Oranges are famous for the amount of vitamin C in them. Pirates would routinely bring them on their months-long voyages in order to keep the scurvy, a dangerous sickness brought on by a lack of fruits and vegetables, at bay. Well, strawberries would like a word with oranges, because strawberries actually contain more vitamin C than oranges! You only need approximately 5 strawberries per day to get nearly 100% of your daily vitamin C requirements. You need over 1 whole orange to get the same effect.
