<human>:  Why is vitamin C important to our health and how can I incorporate it into my diet?
<bot>: Vitamin C is an essential nutrient that helps keep our immune system in tip-top shape. It can help protect our bodies from illnesses and diseases, and helps us heal faster. Additionally, Vitamin C helps with the absorption of iron and helps form collagen, a protein found in our skin, blood vessels, and bones. To incorporate Vitamin C into our diet, choose fresh fruits and vegetables such as oranges, grapefruit, bell peppers, broccoli, and kale as they are all excellent sources. We can also get Vitamin C from supplements and fortified foods like fortified cereals and juices.
