A Review Article published in 2023 in the journal PeerJ found that Crocin, a compound derived from saffron, has shown considerable potential in hindering tumor growth and improving immune status, across various malignant tumors. 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.

A Cohort Study published in 2022 in the journal Frontiers in Nutrition found that Moderate consumption of carrots is associated with a lower incidence of colorectal cancer, implying a potential cancer prevention effect in a certain dose-range. The research analysed the dietary intake of carrots/carotene and their relationship to colorectal cancer incidence and mortality in a cohort from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening. The study involved 101,680 participants who joined the cohort between November 1993 and July 2001. The hazard ratios were estimated through multivariable Cox regression analyses. Additionally, subgroup analyses and interaction tests were conducted to check for potential effect modifiers. A generalised additive model was used to examine the non-linear trend of the exposure to cancer-related outcomes. In total, the study documented 1,100 colorectal cancer cases and 443 cancer-related deaths. It was discovered that dietary carrot intake was linked to a 21% lower risk of colorectal cancer incidence for those in the 4th quintile group compared to the lowest quintile group. Increase in carrot intakes, on a per standard deviation, did not reveal any statistically significant associations with the disease incidence. There were no significant associations found between dietary α-, and β-carotene intake and colorectal cancer incidence, nor were there any associations between carrot/carotene intakes and cancer mortality. They also observed no non-linear dose-response relationships between dietary carrot, α-, and β-carotene intake and colorectal cancer incidence and mortality. Notably, the study found that smoking status could potentially modify the association of dietary carrot intake with incidence of colorectal cancer, but not mortality.

A Systematic Review published in 2020 in the journal Nutrients found that Ginger has been effective in a majority of studies, including those that examined the alleviation of nausea and vomiting of pregnancy, digestive function, improvement in the expression level of markers for colorectal cancer risk, and anti-inflammatory functions. Ginger is a natural spice that is used in diverse regions to add a pungent flavor to food. Furthermore, ginger has been used as an herbal medicine for common health problems. This systematic review is the first study that has exclusively collected RCTs regarding the efficiency of ginger in several human health conditions. The clinical effects of ginger have been introduced as six subsections: nausea and vomiting, gastrointestinal function, pain, inflammation, metabolic syndromes, and other symptoms. Reportedly, ginger has been effective in a majority of studies, including those that examined the alleviation of nausea and vomiting of pregnancy, digestive function, improvement in the expression level of markers for colorectal cancer risk, and anti-inflammatory functions. Several other functions have also been regarded as beneficial in trials, with some confronting results. However, a few drawbacks regarding the quality of the trials, inconsistent evaluation systems or parameters, and the generally small size of the studies need to be noted. Therefore, systematically designed research with detailed descriptions of methodology and a sufficient pool of participants is necessary for future clinical trials to address the functional characteristics of ginger.

A Cohort Study published in 2020 in the journal Nutrients found that Regular consumption of raw carrots, specifically 2-4 or more per week, is associated with a decreased risk of colorectal cancer. The methodology of the study involved examining the risk of being diagnosed with colorectal cancer in correlation with carrot intake in a Danish population of 57,053 individuals over a lengthy follow-up period. Self-reported intake of raw carrots was recorded, setting a baseline of 2-4 or more carrots each week as the metric for study. Results derived from this study show that individuals who consumed 2-4 or more raw carrots per week showed a decrease in the risk of colorectal cancer, as compared to individuals with no intake of the same. However, an intake of less than 2-4 carrots per week did not show a significant association with reduced colorectal cancer risk. Therefore, this supports the notion from previous studies that stated consumption of carrots could have a preventive effect against colorectal cancer.

A Cohort Study published in 2020 in the journal Evidence-Based Complementary and Alternative Medicine found that Traditional Chinese Medicine when combined with Western methods, could improve survival rates in patients with colorectal cancer. The study undertook a retrospective analysis of patients, newly diagnosed with colorectal cancer during 2004-2014, who were treated at Dalin Tzu Chi Hospital. With the help of the hospital's cancer registry database and medical records, patients were categorized into two groups: those who used Chinese Herbal Medicine (CHM) and those who did not. Survival rates between these groups were investigated with Kaplan-Meier analyses and Cox proportional hazards regression analyses. The research findings indicated a noticeable difference between the survival rates of the CHM users and the non-users. Furthermore, four specific CHM formulae - Jia Wei Xiao Yao San, Zhi Bah Di Huang Wan, Ping Wei San and Qui Pi Tang - were noted as significantly associated with enhanced survival. Therefore, it seems that integrating Chinese Herbal Medicine with Western treatment protocols could enhance survival in patients afflicted with colorectal cancer.

A Review Article published in 2019 in the journal Nutrition and Cancer found that Kiwifruit supplementation may be associated with direct and indirect anticancer effects, the former likely due to ascorbic acid-mediated reduction of DNA oxidative injury and cytotoxic effect on cancer cell lines. Overall, 58 items could be retrieved, fifty of which were excluded since they did not fulfilled all our search criteria. Eight studies (five in vitro studies, two human intervention trials, and one both in vivo and in human study) were finally included in this critical literature review. Taken together, the results of these published studies suggest that kiwifruit supplementation may be associated with direct and indirect anticancer effects, the former likely due to ascorbic acid-mediated reduction of DNA oxidative injury and cytotoxic effect on cancer cell lines, the latter more likely attributable to enhanced daily bowel movements and increased intestinal fecal content of lactic acid bacteria, which would finally contribute to lower the risk of malignancies, especially colorectal cancer.

A Systematic Review published in 2019 in the journal Nutrients found that Coffee consumption shows a protective effect against colorectal and colon cancers, particularly among US subjects and European men. A systematic review and meta-analysis of 26 prospective studies was conducted to explore the relationship between coffee consumption and the risk of colorectal cancer. The studies included in the review were appraised for their quality using the Newcastle-Ottawa Quality Assessment Scale for Cohort studies, with only one study deemed to be of low quality. The analysis was stratified by ethnicity to determine if this variable could explain the heterogeneity of the studies. In the discussion of the results, it was found that while coffee consumption didn't show a significant relationship with colorectal cancer overall, when stratified for ethnicity, a protective effect emerged in US subjects. This effect was especially pronounced when looking at colon cancer, with coffee showing a protective effect in men and women combined, and in men alone. When examined by ethnicity, there was a significant protective impact in European men and Asian women. However, there was no significant association found with rectal cancer. Decaffeinated coffee also exhibited a protective effect against colorectal cancer in both men and women combined.

A Systematic Review published in 2019 in the journal European Journal of Nutrition found that Consumption of chocolate shows a possible slight reduction in risk for coronary heart disease and stroke, with no association with other chronic diseases studied. Researchers analyzed information available up to July 2018 from PubMed, Embase, and Web of Science, focusing on prospective studies evaluating the correlation between chocolate intake and rates of all-cause mortality, coronary heart disease, stroke, heart failure, type 2 diabetes, colorectal cancer, and hypertension. Meta-analyses using random-effects models were performed, comparing highest and lowest intake categories, and applying linear and non-linear dose-response studies. The NutriGrade scoring system was utilized to assess the credibility of the evidence obtained. The study's findings were based on 27 identified investigations. It was discovered through linear dose-response meta-analyses that there were no associations of heart failure and type 2 diabetes with each 10 g/day increase in chocolate intake. A small inverse association was found for the risk of coronary heart disease and stroke with each 10 g/day increase in chocolate consumption. The credibility of the evidence was found to be either very low (for all-cause mortality, heart failure, type 2 diabetes, colorectal cancer, or hypertension) or low (for coronary heart disease, stroke).

A Systematic Review published in 2016 in the journal Acupuncture in Medicine found that We found low-to moderate-quality evidence for the efficacy and safety of acupuncture for recovery after surgery in colorectal cancer patients. Of 1225 screened hits, seven randomised trials with 540 participants were included. High or uncertain risk of bias and significant heterogeneity were observed. All outcomes were measured before discharge, and no trial explicitly reported post-discharge outcomes. The response to acupuncture in terms of postoperative symptoms was inconsistent across trials. QoL was not measured in the included studies. For certain outcomes reflecting physiological recovery, favourable effects of acupuncture were observed compared with sham acupuncture, namely time to first flatus and time to first defaecation. Two studies reported there were no acupuncture-related adverse events, whereas the remaining studies did not consider adverse events.
