Understanding Carbohydrates

Carbohydrates are essential macronutrients found in various foods, providing energy and aiding digestion. They exist as simple sugars and complex polysaccharides. Glucose, a key carbohydrate, is metabolized to produce ATP, the energy currency of cells. Carbohydrates are stored as glycogen, but excess is converted to fat. Fiber, a type of carbohydrate, is crucial for digestion and cholesterol management. While moderation is key, carbohydrates are vital for health.
