7 Nutrient-Dense Foods to Boost Your Immune System Naturally
A strong immune system is your body’s primary defense against illness.
Focusing on whole, nutrient-dense foods is the most sustainable way to support your long-term health. Here are seven evidence-based foods to add to your grocery list.
1. Citrus Fruits (Vitamin C)
Most people turn to citrus when they feel a cold coming on. This is because Vitamin C is thought to increase the production of white blood cells, which are key to fighting infections. Common choices include oranges, grapefruits, lemons, and limes.
2. Red Bell Peppers (Vitamin Powerhouse)
Gram for gram, red bell peppers contain almost three times as much Vitamin C as a Florida orange. They are also a rich source of beta-carotene, which keeps your eyes and skin healthy.
3. Broccoli (Vitamin and Mineral Rich)
Broccoli is supercharged with vitamins A, C, and E, as well as many other antioxidants and fiber. It is one of the healthiest vegetables you can put on your plate. To keep its power intact, cook it as little as possible.
4. Garlic (The Natural Fighter)
Garlic is found in almost every cuisine in the world. It adds a little zing to food and is essential for your health. Its immune-boosting properties seem to come from a heavy concentration of sulfur-containing compounds, such as allicin.
5. Ginger (Inflammation Reducer)
Ginger is another ingredient many turn to after getting sick. Ginger may help decrease inflammation, which can help reduce a sore throat and other inflammatory illnesses.
6. Spinach (Antioxidant Support)
Spinach made it onto our list not just because it’s rich in vitamin C, but also because it is packed with numerous antioxidants and beta-carotene, which may increase the infection-fighting ability of our immune systems.
7. Yogurt (Probiotic Health)
Look for yogurts that have "live and active cultures" printed on the label, like Greek yogurt. These cultures can stimulate your immune system to help fight diseases. Yogurt is also a great source of Vitamin D, which helps regulate the immune system.
