Chapter: Major Nutrients of Foods Nutrients are essential components found in foods that provide nourishment to our bodies. They are vital for growth, energy, and overall health. In this chapter, we will explore the major nutrients found in foods. Carbohydrates: Carbohydrates are the body's main source of energy. Foods rich in carbohydrates include grains (such as rice, wheat, oats), fruits, vegetables, and legumes. Simple carbohydrates, like sugars, provide quick energy, while complex carbohydrates, like those found in whole grains, provide sustained energy. Proteins: Proteins are essential for the growth and repair of body tissues. Foods rich in protein include meat, poultry, fish, eggs, dairy products, legumes, nuts, and seeds. Proteins are made up of amino acids, which are often called the building blocks of life. Fats: Fats are another important source of energy and help in the absorption of certain vitamins. Foods rich in fats include oils, butter, nuts, seeds, avocados, and fatty fish. There are different types of fats, including saturated fats (found in animal products), unsaturated fats (found in plant-based foods), and trans fats (often found in processed foods). Vitamins: Vitamins are essential for various bodily functions, including immunity, vision, and bone health. There are two main types of vitamins: water-soluble vitamins (such as vitamin C and B vitamins) and fat-soluble vitamins (such as vitamins A, D, E, and K). Fruits, vegetables, dairy products, and fortified foods are good sources of vitamins. Minerals: Minerals are important for bone health, fluid balance, and nerve function. Common minerals include calcium, iron, potassium, magnesium, and zinc. Foods like dairy products, leafy greens, nuts, seeds, and whole grains are rich in minerals. Water: Water is crucial for hydration and helps in various bodily functions, including digestion and temperature regulation. It is essential to drink an adequate amount of water daily to maintain proper health and hydration. Understanding the major nutrients found in foods is essential for maintaining a balanced and nutritious diet. By including a variety of nutrient-rich foods in our meals, we can ensure that our bodies receive the necessary nutrients for optimal health and well-being.
