Abstract
ABSTRACTThe aim of the study was to investigate the satiety levels following the consumption of groats and to analyze the relationships between selected nutrients found in the groats. A total of 54 women were enrolled in a crossover, single-blind study. The participants tested five types of groats (a 240-kcal portion for 180 min). The highest satiety was determined for oat groats and barley groats. The correlation analysis indicated that the satiety of the examined groats was correlated to the highest extent with the content of dietary fiber and hydration degree. Studies showed that the key role in the regulation of satiety could be played by the presence of soluble dietary fiber (SDF). The results of the study indicated that all studied types of groats are a good source of high satiety food. Due to their high satiety value, groats should be used in the prevention and dietary treatment of people with excess body weight.

Energy balance is regulated by the frequency of meal intake, portion size, method of culinary preparation, and nutritional value, with the simultaneous energy expenditure.[1,2,3] A positive energy balance leads to the development of obesity
It is the opposite of appetite and hunger, in both physiological and psychological aspects. [7,8,9,10] Among the many food products with the greatest satiating potential, groats produced from various cereal species should be mentioned
Protein-rich diets were the subject of numerous studies which have demonstrated that the protein contained in foods may effectively contribute to a favorable energy balance and help to control body weight. [28,29] Groats, are not a rich source of protein
Summary
Energy balance is regulated by the frequency of meal intake, portion size, method of culinary preparation, and nutritional value, with the simultaneous energy expenditure.[1,2,3] A positive energy balance leads to the development of obesity. [11] The nutritional value of groats is very high They are a rich source of starch, protein, dietary fiber, as well as vitamin B, phosphorus, iron, zinc, and other essential ingredients. Groats were forgotten, yet recently their percentage in the diet has been steadily increasing, mainly due to their nutritional value. Water-soluble dietary fiber found in groats exhibits all functional properties of viscous and gel-forming food hydrocolloids. Thanks to these properties, it can increase the filling of the stomach, delay gastric emptying, and reduce the level of intestinal hormones involved in inducing the feeling of appetite and satiety. It can increase the filling of the stomach, delay gastric emptying, and reduce the level of intestinal hormones involved in inducing the feeling of appetite and satiety. [15,16,17,18,19,20]
