Here are 15 powerful foods that can help boost your immune system:

1. Citrus Fruits: Packed with vitamin C, these vibrant fruits are a classic immune-boosting choice. Oranges, grapefruits, clementines, tangerines, lemons, and limes all offer a potent dose of this essential vitamin. Vitamin C helps promote the production of white blood cells, which are the body’s first line of defense against infections.

Red bell peppers are even richer in vitamin C than oranges, making them an excellent choice for supporting your immune system. They also contain a variety of other nutrients, including beta-carotene and vitamin E, which are known for their antioxidant properties.

3. Broccoli: This cruciferous vegetable is a powerhouse of nutrients, including vitamin C, vitamin A, and fiber. These nutrients work together to support immune function and help protect cells from damage. Broccoli is also a good source of sulforaphane, a compound with potential anti-inflammatory and antiviral properties.

4. Garlic: This pungent bulb has been used for centuries for its medicinal properties. Garlic contains allicin, a compound with potent antimicrobial and immune-boosting effects. Studies suggest that garlic may help reduce the severity and duration of colds and flu.

8. Almonds: These nuts are packed with vitamin E, an antioxidant that helps protect cells from damage. Almonds are also a good source of magnesium, zinc, and copper, which are all important for immune function.
