Natural compounds that we consume in a diet composed of vegetarian products and fruits regulate oxidative stress through the KEAP1/Nrf2 signaling pathway and are important in the prevention and treatment of cancer; examples include resveratrol, curcumin, sulforaphane, quercetin, phenethyl isothiocyanate, epigallocatechin gallate, hesperidin and 2′-hydroxyflavanone [72,73,74,75,76,77,78]. Here, KEAP1 is linked to cancer.
