Nutrient Density
Nutrient density describes how many beneficial nutrients a food contains relative to its calories — nutrient-dense foods give you more vitamins, minerals and fibre per calorie.
Plain English
Patient-Friendly Explanation
Nutrient density is a way of describing how much goodness a food packs into each calorie. Vegetables, fruit, wholegrains, lean protein and legumes are nutrient-dense, while sugary drinks, sweets and fried snacks are not. Choosing nutrient-dense foods helps you get the vitamins and minerals your body needs while managing your weight.

Clinical Definition
Nutrient density refers to the concentration of essential nutrients (vitamins, minerals, protein, dietary fibre, fatty acids) per unit of energy in a food. Indices such as the Nutrient-Rich Foods (NRF) index score foods by the sum of beneficial nutrients relative to limiting nutrients such as saturated fat, added sugar and sodium. Diets high in nutrient-dense foods are associated with better micronutrient status and lower energy intake for the same volume of food, supporting weight management while reducing the risk of deficiency during caloric restriction.
Key Insight
Why It Matters
When you eat fewer calories, you can also eat fewer nutrients — choosing nutrient-dense foods protects against this. Dr Joseph Wang's weight management plans at Accord Medical emphasise food quality, not just calorie quantity.
