Raspberries
Just 1 cup contains nearly half your daily manganese—important for brain and nerve function, as well as bone and joint health. Raspberries are high in fiber, vitamin C, and antioxidants, and low in carbohydrates. And the phytonutrients found in raspberries may help slow or reduce the growth of cancer cells, newer research suggests. If you can, buy organic raspberries; USDA research shows the fruit is one of the most commonly contaminated with pesticides.
