During cold and flu season, staying healthy is of utmost importance. Fox News medical contributor Dr. Nicole Saphier offers some remarkable power foods that can significantly boost the immune system. Let's explore these immune boosters together.

Discover the Foods that Fortify Your Immune System

Red Bell Pepper: A Vitamin C Powerhouse

One raw red bell pepper contains double the daily dose of vitamin C. As Dr. Saphier pointed out, vitamin C is truly excellent for our immune system. Whether grilled or boiled, it still retains its nutritional value and other beneficial nutrients. She even slices red bell peppers and serves them to her kids almost every morning before school, emphasizing its easy incorporation into our daily diet.

Blueberries: Nature's Antioxidant Powerhouse

Saphier described blueberries as a "superfood" and "nature's powerhouse." With one of the highest amounts of jam-packed, antioxidant, low-calorie, and low-sugar content among fruits and veggies, they are a great addition to our diet. Just grabbing a handful of blueberries is a simple yet effective way to nourish our bodies.

Citrus: The Vitamin-Rich Delight

Oranges and lemons, as citrus fruits, provide a high amount of vitamins. However, it's important to note that citrus does have higher sugar content. For diabetic individuals, it's crucial to be cautious about the amounts. The best way to enjoy citrus is by eating it raw or adding it to a vitamin-packed juice. Dr. Saphier likes to make a green version with spinach, celery, turmeric, ginger, lemon, and other ingredients, which is filled with vitamins.

Garlic: A Natural Immune Defender

Surprisingly, garlic is one of the best things for our immune system. Dr. Saphier takes liquid garlic and combines it with other ingredients like turmeric and ginger in a juice to give an extra immune boost. She emphasized that having a healthy body going into cold and flu season is the best bet for staying healthy.

Walnuts: Brain and Immune Health Booster

While not specifically called out for immune support, walnuts offer great benefits for both brain and cognitive health. As Dr. Saphier mentioned, they look like a "mini brain." She keeps walnuts in her office at the hospital as they are really good for us. It's advisable to choose organic options to avoid exposure to pesticides, hormones, and other additives, although they may be a bit more expensive. We hope that one day the prices will come down and make them more affordable and accessible.For more Health articles, visit foxnews.com/health.
