A narrowed aortic valve (aortic stenosis) affects about one in 20 people over age 65. Medical therapies for treating this progressive disease are under investigation, and a recent study explored the potential benefits of proactive valve replacement.
Carotid artery stenosis, which happens when fatty plaque accumulates in neck arteries that supply the brain, leaves people vulnerable to a stroke. Intensive drug therapy may forestall the need for invasive procedures to treat this problem.
Retainers have benefits beyond keeping a nice smile after braces, aligners, or other orthodontic treatment. The appliances help maintain teeth alignment, protecting them from extra wear and tear. Several types of retainers can help. The choice depends on a person’s needs and habits.
Cutting back on ultra-processed foods that have little nutritional value can help protect your health, but you don’t have to make everything from scratch either. Seek out less-processed versions of your favorite foods at your supermarket to turn into healthy meals with minimal effort.
The new Dietary Guidelines for Americans are a mixed bag. While their advice to choose whole foods, avoid highly processed foods, and limit added sugars is sound, their promotion of animal-based foods like meat and full-fat dairy products is less supported by rigorous scientific research.
A 2025 study suggests that polyphenols, found in a wide range of plant foods, may have long-term benefits for the heart. Over an average of 11 years, people whose diets contained the most polyphenol-rich foods ranked lowest on scores of heart disease risk.
While many people may think that a more sustainable diet is more expensive, a 2025 study suggests that in fact, foods with smaller environmental footprints tend to cost less. Choosing fewer animal-based foods and more plants can be better for health, budgets, and the planet.
Dietary changes can make a big difference for people with gastroesophageal reflux disease (GERD). Foods to limit or avoid include chocolate, onions, and tomato sauce. Adjusting eating habits—by eating smaller portions, for example—might also help people avoid heartburn and other symptoms.
Parkinson’s disease symptoms tend to develop gradually and can be mistaken for normal aging. Early movement-related signs include tremor in one hand, slower movements, mild balance and gait changes, and muscle stiffness. Other clues include loss of smell, sleep changes, and constipation.
Somatic workouts involve paying attention to internal sensations and responses during physical movements. These movements help people become more aware of how their body moves. Somatic workouts can reduce pain and muscle tension and calm anxiety.
