According to a recent research published in Journal of Nutrition, consuming Flavanols found in certain whole fruits and vegetables can reduce risk of type 2 diabetes by almost 30 percent. Flavanols is part of the phytonutrient group known as flavanoids which possess high anti-inflammatory and anti-cancer properties. The abovementioned study found that a particular flavanol known as myricetin produced the most positive results in reducing diabetes risk. Another study published in US National Library of Medicine found that myricetin improves insulin resistance by decreasing obesity and serum proinflammatory cytokine levels in mice.
While flavanols can be found in most fruits, myricetin in particular is best obtained from these sources: sweet potato leaves, parsley, black currants, cranberries, broad beans, rutabagas and blueberries.
