The development of diet quality indices requires researchers to make several methodological decisions, including selecting component parts (foods, food groups, nutrients, or substances like fiber or polyphenols), determining classification rules (e.g., whether potatoes count as vegetables or juice counts as fruit), and deciding whether to measure intake in absolute terms (grams) or relative terms (grams per 1000kcals).
