Fruit of the month: Dried fruits

Dried fruits such as raisins, dates, and figs are good sources of potassium, fiber, and other nutrients. A serving size of these calorie-dense treats is just a quarter-cup.

Grain of the month: Brown rice

Compared with white rice, brown rice contains much higher amounts of fiber, certain B vitamins, magnesium, potassium, and iron. Research suggests that swapping white rice for brown rice may improve blood sugar levels and help with weight control.

POTS: Diagnosing and treating this dizzying syndrome

Most of us don't think twice about standing up, but for people affected by postural orthostatic tachycardia syndrome (POTS), standing can provoke lightheadedness and a racing heartbeat. While some people with POTS will require medications, most will improve with some specific dietary and behavioral changes.

What is POTS — and what triggers it?

Postural orthostatic tachycardia syndrome (POTS) is a condition characterized by lightheadedness or dizziness when standing and a racing heart. The underlying cause is not known, although it sometimes follows bedrest after injury or illness. Recently, POTS has been diagnosed in some people who have had COVID-19.

A brief bout of anger may be bad for your blood vessels

A short episode of anger may have adverse effects on the cells lining the blood vessels, according to a 2024 study. The findings may help explain the long-observed link between negative emotions and an increased likelihood of cardiovascular problems.

Counting steps as good as time tracking for monitoring heart health

Advice about the amount of physical activity required to stave off heart disease and other chronic ailments is usually expressed as a time-based goal. But counting steps may be just as useful, according to a 2024 study.

All types of alcohol appear to raise blood pressure

A 2024 study suggests that the more alcohol people drink—whether they imbibe beer, wine, or hard liquor—the higher their blood pressure.

Rethinking HDL cholesterol

The scientific understanding of HDL cholesterol has evolved in recent years, and many cardiologists now believe that HDL may be more of a bystander rather than a "good guy" that helps lower heart disease risk. While some types of HDL are great at plucking excess cholesterol from LDL and artery walls (a process referred to as reverse cholesterol transport) other types of HDL don't do this. In clinical trials, medications to raise HDL levels—including a drug specifically designed to improve reverse cholesterol transport—have not succeeded in lowering heart attacks and strokes.
