Raspberries have a short season in America, but you can opt for frozen raspberries that are equally nutritious. Consuming a cup of raspberries (fresh) provides your body with 43% of Vitamin C DV, 41% of manganese DV and 32% of fiber DV. These in turn, help in regulation of blood sugar, improve calcium absorption, and contribute toward carbohydrate and fat metabolism. Raspberries also consist of minimum amounts of Vitamin E, folate, Vitamin K, magnesium, potassium, copper and biotin. Enjoy it in your smoothie, or a dessert (healthy of course).
