Snacks

Snacks are one of the toughest categories to score well on nutrient density, and the numbers show it: the 60 foods here carry a median Nutrient Density Score of just 45 out of 100. Because our score is calculated per calorie, the usual snack-aisle formula of refined starch plus added fat plus salt gets penalized hard. Calories arrive fast, while fiber, protein, potassium, and micronutrients arrive slowly, if at all. The foods that climb the ranking do the opposite. They lean on a whole-food base, skip the deep fryer, and keep sodium in check.

That pattern explains the leaders. Sweet potato chips, unsalted top the category at 72, carrying the vitamin A and potassium of their root vegetable source. Air-popped popcorn lands at 63 because it is a whole grain with real fiber and almost no processing weight. Soy chips or crisps reach 58 on the strength of plant protein.

How to choose the better snack

Read for three things: an intact whole-food ingredient, minimal added fat, and lower sodium. Favor air-popped over microwave, unsalted over salted, and reduced-fat, unsalted chips over the standard fried version. Individual needs vary, and this is a reference, not dietary advice, but per calorie those swaps consistently move you up the scale.
