Almost every fruit and vegetables contain vitamin C. However, fruits like cranberries and melons have higher Vitamin C content than the others. Hot peppers also belongs to the richest source of this vitamin. However
since this vitamin is water soluble, its effectiveness is easily lost from its sources like vegetables if cooked and boiled for long time. So, steaming and quick stir frying of the vegetables is more recommended that long boiling or overcooking them to retain the vitamins and minerals inside the food.
