This is a food-pattern shortlist, not a ranking of nationalities or a claim that one country causes better health.

1. 30% plant and whole-food emphasis: vegetables, fruit, beans, nuts, seeds, whole grains, and minimally processed foods.
2. 25% long-term dietary evidence: strength and consistency of research for the pattern, especially cardiovascular and metabolic outcomes.
3. 20% nutrient-dense staples: regular use of fish or legumes, unsaturated fats, fermented foods, and high-fiber staples.
4. 15% public-health guidance: alignment with local or regional dietary guidance and established nutrient reference values.
5. 10% practical cultural pattern: recognizable everyday foods that can be adapted rather than a short-lived diet trend.

The ordering is our transparent product rubric. It is not an official global health ranking. Your targets still use your age, body data, activity, goals, location, and preferences.
