Make your life sweeter with peppers. Nearly all peppers start out green, ripening on the vine to become red, orange or yellow, depending on the variety. It picked early, peppers will stay green, losing out on some of the nutritional power of their more colourful cousins. A green pepper has more vitamin C than an orange and more than 100 percent of our recommended daily intake. Red and yellow peppers have twice as much vitamin C as that.
