Consuming flavonoid-rich items such as apples and tea protects against cancer and heart disease, particularly for smokers and heavy drinkers, according to new research from Edith Cowan University (ECU).

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.

No quick fix for poor habits

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.

“These findings are important as they highlight the potential to prevent cancer and heart disease by encouraging the consumption of flavonoid-rich foods, particularly in people at high risk of these chronic diseases,” she said.
