When assessing whether a particular food is beneficial for you or not, energy density vs nutrient density is an important consideration to make. In general, you should seek out nutrient density for health. Energy density Density is a physical property of matter that describes the relationship between mass and volume (density = mass / volume). However, when talking about energy density, we refer to energy (kilocalories or kilojoules) / volume. Therefore, energy dense foods are those that pack a lot of energy in a small volume. Energy dense foods are often high in fat (because fat is the macronutrient with the most energy per gram: 9 kilocalories or 37 kilojoules)…
