How This Page Is Made
Pages on EatAndAchieve combine USDA source data, site-specific scoring logic, and AI-assisted drafting, then receive human review for clarity and methodology. They are educational tools, not medical advice. Read more on the About page.
We analyzed all 63 spices and herbs in the USDA database and ranked them by overall nutritional density — factoring in protein, fiber, vitamins, and minerals relative to calories. All values are per 100g from USDA FoodData Central.
What is being ranked
These are category-specific foods scored for overall nutrient density, not just one headline vitamin or mineral.
Why calories matter
Foods score better when they deliver more useful nutrition for the calories they cost.
How to read it
Use the top of the list for reliable staples, then scan the tradeoffs before making a food a daily default.
What makes this category strong
Category spotlights are broader than nutrient posts. They reward foods that do several jobs well at once instead of winning one narrow metric.
Best for
Finding reliable staples inside one aisle of the grocery store.
Read the list this way
Higher-ranked foods usually combine better micronutrients, better fiber or protein, and a more reasonable calorie tradeoff.
How We Ranked
Each food was scored by adding up its contribution to 12 key daily values (protein, fiber, iron, calcium, potassium, vitamin A, C, D, magnesium, zinc, folate, and B12), capped at 100% each, then normalized by calories. This rewards foods that pack the most nutrition per calorie — true nutrient density.
