Filter by:The goal of this this intervention is to test the degree to which a portion size labeling intervention influences consumer selection of smaller portions at two large cafés. The main question it aims to answer is: Do consumers order fewer calories when the portion size label for the smaller entree is called "standard" instead of "small"? Participants will order lunch as usual in the two cafes (one intervention, one control) for 5.5 months, and all order items will be recorded in the check-out system. One cafe will receive the labeling intervention, while the other will not. Researchers will compare the average calories per order between the two cafes to see if there are differences.
Obesity is currently one of the most substantial health burdens. Due to the production of marked and sustained weight loss, bariatric surgery is an increasingly used therapeutic modality to combat obesity and its comorbidities. Surgical rearrangement of the gastrointestinal tract remarkably alters metabolism and hormones acting on neurological and hypothalamic signalling, involved in food decision-making and eating behaviour. In this context, many patients who underwent bariatric surgery self-report changes in appetite, satiety and food preferences. Furthermore, new gut hormone-based (e.g. GLP-1 receptor agonist or GLP-1-RA) pharmacotherapies which mimic the effect of bariatric surgery show impressive efficacy on weight reduction by modulation of food behaviour. However, the mechanisms of such functional changes, and how they relate to food decision-making and food purchase behaviour remain unknown. In Part 2 of the BrainFood-project, the investigators propose a novel approach using digital receipts from loyalty card to unravel the effect of obesity treatments (surgical and non-surgical) on eating and food purchase behaviour in daily life.
In recent years, social pressure has been exerted towards lowering sugar and sweetness levels in foods, with the aim of decreasing the sweetness preference of the general population. However, the resilience/flexibility of sweetness preferences and the impact on energy intake is a fundamental knowledge gap. Recent, relatively long-term studies limited to no more than 3 months did not find a relationship between sweetness exposure and sweetness preferences. Therefore, a longer-term systematic investigation is necessary to objectively evaluate whether sweetness preferences can be altered via varying the sweetness exposure and whether it can affect other outcomes, such as perceived taste intensity, food intake, body weight, body composition, glucose homeostasis and sweet liker type. The study sample will consist of 180 subjects. Enrolled participants will be distributed into three intervention groups; regular dietary sweetness exposure (n=60); low dietary sweetness exposure (n=60); and high dietary sweetness exposure (n =60). The intervention is semi-controlled for a period of six months. Preference and perceived taste intensity of a series of familiar and unfamiliar foods will be assessed at baseline (Day 0), during the intervention (Month 1, Month 3, Month 6) and in the follow-up period (Month 7, Month 10). Furthermore, outcomes such as observed food choice and intake during a test meal, reported food preferences, reported food cravings, sweet-liker type, glucose homeostasis, body weight, body composition and biomarkers related to diabetes and cardiovascular disease will be assessed as well.
Unhealthy eating habits are a social challenge in this century, regarding that children usually refuse to eat and taste fruits and vegetables. The Dastatuz project aims to study children food neophobia (the term used referring the reluctance to taste new foods) and fruit and vegetables acceptance. It pretends to tackle the issue from an early stage: pregnancy, lactation and complementary feeding. In this sense, the Project aspires to assess the possible impact of maternal diet and complementary feeding on young children eating behaviour until 18 months of age. In addition, it intends to study the effect that the type of complementary feeding (spoon-fed or baby-led) might have on that eating behaviour. Considering these objectives, a quasi-experimental, multicenter, controlled and prospective intervention study is proposed. If it proved to be effective, this experience would have a high potential to be transferred and would open the possibility to give way to future public programs or guidelines, as a basic and easy solution to achieve higher fruit and vegetable intake among children and, consequently, the potential health benefits this may bring. Besides, taking into consideration the above mentioned ideas, the investigators hypothesized that a high intake and variety of fruit and vegetables (FV) during pregnancy and breastfeeding will lead to distinctive sensorial experiences for the baby, different from those of the babies whose mothers following a "standard diet" (as described in the National Nutrition Surveys). This consumption profile will promote the acceptance of fruits and vegetables along complementary feeding. Additionally, a correct baby-led weaning (BLW) may also contribute to establish these healthy eating habits.
