What counts as flavonoids?
Flavonoids are mainly found in fruits, vegetables and other plant-based foods but also crop up in red wine and dark chocolate.
“The general rule is that the more colourful a fruit or vegetable is, the higher the level of flavonoids it contains,” explains Holland and Barrett.
As the health body explains, there are five main types of flavonoids that contain various benefits, each of which are found in different foods.
These are:
Flavanols
They are commonly found in kale, peaches, tomatoes, onions, lettuce, tea, grapes, red wine, blueberries, and other fruit.
Flavan-3-ols
Nutrient-rich flavan-3-ols can be found in lots of foods. These include white, green, and black tea, as well as apples, grapes, strawberries, blueberries and even cocoa products, such as dark chocolate.
Flavones
Like all flavonoids, flavones are praised for their antioxidant properties. Citrus fruits like lemons, grapefruit, limes and oranges are familiar sources of flavones as are celery, parsley, and hot peppers.
Isoflavones
More research is needed around isoflavones, but experts believe this type of flavonoid can help with the body’s hormone balance. Isoflavones are richest in soy products along with peanuts, pistachios, and fava beans.
Anthocyanins
The last flavonoid on our list, anthocyanins. You’ll commonly find these flavonoids in the outer skin of various berries, including red and purple grapes, blackberries, strawberries, blueberries, cranberries and even red wine.
