A 2025 study suggests that very low levels of lithium in the brain might be linked to Alzheimer's disease. In mice, certain lithium supplements seemed to protect memory and the brain. But scientists don't yet know if lithium pills are safe or helpful for people.

A 2026 study suggested that people who stop taking weight-loss medications rapidly regain weight and lose heart health benefits associated with the drugs.

People sometimes have difficulty knowing if they should seek care at an emergency room or an urgent care center. Urgent care centers can treat health problems that don't endanger lives, while emergency rooms can treat serious or life-threatening problems.

For people who are concerned they're drinking too much but don't want to give up alcohol entirely, the Sinclair Method may help. It involves taking naltrexone (a drug that dampens alcohol's euphoric effects) an hour or two before drinking.

Bone broth, made by slowly simmering animal bones with seasonings, offers rich flavor, more protein than regular broth, and amounts of minerals. Choosing low-sodium varieties or making it at home helps limit additives and salt.

Daily nasal irrigation (nasal rinses) may reduce symptom severity and the duration of a cold. It can also relieve the congestion caused by sinus infections and allergies. By means of a squeeze bottle, neti pot, or battery-powered system, saline is inserted into one nostril and flows out the other.

Dragon fruit stands out for its striking look, mild sweetness, and a mix of fiber, minerals, and antioxidant compounds. It isn't a magic "superfood," but it's a healthy, colorful way to help people eat more fruit in fun new ways.

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.

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.
