The acids also assisted in boosting the immune system and guarding the body against infection.

However, the researchers noted that more studies need to be conducted in order to validate garlic’s true impact on the common cold.

12. Ginseng Tea

However, the researchers noted that more research needs to be conducted to support ginseng’s immunity-boosting claims fully.

Where green tea really excels is in its levels of epigallocatechin gallate, or EGCG, another powerful antioxidant. EGCG has been shown to enhance immune function, is known to be a powerful antibacterial and antiviral, and can kill off cold-starting bacteria and the influenza virus. In the fermentation process, black tea goes through destroys a lot of the EGCG. Green tea, on the other hand, is steamed and not fermented, so the EGCG is preserved.

The alphabetic list of A-Z immunity-boosting foods will remain incomplete if we won’t include nuts or dry fruits in it.

24. Red Bell Pepper

If you think citrus fruits have the most vitamin C of any fruit or vegetable, think again. Ounce for ounce, red bell peppers contain twice as much vitamin C as citrus. So, Red bell peppers are another vitamin C-rich source for fighting colds. Thus this beautiful veggie owns its place in this list of A-Z immunity-boosting foods. They’re also a rich source of beta carotene. In a review, it noted that consuming 200 milligrams of vitamin C every day cut the risk of getting a cold in half for “extremely active” people.

25. Rosemary

Rosemary isn’t just a tasty herb to add to baked goods—it’s also an amazing anti-inflammatory and is a rich source of antioxidants. A review based on food science noted that most herbs, such as rosemary, contain antioxidants that serve as anti-inflammatory properties in the body. This anti-inflammatory effect allows for better digestive and gut health, leading to a boost in your immune system to keep you healthy. So, try to add such amazing aromatic herbs in your food to boost up your immunity.

26. Shellfish

Immunity booster foods

Shellfish isn’t what jumps to mind for many who are trying to boost their immune system, but some types of shellfish are packed with zinc.

Varieties of shellfish that are high in zinc include:

  • Crab
  • Clams
  • Lobster
  • Mussels

But keep in mind that you don’t want to have more than the daily recommended amount of zinc in your diet. For adult men, it’s 11 milligrams (mg), and for women, it’s 8 mg. Too much zinc can actually inhibit immune system function.

27. Spinach

Spinach made our list of A-Z immunity-boosting food items not just because it’s rich in vitamin C. It’s also packed with numerous antioxidants and beta carotene. Thus, spinach is a major superfood that is great for your overall health. It’s numerous antioxidants and beta carotene may increase the infection-fighting ability of our immune systems. Similar to broccoli, spinach is healthiest when it’s cooked as little as possible so that it retains its nutrients. However, light cooking enhances its vitamin A and allows other nutrients to be released from oxalic acid.

28. Sunflower seeds

Sunflower seeds can make a tasty addition to salads or breakfast bowls. They are full of nutrients, including phosphorous, magnesium, and vitamin B-6. They’re also incredibly high in vitamin E, a powerful antioxidant.

Vitamin E is important in regulating and maintaining immune system function. It does this by fighting off free radicals, which can damage cells.

29. Turmeric

You may know turmeric as a key ingredient in many curries. But this bright yellow, bitter spice is more than just a delicious kick to your next dinnertime meal; it contains a powerful anti-inflammatory compound called curcumin. (This same compound is what lends turmeric it’s signature vibrant orange-yellow color.).

So, Consuming turmeric may improve a person’s immune response. This is due to the qualities of curcumin. According to a study published in the Journal of Clinical Immunology, curcumin activates the production of T-cells, which are the main cells fighting for your health in your immune system.

30. Tomatoes

Tomatoes are a great food to eat when you’re sick due to their high concentration of vitamin C. Just one medium tomato contains more than 16 milligrams of vitamin C, which is a proven fuel to your body’s immune system. In a study, it noted that vitamin C was shown to be a vital part of the strength of the body’s phagocytes and t-cells, two major components of the immune system. The researchers also noted that a deficiency in this nutrient can lead to a weaker immune system and lower resistance to certain pathogens that can lead to illness.

So, eat tomatoes as a salad or include them in your platter in the form of veggie or soup, it will always be very good for your health and immunity.

31. Water

In your sickness, good ol’ H2O can be one of the most helpful drinks to sip on. Staying hydrated can help loosen trapped mucus, according to The Mayo Clinic. Try drinking at least the recommended eight glasses of water a day to keep yourself fully hydrated, as we tend to lose more fluids when we’re sick, The Mayo Clinic suggests. So, water is our basic fluid, which occupies its important place in the list of A-Z immunity-boosting foods.

32. Yogurt

Look for yogurts that have “live and active cultures” printed on the label, like Greek yogurt. These cultures may stimulate your immune system to help fight diseases. Try to get plain yogurts rather than the kinds that are preflavored and loaded with sugar. You can sweeten plain yogurt yourself with healthy fruits and a drizzle of honey instead.

Yogurt can also be a great source of vitamin D, so try to select brands fortified with vitamin D. Vitamin D helps regulate the immune system and is thought to boost our body’s natural defenses against diseases.

So, friends, this is all the A-Z list of superfoods that boost up and keep our immunity on a good level to fight with cold, flu and some kind of infections. I hope, that you found it helpful.
