Are anti-inflammatory foods associated with a protective effect for cutaneous melanoma
The aim of this systematic narrative review is to answer the following research question: are anti-inflammatory foods or food components associated with a protective effect for melanoma development? Following the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline, a systematic review was conducted. All cohort studies (n = 18) so far on diet and cutaneous melanoma were reviewed. Out of the 18 cohort studies, seven investigated the role of coffee on melanoma and six studies found a protective effect. Food components considered as anti-inflammatory, such as vitamin D, vitamin A, folic acid, niacin, vitamin C, omega-3 fatty acids, and carotenoids (β-carotene, lutein, zeaxanthin, and lycopene), were not associated with a protective effect for melanoma. Other anti-inflammatory food items, such as tea, fruits, and vegetables, except for citrus fruits that were borderline associated with an increased risk, were not associated with cutaneous melanoma. In conclusion, the only anti-inflammatory food item that was consistently associated with a protective effect for cutaneous was coffee in particular caffeinated coffee.
