Over the past decade, nutrition experts have shifted away from recommending a low-fat diet to focusing more on an overall healthy dietary pattern. This eating style, which includes lots of plant-based foods, is naturally low in saturated fats. Found mainly in meat and dairy products, saturated fat can boost levels of harmful LDL cholesterol, a key contributor to heart disease. Cutting back on all types of fat does not necessarily translate into a diet that lowers cardiovascular risk. The plant-centric Mediterranean eating pattern, which is rich in healthy unsaturated fats found in nuts, seeds, and olives, has the best evidence for lowering heart disease risk.

Coronary artery calcium scans tend to be quite accurate. Unlike some other imaging tests, the results are unlikely to be either falsely negative or falsely positive because the results are literally black and white (the calcium shows up as white on the scan).

Tofu may be good for the heart. A study published in March 2020 in the journal Circulation found that people who ate at least one weekly serving of tofu or another food containing isoflavones (a compound found in soybeans and other legumes) had an 18% lower risk of developing heart and blood vessel disease than people who ate these foods less than once a month. These foods appeared particularly beneficial to premenopausal women and women who had gone through menopause but weren't using hormone replacement therapy. Experts recommend substituting these foods for less healthy protein options such as red or processed meats.

Many manufacturers are changing the ingredients in over-the-counter decongestants. How the new and old ingredients can affect your health, especially if you have heart disease.

Buckwheat is a pyramid-shaped seed that’s used like a grain and featured in different forms in cuisines around the world. Buckwheat contains substances that may help improve blood vessel health and lower cholesterol.

Higher blood levels of omega-3 fatty acids—specifically, eicosapentaenoic acid (EPA) from fish and alpha-linolenic acid (ALA) from plants—may help lower the odds of a poor prognosis in the years following a heart attack. Fatty fish such as salmon and mackerel are good sources of EPA. Flaxseeds, chia seeds, and walnuts are good sources of ALA, which is also found in soybean and canola oil.

In people with obesity, a high-dose weekly injection of the diabetes drug semaglutide caused a 15% weight loss and improved other heart-related risk factors. Semaglutide works by mimicking a substance called GLP-1, which is made naturally by the gut and the brain. It prods the pancreas to release insulin when blood sugar rises too high, reduces appetite, and makes people feel full following a meal.

People should be cautious about weight-loss diets that restrict a specific category of food (such as carbohydrates, fats, or even animal products) without focusing on the overall quality of the foods. Diets with lots of ultra-processed foods or red meat may contribute to poor heart health. But people can lose weight on less-extreme versions of either low-carb or low-fat diets, as long as they focus mostly on unprocessed or minimally processed foods.

People who increase their drinking in later midlife—consuming 21 or more drinks per week—may raise their risk of atrial fibrillation compared with those who maintain low to moderate alcohol intake.
