Flavonoids, a class of micronutrients found in most plant foods, have been shown to possibly reduce the risk of dementia by protecting brain cells, improving blood flow, and reducing inflammation. Following a plant-based diet and aiming for at least five to nine servings of fruits and vegetables per day can help people get sufficient amounts of flavonoids.

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).

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.

Eating an unhealthy meal every now and then may not cause problems for generally healthy people. This may mean eating a healthy diet 90% of the time and splurging 10% of the time.

Instead, one should follow a healthy diet on most days, and indulge only occasionally.

Probiotics are good bacteria that keep the gut healthy and help fight infections and inflammation. Some research suggests that certain probiotics help relieve symptoms of gut-related conditions like inflammatory bowel disease and irritable bowel syndrome. Fermented foods are the best sources of probiotics, such as yogurt, pickles, sauerkraut, and sourdough bread.

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.
