Blueberries

Blueberries rank first for the highest antioxidant capacity of any common fruit, delivering 9,019 ORAC units per 100g—over 50% more than #2 salmon, which offers no similar phytonutrients. At just 84 calories per cup, they provide anthocyanins linked in peer-reviewed studies to improved memory, reduced oxidative stress, and a 32% lower risk of cognitive decline in older adults, making them the superior choice for brain health compared to the typical fruit.
