There are six major nutrients: Carbohydrates (CHO), Lipids (fats), Protein, Vitamins, Minerals, Water.

Answer 2: There are seven major classes of nutrients: carbohydrates, fats, dietary fiber, minerals, proteins, vitamins, and water.
Answer 3: Calcium:- Calcium is one of the most important minerals for the human body. It helps form and maintains healthy teeth and bones. A proper level of calcium in the body over a lifetime can help prevent osteoporosis.
Iron:- Iron is an essential element for blood production. About 70 percent of your body's iron is found in the red blood cells of your blood called hemoglobin and in muscle cells called myoglobin. Hemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues.
Iodine:- Iodine is a mineral found in some foods. The body needs iodine to make thyroid hormones. These hormones control the body's metabolism and many other important functions. The body also needs thyroid hormones for proper bone and brain development during pregnancy and infancy.
Sodium:- Sodium is both an electrolyte and mineral. It helps keep the water (the amount of fluid inside and outside the body's cells) and electrolyte balance of the body. Sodium is also important in how nerves and muscles work. Most of the sodium in the body (about 85%) is found in blood and lymph fluid.
