The effect of meat marinating with aqueous extract of Ilex meserveae dried leaves on dry-aged beef quality was investigated. Shear force, TBARS value, color parameters, fatty acid profile, and sensory properties were evaluated in beef cuts dry-aged for 21 days. The use of Ilex meserveae dried leaves as marinade at 0.5, 1.0, and 2.0%

did not affect the shear force and color parameters of dry-aged beef. The marinating of beef cuts with Ilex meserveae resulted in efficient prevention of lipid oxidation without impairing sensory acceptability. Aqueous extract Ilex meserveae can be applied as a natural ingredient in meat marinade to prevent peroxidation.
The aim of the study was to evaluate the glycaemic indices (GI) and glycaemic loads (GL) of four food dishes made from yeast dough (steamed dumplings served with yoghurt, apple pancakes sprinkled with sugar powder, rolls with cheese and waffles with sugar powder), based on their traditional and modified recipes. Modification of the yeast dough recipe consisted of replacing wheat flour (type 500) with whole-wheat flour (type 2000). Energy value and the composition of basic nutrients were assessed for every tested dish. The study was conducted on 50 people with an average age of 21.7 ± 1.1 years, and an average body mass index of 21.2 ± 2.0 kg/m2. The GI of the analysed food products depended on the total carbohydrate content, dietary fibre content, water content, and energy value. Modification of yeast food products by replacing wheat flour (type 500) with whole-wheat flour (type 2000) contributed to the reduction of their GI and GL values, respectively.
The supply of carbohydrates, contained in food products and meals, to the organism causes an increase of glucose in blood, which is referred as “glycemic effect”. The concentration of glucose in blood increases after eating each meal and usually reaches its maximum after 20–30 min after food consumption, and then is gradually reduced. It returns to the level of fasting within 1–2 hours. However this pattern shows some individual variation.The increase of interest of the glycemic index and glycemic load of food products came through the interconnection of these indicators of noncommunicable chronic diseases like diabetes, cardiovascular disease, cancer, overweight and obesity.
Background. A recently growing number of children and adolescents with overweight or obesity is indicative of the need for diagnosing their complications that may appear in the early childhood. For this reason, diagnostic criteria were developed for components of the metabolic syndrome (MS) also for these groups of the population. Objective. This study was aimed at evaluating the frequency of metabolic syndrome risk factors occurrence in children and adolescents from the city of Wrocław and surroundings depending on gender, age and physical activity. Material and methods. Investigations on the frequency of occurrence of dietary and non-dietary risk factors of the metabolic syndrome were carried out in the years 2010-2017 among 771 children and adolescents aged 10-18 year, attending to primary schools, gymnasiums and secondary schools in Wrocław. Results. The lack of any components of the metabolic syndrome was demonstrated in 14.78% of the children aged 10-12 years as well as in 17.38% of both adolescents aged 13-15 and 17-18 years. One risk factor was most frequently diagnosed in children aged 10-12 years (17.89%) and it was arterial hypertension (16.08% of the whole surveyed population). Three MS components were demonstrated in 15 persons (1.95% of the whole surveyed population), including in 7 girls and 8 boys. The persons with three MS risk factors from the age category 13-15 years constituted 0.26% whereas these from the age category 17-18 years constituted 1.69% of the whole surveyed group. Conclusions. It shall be concluded that the incidence of the fully symptomatic MS depended significantly on the age of the surveyed, but not on their gender. Among the three adopted components of MS, the most frequently demonstrated disorders included: arterial hypertension, abdominal obesity and increased concentration of triglycerides in blood serum.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
