Measuring DNA from food in wastewater could offer a novel method for tracking dietary patterns, providing valuable data to inform nutrition policy, according to new research from NIH Research Matters.
This innovative approach provides snapshots of community-wide dietary habits. In other findings, researchers discovered that a high-fat diet in mice amplifies nerve signals between certain lung cancers and the brain, resulting in reduced appetite and weight loss.
Additionally, new insights into antibiotic resistance reveal that some bacteria share proteins, enabling others to survive antibiotic treatments. These diverse studies highlight ongoing efforts by the National Institutes of Health to advance understanding in public health and medical science.
