Eating Foods Rich In Flavonoids Has Health Benefits

A new large study found that eating a flavonoid rich diet is associated with a lower risk of death. Flavonoids are compounds found in abundance in plant derived foods and beverages, such as fruits, vegetables, dark chocolate, tea, legumes, and red wine. The study followed about 56,000 people in Denmark for 23 years and found that eating higher levels of flavonoid rich foods was associated with a lower risk of death from any cause (all-cause mortality), heart disease (cardiovascular disease), and cancer.

The researchers found that there was an inverse relationship (the more one eats, the lower the risk of death), and that this relationship was strongest among cigarette smokers and people who consume high amounts of alcohol (more than 20 grams per day). Bottom line: Make sure your diet includes lots of fruits, vegetables, legumes, and dark chocolate (yes!).

By the way, while other studies do find a lower incidence of heart disease and cancer in people eating a diet rich in flavonoids, in this study they were not looking at who got the diseases, but looked at deaths. Therefore the following title is misleading. It should instead say "... protects against cancer and heart disease deaths..." From Science Daily: Flavonoid-rich diet protects against cancer and heart disease, study finds 

Researchers from ECU's School of Medical and Health Sciences analysed data from the Danish Diet, Cancer and Health cohort that assessed the diets of 53,048 Danes over 23 years.

They found that people who habitually consumed moderate to high amounts of foods rich in flavonoids, compounds found in plant-based foods and drinks, were less likely to die from cancer or heart disease.

Lead researcher Dr Nicola Bondonno said while the study found a lower risk of death in those who ate flavonoid-rich foods, the protective effect appeared to be strongest for those at high risk of chronic diseases due to cigarette smoking and those who drank more than two standard alcoholic drinks a day.

Participants consuming about 500 mg of total flavonoids each day had the lowest risk of a cancer or heart disease-related death.

"It's important to consume a variety of different flavonoid compounds found in different plant based food and drink. This is easily achievable through the diet: one cup of tea, one apple, one orange, 100g of blueberries, and 100g of broccoli would provide a wide range of flavonoid compounds and over 500mg of total flavonoids."

"Flavonoids have been shown to be anti-inflammatory and improve blood vessel function, which may explain why they are associated with a lower risk of death from heart disease and cancer."
