The Deal with Carbs

Carbohydrates are essential macronutrients found in various foods, providing energy and aiding digestion. They are chemically simple, consisting of carbon, hydrogen, and oxygen. Carbs are categorized into simple (monosaccharides and disaccharides) and complex (polysaccharides) forms. Glucose, a key monosaccharide, is vital for energy production through metabolism. Carbs are digested into simpler forms before entering the bloodstream. Excess glucose is stored as glycogen or converted to fat. Fiber, a type of carbohydrate, is crucial for digestive health and cholesterol management.
