What are Carbohydrates (Carbs)
Carbohydrates are a major food source and a key form of energy for most organisms. carbohydrates are the body's main source of energy. They are called carbohydrates because, at the chemical level, they contain carbon, hydrogen, and oxygen. There are three macronutrients: carbohydrates, protein, and fats. Macronutrients are required by the body in large amounts and are essential for the proper functioning of the body. Macronutrients should be provided through diet as they cannot be produced within the body.
Types Of CarbohydratesThere are three main types of carbohydrates found in foods:-
- Monosaccharides are the simplest and smallest of carbohydrates. The blood sugar i.e. glucose is a monosaccharide. All carbohydrates eaten are digested down to glucose.
- Disaccharides are two monosaccharide molecules bonded together, for example, lactose( the milk sugar) maltose, and sucrose(table sugar).
- Polysaccharides are long chained monosaccharides. This chain can be branched or joined in a straight line. Glycogen and starches are polysaccharides of importance.
- are rapidly and easily digested, absorbed and metabolized in the body.
- are generally high in glycemic index
- Contain less or no fiber, as a result, they can make one feel hungry sooner.
- Examples include white bread, sugars, colas, refined flour, and its products and candies.
- Packed with fiber as a result promotes satiety and keeps you full for longer.
- healthier than simple carbohydrates.
- low in glycemic index and can be consumed by people with diabetes.
- Contain several nutrients especially micronutrients like vitamins and minerals
- Examples include- fruits, vegetables, pulses, and wholemeal pasta
