Macronutrients chart definition and explanation

Macronutrient chart shows the content of protein, carbohydrates and fats in the food. These are the nutrients that give us energy. The most energy dense macronutrient is fat. It contains 9 calories per gram. Carbohydrates and Protein both contain 4 calories per gram. This chart also shows the quantity of water in the food. A lot of sources ignore the quantity of water in the food which clearly is wrong. Ignoring the water restricts us from seeing the real density of macronutrients in the food.
