Background. Dietary fiber is not only used for its nutritional properties, but also for its functional and technological properties. The food industry produces significant amounts of by-products which are problems in their disposal. Usually, these products are used in animal feeding. However, the high content of dietary fiber could permit their usage in food products. The dietary fiber in the diet has been recommended on the level 25-30 g/day. Thus, to supplement daily diet, dietary fiber should be incorporated into frequently consumed foods. The objective of this study was an effort to use raspberry pomace, byproduct of food processing, in cookies. Material and methods. The material of the study was raspberry pomace sourced directly from a fruit processing plant. Pomace is obtained in a dried form. Two sorts of raspberry pomace were applied: crumbled (ME) and non-crumbled (NM). These preparations were used as replacement of flour at the level 25 and 50%. The baked goods were sensory evaluated by a consumer method. Contents of neutral detergent dietary fibre (NDF) and its fractions were determined by the detergent method according to Van Soest and total dietary fibre (TDF), soluble dietary fibre (SDF) and insoluble dietary fibre (IDF) according to Asp et al. Results. The content of dietary fiber in raspberry pomace was very higher. These by- products were found to be rich in cellulose and lignin. Cookies with dietary fiber preparations contained much more dietary fiber - NDF (from 10.1 g/100 g - 25% NM to 24.7 g/100 g of products - 50% NM) in comparison with the control sample (1.7 g/100 g of product). The use of raspberry pomace in cookies resulted in fiber contents increase. Moreover, the addition did not have negative influence on organoleptic characteristics of the product and was accepted by consumers. Conclusions. The substantial dietary fiber content of fruit by-products and, in particular, fruit seeds, should attract the interest of dieticians.

Background. There has been an increase in the prevalence of overweight and obesity in adolescents and young adults, especially in men than women. Many adolescents have a sedentary lifestyle and consume more processed, low-fiber foods. Objective. The aim of this study was to assess the frequency of fiber intake and its selected dietary source consumption in relation to the overweight among Polish male students. Material and Methods. This cross-sectional study involved 1,233 male students aged 13.0-24.9 years from northern, eastern and central Poland. The respondents completed a self-administered Block Screening Questionnaire for Fruit/Vegetable/ Fiber Intake and measurements of their body mass and height were performed. The overweight and obesity prevalence was assessed using international standards. Results. The most frequently consumed foods by students included: white bread and potatoes, fruit and fruit or vegetable juices. The odds of overweight (including obesity) were lower from 28% (OR=0.72; 95%CI:0.56-0.93) to 31% (OR=0.69; 95%CI:0.50-0.95) with a daily consumption of white bread compared to non-daily consumption of white bread. Consumption ≥4 times/week of prepared vegetables (cooked, preserved or marinated) was associated with 51% lower odds of overweight (OR=0.49; 95%CI:0.27-0.97) compared to consumption less than 4 times/week of these foods. The odds of overweight for the level of fiber intake was insignificant. Conclusions. This study provides surprising insights regarding high-fiber and low-fiber food consumption and overweight in Polish male students. A lower odds of overweight was associated with a higher frequency consumption of relatively low in fiber foods as white bread and cooked, preserved or marinated vegetables. Most of the students consumed fiber at an unacceptable level, so a beneficial impact of high-fiber foods on overweight prevalence was not shown.
