionist Lao Gu said that studies have shown that subjects who eat a certain amount of carrots every week are associated with a 20% reduction in cancer risk; diagram. (Picture taken from freepik)

[Health Channel/Comprehensive Report] Carrots not only help with eyesight health, but eating them right may also prevent the risk of cancer. Nutritionist Lao Gu said that a systematic review and comprehensive analysis of 50 prospective studies covering more than 50,000 cancer cases found that people who regularly eat carrots have a lower overall risk of cancer. The study also estimated that eating 80 grams each time, about 5 servings per week, is associated with a 20% reduction in cancer risk. However, he reminded that this study is an observational study and can only say that there is a correlation between the two. It does not directly prove that eating carrots can prevent cancer.

Lao Gu pointed out in a Facebook fan post that a systematic review and meta-analysis compared carrot intake and cancer risk and found that compared with people who eat less carrots, the overall cancer risk of regular carrot eaters is about 10% lower, and there is a dose-effect relationship, that is, the more you eat, the more obvious the association with lower cancer risk. Research even estimates that eating about 5 servings of carrots per week, 80g per serving, is associated with a 20% reduction in cancer risk.

However, Lao Gu said that although research shows that carrot intake is associated with a lower risk of cancer, don’t rush to supplement β-carotene health supplements. He mentioned that in the past, it was often believed that the health effects of carrots came from beta-carotene, but large clinical trials have not confirmed that beta-carotene supplementation can prevent cancer, and some high-dose supplements may even cause harm.

The researchers therefore proposed another possibility. The health effects brought by carrots may not necessarily come from a single component, but the comprehensive effect of other phytochemicals in the whole food. For example: Carrots contain a less discussed component called polyacetylenes, including falcarinol and falcarindiol. In cell and animal studies, these components are considered to be potentially related to inflammation regulation and cancer-related mechanisms.

Lao Gu emphasized that this study is mainly from a prospective observational study and can only be interpreted as "eating more carrots is associated with a lower risk of cancer." It does not directly prove that eating carrots has anti-cancer effects. More interventional studies are needed to confirm in the future.

Lao Gu reminded that carrots are definitely not an anti-cancer drug, but if you don’t eat enough vegetables, adding a serving of carrots to your plate is still a simple, cheap and healthy dietary choice worth accumulating in the long run.
