Vegetables

Vegetables dominate our rankings for a simple reason: our Nutrient Density Score measures nutrients per calorie, and most vegetables deliver a heavy load of vitamins, minerals, and beneficial compounds inside a very small energy budget. With a category median of 93 across 60 foods, this is the highest-scoring group we track. The standouts are leafy greens. Spinach, raw, Parsley, fresh, and Watercress, raw all reach a perfect 100, packing vitamin K, vitamin A precursors, folate, and potassium into roughly 20 to 30 calories per 100 grams.

What separates a 100 from a lower score is the ratio, not the raw nutrient count. Water-rich, low-starch vegetables score highest because their calories stay minimal while micronutrients stay dense. Scores dip toward the category floor for starchier items such as corn, peas, and potatoes, where carbohydrate calories dilute the per-calorie return, and for vegetables eaten in tiny portions.

How to choose

Lead with dark, leafy greens when you want the most nutrition per bite. Kale, raw at 99 and Beet greens, raw at 100 are excellent, versatile choices. Then round out variety with color, since different pigments track different nutrients. Note that individual needs vary, and people managing vitamin K intake or oxalates should weigh these choices accordingly. All figures reference USDA FoodData Central.
