- Foods rich in vitamin C including citrus, red peppers, kiwi, broccoli, berries and tomatoes. Start the day with a grapefruit, add sliced peppers to a sandwich at lunch and enjoy a cup of berries for a snack.
- Herbs and spices such as garlic, ginger, oregano, rosemary, and thyme. These herbs and spices contain ingredients that help fight off viruses and harmful bacteria and give your immune system a boost. Try garlic hummus or raw ginger tea, or add oregano and rosemary to salads, roasted vegetables, and tuna salad to increase your intake of herbs and spices.
