Oxidative stress is considered as a likely causative factor in the development of insulin resistance leading to diabetes mellitus. Meals rich in lipids disturb the redox balance in humans. Some nutrients such as n-3 long-chain polyunsaturated fatty acids may enhance the oxidative processes, however many studies underline their possible beneficial effect in the prevention and treatment of diabetes...
Two therapeutic diets have been formulated (A & B) and prepared in bakery form for patients with liver cirrhosis. The formulation was based on the presence of protein of high Fisher ratio and fat rich in medium chain triglycerides. Both formulas contained edible sources of antioxidants. Honey was added as a sweetener. Proximate analysis of Formula B and its contents of amino acids and fatty acids...
The aim of this work was to estimate the influence of pH24 and intramuscular fat content on culinary quality of meat. The research was executed on 60 hogs. The percent of meat in carcass after slaughter was estimated and the samples of Longissimus lumborum muscle for the next studies were taken. The fat and protein content, pH after 1, 3 and 24 h post mortem, natural drip loss, parameters of meat...
We analysed the body composition of mother-daughter family pairs in relation to calcium and dairy products intake. The study covered 277 mother- daughter family pairs, aged 43.7±5.5 and 17.1±2.3 years, respectively. Dairy products (g/person/day) and usual calcium intake from dairy products and from daily diets (DD) were assessed with the food intake frequency method, using the validated ADOS-Ca questionnaire...
The aim of this study has been to determine the influence of high temperature (150°C) and layer thickness of lard used upon changes in the content of cholesterol and formation of cholesterol oxidation products (COPs). It was found that heat treatment in a thin layer of lard was characterised by a more intensive degradation and thermal oxidation of sterols in comparison to heating a thick layer of...
The hydrolysis of egg-white protein precipitate (EWPP) with trypsin, chymotrypsin, and elastase was studied. The peptides obtained were determined for their antioxidative properties. Chymotrypsin caused the most extensive degradation of EWPP. The degrees of hydrolysis (DHs) of the one‑hour hydrolysates were 77.6%, 55.8%, and 43.3% for chymotrypsin, trypsin, and elastase, respectively. Only small peptides...
Lifestyle modification, including dietary changes, is very important in the prevention and treatment of hypertension. It has been well documented that DASH (Dietary Approaches to Stop Hypertension) diet has the potential to lower blood pressure and to improve patients’ overall health. The aim of this study was to evaluate compliance to DASH diet by patients with essential hypertension. A total of...
The aim of the research was to determine the antioxidant properties of tea and herbal infusions and the content of total polyphenols. The research material were teas and herbal teas available in retail trade, i.e.: Camellia sinensis teas such as green, black, Pu-erh and white tea as well as herbal teas from lemon balm leaves (Folium Melissae), peppermint leaves (Folium Menthae Piperitae) and chamomile...
The aim of this work was to analyse a relationship between microstructure parameters of Longissimus muscle after heat treatment and technological and sensory quality of pork meat. The research was executed on a group of 40 hogs originating from crossing Naïma sows with hybrids P76-PenArLan boars. The animals were slaughtered at 105 kg live weight. Following the slaughter, the percent of meat in carcass...
The study was undertaken to investigate the effect of RS4 resistant starch in high-fat diets on the apparent absorption of magnesium (Mg) and iron (Fe) in Wistar rats. The animals (4 groups of males, n=32) were fed 4 types of diets: a control diet with 15% addition of soybean oil (K1) and a control diet with 15% addition of lard and cholesterol (K2) as well as 2 respective experimental groups with...
The folic acid intake is definitely lower than the recommended dietary allowance. This study shows the possibility of enhancing the synthesis of folates by the baker’s yeast. p-Aminobenzoic acid (PABA) addition to the examined culture media at doses of 5–25 μg/cm3 increases the content of folates, which in turn depends on the strain and PABA dose. The culturing of yeast with PABA might form the basis...
The objective of the reported study was to determine the effect of meat sonication within up to 2 h after slaughter with low-frequency ultrasounds (25 kHz) and at medium vibration intensity (2 W/cm2) on selected properties of myofibrilar proteins of the I-Z-I band isolated from ageing beef. Proteins were isolated directly after sonication as well as after 24, 48 and 72 h of storage at a temperature...
Mulberry trees are distributed throughout Pakistan. Besides its use in forage and food for animals, it is also used as herbal medicine. This study is carried out to determine phenolic acids profile, sugar content, and the antioxidant activity of the leaves and fruits of three mulberry species (Morus alba L., Morus nigra L. and Morus laevigata W.) grown in Pakistan. Dried fruits and leaves of three...
Classification of proteins as precursors of bioactive peptides is presented in this work. To achieve this aim, the worldwide available computer databases such as BIOPEP, CATH, PDB, and SCOP were applied. The main qualitative criterion to classify the proteins was the integrated coefficient of biological activity of protein (C) defined as a square root of the sum of squares of (A) for different activities...
Type 2 diabetes mellitus is a world wide problem, with obesity being a primary risk factor of this disease, mainly caused by poor diet and lack of physical activity. In the diet of subjects with diabetes, it is not only the quantity but also the quality of fat ingested that appears to be of great importance. Presented in this article is a review of the role of nutritional fat on insulin signaling...
Benzene is an aromatic hydrocarbon. It gives rise to the production of oxygen radicals or reactive oxygen species (ROS), which are the means of the metabolic activation of benzene and are the source of its toxicity. This study was conducted to assess the ability of some food stuffs such as carrot and wheat germ oil to protect against benzene toxicity. Experiments were carried out on albino rats injected...
The aim of the study was to obtain soluble and extruded starch preparations from potato starch, then to subject them to roasting with phosphates and/or glycin as well as to assess the effect of the order of double chemical modifications on their properties. The soluble starch was prepared by Lintner method, whereas the extruded starch was obtained using a single-screw extruder at 140-160-180°C. The...
The production of probiotic cheeses is increasing. Probiotics cheeses always need the application of both traditional mesophilic starter cultures and probiotic strains of lactic acid bacteria (LAB). The manufacture of probiotic cheese only with probiotics is not possible because of their weak growth in milk and the lack of proteolytic activity. The aim of this work was to determine the dynamics of...
Analyses were conducted for calcium intake from dairy products linked with the consumption of calcium supplements and consumption of calcium- fortified food in respect to bone mineral density (BMD) of women (n=39) aged 34-56 years. A relationship was demonstrated between bone mineral density (BMD) of the women and calcium intake from dairy products, calcium-fortified food products and calcium supplements...
The objective of this research was to evaluate the impact of different protective atmospheres, with or without the addition of lysozyme, which were used to pack swine longissimus muscles kept in cold store conditions for the period of up to 3 weeks. The employed atmospheres comprised: vacuum, modified atmosphere with carbon oxide (70% CO2, 29.5% N2, 0.5% CO) MAP-CO and with oxygen (79% N2, 20% CO2,...
