Because of their role as antioxidants, the intake of carotenoids has been hypothesized to reduce the risk of head and neck cancer (HNC). We conducted a systematic review and meta-analysis of the epidemiological studies to investigate whether the intake of specific carotenoids from dietary sources, as well as combined carotenoids, is associated with the risk of HNC according to cancer subsites. A comprehensive literature search of the Medline and Scopus databases was conducted. Sixteen articles…

Carotenoid intake from natural sources and colorectal cancer: a systematic review and meta-analysis of epidemiological studies

Overall, the findings do not support a significant association between intake of specific carotenoids from dietary sources, as well as combined carOTenoids, and the risk of CRC overall and by anatomic subsite.

Dietary Carotenoids in Head and Neck Cancer—Molecular and Clinical Implications

Recent epidemiological, key opinion-forming systematic reviews, cross-sectional, longitudinal, prospective, and interventional studies based on in vitro and animal models of HNC indicate that high carotenoid content obtained from daily supplementation has positive effects on the initiation, promotion, and progression of H NC.

Fish/shellfish intake and the risk of head and neck cancer

Patients whose fish/shellfish intake was among the highest tertile had a 20% lower odds of SCCHN compared with those in the lowest tertile, and the inverse association was more pronounced for oral cavity and oropharyngeal tumors, for African Americans, and for females.

Inflammatory potential of diet and risk of oral and pharyngeal cancer in a large case‐control study from Italy

The results indicate that the pro‐inflammatory potential of the diet, as shown by higher DII scores, is associated with higher odds of oral and pharyngeal cancer.

The Potential of Phytochemicals in Oral Cancer Prevention and Therapy: A Review of the Evidence

An overview of oral cancer including the etiological factors, diagnosis, and traditional therapy is provided and the classification, dietary sources, anticancer bioactivity, delivery system improvements, and molecular mechanisms against oral cancer of phytochemicals are discussed.

The protective role of Vit C and Vit C-containing foods in head and neck cancer

It is indicated that a low level of Vit C consumption is associated with a high risk of HNC, suggesting that Vit C and Vit C-containing foods display potential protective effects against HNC.

Should We ‘Eat a Rainbow’? An Umbrella Review of the Health Effects of Colorful Bioactive Pigments in Fruits and Vegetables

Health outcomes associated with multiple color pigments were body weight, lipid profile, inflammation, cardiovascular disease, mortality, type 2 diabetes and cancer, and findings show that color-associated FV variety may confer additional benefits to population health beyond total FV intake.

Role of Nutrition in Oral and Pharyngeal Cancers: From Etiology to Prevention

Dietary factors linked to increased risk of OPC include consumption of red meats and saturated fats, whereas other dietary factors were linked to reduced risk including consumption of fruits and vegetables, legumes, unsaturated fats, adequate intakes of vitamins and minerals, and dietary intake of bioactive phytochemicals.



Vitamin A and risk of cervical cancer: a meta-analysis.

Intake of specific carotenoids and risk of lung cancer in 2 prospective US cohorts.

Data from 2 cohort studies suggest that several carotenoids may reduce the risk of lung cancer.

Effect of dietary antioxidants and risk of oral, pharyngeal and laryngeal squamous cell carcinoma according to smoking and drinking habits

Dietary antioxidant intake prevents head and neck squamous cell carcinoma in smokers and drinkers, and the protective effect of these antioxidants was seen in both men and women.

ß-Carotene and Lung Cancer in Smokers: Review of Hypotheses and Status of Research

Human and animal studies have shown that specific circumstances, among them heavy smoking, seem to influence the effect of high β-carotene intakes, and in normal, healthy, nonsmoking populations, there is evidence of beneficial effects.

The effect of vitamin E and beta carotene on the incidence of lung cancer and other cancers in male smokers.

No reduction in the incidence of lung cancer among male smokers is found after five to eight years of dietary supplementation with alpha-tocopherol or beta carotene, and this trial raises the possibility that these supplements may actually have harmful as well as beneficial effects.

Diet and oral cancer - a case control study.

The results of the study suggest that poor dietary intake of vegetables and fruits coupled with low estimated intake of betacarotene, thiamine, riboflavin, folate, vitamin C, iron and copper, modify the risk potential of oral and oropharyngeal cancers.

Carotene intake and the risk of laryngeal cancer in coastal Texas.

A significant inverse association (odds ratio) was found between low carotene intake and the risk of laryngeal cancer, but no association was found with total vitamin A or retinol intake.

Retinol, antioxidant vitamins, and cancers of the upper digestive tract in a prospective cohort study of postmenopausal women.

Evidence is provided that higher intake of antioxidant vitamins may be important in the prevention of cancers of the upper digestive organs and the dose-response relation between gastric cancer risk and intake of carotene was clear and statistically significant.

Diet and pharyngeal cancer

The results of this study suggest that intake of vitamin C may be protective against pharyngeal cancer, and are consistent with the results of previous studies which reported a decreased risk of pharynGEal cancer associated with intake of fruits and vegetables.

Dietary factors in oral and pharyngeal cancer.

There was an inverse relationship between fruit intake and risk of oral and pharyngeal cancer; individuals in the highest quartile of intake had about half the risk of those in the lowest quartile.
