Not if you brush your teeth right after eating them. Teeth are porous, so blueberries and other dark fruit contain pigments that can discolor teeth, just as they do fabric. Don’t have a toothbrush handy? A good rinse with water will also help, says Mark S. Wolff, a doctor of dental surgery and a professor at New York University School of Medicine.
Wolff, who researches which foods and drinks stain teeth, adds that it would be a mistake to skip berries just because they may stain your teeth. Berries are a healthy snack, and one of the best ways to boost antioxidants in your diet.
Blueberries, raspberries and especially the harder-to-find black raspberries are loaded with phytonutrients, including ellagic acid, which is linked to a healthier heart, digestive system, sharper eyes and better brain function, according to nutrition researchers at Oregon State University. Antioxidants have been linked to lowering your risk for such ailments as heart disease and cancer. And scientists at The University of Nottingham in England have shown that higher levels of antioxidants may reduce your risk for gum disease.
