Abstract

Background. Starch and dietary fibers as well as carbohydrates that are not digested and absorbed in the small intestine, are chemically heterogeneous components derived from plants consumed by humans. These chemical components undergo a full or partial fermentation process in the large intestine. Starch and other carbohydrates are the main sources of energy in all diets, while cell wall polysaccharides are the main components of dietary fiber.
Aim of the study. The role of starch and other carbohydrates in the human diet was analyzed in terms of structure and distribution in tissues, modification of these components during food processing and impact on functional properties in human nutrition and their behavior in the gastrointestinal tract.
Conclusion. Potato and other starch products can play a large role in the prevention of hyperglycemia if starch-derived glucose is released into the circulation in a very slow manner. Potato starch cultivars are therefore very important not only for the industry, but also in the human diet.
