Carbohydrates are a primary source of energy for the body. When consumed, carbohydrates are broken down into glucose (blood sugar), which is the main fuel used by the body's cells, tissues, and organs to produce energy necessary for bodily functions and physical activity
. Specifically:
- Carbohydrates include sugars, starches, and fiber. Sugars and starches are converted into glucose, which is used immediately or stored in the liver and muscles for later energy needs
- Glucose from carbohydrates fuels cellular respiration, releasing energy by reacting with oxygen
- Complex carbohydrates (like starches in bread, rice, and potatoes) provide a slower, sustained release of energy, while simple sugars provide quick energy boosts
- Fiber, a type of carbohydrate, is not digested for energy but supports digestive health and helps regulate blood sugar
In summary, carbohydrates are the body's main energy source, supplying glucose that powers all cellular activities
