How did students’ diets and behavior change after the expiration of a pandemic-era universal free school meal program in 2022? Researchers asked teachers for their observations of the impact on students and found that teachers perceived more student hunger and stress, increased consumption of junk food and reduced focus in the classroom among the negative outcomes.

As aging populations drive rising global health care demands, finding scalable ways to prevent cognitive decline has become a public health priority. While intensive clinical trials have shown that multidomain lifestyle interventions can protect brain health, translating these resource-heavy protocols into everyday municipal practice remains challenging.

People have been making health claims about yogurt for hundreds of years.

Finishing a tough workout always feels good. That is, until a few hours later, when those uncomfortable muscle aches start setting in. This discomfort can linger for days—making easy, everyday tasks a challenge.

Snacking, it turns out, is not all about chips, cookies and chocolate. Dutch millennials often consume nutritious foods, such as fruit, bread and yogurt, between their main meals. This is one of the findings from the doctoral research of Mariëlle de Vaal. Moreover, snacking behavior revolves not only around the food or drink consumed, but also around people’s motives and the situation in which they eat or drink.

A team of researchers from INRAE, Inserm, Sorbonne Paris Nord University, Université Paris Cité and the CNAM has published the first study exploring the association between eating jetlag and the risk of cardiovascular disease. Eating jetlag refers to the difference in the timing of meals between weekdays—when mealtimes are often shaped by work schedules—and weekends or days off. This shift in eating patterns may disrupt the body’s biological rhythms and could have implications for cardiovascular health.

Caregivers play an essential role in helping children maintain adequate nutrition during their cancer treatment. But treatment-related side effects, such as nausea and poor appetite, can make feeding a child particularly challenging. Nutrition priorities also shift throughout treatment and beyond.

The cells of our body are frequently exposed to hazards that can damage them, cause them to malfunction or kill them. Yet they have defense systems that can sometimes be strengthened by small doses of stress, a phenomenon known as hormesis. Scientists are investigating whether food compounds and medicines can harness these protective processes to benefit health.

You finish a workout feeling pleased with yourself. But an hour later, your legs feel heavy, climbing the stairs seems impossible and all you want to do is sit down.

Deep inside the brain, a master clock synchronizes thousands of molecular clocks scattered throughout the body, and together, they anticipate signals such as the rising sun, the coming night and the daily rhythms of life. But Texas A&M University researchers have discovered that the liver is also listening for another signal, one tuned to something much closer to home: the dinner bell.
