"Surprising Truths: Blueberries, Lightning Strikes, and Gut Health"

Research from the University of Bristol has revealed that blueberries aren't actually blue, but appear so due to a trick of the light caused by a colorless, two micron-thick wax layer covering the fruit, which has an intricate microscopic structure that interferes with light and makes it seem blue to the naked eye. The skin of the fruit is black and the berry juice is red, with no trace of any blue pigment in either the flesh or skin. This discovery has left many people surprised and intrigued, as the beloved superfood's true color is unveiled.
