1. Defining Carbohydrates: The Body’s Fuel Source
Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen atoms. They are primarily found in plant-based foods and dairy products. When consumed, your body breaks down carbohydrates into glucose, also known as blood sugar, which is the primary fuel for your cells, tissues, and organs. Glucose can be used immediately for energy or stored in the liver and muscles as glycogen for later use.
1.1. The Role of Glucose
Glucose is the cornerstone of carbohydrate metabolism. According to a study published in the American Journal of Clinical Nutrition, glucose is essential for brain function, muscle activity, and overall energy levels. A consistent supply of glucose ensures that your body operates efficiently, supporting everything from cognitive processes to physical endurance.
