Yoghurt
Yoghurts are great for the immune system because they contain the necessary vitamins and minerals to strengthen your body against infections. Greek yoghurt is one of the healthiest types of yoghurt because it has live and active cultures which improve the activity of the immune system. It is also important to note that yoghurts are rich in vitamin D which protects the teeth and bones. When picking yoghurts to incorporate into your diet, ensure you pick those that are unflavoured or plain as they are generally healthier than sweetened yoghurts.
