 Vitamin C plays an important role in keeping

 us healthy.Most mammals produce it in their

 livers, so they never suffer from a lack of it.

Curiously, however, some mammals, such as

humans and apes, cannot do so. What happens

when you lack this important vitamin? You might

see black-and-blue marks on your skin. Your 

teeth could suffer, too: the pink area around 

them might become soft and bleed easily. These

are just a couple of good reasons to eat plenty

of fresh fruit.
