Study aim: To determine the effects of indoor cycling training combined with restricted diet, lasting 12 weeks, on serum lipid concentrations in obese women.Material and methods: Twenty women aged 23.8 ± 3.6 years were randomly assigned into two groups: control (C) and experimental (E), the latter subjected to indoor cycling at various loads, 3 sessions weekly, every session lasting 45 min, combined with restricted diet (about 1200 kcal daily) for 12 weeks. The following variables were recorded: body height and mass, BMI, relative body fat content (from 7 skinfolds), fat-free mass, triglycerides, cholesterol and lipoproteins (HDL, LDL, VLDL).Results: Significant increase in HDL and significant decreases in all other variables (except body height) were noted only in the experimental group.Conclusions: Indoor cycling associated with restricted diet is an excellent option in controlling obesity and serum lipids.

Food-drug interactions can have a significant impact on the efficacy of pharmacological treatment and the adverse effect profiles of many treatments. Interactions are not necessarily harmful to therapy, but they can be employed to promote drug absorption or reduce side effects in some circumstances. Drug interactions with grapefruit juice, in particular, have gotten a lot of attention recently. As new drugs are approved at a faster rate, there is less information accessible concerning their side effects and interactions once they hit the market. The use of herbal medicines and dietary supplements is a second source of worry. These items are not subjected to rigorous testing and may contain little or no of the ingredient listed on the label. Some of the herbs utilized have the potential to interact negatively with prescription medications. Mahuang (ephedra) and fever few are two noteworthy examples. Mahuang is a stimulant that can lead to hypertension in those who are on monoamine oxidase inhibitors. Fever fever has anticoagulant qualities that can help warfarin work better. The majority of food-drug interactions occur due to one of three mechanisms: decreased absorption rate or extent, enhanced absorption rate or extent, or chemical/pharmacologic effects. Acid-labile medicines, such as penicillin G, ampicillin, and dicloxacillin, are destroyed when there is an increase in stomach acid. In other circumstances, dietary components like calcium or iron may create compounds with the medicine that make it harder to absorb. Tetracycline, sodium fluoride, and ciprofloxacin are some examples. Food, calcium, and practically everything, including orange juice and coffee, interfere with lendronate absorption. The exact process through which food interferes with absorption is unknown in many circumstances. The area under the curve (AUC) may be comparable regardless of how the drug is administered; delayed absorption does not always diminish total overall exposure to the drug.

The presence of selenium (Se) in foods and the pertinent toxicological data are reviewed. In most regions of the world, the average daily intake of man is thought to be between 60 and 250 micrograms for adults and between 4 and 35 micrograms for infants. The current practice of adding selenium supplements to animal feeds may increase the selenium content of meats by up to 30%, but this does not result in a biologically meaningful increase in the selenium intake of people. Se is mostly absorbed after ingestion, according to the available metabolic data. Up to 50% of it is eliminated in the urine, while the remaining percentage builds up primarily in the liver and kidneys. Recent epidemiological and animal studies show that Se is not a carcinogen, and in some cases may have anti-cancer properties. Neither the essentiality for man, nor the no-effect level of Se have been established.

B cell activation factor (BAFF) is a recently discovered member of the TNF ligand superfamily secreted by adipocytes, previously linked to autoimmune and lymphoproliferative disease. The aim of this study was to investigate the relationship between BAFF plasma levels and the non-modified, usual dietary composition as well as obesity-related anthropometric parameters in a cohort of 58 obese and non-obese Central-European Caucasian individuals. We found that BAFF had an independent predictive role for percentage of body fat; moreover, BAFF levels were correlated with waist and hip circumference. BAFF plasma levels were also significantly correlated with investigated dietary composition based on the 7-day food records, as the BAFF levels correlated with the percentage of energy derived from the carbohydrates and with energy derived from the dietary fat. Our results suggest that BAFF may play a role in linking the immune status and metabolic response to diet.

It was reported that dietary fructose imposes a number of effects on lipid metabolism including hypertriglyceridemia. The daily intake of fructose in humans is mainly due to sucrose. It was reported that the consumption is still increasing, making a background for health implications. The mechanism of metabolic disorders is poorly understood, but a lot of studies indicate that the liver lipid homeostasis deregulation is essential for a fructose effect on metabolism. The aim of the study is to estimate if fructose affects the profile of fatty acids in in vitro and in vivo models. In this study in vitro and in vivo experiments were conducted to assess the effect of dietary fructose on the fatty acid profile in the cell culture or in the liver of rats. The results showed that in the fructose experimental groups, both in the cell and liver homogenates, the content of the saturated fatty acids were significantly higher than in control groups. According to the obtained data fructose in the medium and in the diet affects saturation of fatty acids in the cell cultures and in the livers of rats. The findings obtained in the experiments support the thesis that fructose influences the homeostasis of lipid metabolism in the liver and may give an opportunity to discuss the limitation of the content of this kind of sugar in food.
