The primary aim of this study is to reduce household food waste and improve individual nutrition. This will be achieved using the FoodImageTM smartphone app 1, a novel method for measuring household food acquisition, food intake, and food waste decisions, to assess the efficacy of a smart intervention that targets food waste reduction and diet quality improvement. The intervention is designed to improve nutrition by offsetting intake of less nutritious foods with increased fresh fruit and vegetable (FV) intake while simultaneously reducing household food waste via strategies tailored to participating households.
In a double-blind, repeated single-arm trial, 8 healthy adults consumed 20 grams of formula that contain 60.2% inulin (w/w) dissolved in 100 ml of water. Blood glucose was measured in fasted participants and at, 30, 60, 90, and 120 minutes after starting to eat a prepared meal (470 Kcal). As supplementation controls, the investigators used the vehicle-glucose, dextrose, isomaltooligosaccharides (IMO), or the combination of IMO and Inulin solution 20% (w/v).
With this study, researchers want to conduct ambulatory studies in which people (healthy, with T2D, or at-risk of T2D) will consume a variety of pre-set and conventional meals in free-living conditions while wearing one or more continuous glucose monitors (CGMs) and, to assess physical activity, a smart watch. With data from these devices, researchers will develop algorithms that can predict the content of a meal.
The study plans to start in July 2021, and it is expected that 20 healthy people (aged 18-70 years old, BMI 18.5-40kg/m2) will carry out a 5-week intervention and follow-up. Participants will be enrolled in the group through the screening and plan to take regular diet, OGTT, high-fat diet, low-calorie diet and ketogenic diet within 5 weeks. The proteomics and metabolomics indicators of tear, plasma, and urine specimens will be measured at 5 time points at baseline, 30 minutes, 1 hour, 2 hours, and 3 hours for each diet. The correlation of proteomics and metabolomics indicators with classic laboratory parameters (BMI, HDL, LDL, cholesterol, triglyceride levels, and insulin resistance (HOMA-IR)) will be analyzed.
Probands with an Ileo- or Colostomy are assigned to consume a test meal which is either high in fat or high in carbohydrates. After the test meal samples from the stoma, urine, blood and skin are retrieved. These will be subjected to large scale analyses of microbiota and metabolite content. To get a better comparability test subjects will consume a standardized liquid diet three days before the study day.
The investigators will recruit probands with a ileo- or colostoma that are otherwise in good general health and analyse the stomal fluids for their microbiota composition. Sampling will be performed over a time span of 28 days, after 14 days probands will modify their base-line diet to a low carbohydrate diet.
This study is a randomised open label study, comparing the FIT diet with standard diet in patients with Crohn's disease treated with biologic therapy.
Obesity is a major public health problem and is constantly on the rise. Therapeutic approaches based on dietary advice, physical activity and the management of psychological difficulties are not always sufficient to achieve a lasting weight reduction. Bariatric surgery (or obesity surgery), accompanied by therapeutic education and adequate medical and dietary monitoring, can lead to significant and lasting weight loss. It is indicated as a second-line treatment for patients who have failed medical treatment, whose BMI is greater than or equal to 40 or whose BMI is greater than or equal to 35 with comorbidities (type 2 diabetes, arterial hypertension, obstructive sleep apnoea-hypopnoea syndrome, severe joint disorders). The surgeon may be very bothered by the intra-abdominal fat mass and especially by steatotic hepatomegaly (increase in the size of the liver and its fat load). Faced with this problem, various preoperative strategies such as the placement of an intra gastric balloon have been tried to decrease the size of the liver but a systematic review from 2016 indicates that a low calorie diet is preferable. Preoperative weight loss can reduce fat load and liver volume very rapidly. This meta-analysis shows that all low-calorie, high-protein diets are effective and that the optimal duration (4 weeks), compliance and tolerance are important factors for success.
A 2-arm randomised control trial (with and without labels) will be conducted to test the effects of an environmental label on food choices in a virtual supermarket. A sample of 130 participants will take part in two shopping tasks: 1/ selection of 3 products to prepare a home-made dish, and 2/ selection of a ready-to-eat dish. These two tasks will be repeated for two scenarios: 1/ participants will be asked to select the foods for usual meals, and 2/ participants will be asked to select the foods for environmentally-friendly meals. This experimental design will allow to compare food choices in the presence vs. the absence of an environmental label and to investigate whether the label is informative and likely to help individuals to choose more environmental-friendly food options when explicitly asked to do so.
