NCT ID NCT07650409
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study compares the effects of soy soft pretzels and wheat pretzels on inflammation in 30 men with obesity. Researchers want to see if the natural chemicals in soy can reduce chronic inflammation, which is linked to health problems like cancer. Participants will eat either soy or wheat pretzels and provide blood and urine samples to measure changes in inflammatory markers.
