High consumption of ultra-processed foods linked to systemic inflammation
Peer-Reviewed Publication
This month, we’re focusing on nutrition and the powerful role it plays in our lives. Here, we’ll share the latest research on how nutrients affect the body and brain, how scientists investigate diet and health, what these findings may mean for building healthier habits, and more.

New research reveals that people who eat the most ultra-processed foods show significantly elevated levels of high-sensitivity C-reactive protein (hs-CRP) – a key marker of inflammation and a strong predictor of cardiovascular disease. The risk is particularly pronounced among adults aged 50 to 59, smokers, and individuals with unhealthy body weights. Surprisingly, physical activity didn’t appear to offset this effect: researchers found no significant difference in hs-CRP levels between sedentary individuals and those meeting exercise guidelines.
Diet doesn’t just fuel the body, it sends molecular signals that can slow down or speed up biological ageing, according to a new perspective in npj Aging (Nature Portfolio). The authors explain that biological age, a measure of functional health, can diverge sharply from chronological age and that targeted nutritional and lifestyle choices can bend the trajectory toward healthier ageing.
A recent study by the University of Eastern Finland is the first to report that the fatty acid composition of blood and the enzyme activity associated with it predict the development of bone mineral density from childhood to adolescence. The results of the Physical Activity and Nutrition in Children (PANIC) study were published in the prestigious Journal of Bone and Mineral Research.
A team of researchers at the Icahn School of Medicine at Mount Sinai has developed a new method to identify and reduce biases in datasets used to train machine-learning algorithms—addressing a critical issue that can affect diagnostic accuracy and treatment decisions. The findings were published in the September 4 online issue of the Journal of Medical Internet Research [DOI: 10.2196/71757]. To tackle the problem, the investigators developed AEquity, a tool that helps detect and correct bias in health care datasets before they are used to train artificial intelligence (AI) and machine-learning models. The investigators tested AEquity on different types of health data, including medical images, patient records, and a major public health survey, the National Health and Nutrition Examination Survey, using a variety of machine-learning models. The tool was able to spot both well-known and previously overlooked biases across these datasets.
