There is a lot of talk about “superfoods” these days. By definition, a superfood is “a nutrient rich food considered to be especially beneficial for health and well-being”. Blueberries are almost always included in a list of top superfoods to be included in a healthy diet.

What Makes Blueberries ‘Super’

Much of the power of blueberries is associated with their dark blue color. This rich color is a result of flavonoids, natural compounds that protect the brain from inflammation and oxidation. 

With these high levels of flavonoids, it makes sense that blueberries have been shown to preserve memory function. Blueberries are also helpful in hydrating the skin as well as other cells in the body due to their high water content.

Recent studies have shown an impressive relationship between the nutritional benefits of blueberries and the development of negative health effects tied to obesity. The anti-inflammatory impact of blueberries may prevent the development of chronic high blood pressure and other obesity-associated metabolic disturbances.

Blueberries and Warfarin

Blueberries, as other foods rich in color, are a healthy source of vitamins including Vitamin K. While blueberries have more Vitamin K than some fruits, it is an amount that is considered moderate and appropriate to be included in diets for people taking Warfarin. As with any vitamin-rich food, consistency in intake is key. Enjoying a uniform portion of blueberries regularly is a tasty way to maintain a healthy consumption of a superfood. If adding blueberries to your diet is new for you, it is a good idea to discuss this with your healthcare provider so they can monitor the impact it may have on your INR.
