What people choose to eat has a big impact on their cardiovascular health. The dietary habits of the nation as a whole also have a major effect on the country's economic health. About 45% of the costs associated with heart disease, stroke, and diabetes is related to unhealthy diets. The dietary habits that appear to have the biggest effect are not eating enough nuts, seeds, and seafood omega-3 fatty acids. Among foods to avoid, sugary beverages and processed meats seem to contribute the most to higher costs. Each year, unhealthy diets cost the United States an average of about $300 per person in medical costs, which translates to $50 billion nationwide.

Some research says taking a daily fish oil supplement can reduce the risk of heart attacks and strokes, while other studies say the evidence remains thin. While fish oil is the best source of omega-3 fatty acids (essential nutrients that the body cannot make on its own),  taking an over-the-counter fish oil supplement probably provides no extra heart benefit beyond a well-balanced diet that includes plenty of omega-3-rich fatty fish, nuts, and seeds.

A recent review found not only that coffee won't harm cardiovascular health or raise the risk of cancer, but it may actually have some health benefits. These include a lower risk of diabetes, and certain cancers, such as liver, and endometrial cancer. Many of these benefits may come from plant chemicals found in coffee.

For decades, high intake of fat was thought to cause weight gain, heart disease, and maybe even cancer. The solution? Go low-fat, which often meant consuming more carbs and more sugar. But nutritionists now suggest people actually need adequate amounts of "good" unsaturated fat, and less "bad" saturated fat, for optimal health. Following popular heart-healthy diets, like the Mediterranean and MIND diets, and making simple dietary changes can help people get adequate amounts of good fats.

Exposure to microscopic particles called PM_2.5 in air pollution may increase a person’s risk of heart attack, stroke, and heart rhythm disorders. The tiny particles pass from the lungs into the bloodstream, triggering inflammation and other cell-damaging processes. Air pollution comes mainly from coal-fired power plants, industrial factories, and motor vehicles. To limit exposure, people should try to avoid exercising outdoors near busy roads or industrial areas.

People who've never experienced wooziness should call 911 if the symptom comes on suddenly or severely, especially if it's accompanied by other symptoms. However, a person who has experienced wooziness before or been unwell recently should sit down, have a drink of water or juice, and rest for 10 to 15 minutes. If the feeling of wooziness persists, if other symptoms develop, or if it's hard to get up without feeling faint, one should call 911.

Stroke is the most common cause of aphasia, a language-based brain disorder that can affect speaking, understanding, reading, and writing. But the brain has the ability to rewire brain cells and recover lost function through a process known as neuroplasticity. Therapy with a speech-language pathologist facilitates this recovery, which is greatest in the first several months after a stroke. Stroke survivors who keep working on their language processing problems can continue to improve for years.

People who have had shingles have a 30% increased risk for heart disease and stroke, says a new Harvard study. Learn more about the risk.

Sometimes people miss the symptoms of life-threatening conditions such as a heart attack, a stroke, atrial fibrillation, or a pulmonary embolism. To detect the warning signs, people should pay attention to sudden, new symptoms, especially if they include shortness of breath, chest pain, heart palpitations, lightheadedness, confusion, weakness, fatigue, fainting, or a terrible headache. Someone experiencing any of these symptoms should call 911. If symptoms aren't sudden or intense, and people aren't sure if they warrant emergency help, they should call their doctor.

A 2022 observational study that included more than 200,000 people found that those who'd had shingles at some point had a 30% higher long-term risk for a major cardiovascular event, compared with people who didn't have shingles.
