Fruits and vegetables
There are many benefits to making fruits and vegetables a significant part of your diet. Both are good sources of antioxidants and help reduce oxidative stress2, a natural occurrence in your body that is part of the aging process and leads to cell and tissue damage. Fruits and vegetables are also excellent sources of vitamins and minerals essential for a strong immune system. For example, vitamin C, well recognized for its role in the human immune system3, can be found in citrus fruits, kiwis, peppers, broccoli, and spinach. Other fruits and vegetables, like avocadoes, blackberries, green peas, and spinach are good sources of zinc, a mineral that promotes the growth, maturation, and activity of immune cells4.
