Heart Healthy
According to Tufts University, blueberries have been shown to improve blood pressure and reduce arterial stiffness. Other research suggests that blueberries can help improve cholesterol levels; specifically reducing oxidation of the bad LDL cholesterol.
Brain Boost
Blueberries are rich in polyphenols called anthocyanins, which give them their distinctive color. These anthocyanins can cross the blood brain barrier and might decrease the oxidative stress that occurs with aging, reduce inflammation and increase signaling between neurons. What’s more, Tufts University scientists have found that the addition of blueberries to a diet can improve short-term memory, navigational skills, balance and coordination.
Diabetes and Cancer
Although blueberries fall a little higher on the glycemic index than other berries, they may be beneficial for blood sugar regulation, according to one study. In other studies, blueberries have been shown to decrease free radical damage to DNA that can lead to cancer and to inhibit the growth of cancer cells.
