Inside the government study trying to understand the health effects of ultraprocessed foods

BETHESDA, Md. (AP) — Sam Srisatta, a 20-year-old Florida college student, spent a month living inside a government hospital here last fall, playing video games and allowing scientists to document every morsel of food that went into his mouth.

From big bowls of salad to platters of meatballs and spaghetti sauce, Srisatta noshed his way through a nutrition study aimed at understanding the health effects of ultraprocessed foods, the controversial fare that now accounts for more than 70% of the U.S. food supply. He allowed The Associated Press to tag along for a day.

“Today my lunch was chicken nuggets, some chips, some ketchup,” said Srisatta, one of three dozen participants paid $5,000 each to devote 28 days of their lives to science. “It was pretty fulfilling.”

Examining exactly what made those nuggets so satisfying is the goal of the widely anticipated research led by National Institutes of Health nutrition researcher Kevin Hall.

“What we hope to do is figure out what those mechanisms are so that we can better understand that process,” Hall said.

New video highlights NIH investment in zebrafish research

As they strive to develop new treatments for birth defects, or to prevent them, scientists at the National Institutes of Health have found a big ally in a small fish. An NIH video shows how the zebrafish, Danio rerio, is a valuable resource for scientists trying to understand the intricate process by which a fertilized egg develops into a fully formed individual, and the numerous diseases and conditions that can result when even a tiny part of the process goes wrong.

Cognitive changes may be only sign of fetal alcohol exposure

Distinct facial features not seen in many cases, NIH study finds

Most children exposed to high levels of alcohol in the womb do not develop the distinct facial features seen in fetal alcohol syndrome, but instead show signs of abnormal intellectual or behavioral development, according to a study by researchers at the National Institutes of Health and researchers in Chile.

NIH scientists identify likely predictors of hepatitis C severity

Viral evolution and host protein levels predict rapid disease progression

Scientists at the National Institutes of Health have identified several factors in people infected with the hepatitis C virus that may predict whether the unusually rapid progression of disease from initial infection to severe liver conditions, such as cirrhosis, will occur. Knowing whether a patient's condition is likely to deteriorate quickly could help physicians decide on the best course of treatment.

Renowned researcher to lead new multidisciplinary pain program at NIH

Catherine Bushnell, Ph.D., an internationally recognized pain and neuroscience researcher, has been appointed scientific director of a new research program focusing on the role of the brain in perceiving, modifying, and managing pain. Based in the National Center for Complementary and Alternative Medicine (NCCAM), part of the National Institutes of Health, this collaborative effort will complement basic science and clinical research efforts of other ongoing intramural neuroscience, imaging, and mental and behavioral health research programs.

NIH Human Microbiome Project defines normal bacterial makeup of the body

Microbes inhabit just about every part of the human body, living on the skin, in the gut, and up the nose. Sometimes they cause sickness, but most of the time, microorganisms live in harmony with their human hosts, providing vital functions essential for human survival. For the first time, a consortium of researchers organized by the National Institutes of Health has mapped the normal microbial makeup of healthy humans, producing numerous insights and even a few surprises.

NIH study finds childhood CT scans linked to leukemia and brain cancer later in life

Children and young adults scanned multiple times by computed tomography (CT), a commonly used diagnostic tool, have a small increased risk of leukemia and brain tumors in the decade following their first scan. These findings are from a study of more than 175,000 children and young adults that was led by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, and at the Institute of Health and Society, Newcastle University, England.

NIH-led study finds genetic test results do not trigger increased use of health services

Medical experts feared personal genetic test results might drive overuse of expensive medical care

People have increasing opportunities to participate in genetic testing that can indicate their range of risk for developing a disease. Receiving these results does not appreciably drive up or diminish test recipients' demand for potentially costly follow-up health services, according to a study performed by researchers at the National Institutes of Health and colleagues at other institutions.
