Brain scans and sugar-free sweeteners in healthy young adults
This study uses brain scans (MRI) to look at how long-term use of sugar-free sweeteners (like those in diet sodas) affects the brain. It may help us understand why some people consume more of these sweeteners and how they influence appetite or food choices.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be between 18 and 30 years old and in good health.
- Have a body mass index (BMI) in the healthy range (18.5 to 24.9).
- Eat or drink either very little or a lot of sugar-free sweeteners (like diet sodas).
- Be able to have an MRI brain scan (no metal implants, pacemakers, or severe claustrophobia).
- For women: use effective birth control during the study (unless not of childbearing potential).
- Not have any chronic conditions, addiction issues, or eating disorders.

This study looks at how non-nutritive sweeteners (like the ones in diet sodas) affect your health. You'll follow a special diet for a few weeks, and researchers will check things like blood sugar and metabolism.
This study tests how different sweeteners affect your body if you have a sweet tooth. If you are generally healthy and like sweet foods or drinks, you may be able to join.
This study looks at how brain responses and metabolism affect your desire for carbohydrates. Volunteers have MRI scans and taste tests at the Fralin Biomedical Research Institute in Roanoke.
This study uses MRI scans to measure how your brain uses energy and how certain brain chemicals are made. It’s for healthy adults and can help researchers understand normal brain chemistry and metabolism.
This study tests three different taste-based diets to see which one best helps people cut down on free sugars (the sugars added to foods and drinks). It is for adults who eat a lot of sugar and live in the South of England.
This study looks at whether the way the brain uses sugar (glucose) in people with type 2 diabetes can improve, and whether changes track with tighter diabetes treatment. You may get brain scans (MRI/MRS) and diabetes monitoring to see if there’s “reversibility” in the brain’s sugar transport.
