Nutrients are substances that provide nourishment essential for the growth and maintenance of life. They are broadly classified into macronutrients, which are needed in large amounts, and micronutrients, which are required in smaller quantities.

Examples of macronutrients include carbohydrates, proteins, and fats. Carbohydrates, such as glucose and starch found in grains and fruits, are the body's primary source of energy. Proteins, like those in meat, dairy, and legumes, are crucial for building and repairing tissues and producing enzymes and hormones. Fats, found in oils, nuts, and fatty fish, provide energy, insulate the body, and protect organs.

Micronutrients include vitamins and minerals. Vitamins are organic compounds essential for various bodily functions. Examples include Vitamin C, found in citrus fruits and vegetables, which supports the immune system, and Vitamin D, often obtained from sunlight and fortified foods, important for bone health. Minerals are inorganic elements that play vital roles in processes like nerve function and fluid balance. Common examples are calcium, essential for strong bones and teeth, found in dairy products and leafy greens, and iron, vital for oxygen transport in the blood, present in red meat and spinach. Water, though not always classified as a nutrient, is essential for life and involved in numerous physiological processes.
