Hard-to-digest carbohydrates (disaccharides) are carbohydrates that are not digestible by the human body; as a rule, we are talking about simple carbohydrates: starch. Lactose. Dietary fiber, etc. Also, in some cases, difficult-to-digest carbohydrates include complex carbohydrates: pectin and fiber.
Carbohydrates are organic compounds consisting of carbon, hydrogen and oxygen. Carbohydrates play an important role in the nutrition of humans and animals. They provide the body with the energy it needs to function.
One of the main functions of carbohydrates is to convert them into energy. This process occurs during the oxidation of carbohydrates to carbon dioxide and water.
Carbohydrates are divided into simple and complex. Simple carbohydrates are those that consist of one sugar molecule, such as glucose. Complex carbohydrates - contain more than one sugar molecule and are divided into starch and fiber.
Starch is a complex carbohydrate found in foods such as rice, potatoes and wheat. It has a high calorie content and is the main source of energy for the human body. Starch is poorly digested, which is why it is called a difficult-to-digest carbohydrate. When it is consumed, the body is not sufficiently saturated, that is, a person feels hungry for a long time. Due to this, eating starchy foods leads to excess weight gain.
