Flavanols, such as catechin and epicatechin, are thought to be highly beneficial for blood circulation, helping both the heart, and cognitive function. Foods high in flavanol bioflavonoids include cocoa, green tea, red wine, apples, and berries.Flavanones are found in citrus fruit, in the the white material and pulp. These bioflavonoids are what the body uses to lower blood cholesterol.

Flavonols are the most ubiquitous flavonoids in foods, and the main representatives are quercetin and kaempferol. They are generally present at relatively low concentrations of â15â30 mg/kg fresh wt. The richest sources are onions (up to 1.2 g/kg fresh wt), curly kale, leeks, broccoli, and blueberries (Table 1â).
