Ever wondered which foods are actually highest in iron, magnesium, or vitamin K? NutriRank answers that instantly. NutriRank searches the full USDA food database and ranks every food by how much of a nutrient it contains — so you can see, at a glance, the richest sources of anything you're looking for. WHY NUTRIRANK Pick any nutrient — vitamins, minerals, protein, fiber, amino acids, fatty acids and more See foods ranked highest to lowest by typical serving size Spot the food type at a glance with a category icon on every result Tap any food for a full nutrient breakdown with % Daily Value Switch between typical servings (1 cup, 1 oz) and 100 g — values update instantly PERSONALIZED TO YOU Daily Values aren't one-size-fits-all. NutriRank tailors %DV to your biological sex, age group, and pregnancy or lactation status using the NIH Dietary Reference Intakes — so the numbers reflect your actual needs. FILTER BY HOW YOU EAT Newly redesigned, compact filters make narrowing results effortless. Expand Filter by diet for Vegan, Vegetarian, Keto, or Paleo, or Filter by food group to pick from 16 groups — plus quick All Plants and All Animal shortcuts. Perfect for finding nutrient-dense foods that fit the way you eat. LEARN AS YOU GO Every nutrient includes a plain-English explainer of what it does in the body, plus key interactions (like vitamin D boosting calcium absorption). Each explainer links to authoritative sources — the NIH Office of Dietary Supplements, MedlinePlus, and USDA FoodData Central. MORE Save favorites and revisit recent searches Share your Top 10 foods for any nutrient Clean, fast, distraction-free design NutriRank is for anyone who wants to eat with intention — whether you're managing your nutrition, exploring a new diet, or just curious about what to eat more of.
