Inside the NIH Study: Eating Only Ultraprocessed Foods for a Month for Science.

Sam Srisatta, a college student, lived in a hospital for a month to help scientists study food. He ate different foods, like chicken nuggets and salad, so scientists could learn about ultraprocessed foods.

Ultraprocessed foods are common in the US and are thought to be unhealthy. Scientists want to know if these foods make people eat more and gain weight.

Sam wore special devices to track his movement and ate specific meals prepared by the scientists. He also spent time in a special room that measured his body's use of food and air.

Early results suggest that people eat more calories when they eat ultraprocessed foods. However, some scientists believe that longer studies are needed to confirm these findings.

Sam's experience made him want to learn more about the effects of processed foods on health. He believes that it's better to avoid processed foods, a view shared by many.
