Filter by:The purpose of this prospective cohort study is to investigate breast-milk and breastfeeding among infants who are exclusively and partially breastfed at 6 months of age in terms of characteristics that are hypothesised to contribute to growth and development of body composition in infancy. The scientific originality lies in the simultaneous sampling of multiple factors that are believed to contribute to growth and development of body composition in infancy, i.e. energy content of breast-milk, metabolism-regulating hormones in breast-milk, infant temperament and appetite. The selection of two predefined study groups, i.e. infants exclusively breastfed until 6 months of age and infants given complementary foods in addition to breast-milk from 3-4 months of age, gives the opportunity to describe, and perhaps up to some point compare, what now is described by the World Health Organization and in official Icelandic infant recommendations as "optimal feeding" and what studies have suggested is "common feeding" in many countries. The methods are carefully chosen, i.e. appropriate and non-invasive isotopes and validated questionnaires are used. To our knowledge, no study has reported breast-milk composition in exclusively vs. partially breastfed infants.
Sugars have been implicated in the epidemics of overweight and obesity. This view is supported by lower quality evidence from ecological observations, animal models, and select human trials. Higher level evidence from controlled trials and prospective cohort studies has been inconclusive. Whether sugars contribute to weight gain or increases in adiposity independent of their calories and whether important food sources of sugars other than SSBs are associated with a higher risk of overweight and obesity or weight gain remain unclear. To address the uncertainties, the investigators propose to conduct a series of systematic reviews and meta-analyses of the totality of the evidence from controlled trials and prospective cohort studies to distinguish the contribution of fructose-containing sugars and important food sources of sugars (SSBs, fruit, 100% fruit juice, cakes/sweets, yogurt, cereals, etc) from that of energy in the development of overweight and obesity. The findings generated by this proposed knowledge synthesis will help improve the health of consumers through informing evidence-based guidelines and improving health outcomes by educating healthcare providers and patients, stimulating industry innovation, and guiding future research design
Nowadays increasingly quest for improved physical appearance, gradually developing the medicine of beauty, where the radio fits as an additional tool in helping some aging processes and maintenance of body shape. The aim of this study was to evaluate and compare the changes in the thickness of adipose tissue and blood levels of some biochemical markers of sedentary and active women who underwent radio frequency technique via ultrasound imaging and laboratory tests. Seven (7) sessions were held, each lasting 20 minutes each, 22 volunteers allocated into two groups, sedentary and physically active. Measures ultrasound image were collected at baseline, pre-treatment and post-treatment period period and serum biochemical parameters (lipid profile, liver and kidney) for the pre-treatment and post-treatment.
Obesity is considered to be caused by an imbalance between energy expenditure and energy intake. A major determinant of our daily energy intake is the size of the meals that we consume. It has been suggested that decisions about portion sizes are often made in advance, before a meal begins. This pre-meal planning is considered to especially depend on the estimated 'expected satiety' and 'expected satiation' of different foods. Further, also factors like weight concern and palatability of the food might have their influence on meal size selection. In general, it is not clear how these factors are integrated during pre-meal planning and which brain networks are involved in these decisions/this process. Thus, the investigators plan to study pre-meal planning in healthy, normal-weight and overweight/obese individuals with functional magnetic resonance imaging under different cognitive instructions including pleasure, expected satiety and self-control in terms of health consequences. The investigators will explore the neural networks involved in pre-meal planning and expect them to be modulated by the before mentioned factors. Further, the investigators plan to explore gender differences and expect that female subjects will select smaller portion sizes especially in the self-control condition as they are often more concerned about their weight/health. Finally, the investigators will explore differences between lean and overweight subjects to elucidate factors that might lead to increased meal sizes in overweight subjects.
BACKGROUND: The Southern European Atlantic Diet (SEAD) is the traditional diet of Northern Portugal and Galicia, a region in northwest Spain. The SEAD has been associated with a lower risk of non-fatal acute myocardial infarction. Possible mechanisms of this association may be related with a lower concentration of markers of inflammation and with reduced triglycerides, insulin, insulin resistance, and systolic blood pressure. Aim: To evaluate the effect of an Atlantic Diet on i) lipid profile, ii) markers of inflammation, and iii) anthropometric indices in a population-based study METHODS: This is a non-pharmacological clinical trial study which is performed on a family-oriented basis. 250 families (~ 750 children and adults, older than 3 years) were selected to participate in the study and randomized into Atlantic Diet (AD) (n=125 families) and control (n=125 families) groups. The AD groups participate in a diet program 1 day a month for 3 months in 120-minute diet sessions and freely receive AD food, characterized by a high intake of vegetables, cheese, olive oil, mussels and by wine consumption during meals. Control group subjects do not participate in any regular diet activity during this period and did not receive additional food. Exclusion criteria are alcoholism, lipid treatment, dementia, and terminal disease. Weight, BMI, waist circumference (WC), skin folds, nutrient intake from 3-day recalls, food frequency questionnaire, physical activity, blood pressure, metabolic function (fasting blood glucose, HBA1c, insulin resistance and lipid profile), and inflammation markers (c-reactive protein, interleukin 6 and tumor necrosis factor-alpha) are measured at baseline, 3 and 6 months. Mixed effect models will be performed to assess the significance of changes in the cardiometabolic parameters. The primary end point is the change in lipid profile compared with baseline and the control group arm at the end of Month 6. The secondary exploratory end points were change in anthropometric indices and inflammation markers at Month 6.
The purpose of this study is to investigate the effects of a synbiotic (ProSynbiotic) on the gut microbiota composition, body composition and adiposity-related genes and metabolic markers in healthy overweight adult subjects.
This project examines behavioral and household characteristics associated with food purchasing patterns.
Food aromas are a part of foods' flavor, and can promote overeating. Alcohol consumption also stimulates appetite, and contributes to overeating while under alcohol's acute effects. Knowing the brain regions that respond to food aromas and alcohol, and how they are modified by the amount of body fat and alcohol exposure, will provide critical information about the neural systems that underlie loss of control of eating. Therefore, the main hypotheses of this study are that: A) Lean and obese subjects have different brain responses to food aromas that enhance desire to eat, and B) Acute alcohol intoxication i) enhances the brain's response to food odors, and ii) affects brain systems that inhibit or terminate eating. To test these hypotheses, we have modified functional magnetic resonance imaging (fMRI) paradigms successfully used to study alcoholic drink aromas in subjects at risk for alcoholism.
Coordinated project whose objectives are: a) to assess the effectiveness of a physical activity intervention (MOVI-KIDS) on preventing obesity and improving fitness during the adiposity rebound period; and b) to examine the effectiveness of MOVI-KIDS on reducing the carotid intima-media thickness.
A randomized double-blind placebo controlled intervention study with pregnant obese women (n=440) will be conducted. The intervention will involve consumption of fish oil and/or probiotic capsules from early pregnancy until 6 months after delivery. The aim of the study is firstly to investigate the effects of the supplements on the risk of gestational diabetes mellitus and obesity in the women and secondly to modify the risk markers of allergy and obesity in children of the women. Also the underlying metabolic mechanisms will be investigated. Follow up visits at child's age of 5 to 6 years will be conducted to evalute long-term effects on maternal and child health. The aim is to investigate the impact of dietary intervention, diet, maternal overweight/obesity and gestational diabetes status as well as gut microbiota and metabolism during pregnancy on maternal and child's health, allergy and child neuropsychological development.
