Filter by:The study team is inviting 13 healthy people to complete a study to explore how calcium affects hormones and bones after eating. Participants will be asked to complete two study visits within eight weeks. Before each visit, participants will be asked to not eat or drink (except water) for 9 hours. At each visit, participants will eat the same meal provided by the research team. Along with their meal, they will take a pill - in one session, this will be a calcium supplement, and in the other, a placebo (a pill with no calcium), but they won't know which one they are taking at which session. A phlebotomist will draw blood before the meal and pill, then again several times after eating. Blood draws will take place over three hours. During that time, participants will complete questionnaires about health, diet, and physical activity. Blood will be analyzed to check on various health indicators, like bone health markers and certain hormones, to see how they change after the meal. The difference in these health indicators between the calcium and placebo sessions will help the study team understand the impact of calcium on health after eating. This could help increase knowledge of the impact of calcium on hormones and bone health.
When a meal is eaten, nutrients activate the release of hormones from the bowel into the blood stream. Normally there is a large amount of hormone released, which tells the brain that an individual is full and to stop eating. When people gain weight and become overweight or obese, these hormone signals are reduced, resulting in these people eating more and gaining more weight. This study is investigating mechanisms which may break this cycle by using particular nutrients to restore reduced hormone levels.
Diabetes contributes significantly to the burden of disease in Norway and cardiovascular disease is the main cause of mortality. Both lean and fatty fish are shown to have beneficial health effects. In addition to omega-3 fatty acids, fish contain potential health-promoting components such as taurine, vitamin D, vitamin B12, iodine, selenium and more unspecified components such as bioactive peptides. With the expected growth in the aquaculture sector, more protein-rich by-products will become available. The overall aim of this project is to investigate physiological and molecular effects of fish protein in the form of salmon fishmeal compared to whey in a human intervention study with regard to carbohydrate- and fat metabolism, endocrine factors and inflammation. The investigators will include healthy subjects to a randomized controlled cross over study. The subjects will receive a single, oral dose of fishmeal or whey. Blood samples are taken before (fasting) and 30 and 60 minutes after intake. The molecular effects of fishmeal and whey are investigated ex vivo. This is done by incubating human cell lines (i.e hepatocytes, adipocytes, epithelial cells) with fasting and postprandial serum from the participants.
