The paper focused on the evaluation of a fatty acid profile and mineral component contents in milk obtained from cows of 5 breeds maintained in Poland. The studies covered 147 milk samples collected from cows of Polish Holstein-Friesian black-white (42) and red-white (26) varieties, Simental (31), Whitebacks (15) and Polish Red (33). Milk was sampled at the spring-summer season when dietary units...
This work was addressed to monitor some quality indicators content in commercial powdered infant milk formulas. Furosine, furfural compounds, vitamins (B1, B2, B6, and C) were determined in starting and follow-up infant milk formulas. Contents of furosine, total and free furfural compounds, and B group vitamins were assayed by RP-HPLC with UV detection. The contents of furfural (F), free and total...
The study included 9339 people aged from 13 to 75 years, inhabiting 6 macro regions of Poland. Thirty choice factors of dairy products were evaluated. A statistical analysis of the results obtained was carried out after separating the following factors: sensory, functional, health, economic and socio-cultural ones. Dairy product’s choice was more affected by sensory and functional factors than the...
The aim of the study was to prepare a tool for quantitive evaluation of calcium intake and its calibration. The ADOS-Ca test calibration was carried out by the 24-hour recall method repeated seven times. The study included 90 people (aged 22.6±0.1) who gave complete information, i.e. 630 nutrition interviews and 90 ADOS-Ca tests. Calcium intake from dairy products estimated by the test was stated...
It is well documented that hospital malnutrition and inadequate food intake are very common, and many patients lose weight during admission. Rapid weight loss may have adverse effects on the outcome of illness and increase mortality and total costs of treatment. In 1999 the Council of Europe established a Commission of Experts to collect information regarding nutrition programmes in hospitals. The...
High dietary glycemic index (GI) may increase colorectal cancer risk by affecting insulin and insulin-like growth factor-I levels. Colon polyps are a pre-malignant condition. We examined carbohydrate intake, the value of GI and glycemic load (GL) in patients with colon polyps recognized as adenomas (n = 83) in comparison with patients with normal result of colonoscopy (n = 73). The mean intake of...
The aim of our study was to estimate the intakes of energy and macronutrients by patients with hypertension and normal (NGT) or impaired glucose tolerance (IGT). Thirty six patients with medically treated essential hypertension, 18 with NGT and 18 with IGT, were included in the study. Over 80% of individuals with NGT and 70% with IGT were overweight or obese, and approximately 60% of them had waist...
The aim of the study was to estimate the effect of 5% and/or 10 % of inulin and/or oligofructose on thiamine level in blood serum and urine. The vitamin was administered in doses of: 20 or 40 μg/day/rat. With respect to the control (fructan-free), the diet containing 5% of inulin decreased (p<0.05) serum thiamine level when the lower daily vitamin dose was used, and oligofructose had no influence...
Recent studies suggest a key role for tissue aberrant expression of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) and for tissue glucocorticoid excess in dysregulation of metabolism observed in diabetes and other metabolic disorders linked to central obesity. In an experiment carried out in 50 adult Wistar rats fed on diets containing sunflower oil, rapeseed oil, lard or cod liver oil at two...
The aim of the study was to determine whether consumption of diets containing different fat (rapeseed oil or lard-rich), supplemented with a high level of cholesterol (3% w/w) and/or vitamin E (500 mg/kg of diet) for 6 weeks influenced 17beta-hydroxysteroid dehydrogenase (17β-HSD) type 3 activity (measured in vitro), testosterone (Tt) content in testes and plasma testosterone (Tp) concentration (measured...
This study examines eating habits and weight in a representative national sample of Poles. We found bad eating habits (e.g. eating mindlessly when not hungry or when encouraged by others) predict BMI and the desire to loose weight quite well. Other predictors depend on gender and control over preparing meals. Men who have a good education, watch more television, eat meals prepared by others, are heavier...
The influence of calcium intake on bone mineralisation was evaluated in 200 girls at the age of 11-15 years and 97 women at the age of 20-23 years from a random sample of general population. The nutritional value of diets was estimated with the use of a three-day record method. Bone mineral density (BMD) of two points of radius was measured by a p-DEXA device. Mean daily intake of calcium accounted...
This study analyses the nutritional value of diets consumed by boys with two different food patterns, expressed as a different frequency of consuming pork and poultry or snacks, sweets and sweet drinks. Two hundred and fifty-three boys aged 15-18 years from secondary schools of various types situated in the Suwałki region and in the city of Olsztyn were included in the study. The factor analysis was...
The paper reviews the human intestinal microflora and the effects of probiotics on human microecology. The aspects of probiotic strain selection as well as implications of such selection for health and improved quality of life were taken into consideration.
The aim of this study was to asses the effect of glutamine-supplemented total parenteral feeding on clinical and nutritional states in severe inflammatory bowel diseases (IBD). Twenty seven patients with severe IBD were qualified to total parenteral feeding with or without glutamine. The clinical, metabolic and nutritional improvements have been analyzed after 14-day treatment. Though, we were able...
Emotions have been observed to distinctly influence food choice in conditions when a vast number of women (82%) have no suffered from hunger before eating. This means that food intake is influenced by emotional hunger rather than the physiological one. The mostly preferred food at negative moods, like anger, sorrow, fear or stress, have been sweets. Boredom has favored eating of an increased amount...
There are sparse data on supplementation practice related to folic acid (FAS). The prevalence of FAS usage in different European countries/areas varied from 10% to 43% among women before pregnancy, from 9% to 80% during pregnancy and from 0% to 53% in other population groups. With respect to public health, the results of this study indicate that there is a need to consider which strategy of increasing...
The main objective of this study was to investigate attitudes towards sugar-free products in a group of 74 diabetics from Warsaw region. The diabetics were asked questions about use of specific diets, intake of sweeteners and habits concerning consumption of all food products containing artificial sweeteners. On average, the majority of diabetics avoided sweetening meals/beverages with sucrose, although...
Nutritional patterns of 400 children (212 girls and 188 boys) selected at random from the whole territory of Poland, aged 4, have been assessed. The study was realised in Spring 2005 by way of a 7-day consumption record participated by mothers and kindergarten caretakers. The share of children using dietary supplementation, taking into account all analysed components, was 26.2 (22.2% girls and 30...
The aim of the study was to describe the role of psychosocial determinants of using vitamin and mineral supplements among students. Through using the theory of planned behaviour, a more detailed approach to assess the psychosocial factors influencing dietary supplement use among students was created. Attitude toward behaviour was the statistically significant factor influencing both intention and...
