    The aim of the study was to evaluate the effect of a short-term consumption (six weeks) of gluten-free bakery products on the anthropometric parameters. The study group was composed of volunteers from the general population and consisted of 30 healthy adults. The amount of bakery product was determined as follows: women consumed 150 - 200 grams per day; men 200 - 250 grams per day. Anthropometric measurements were made by using InBody 720, we received data such as body weight, Body Mass Index (BMI) and Waist-to-Hip Ratio (WHR), which we evaluated the presence of overweight and obesity in the monitored groups. We also observed visceral fat area (VFA). We found out that the 6-week consumption of gluten-free bread and bakery products showed a significant reduction in body weight and BMI (p <0.01), but also to a significant increase in VFA (p <0.05). By the impact of consumption we recorded the increase of body weight and BMI in 70% of participants (in 30% there was slight increase), decrease of WHR in 33% (increase in 43%) and decrease of VFA in 43% (increase in 57%). For other participants, the values remained unchanged. Two months after the termination of the consumption of gluten-free products we found out the increase of body weight and BMI, WHR remained unchanged, however in the case of VFA showed significant increase of values. We can summarize that dietary habits play a crucial role in the development of overweight and obesity and the consumption of bread and bakery products can also affect it. However, the overall effect of bread and bakery consumption on the development of overweight depends on many factors, such as the composition of the bread and bakery products and the presence of gluten

    In the first stage of our research we found out a higher content of selenium in the meat of calves of experimental group (with added the organic form of selenium to the feed mixture) compared to control group (fed without organic form of selenium). In the second stage of our research we focused on monitoring the impact of selenium enriched veal meat and on selenium concentration in blood serum and the selected biochemical parameters of lipid spectrum of the experimental group of volunteers. Ten people who were participating in the research were at the age range between 29 - 56 years. All the volunteers consumed veal meat enriched with organic selenium for 4 weeks. Before starting the experiment we took venous blood of the volunteers and this blood was considered as a control sample of selenium in blood serum of the experimental group. Selenium concentration in blood serum of the examined group was determined by an average of 58.31 ±5.36 mg.L.-1 and none of them reached the optimal level of selenium. Consequently, we carried out the additional blood sampling after 2 and 4 weeks of the consumption of veal meat. There was registered a slight increasing of selenium status, whereas after the finishing the consumption, we determined the average selenium concentration in blood serum of the experimental group 60.73 ±4.05 mg.L-1. The evaluation of lipid profile of the experimental group showed (after input blood sampling) higher values of total cholesterol level and lower levels of HDL cholesterol. This fact shows the higher risk of starting the cardiovascular diseases. Reported research results didn't show statistically significant changes of blood lipid spectrum of the experimental group. We concluded that the consumption of supplemented veal meat can positively affect the level of selenium in our body and thereby increase it can increase the protective effect against the influence of free radicals

    The distribution of fat in different areas of the body is important since accumulation of fat within the abdominal cavity represents a much more severe cardiovascular risk than accumulation in subcutaneous adipose tissues. Apricot seeds contain a wide variety of bioactive compounds and that consumption can decrease blood pressure and total blood cholesterol levels, fight oxidative stress and maintain body weight. The aim of the study was to analyse body composition: body fat mass (BFM), fat free mass (FFM), skeletal muscle mass (SMM), body fat percentage (%BFM), visceral fat area (VFA), total body water (TBW) - intracellular water (ICW) and extracellular water (ECW) and to evaluate the changes that occur after 6-weeks consumption of bitter apricot seeds. The study group finally consisted of 34 healthy adults volunteers (21 females and 13 males). Volunteers were recruited from the general population of Slovakia. Respondents were 23 - 65 years old, where the average age of women was 40.65 ±11.31 years and the average age of men was 36.91 ±9.98 years. All participants were asked to consume 60 mg.kg-1 of body weight of bitter apricot seeds daily during 6 weeks. Body composition was diagnosed by multi-frequency bioelectrical impedance analysis (MFBIA) by InBody 720 (Biospace Co., Korea), which measures the total impedance at frequencies of 1, 5, 50, 100, 500, 1000 kHz. At baseline mean body weight was 85.78 ±14.66 and 62.84 ±12.19 kg in the male and female participants, respectively. After 6 weeks of consumation we observed non-significant decreasing of mean body weight. The mean BFM was 19.25 ±8.81 kg in the male group and 19.47 ±7.21 kg in the female group. After six weeks, BFM decreased non-significantly (on average 0.5 kg) in both groups. The mean FFM at baseline was 43.37 ±5.98 and 66.54 ±7.98 kg in the female and male participants, respectively. The statistical analysis confirmed that the increase of FFM (43.37 ±5.98 kg to 43.56 ±5.80 kg) in the female were statistically significant (p <0.05). VFA was greater in the men (82.04 ±39.82 cm2 at baseline and 78.65 ±39.79 cm2 after 6 weeks) comparison to women (79.82 ±29.03 cm2 at baseline and 78.29 ±29.90 cm2 after 6 weeks). The mean of TBW in males before the start of study was 48.78 ±5.77 kg and 47.88 ±5.57 kg after 6 weeks of consumption. The results of study show the small weight loss in the both group. Therefore, the results from this study indicate that daily consumption of bitter apricot seeds produce measurable health benefits, but further studies are also required

    Background. Sea buckthorn contains almost 200 nutrients and bioactive substances, including phenolic compounds such as flavonoids, vitamins, proteins, amino acids, minerals, alkaloids, chlorophyll derivatives, amines, organic acids, fatty acids and phytosterols. Human and animal studies suggest that sea buckthorn may have a variety of beneficial effects: cardioprotective, antiatherogenic, antioxidant, anticancer, immunomodulatory, antibacterial, antiviral and antiinflammatory. Objective. The aim of this study was to evaluate the effect of regular consumption of 100% sea buckthorn juice on the risk factors of cardiovascular diseases in women of productive age with hypercholesterolemia. Material and Methods. A clinical study involved 19 women with a mean age of 54.06 ±2.97 years who consumed 50 mL of sea buckthorn juice daily for 8 weeks. Anthropometric and biochemical parameters in blood serum were monitored before the start of sea buckthorn consumption and after 8 weeks of consumption. Body composition was determined using an multifrequency analyzer InBody720. Routine biochemical analyzes were performed by standard methods in an accredited laboratory of the University Hospital by automatic biochemical analyzer BioMajesty JCA-BM6010/C. Statistical comparison between individual measurements was performed using a paired t-test, using Statistica Cz version 10 (TIBCO Software, Inc., Palo Alto, CA, USA). Results. We observed significant decrease of body weight, body mass index (P0.05). After the intervention, we observed decrease of orosomucoid, immunoglobulin A, immunoglobulin G, immunoglobulin M (P<0.001) and C-reactive protein (P<0.01). Conclusions. The obtained results support the hypothesis that the daily consumption of sea buckthorn juice for eight weeks could contribute to the beneficial effects of reducing the risk of cardiovascular diseases, such as the reduction of body and visceral fat, LDL-C, CRP and the increase of HDL-C

    Background. Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. The obesity is a global problem, which is set to increase over time. Chronic obstructive lung disease is the third-leading cause of death globally, and both obesity and diet appear to play roles in its pathophysiology (e.g., role in the development of obstructive sleep apnoea and obesity hypoventilation syndrome). However, the effects of obesity on the respiratory system are often underappreciated. Objective. The objective of this study was to compare three anthropometric methods to evaluate of fat mass in COPD patients. Material and Methods. Three anthropometric methods of evaluation fat mass in a group of 60 patients with COPD were compared. To the measurement of fat mass were used: (1) Dual Energy X-ray Absorptiometry method (DEXA), specifically by DEXA densitometer QDR Discovery Wi (S/N 80227) with additional software (Body Composition Analysis); (2) four-frequency bioelectrical impedance analysis (BIA) device Bodystat Quadscan 4000 (Bodystat Ltd, British Isles); (3) skin folds measurement (SFM) with caliper (Harpenden Lange Skinfold Caliper, Cambridge Scientific Industries, Inc. Cambridge, Maryland). The measured values were statistically processed and evaluated in a statistical program Statistica Cz. version 7.1 and Microsoft Office Excel 2010 (Los Angeles, CA, USA). Differences among anthropometric methods of measurement fat mass were tested with one-way analysis of variance (ANOVA). The data were presented as mean ± standard deviation (SD). Results. DEXA method, generally accepted for assessing body composition, showed an average value of 22.48 ±11.32 kg of fat mass, which corresponds in percentage terms to the value of 29.62±9.28. BIA method for the parameter fat mass in the monitored group of COPD patients was found the mean value 25.08±10.14 kg (in percentages 30.85±8.15). An average value 28.50±8.08% of fat mass, was determined from the skinfolds measurements (SFM) and subsequent calculations. When comparing these methods (DEXA, BIA and SFM) used to determine body composition, a statistically insignificant difference was found (P >0.05). Conclusions. In this study a good correlation between three anthropometric methods (DEXA, BIA, SFM) for measuring fat mass in patients with COPD and statistically insignificant differences between them were observed. To better define changes in the nutritional status of patients with COPD using anthropometric methods over time, further studies are needed that also monitor the consequences of clinical status, rehabilitation, and nutritional treatment

    Background. Bread is one of the world’s most consumed food commodity. However, in the last years consumption of bread and bakery products has declined, especially in the Western population. The reason for concern is the weight gain and presence of gluten in these products. Gluten is unacceptable in the diet only in patients with celiac disease who are forced adhere the gluten-free diet all the time. The consequences of gluten-free diet in healthy people are the subject of many recent studies. Objective. The aim of this study was to evaluate the changes of visceral fat area in the general population after 6 weeks of consumption of gluten-free, gluten-containing and whole-grain bread and other bakery products. Material and Methods. The study group consisted of 120 volunteers divided into four subgroups each with 30 subjects. Anthropometric measurements were made using the InBody 720 (Biospace Co. Ltd., Seoul, Republic of Korea). We used the Lookin’Body 3.0 software to process the results. The collected data from anthropometric measurements were evaluated statistically and graphically in Microsoft Office Excel 2010 (Los Angeles, CA, USA). Results. After the intervention we found out that visceral fat area values increased in probands consuming gluten-free and gluten-containing bakery products, but these changes were not significant (P>0.05; 72.7±29.18 cm2 vs 73.26±30.32 cm2 and 69.6±34.06 cm2 vs 70.34±32.33 cm2, respectively). In whole-grain and control group we observed a reduction in visceral fat area, in the control group there was a significant change (P>0.05 – 91.58±33 cm2 vs 90.47±34.37 cm2 and P<0.05 – 77.3±21.65 cm2 vs 75.56±21.87 cm2, respectively). After the intervention the visceral fat area values increased in gluten-free group in 57% of subjects, in gluten group in 73% of subjects and in the whole-grain group in 43% of volunteers. Although visceral fat area values had inceased in gluten-free and gluten-containing groups, the number of probands with reference values increased from 80% to 86% in the gluten-free group and from 43% to 66% in the gluten-containing group. In the whole-grain group we found decrease in number of subjects with reference values of visceral fat area (from 70% to 63%). There were no changes in the control group (86% vs. 86%). Conclusions. Consumption of different types of bakery products has mostly changed the visceral fat area values in a positive direction
