Una dieta basada en plantes és una dieta que consisteix principalment o totalment en aliments d'origen vegetal.[1][2][3] Les dietes basades en plantes engloben una àmplia gamma de patrons dietètics que contenen quantitats baixes o nul·les de productes animals i grans quantitats de productes vegetals com ara verdures, fruites, cereals integrals, llegums, fruits secs i llavors.[4][5] No és indispensable que siguin vegans o vegetarians[6][7] però es defineixen en termes de baixa freqüència de consum d'aliments d'origen animal.[8][9]
