Paint Your Heart Healthy with Flavonoids
Eating more fruits and vegetables is also key to preventing heart disease
Fix it before it breaks
Preventing heart disease is easier than curing it. We already know a lot about how to keep the heart happy, like
Eating more fruits and vegetables is also key to preventing heart disease. These foods are rich in magnesium, potassium, and fiber that can help regulate blood pressure and blood sugar levels.
Brightly colored fruits and veggies are also high in flavonoids, plant compounds that give foods such as oranges, broccoli, and so on their characteristic hues. Flavonoids have anti-inflammatory and antioxidant actions in the body. They also inhibit the oxidation of LDL ("bad") cholesterol and encourage blood vessel walls to relax, helping to lower blood pressure.
As part of the Cancer Prevention Study II Nutrition Cohort, researchers from the American Cancer Society and Tufts University investigated how different types of flavonoid compounds in the diet might protect against death from heart disease. In the study, 38,180 men and 60,289 women (average age 69 and 70, respectively) gave detailed information about their diets. The amount and types of dietary flavonoids were estimated for each participant. For the next seven years, the participants were followed and deaths due to heart disease were recorded.
"Even relatively small amounts of flavonoid-rich foods may be beneficial for reducing risk of fatal cardiovascular disease," commented the researchers.
Brighten your plate for a happier heart
Getting more flavonoids into your diet is as easy as blueberry pie. Just aim for a rainbow of colors throughout the day. You don't have to get them all in at every meal, but when you're planning your five-a-day of fruits and vegetables, make sure they're not all in the white family.
Raspberries, strawberries, apples, blueberries, green tea, black tea, dark chocolate, red grapes, purple cabbage, red wine, oranges, grapefruit, kale, broccoli, onions, and leeks are all loaded with heart-healthy flavonoids.
Parsley, thyme, oregano, celery, and green chili peppers are rich sources of the subclass of flavonoids called flavones. These are the ones that may be especially helpful for women.
