 Nutrition is the process by which living organisms obtain and utilize essential nutrients from food to support their growth, development, and overall health. Proper nutrition is crucial for maintaining physiological functions, preventing diseases, and promoting overall well-being.

Key Components of Nutrition:

1. Macronutrients: These are nutrients required in large quantities and provide energy for the body. The three main macronutrients are:a. Carbohydrates: Carbohydrates are the primary source of energy for the body. They are found in foods like grains, fruits, vegetables, and legumes.b. Proteins: Proteins are essential for tissue repair, growth, and maintaining the body's structure. Sources of protein include meat, fish, eggs, dairy, beans, and nuts.c. Fats: Fats are a concentrated source of energy and play a role in hormone production, cell membrane structure, and absorption of fat-soluble vitamins. Healthy sources of fats include avocados, nuts, seeds, and olive oil.

2. Micronutrients: These are nutrients required in smaller quantities but are essential for various physiological functions. The main micronutrients are:a. Vitamins: Vitamins are organic compounds that regulate various biochemical processes in the body. They are found in fruits, vegetables, whole grains, and animal products.b. Minerals: Minerals are inorganic elements vital for the proper functioning of enzymes and other physiological processes. Sources of minerals include fruits, vegetables, dairy products, and meat.

3. Water: Water is a fundamental nutrient that is essential for maintaining hydration, transporting nutrients, regulating body temperature, and supporting various bodily functions.
