The combination of protein-packed Greek yogurt and antioxidant-rich berries provides a powerful boost to brain function. Greek yogurt delivers sustained energy and concentration thanks to its high protein content, which is typically double that of regular yogurt, helping to prevent the mental fog that can come from hunger.
Berries, such as blueberries and strawberries, are loaded with flavonoids and antioxidants, which have been shown to enhance memory and improve cognitive performance.
