Filter by:The Cohort on Plant-based Diets (COPLANT) study is a multi-centre cohort study that starts baseline recruitment from 2024 to 2027 with approximately 6,000 participants in Germany and Austria. The COPLANT study focuses on vegan (no animal products), vegetarian (no meat and fish, but dairy products and eggs), pescetarian (no meat, but fish) and omnivorous (mixed diet including all possible animal products) diets. The aim of the COPLANT study is to gain new insights on health benefits and risks as well as social, ecological and economic effects of different plant-based diets in comparison to a mixed diet. In addition to a detailed dietary survey using an app adapted to the needs of this study, the baseline examination includes measurements of body composition, bone health, cardiovascular risk factors, diabetes risk, contaminants and lifestyle. For the basic laboratory program, fasting blood, 24-hour urine collection and a stool sample are taken from all study participants. Furthermore, specific aspects of dietary behavior, physical activity and other lifestyle factors are collected via questionnaires. Follow-up studies are planned at intervals of 5, 10 and 20 years after the baseline visit.
The study consists of two arms: 1) intervention group using eggs as supplementary food given from 2nd trimester of pregnancy to birth, and 2) observational group of pregnant mothers. it aims to assess the effectiveness of improving dietary quality during pregnancy on the epigenetic and stunting related outcomes (growth and development) in infants, who will be followed up until 24 months old
Obesity is a chronic disease in which accumulation of excess body fat can result in impaired health. In cases of severe obesity, weight loss surgery can be necessary as a treatment. There are different forms of surgery but the common basic principle is to restrict food intake and decrease the absorption of food in the stomach and intestines. As a consequence, there is a higher risk of developing nutrient deficiency after surgery and supplementation of protein, vitamins, and minerals can be necessary. This study evaluates intakes of protein, vitamins, and minerals in patients with weight loss surgery and compares them to recommended intakes. Further, this study looks at the role of age, sex, and socioeconomic status in this context.
The aim of the study was to evaluate the effects of hypotensive treatment combined with a higher zinc supply in the diet and supplements on the mineral status and selected biochemical parameters of newly diagnosed hypertensive patients on monotherapy.
Patients undergoing bariatric surgery often develop new vitamin and/or mineral deficiencies or exacerbate prior deficiencies after surgery. Several bariatric supplement products exist including oral tablets and transdermal patches. The purpose of this study is to observe the concentrations of serum micronutrients and determine how many deficiencies develop in patients who use a transdermal patch.
Older adults are susceptible to vitamin and mineral deficiencies for a variety of reasons and have an increased demand for many of these micronutrients. Multivitamin/multimineral supplement offer a simple way for adults to improve nutrient intake, but their ability to measurably affect micronutrient status in older adults has never been explored. This study intends to recruit healthy, non-smoking men aged 65 years or older. After meeting entry criteria, subjects will be required to restrict the use of supplements and/or fortified foods. Two months after these restrictions have begun, subjects will come to the clinical research center to take cognitive tests, undergo activity monitoring, provide blood samples for nutrition testing, and take food frequency questionnaires. Subjects will then be randomized into one of two groups - one consuming a multivitamin/multimineral supplement (Centrum Silver Mens Formula); another consuming an inert placebo tablet. Subjects will consume 1 tablet each day for six months. After this period, subjects will return to the clinical research center and repeat cognitive tests, activity monitor, blood sampling, and food frequency questionnaires. These data will be assessed to determine if multivitamin consumption results in changes in various nutrients versus taking a placebo (primary outcomes), and may results in changes lipid and lipoprotein profiles, metabolic health, inflammation, blood pressure or cognitive function (secondary outcomes). The investigators expect that results of this study will add to the general understanding if multivitamin/multimineral formulas can improve nutrition status of older adults, and therefore have the capacity of altering markers of health.
