Native Hawaiian adults experience mobility limitations—including challenges with agility, gait, balance and fall risk—at significantly higher rates and at younger ages than other major racial and ethnic groups in Hawaiʻi, according to new research from the University of Hawai’i at Mānoa’s Hā Kūpuna National Resource Center for Native Hawaiian Elders.

Kombucha has become part of the wider boom in gut-friendly foods and drinks. But a major heart health charity is urging consumers to look more carefully at what these products actually contain.

A new perspective paper published in Frontiers in Nutrition argues that current public health recommendations for physical activity and protein intake are designed to prevent deficiency rather than maximize long-term health, independence and quality of life. The paper explores first-principles questions: How much protein should you have? What exercises should you be doing? What does the latest science tell us?

In Toy Story 5, Woody, Buzz, Jessie and the gang are up against a new challenge: Bonnie’s tablet. Even Rex, the toy dinosaur, is worried about going extinct again.

Liver cancer is one of the fastest-rising causes of cancer-related deaths in the UK and the third-leading cause of cancer deaths worldwide.

American Indians and Alaska Natives living below the poverty line face sharply higher rates of food insecurity than other impoverished adults—nearly 4 in 10 lack consistent access to a healthy diet.

Women who lift weights may have a lower risk of major heart disease, especially when combined with aerobic exercise, according to a new study published in JACC. Findings show that heart health is better understood by looking at overall movement habits, rather than focusing on single behaviors alone, and resistance training can result in additional health benefits when incorporated into an active lifestyle.

Yo-yo dieters who struggle to lose weight and keep it off may achieve better results by following an intermittent fasting diet, rather than traditional calorie counting. An Adelaide University study focusing on the psychological aspects of both intermittent fasting and calorie restriction compared the effects the diets had on eating behaviors, mood, sleep and quality of life. The research is published in the journal Clinical Nutrition.

Smartphone apps, fitness trackers and wearable devices help people with heart disease get more physical activity in their daily lives, according to an analysis of previous research published in the Journal of the American Heart Association.

As recently as the mid-20th century, aging was described by Nobel Prize laureate Peter Medawar as “an unsolved problem in biology.” Today, scientists can analyze the activity of thousands of genes in individual cells, identify genetic variants associated with longevity, study molecular pathways affecting lifespan, and estimate biological age using epigenetic clocks. Experimental therapies using senolytics—compounds that eliminate some senescent cells—have also emerged. Paradoxically, however, the more we know about the biology of aging, the more clearly we see how complex this process is.

A new article published in Globalization and Health warns that the rapid rise of GLP-1 weight-loss drugs in high-income countries could have unintended consequences for food environments in low- and middle-income countries.
