Consuming carrots reduces the risk of gastric cancer by an indicated 26%.
Using specific search terms related to gastric cancer and carrot consumption, a comprehensive search through databases such as PubMed, Cochrane Library, Scopus, ScienceDirect, and some Persian databases was conducted. Comprehensive Meta Analysis/2.0 software was utilized for statistical analysis.
The initial search yielded 81 articles, but only 5 met the inclusion and exclusion criteria and were included in the study. Without mentioning specifics, a fixed effects model determined a significant reduction in the risk of gastric cancer associated with carrot consumption. The results showed no indication of publication bias through a funnel graph depiction. The results demonstrate an inverse relationship between carrot consumption and the risk of gastric cancer.

Carrot consumption, beyond its β- and α-carotene content, significantly reduces cancer risk, highlighting polyacetylenes as potential anti-cancer agents, urging active promotion of carrot intake.

Systematic Review Carotene Carrot
The study conducted a comprehensive search across various databases for studies published until June 9, 2022, exploring the relationship between carrot intake, α-carotene intake, α-carotene plasma concentration, and cancer incidence. Involving 198 observational studies, the systematic review identified 50 prospective studies (52,000 cases) linking carrot intake (directly or as α-carotene) to a substantial reduction in cancer risk (RR 0.90, 95% CI 0.87–0.94, P < 0.0001). Additionally, 30 prospective studies (91,331 cases) examining plasma α-carotene levels revealed a similarly significant risk reduction (RR 0.80, 95% CI 0.72–0.89, P < 0.0001), with moderate inter-study heterogeneity (I2 = 36% and 26%) and nonsignificant interaction with cancer types.
The findings emphasize the robust association between carrot consumption and decreased cancer risk, urging active encouragement of carrot intake. While α-carotene was used as a marker, the study suggests the need for further investigations into non-carotene-focused hypotheses to understand the underlying mechanisms of this association.
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.

Cohort Study Adenocarcinoma Cancer Carrot
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.

An umbrella review methodology was adopted to identify connections between carrot and carotene intake and various health outcomes. We turned to databases such as Web of Science, PubMed, and Embase to find the needed data. The analysis included the collected evidence from both interventional and observational studies that focused on carrots, carotene, and any related health impact. To estimate the summary effect size for each correlation, both random and fixed effects models were employed.
The study reviewed a total of 1329 studies and utilized the data from 30 meta-analyses with 26 health outcomes that fit the eligibility requirements. These featured outcomes related to various types of cancer, fractures, age-related cataract, sunburn, and Alzheimer's disease. The associations were analyzed between the health outcomes and the intake of carrots, intake of carotene, and serum carotene levels.
Crocin, a compound derived from saffron, has shown considerable potential in hindering tumor growth and improving immune status, across various malignant tumors.

Review Article Anti-Tumour Breast Cancer Cervical Cancer
The methodology for the study involved an in-depth review of modern pharmacological studies that have analyzed the therapeutic effects of crocin, a natural compound that can be extracted from saffron. Various anti-tumor effects were assessed including the induction of tumor cell death (apoptosis), restrictions on tumor cell proliferation, and potential barriers to invasion and metastasis of these cells. The potential for enhancement of sensitivity to chemotherapy and improvement of immune status were also examined.
Following the review, the study revealed that crocin has significant anti-tumor properties. It showed that this natural compound can induce apoptosis in tumor cells, inhibit their expansion and progression, and even prevent their invasiveness and metastasis. Furthermore, crocin demonstrated the potential to enhance the body’s responsiveness to chemotherapy and help boost the immune system. These effects were observed across a range of different malignant tumors, including stomach, liver, cervical, breast, and colorectal cancers.

Cohort Study Carrot Carrot Juice Coconut
In this experimental study, research was conducted using a pre-experimental research design with a two group comparison pre-test and post-test. The research population was compiled of teenage girls from a school in the City of Kediri. The investigators selected a sample of 32 respondents using purposive sampling methods, and utilized observation sheets and pain scale measurements from the Femoralis Rectus Sheath as their primary data collection tools.
The results of the study highlighted a significant difference in the effectiveness of the two tested interventions, young coconut water and carrot juice, for the alleviation of dysmenorrhea symptoms. In this comparison, it was found that young coconut water showed higher effectiveness in reducing the pain severity in teenage girls than carrot juice.
