Choices calculator

International Choices 5-level criteria (2025 revision). Level 1 = healthiest, 5 = least healthy. The worst-scoring nutrient determines the level.

Assumptions: salt is converted to sodium (salt ÷ 2.5). For groups with only two thresholds (water, insects, other), above T2 = level 5. Values per 100 g (beverages: convert ml to g). Plant-based equivalence = protein threshold plus all but one micronutrient threshold, per 100 g (Smorenburg et al., Nutrients 2026, Table 5). Thresholds are the defaults from Table 5 and remain editable. This is a tool, not an official certification.
