Nutrients

Nutrients are substances that are essential for the growth, development, and maintenance of the human body. They are obtained from the food we eat and are necessary for various physiological functions such as energy production, tissue repair, and immune system function.

Types of Nutrients

There are six main types of nutrients:

1. Carbohydrates: Carbohydrates are the body's main source of energy. They are found in foods such as bread, rice, pasta, and fruits.
2. Proteins: Proteins are essential for the growth and repair of tissues. They are found in foods such as meat, fish, eggs, and legumes.
3. Fats: Fats are important for insulation, cushioning of organs, and energy storage. They are found in foods such as butter, oils, and nuts.
4. Vitamins: Vitamins are organic compounds that are essential for various metabolic processes. They are found in fruits, vegetables, and dairy products.
5. Minerals: Minerals are inorganic compounds that are necessary for the proper functioning of the body. They are found in foods such as meat, dairy products, and leafy green vegetables.
6. Water: Water is essential for various bodily functions such as digestion, nutrient transport, and temperature regulation. It is found in beverages and moisture-rich foods.
