Ultra-processed food avoidance — people want to eat like it's 1940 but don't know how

Pain point

Belief that domestic food quality has collapsed; "food quality when I travel abroad is night and day." Counter-comments show the real blocker is knowledge/effort, not availability: "You can still make food at home from single ingredient sources."

Signal

Moderate-strong. ~8.5k upvotes with 1,483 + 626 + 325 + 314 on four separate food-quality comments — high comment engagement means genuine argument, not passive agreement. This is a recurring internet-wide theme (UPF, seed oils, additives), which raises confidence.

Opportunity

"NOVA-score meal planner" — scan-or-search app that scores groceries by processing level *and* then auto-generates a weekly shop + 20-min recipes using only 1-ingredient substitutes for your current cart. The gap Yuka leaves is the *replacement* step. Affiliate grocery revenue + $5/mo. **Feasibility: quick** (Open Food Facts API is free and open).
