Native to North America, blueberries have been part of the human diet for more than 13,000 years, long before they were formally recognized for their healthy and anti-cancer effects. Blueberries are among the best foods you can eat, and I recommend eating them every day. I have created easy, healthy recipes using blueberries, plus non-dairy milk, ground flax seed, and other nutrient-dense, plant-rich foods, that give my patients a variety of ways to enjoy this wonderful fruit.
Since blueberries contain flavonoids and other specific phytochemicals that help protect against vascular instability, I instruct my diabetes and heart disease patients to eat fresh blueberries every day, and to eat frozen blueberries in the wintertime. In my book, The End of Heart Disease, I cite a study that showed a 68 percent increase in blood nitric oxide levels among women who consumed blueberry powder daily for 8 weeks.[1] This is beneficial because nitric oxide relaxes and protects blood vessels.
