What is a food substance?

A food substance is a component or ingredient of food that provides nutritional value to the body. Food substances are typically classified into three main categories: macronutrients, micronutrients, and water.

Macronutrients are the three main nutrients that provide the body with energy and building blocks for growth and repair. They include carbohydrates, proteins, and fats.

Carbohydrates are the body's main source of energy. They are found in foods such as bread, pasta, rice, potatoes, fruits, and vegetables.

Proteins are essential for building and repairing tissues and muscles. They are found in foods such as meat, poultry, fish, eggs, dairy products, beans, and nuts.

Fats provide the body with energy and help to absorb vitamins and minerals. They are found in foods such as butter, margarine, oil, nuts, seeds, and avocados.

Micronutrients are essential nutrients that the body needs in smaller amounts. They include vitamins and minerals.

Vitamins are essential for a variety of bodily functions, such as growth, vision, and immunity. They are found in foods such as fruits, vegetables, and dairy products.

Minerals are also essential for a variety of bodily functions, such as bone health, muscle function, and fluid balance. They are found in foods such as meat, poultry, fish, dairy products, and vegetables.

Water is an essential nutrient for all living things. It is involved in many bodily functions, such as digestion, circulation, and temperature regulation. Water is found in foods and beverages such as milk, juice, soup, and water itself.

Food substances provide the body with the nutrients it needs to function properly. A healthy diet should include a variety of foods from all of the food substance groups.
