Calorie, Carbohydrate, Protein and Fat Calculator

Proteins, fats and carbohydrates make up the group of Macronutrients that provide us energy (measured in calories) needed by our bodies for growth, metabolism and other functions.  The prefix “macro” means large; macronutrients are needed in large quantities in contrast to micronutrients (vitamins and minerals).
Let us a briefly look at each of these macronutrients.
Calories: A calorie is a unit of energy. When you hear something contains 100 calories, it's a way of describing how much energy your body could get from eating or drinking it.
Carbohydrates: These are a major source of energy for our bodies and are stored in our muscles and liver.
Foods that contain large amounts of carbohydrates include fruits, grains (rice, oats, barley, etc) and roots (potatoes, yams, carrots, etc).
Carbohydrates provide 4 Calories of energy per gram.
Proteins:  Our bodies use proteins to grow tissue and muscle, repair organs and to create hormones and enzymes; proteins are also used for energy when carbohydrates are unavailable.
Foods that contain high levels of protein include poultry, fish, beans, diary, nuts and legumes.
Proteins provide 4 Calories of energy per gram.
Fats:  In order to absorb vitamins, our bodies need fats.
Foods that contain a high percentage of fat include cooking oils, butter, nuts and cheese. Ff the three macronutrients, fats contain the highest number of calories per gram.
Fats provide 9 Calories of energy per gram
