Consuming carrots can significantly decrease the risk of cancer.
The methodology used in this research involved examining the links between carrot intake and the incidence of cancer. The scope was broad, examining all studies published before June 2022 that offered risk estimates connecting cancer incidence with either carrot consumption, α-carotene intake, or α-carotene plasma levels. Possible sources of such studies included those found via digital searches, manually identified within other studies, or garnered from existing reviews. Analysis was carried out comparing the highest and lowest reported intakes from prospective studies, estimating summary relative risks using a random-effects model.
The study's results indicated a strong correlation between carrot consumption and a notable reduction in cancer risk. This conclusion was derived from the analysis of 198 observational studies, 50 of which were prospective studies involving a total of 52,000 cases that specifically recorded carrot intake. Comparatively, on the correlation between α-carotene plasma levels and cancer risk, analysis from 30 prospective studies with 9,331 cases indicated that a higher presence of α-carotene also resulted in decreased cancer risk. Despite a moderate variance between studies, these findings serve as significant evidence in support of the anticancer benefits of carrots.

Regular consumption of raw carrots is associated with a significant, dose-dependent reduction in lung cancer incidence, suggesting a potential cancer-protective effect attributed to polyacetylenic compounds, particularly falcarinol and falcarindiol, present in raw carrots.

This research involved a long-term study of 55,756 Danish citizens over a period of more than 25 years. The focus was on investigating the relationship between regular consumption of raw carrots and the development of various cancers, predominantly adenocarcinomas and leukemia. The study assessed whether the frequency of carrot consumption influenced the incidence of lung, pancreatic, breast, prostate cancer, and leukemia. Additionally, it compared the effects of eating raw versus processed carrots.
The study found that eating raw carrots regularly was associated with a reduced occurrence of lung cancer. This link was less clear for pancreatic cancer and non-existent for breast and prostate cancer. The research suggested that the cancer-preventive properties of raw carrots could be attributed to specific compounds, namely falcarinol and falcarindiol. These compounds are not present in cooked carrots. This significant finding points towards the potential of raw carrots in cancer prevention, particularly for lung cancer.
