Prebiotics and probiotics are thought to play a role in appetite control and body weight regulation; but little is known about this topic. This study was planned to examine the effects of inulin and Lactobacillus casei 431 on short and long term fasting, satiety, dietary intake, and serum hunger and satiety hormone levels. The study consisted of 2 phases. In the first phase, a double-blind, randomized, crossover study design was used, and it was performed with 16 healthy male participants aged 19-30 years. In this phase, the prebiotic (200mL milk+16g inulin), probiotic (200mL milk + Lactobacillus casei 431 [>106 cfu/mL]+16g maltodextrin), synbiotic (200mL milk+16g inulin + Lactobacillus casei 431 [>106 cfu/mL]) and control (200mL milk+16g maltodextrin) test drinks were consumed with a standard breakfast on four separate test days by one week intervals, and their effects on dietary intake, hunger, satiety and appetite were assessed. The second phase was performed with 21 healthy male participants aged 19-30 years, using a placebo-controlled double-blind, randomized study design. Participants consumed the control (200mL milk+16g maltodextrin) or synbiotic (200mL milk+16g inulin+ Lactobacillus casei [>106 cfu/mL]) test drinks for 21 days with their habitual diet. At the beginning and end of the intervention, blood samples were collected at 0., 30., 60. and 120. minutes following the test day protocol to analyse serum glucose, insulin, ghrelin, obestatin and PYY (peptide tyrosine tyrosine) levels. In addition, dietary intake, hunger, satiety and appetite of participants were compared.
Despite the intensive worldwide research dedicated to the nutrition and faecal microbiota, the studies that follow the link between the early nutrition, initial intestinal microbiota, and development of children over a longer time period are limited. From 2010 to 2013, the investigators conducted a study "My-Milk" in Slovenia. From 185 participating pregnant women involved in the detailed part of the protocol (comprising of 4-days weighed dietary record, visits at clinic and biological sample collection), 152 participants completed the study at the child's first year of age. Five of the participants bore twins whose data was excluded from the research because infant's identity was not consistently followed throughout the research. In addition to studying the microbiota and fatty acid composition of breast milk and the initial development of intestinal microbiota of breastfed babies, the investigators also monitored the diet of expecting and nursing participants, concentration of vitamin D in serum and bone mineral density in participating mothers and children. The investigators performed anthropometric measurements of children during the first year of age. All singleton children who have completed My-Milk study (N= 147) will be invited in the follow-up study "My-Milk-2". The first step of the proposed study will be the evaluation of nutritional status of children aged 6 to 7 years in 2017/2018, including the assessment of the body composition (bone density, percentage of fat and muscle tissue), health indicators (blood pressure, blood cholesterol, frequency and severity of infections) and fecal microbiota. The obtained data of My-Milk and My-Milk-2 studies will enable the prospective cohort study to be carried out on the effects of early nutrition and various factors of mother and child during the first year of age on the health and developmental status of children aged 6- 7 years. The project results will significantly improve the progress in research areas of public health and nutrition. The interactions along the axis nutrition in early childhood, gut microbiota composition/ diversity and potential health problems in later life are still not fully explored. The investigators expect the results of the proposed study will contribute to the scientific development in this field in global prospective. The acquired information will also be an excellent basis for development of new dietary guidelines for children.
This project will pilot test a new app for self-monitoring food intake using natural spoken language (by voice recognition or text) to provide daily estimates of energy and nutrient intakes with a phone app.
Patients with NAFLD and matched controls will be asked about their demographic status, and their previous year dietary intakes using a validated FFQ.
