Nutrition is a method in which the food is consumed by the organisms into the body and utilizing the nutrients from the food.
Macronutrients are nutrients that people need in relatively large quantities. Proteins, carbohydrates, fat, vitamins, minerals, fibre, and water are all nutrients.
Sugar, starch, and fibre are carbohydrates.
- Sugars are simple carbs. The body quickly breaks down and absorbs sugars and processed starch.
- Fibre is also a carbohydrate. The body breaks down some fibre types and uses them for energy; others are metabolized by gut bacteria, while other types pass through the body.
- Fibre and unprocessed starch are complex carbs. It takes the body some time to break down and absorb complex carbs.
Proteins consist of amino acids, which are organic compounds that occur naturally. Some foods provide complete protein, which means they contain all the essential amino acids the body needs. Other foods contain various combinations of amino acids.
