A major Harvard study adds more evidence that a healthy diet may protect your brain. Older adults who ate the most ultra-processed foods were found to have substantially higher risks of dementia and cognitive decline, while those eating more minimally processed foods had lower risks.

The DASH diet is a flexible, science-backed eating plan proven to lower blood pressure, while also reducing risks of heart disease, diabetes, cancer, and cognitive decline. Emphasizing vegetables, fruits, whole grains, and low-fat dairy products, it’s a healthy way to eat that suits almost everyone.

For people managing a chronic illness or recovery, medically tailored meals—home-delivered and dietitian-planned—can help. Research shows they improve health outcomes, reduce hospitalizations, and save billions in health care costs. Programs range from full meal delivery to grocery boxes and produce vouchers.

Most Americans fall short on their intake of potassium, a vital but overlooked nutrient. People can boost the level of potassium in their body by eating more plant foods, especially beans, potatoes, leafy greens, and fruit, and by cutting back on ultra-processed foods.

Staying at home during a power outage can be risky for your health. To be safe, take steps to maintain power for essential medical equipment, store medications properly, and prepare for other hazards.

People who aggressively lower their high blood pressure not only help their heart health, but also may protect their brains from cognitive decline in the process, according to a 2025 study.

People who follow a healthy lifestyle can still have the early stages of coronary artery disease (CAD), the most common type of heart disease. There are many ways people can find out if they have CAD. This includes paying attention to whether exercise causes discomfort, doing a 10-year heart risk assessment, and seeing their doctor for diagnostic testing, such as a coronary artery calcium scan, a resting electrocardiogram, a walking stress test, or an echocardiogram. A doctor uses this information to determine the best treatment path.

A 2025 study found that morning coffee drinkers faced lower odds of dying from cardiovascular disease-or any cause-over a 10-year period compared with people who drank coffee all day or people who didn't drink coffee at all.

The body roundness index-defined as height in relation to waist circumference-may be a good way to predict a person's risk of cardiovascular disease.

The latest diabetes guidelines now recommend continuous glucose monitors for many people with type 2 diabetes. The real-time data from these devices may help reduce heart-related risks in people with diabetes by helping to reduce blood sugar, cholesterol, blood pressure and body weight.
