What is nutrient density? A plain-English guide
A clear, data-grounded look at how much nutrition your calories are actually buying, and how to read a density score without misreading it.
FundamentalsCalories vs nutrient density: what the number really means
A calorie tells you how much energy a food carries, but not what that energy is worth, and confusing the two is the most common mistake people make reading a label.
FundamentalsHow to read the Percent Daily Value
The %DV column turns a wall of milligrams into a quick scorecard, but it stays silent on the calorie cost of nutrition. Here is how to read it well, and where our Nutrient Density Score picks up the slack.
FundamentalsHow to read a food label without getting fooled
The regulated Nutrition Facts panel tells you what a package is hiding, if you read it in the right order. Here is the one minute routine, plus the front-of-pack claims to ignore.
FundamentalsHow many calories are in a banana? Size chart included
The USDA answer for every banana size, from extra small to extra large, plus the sugar, potassium, and density score context that makes the number useful.
