A type of flavonoid called anthocyanin gives blueberries many of their health benefits. Flavonoids are plant compounds that often have a powerful antioxidant effect.
Anthocyanin is responsible for the blueberry's characteristic blue color. It also contributes to the numerous advantages of blueberries.
Consuming a variety of fruits and vegetables has long been associated with a reduced risk of many lifestyle-related health conditions.
Many studies have suggested that increasing consumption of plant foods such as blueberries decreases the risk of obesity, diabetes, heart disease, and overall mortality. Plant foods may also promote hair and skin health, increased energy, and overall lower weight.
Freezing blueberries is often discussed by experts. It is often said that the freezing process can diminish the potency of the blueberry's health benefits. One study showed that over the course of 6 months in storage, the anthocyanin degraded by 59 percent.
However, this is not confirmed, and different sources take different stances on whether freezing blueberries reduces their impact on health. When in doubt, buy fresh, organic blueberries.
Although more research is needed, blueberries are strongly linked to various different elements of healthful living.
