Which type of carbohydrates includes starch and fiber?

Complex carbohydrates are those that consist of long chains of sugar molecules, which include starch and fiber. Starch is a carbohydrate made from many glucose units linked together, serving as a primary energy storage mechanism in plants. Fiber, on the other hand, is a type of carbohydrate that the body cannot digest, which plays a crucial role in digestive health by promoting regular bowel movements and helping to manage blood sugar levels.

In contrast, refined carbohydrates are those that have been stripped of their natural fiber and nutrients during processing, often leading to a quicker spike in blood sugar levels. Simple carbohydrates consist of basic sugars, such as glucose and fructose, which are quickly absorbed by the body but do not offer the same sustained energy or health benefits as complex carbohydrates. Processed carbohydrates can refer to the modifications made to carbohydrates during manufacture, which may include refined or simple carbohydrates but does not specifically highlight the beneficial aspects of starch and fiber found in complex carbohydrates. This distinction makes complex carbohydrates an essential part of a balanced diet.
