Peppers originated in the Americas. Columbus brought them back to Europe, and from there they spread to Africa and Asia.
Sweet peppers are low in calories, and supply folic acid, potassium and fibre. They are an excellent source of beta carotene and bioflavanoids. These substances are antioxidants which protect the body against arthritis, cancer and heart disease.
Most importantly, peppers are packed with wonderful vitamin C. The green ones have the smallest amount, and the red ones the most., but even the green peppers give you more vitamin C than an orange. This is more than your daily requirement. Keeping them in the fridge ensures no loss of this important vitamin whilst storing. Always source organic, if you can.
