Does smelling a madeleine cookie affect blood sugar control?
Part of Brain & nervous system, Hormones & metabolism clinical trials.
This study tests whether smelling a food odor (like a madeleine cookie) can trigger a natural insulin release that helps control blood sugar. It aims to see if this effect differs based on how sensitive your body is to insulin.
Summary written for real people, not researchers, by Clin2.

This trial studies how different types of starch (carbohydrates) affect blood sugar control, inflammation, and gut health in people with insulin resistance. You may benefit if you are overweight, have insulin resistance, and are willing to follow a specific diet for 2 months.
This study uses brain scans to see how the brain reacts to food smells and tastes in women with long-lasting anorexia nervosa. It aims to understand the brain's role in anorexia, which could help improve treatments.
This study looks at how belly fat and nerve signals affect food preferences. You'll taste and smell different things and have a check-up visit at a research center in Quebec City.
This study looks at how taste and smell may differ in people with obesity compared to healthy-weight individuals. It aims to understand why some people perceive flavors differently, which could help develop better treatments for weight management.
This study looks at how body weight and insulin sensitivity (how well your body uses sugar) affect the brain's reward and decision-making areas. You'll have brain scans and drink special study drinks to see how your brain responds.
This study looks at how very small particles in the body (“extracellular vesicles”) relate to insulin action and how the body handles sugar. It may help researchers understand why some people have better or worse insulin responses.
