Consuming carrots can significantly decrease the risk of cancer.
2023 Critical Reviews in Food Science and Nutrition Carrot intake is consistently negatively associated with cancer incidence: A systematic review and meta-analysis of prospective observational studies Ojobor CC, O’Brien GM, Siervo M, Ogbonnaya C, Brandt K
Meta-Analysis Carrot
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.
Consuming chocolate with higher cocoa content can improve the nutritional status and functionality of older cancer patients in palliative care.
2022 BMC Palliative Care Effect of chocolate on older patients with cancer in palliative care: a randomised controlled study Vettori JC, da-Silva LG, Pfrimer K, Jordão AA, Louzada-Junior P, Moriguti JC, et al.
Clinical Study Cancer Treatment Support Chocolate Palliative Care
In the conducted study, 46 older cancer patients under palliative care were divided into three groups. The control group did not have a change in their diet (CG, 15 patients). The other two groups were given intervention foods—55% cocoa chocolate (IG1, 16 patients) and white chocolate (IG2, 15 patients)—for a duration of four weeks. The primary outcome was assessed based on changes in the patients' nutritional status, as measured by the Mini Nutritional Assessment tool. Other factors examined included food consumption, body measurements, body composition, laboratory parameters, and quality of life, using the European Organization for the Research and Treatment of Cancer instrument.
Discussion of the results revealed that the group consuming 55% cocoa chocolate showed an improvement in nutritional scores and functionality, as evidenced by the Mini Nutritional Assessment and the quality of life scores respectively. On the other hand, the group consuming white chocolate displayed decreased oxidative stress levels. However, body composition and anthropometric measurements remained largely unchanged across all three groups.
Plums, specifically European and Japanese species, exhibit anti-inflammatory and antioxidant properties that may be used for the treatment and prevention of cancer.
2022 Biomedicine & Pharmacotherapy Cancer protective effects of plums: A systematic review Bahrin AA, Moshawih S, Dhaliwal JS, Kanakal MM, Khan A, Lee KS, et al.
Systematic Review Anti-Inflammatory Antioxidant Plum
Methodology: The researchers conducted a systematic review of existing literature related to the effects of plums on cancer prevention and treatment. They used a variety of databases including Scopus, Google Scholar, PubMed, Medxriv, and the Cochrane Library, considering studies published from the inception of each database till July 2021. The validity of the studies was checked using the CONSORT checklist tool for quality assessment. A total of 6639 studies were initially scrutinized, narrowing down to 54 relevant studies for in-depth review.
Discussion of Results: The analysis of the chosen studies revealed high antioxidant content in plum extracts. While the majority of the research supporting these findings were conducted in vitro, a smaller quantity of clinical studies involved in vivo testing. The promising results gathered from these studies suggest the potential of plums being used both for treatment and preventing cancer, especially due to their antioxidative properties.
Ellagic acid, commonly found in various plant foods, can enhance cancer treatment by boosting the effects of chemotherapy and radiotherapy while reducing their side effects.
2022 Phytomedicine Synergism of ellagic acid in combination with radiotherapy and chemotherapy for cancer treatment Xue P, Zhang G, Zhang J, Ren L
Review Article Chemotherapy Ellagic Acid Pomegranate
The presented review compiled in vitro and in vivo experimental evidence of the synergistic effect of Ellagic acid (EA) in cancer therapy from multiple databases including PubMed, Web of Science, and Google Scholar. The focus was on the use of EA in conjunction with conservative treatment methods such as chemotherapy and radiotherapy.
The results suggest that EA, a polyphenolic compound found in various plant foods, has the potential to enhance the effectiveness of these treatment methods. It was found to improve treatment outcomes when combined with a low dosage of therapeutic drugs or optimized radiation levels. Additionally, EA appears to have a preventative effect against the adverse reactions normally associated with chemotherapy, possibly due to its antioxidant and anti-inflammatory properties. This makes it a promising candidate as a drug adjuvant in cancer treatment.
The literature overall supports an inverse association between green tea and cardiovascular disease-related health outcomes, while the included meta-analyses generally suggested an inverse association between green tea and BMI-related and blood pressure outcomes.
2020 European Journal of Clinical Nutrition Green tea and cancer and cardiometabolic diseases: a review of the current epidemiological evidence Abe SK, Inoue M
Systematic Review Endometrial Cancer Green Tea High Blood Pressure
The evidence on green tea consumption and health outcomes presented in this review suggests green tea may be favorable for cardiovascular disease, particularly stroke, and certain cancers such as endometrial, esophageal, lung, non-Hodgkins lymphoma, oral, and ovarian cancer. More evidence is needed to assess the impact of green tea on breast, gastric, and liver cancer risk. Additional studies could also help clarify the suggested null association with certain cancer sites: colorectal, pancreatic, and prostate cancer. Possible minor adverse events on health from green tea consumption were reported in one study, however these must be interpreted cautiously within the study context and possible finer dose-response implications. The findings for green tea and diabetes risk were inconclusive. For BMI the current evidence suggests a possible weak association, while the evidence is stronger supporting a decrease in blood pressure from green tea. More studies investigating a possible association between green tea consumption and other health outcomes such as cognition, injuries, respiratory disease would be informative to more completely assess the impact of green tea on human health.
In conclusion, our review suggests green tea may have health benefits especially for cardiovascular disease and certain cancer sites.
