Cells, organs, tissues and proteins make up the immune system. All of these work together to keep the body free from pathogens, including bacteria, viruses, and other invaders that can cause disease.

When pathogens come into contact with the immune system, an immune response is triggered. Pathogens are killed by antibodies that bind to their antigens and are released by the immune system.

A person's immune system can be boosted by including certain foods in their diet. Read on to learn more about immune-boosting foods.

A nutritionally balanced diet is essential for good health. Here are some foods that can help your body fight disease:

1. Blueberries

The antioxidant properties of blueberries may improve immune system health.

A flavonoid called anthocyanin found in blueberries has antioxidant properties that may help boost the immune system of those who consume them. According to a study published in 2016, flavonoids play an important role in the immune defense mechanism of the respiratory tract.

Foods rich in flavonoids have been found to reduce the risk of colds compared to foods without flavonoids.

2. Dark Chocolate

Because dark chocolate contains theobromine, an antioxidant that protects body cells from free radicals, it may help boost the immune system.

The body releases free radicals when it breaks down food or comes into contact with pollutants. The cells of the body can be damaged by free radicals, leading to disease.

Despite its possible health benefits, dark chocolate is high in saturated fat and calories, so use it sparingly.

3. Turmeric

Many people use turmeric as a yellow spice in cooking. It can also be found in several complementary and alternative therapies. The immune system can benefit from consuming turmeric. The curcumin content of turmeric is responsible for this.

According to a 2017 review, curcumin has antioxidant and anti-inflammatory properties.

4. Fatty fish

Omega-3 fatty acids are found in oily fish such as salmon, anchovies, and tuna.

According to a study published in 2014, long-term consumption of omega-3 fatty acids may be less likely to develop rheumatoid arthritis.

Autoimmune diseases such as RA are caused by the immune system attacking healthy tissues in the body.

5. Broccoli

Broccoli also contains vitamin C. Sulforaphane, a powerful antioxidant, is also present. These benefits make it an excellent choice for vegetables that maintain a healthy immune system.

6. Sweet Potatoes

Sweet potatoes contain a lot of beta-carotene. It's the antioxidant that gives them their orange color.

Vitamin A is found in beta-carotene. It improves skin health and even protects the skin from the harmful effects of ultraviolet (UV).

7. Spinach

Spinach contains several nutrients and antioxidants that may help improve the immune system, including:

● flavonoids

● Carotenoids

● Vitamin C

● Vitamin E

Additionally, research suggests that flavonoids may help prevent the common cold or flu in otherwise healthy adults.

8. Ginger

Ginger is not only used as tea, but also in various foods and desserts.

Research suggests that ginger has anti-inflammatory and antioxidant properties that may have health benefits. However, more research is needed to clarify whether it helps prevent disease.
