1) Carbohydrate: Carbohydrates are the sugars, starches and fibres found in fruits, grains, vegetables and milk products as well; they are of three types: polysaccharides, disaccharides and oligosaccharides. Though often maligned in trendy diet, carbohydrates are one of the basic food groups that are important to a healthy diet like curd etc. and these all needs to be digested.
2) Protein: Proteins are the macronutrient that are essential for building muscles. It is mostly found in animal products and is also present in other sources like nuts and pulses etc. Protein of the ingested food are broken down to the amino acids by the peptidase enzyme. It plays various roles in your body like repair and building of body tissues, allows metabolic reactions to take place and coordinates body functions.
3) Fats: Fats are nutrients that provides energy. Fats contains 9 calories in each gram. It help in the absorption of fat soluble vitamins A, D, E, and K; and their ingested foods are triglycerides. Fats are either saturated or unsaturated and they are digested by lipases enzyme.
