Fruits and vegetables
There are many benefits to making fruits and vegetables a significant part of your dietary consumption. Both contain an abundant amount of antioxidants and can help to reduce oxidative stress2, a naturally-occurring imbalance of free radicals and antioxidants in your body that can lead to cell and tissue damage. Fruits and vegetables are also a healthy source of the essential vitamins and minerals needed for a strong immune system. For example, vitamin C, which is well recognised for its role in the human immune system3, can be found in citrus fruits, kiwis, peppers, broccoli, and spinach. Other fruits and vegetables, such as avocados, blackberries, green peas, and spinach are all good sources of zinc, a mineral which promotes the growth, maturation, and activity of immune cells4.
