### Why Purple? The Science Behind the Color
The captivating purple hue in many foods comes from a group of natural pigments called anthocyanins. These pigments are powerful antioxidants, meaning they help protect your cells from damage caused by free radicals. Free radicals contribute to aging and various diseases, making anthocyanin-rich foods a valuable addition to a healthy diet. The intensity of the purple color can vary depending on the pH level, temperature, and other factors, resulting in a spectrum of shades from deep violet to reddish-purple.
