Conventional knowledge, resulting from observations and experience, maintains the conviction that there are gender differences in the acquisition, preparation and consumption of food. This review shows differences between the sexes in eating behavior, food choice and nutritional strategy which were conditioned by evolution and by intra-individual (biological or psychological) and extra-individual (socioeconomic and cultural) factors. Women manifest a more pronounced trust in healthy nutrition, greater engagement in controlling body weight, a higher tendency to eat in a group and in stressful situations, and they frequently experience frustration due to their own nutritional behaviors, which reflects higher social pressure and their attempts to reduce eating-related pleasure. On the other hand, men prefer fatty meals with a strong taste, and are directed mainly by the pleasure of consumption; they more frequently furtively eat sweet foods while watching television, use more dietary supplements and more frequently visit fast food restaurants. Nutritional behavior, styles of nutrition, dietary profiles, approach to nourishment, approach to the place of meal consumption, and the sources of nutritional knowledge all demonstrate associations with gender. Reciprocal interactions between gender and diet are conditioned by physiological, psychological and sociocultural factors. This system of reciprocal interactions includes feedback: biological sex and cultural gender shape one's diet and, reciprocally, one's diet affects the deepening or flattening of gender differences. The analysis of reciprocally interacting factors entangled in the formation of a nutritional model may also represent an important element of pro-health prophylaxis and should be used in medical and dietary practice. Males in particular should be informed and educated about health-promoting diets.
Background: Recent studies indicate the important role of chronic inflammation and oxidative stress in the pathogenesis of hypertension. Green tea, due to the high content of catechins, shows high antioxidant activity. Objective: To determine the effect of supplementation with green tea extract on the blood pressure, on the concentration of selected parameters of inflammation and antioxidant status in the model of high-sodium-diet induced hypertension. Design: The study lasted 42 days. The experimental population consisted of 30 rats. The rats were divided into three groups. The rats in the control group were fed a standard diet with 35 g of NaCl per kg of diet, in the second group hypertensive rats were fed a standard diet with NaCl (35 g/kg diet) and with an extract of green tea (2 g/kg diet). The third group consisted of hypertensive rats fed a standard diet with NaCl (35 g/kg diet), and 4 g of green tea extract/kg diet. Results: Supplementation with green tea had no effect on body mass of rats on a high-sodium diet. At the end of the experiment systolic blood pressures in SH2 and SH4 groups were significantly lower than in the control group SK. The SH4 group was characterized by a significantly lower diastolic blood pressure value and concentration of TNF-α in comparison to the SK group. The rats from both SH2 and SH4 groups were characterized by higher total antioxidant status values compared to the control group. Discussion: The mechanism of the beneficial effects of green tea on blood pressure is not clear, but it is believed that it is related to its omnidirectional properties. Conclusions: Supplementation of green tea has a beneficial effect on blood pressure, markers of inflammation and antioxidant status in an experimental model of hypertension.
IntroductionOur aim was to evaluate the effects of metformin and orlistat on body composition and glucose–insulin homeostasis in obese premenopausal women.Material and methodsSeventy-three obese premenopausal Caucasian women aged 32.4 ±8.3 years were treated with either metformin (1000 mg/day; n = 37) or orlistat (360 mg/day; n = 36). Anthropometric parameters were measured using dual-energy X-ray absorptiometry. Glucose tolerance, using the oral glucose tolerance test; insulin resistance, using the homeostasis model assessment (HOMA-IR); and insulin sensitivity, using the Matsuda insulin sensitivity index (ISI Matsuda), were assessed at the commencement of the study and after 3 months.ResultsThose treated with orlistat showed greater weight loss (−9.4 ±2.3 vs. –4.9 ±1.3 kg, p < 0.05) and decrease of fat mass (−5.4 ±3.0 vs. –3.5 ±0.7 kg, p < 0.05) than those treated with metformin. The percentage of android and gynoid fat deposits was reduced in both groups; however, a greater decrease in android fat was observed in those treated with metformin. Improvement in ISI Matsuda and post-load insulin were similar in both groups. High initial post-load insulin and low ISI Matsuda corresponded with reductions in total fat, trunk fat, and waist circumference in both groups, and a decrease in android fat in those treated with metformin.ConclusionsOrlistat treatment resulted in greater weight loss and improvement in body composition; metformin treatment resulted in a reduction of android fat. Both drugs produced a comparable improvement in insulin/glucose homeostasis. Overall, insulin-resistant women showed improvement with treatment, irrespective of which drug was used.
Patients with lysosomal storage diseases (LSDs) suffer from physical and mental disabilities, which together with poor access to professional care may lead to impaired oral health. This cross-sectional case-control study characterized the status of oral health in patients with LSDs in Poland. Thirty-six children and young adults with various forms of LSDs were examined. The data were compared with those from age- and sex-matched healthy controls. Exemplary cases were presented to highlight typical problems in oral care associated with LSDs. When possible, saliva was collected and analyzed for total protein, inflammatory mediators, and antioxidant status. Generally, patients with LSDs had significantly higher prevalence of caries, inferior gingival status, and inadequate oral hygiene. The severity of oral health impairment in mucopolysaccaridoses, the most common LSD in Poland, was similar to that seen in patients with mannosidoses or Pompe disease. Saliva could be collected only from few less handicapped patients. In MPS, it did not appear to differ significantly from the controls, but in patients with Pompe disease it contained lower concentrations of vascular endothelial growth factor (VEGF) and monocyte chemoattractant protein-1 (MCP-1), but higher levels of tumor necrosis factor receptors 1 and 2 (TNF-R1, TNF-R2) and myeloperoxidase (MPO). In conclusion, Polish patients with LSDs have an inadequate level of oral hygiene and substantially deteriorated oral health.
