Carbohydrates provide a person with energy. People can also obtain energy from foods containing protein and fats, but carbohydrates are the body’s preferred source.
Carbohydrates break down into glucose in the body. Glucose moves from the bloodstream into the body’s cells with the help of the hormone insulin. All of the cells in a person’s body use glucose to function.
People get their carbohydrates from food. All plants contain carbohydrates, which typically represent a significant portion of people’s dietary intake.
Complex carbohydrates contain longer, more complex chains of sugars. They include oligosaccharides and polysaccharides. Complex carbohydrates also contain fiber and starch.
Refined carbohydrates are foods that have gone through processing that removes some of their ingredients, such as fiber and minerals.
Carbohydrates are essential for providing the body with energy and helping it function optimally. People may have varying requirements for carbohydrates according to their lifestyle, weight, and activity level.
