Eating breakfast is a good opportunity to eat some of the nutrient-rich foods that help keep the heart in good shape. One option is whole-grain toast topped with avocado, which is rich in healthy fats and fiber. Another is oatmeal, known for its ability to lower cholesterol. Adding fruits and nuts provides additional nutrition. Eggs are another acceptable choice, ideally paired with vegetables instead of bacon, sausage, and white toast.

Mental stress ischemia occurs when emotional stress causes a decline in blood flow to the heart. The condition, which affects about one in six people with heart disease, may more than double a person's risk of heart attack. Mental stress ischemia appears to be caused in part by changes in the wall and inner lining of the heart's smallest blood vessels. Known as microvascular disease, this problem tends to be more prevalent in women. In contrast, a more common cause of chest pain is narrowing of the large arteries of the heart.

Consuming less sodium and more potassium may be linked to better heart health, according to a November 2021 study published in the New England Journal of Medicine. After controlling for other risk factors, the researchers found that for every extra 1,000 milligrams (mg) of sodium detected in the urine, there was an 18% increase in the risk of cardiovascular disease. For every extra 1,000 mg of potassium in the urine, there was an 18% decrease in risk.

A 2021 study found that a low-carb diet may not necessarily be bad for heart health, despite its high saturated fat content. However, the study period was short, and the diet used in the trial was healthier than many low-carb approaches. More research is needed to confirm the results. In the meantime, experts recommend finding a sustainable diet that provides a healthy daily mix of nutritious foods instead of solely looking at carbohydrate content.

Stir-fries feature a healthy dose of vegetables combined with lean protein and a flavorful sauce. When served over steamed brown rice, stir fries are a good example of a well-balanced, nutritious meal.

A study published Nov. 16, 2021, in PLOS Medicine found that drinking two to three cups of coffee as well as two to three cups of tea per day was associated with substantially lower risks for dementia and stroke, compared with drinking no coffee or tea.

A study published online Aug. 26, 2021, by The Lancet found that blood pressure treatment protects against heart attacks, strokes, and other major cardiovascular disease problems in people up to age 85 and possibly older. For people younger than 75, the study confirmed that people taking blood pressure medicines had 10% to 20% fewer cardiovascular disease problems. For people 75 to 84, there still was a 10% reduction. For people older than 85, the results were mixed, but there still appeared to be a benefit from blood pressure treatment.

Increasingly, tests that measure C-reactive protein are marketed to health-conscious consumers as a way of determining if they have chronic inflammation. However, the test is just one piece of evidence and should be interpreted by one's doctor. Without that expertise, a customer might not understand what the CRP test result means, and as a result might suffer unnecessary anxiety or pursue unnecessary tests. It's best to talk to one's doctor before seeking tests that measure CRP levels.
