How socioeconomic status shapes food choices and what it means for public health

A new Journal of Marketing study reveals why low-socioeconomic status (SES) consumers continue to face challenges in adopting healthier diets despite the increased efforts to make healthy foods affordable and accessible. Researchers uncovered that low-SES individuals prioritize fillingness over healthiness when making food choices and are more likely to believe that healthy foods are less filling and less tasty, compared to their high-SES counterparts.

Medical infusion bags can release microplastics, study shows

Microplastics have been found almost everywhere that scientists have looked for them. Now, according to research published in Environment & Health, these bits of plastic—from 1 to 62 micrometers long—are present in the filtered solutions used for medical intravenous (IV) infusions. The researchers estimate that thousands of plastic particles could be delivered directly to a person’s bloodstream from a single 8.4-ounce (250-milliliter) bag of infusion fluid.

Proposed legislation would provide crucial funding for endometriosis research

The Endometriosis CARE Act, which was introduced in 2022, seeks to deliver $50 million annually to advance research and expand access to treatment for this condition in which tissue similar to the uterine lining grows outside the uterus, often causing pain, heavy periods and potential fertility issues. It affects more than one in 10 reproductive-age women and currently, there is no known cure.

A woman’s heartbeat changes across her menstrual cycle, offering insights into heart and brain health

Rhythmic changes, driven by hormonal fluctuations, offer a unique window into the intricate connection between the female brain and heart. In a new paper published in Science Advances, Max Planck researchers Jellina Prinsen, Julia Sacher and Arno Villringer outline how these naturally occurring variations might influence stress, mood, and long-term cardiovascular and neurological health.
