Best Foods to Boost Immunity for Long-Haulers

Long COVID, sometimes referred to as “Long-Haul COVID,” has affected numerous individuals worldwide, with lingering symptoms persisting for months after the acute phase of the infection has subsided. For these “Long-Haulers,” supporting the immune system becomes paramount in their journey to recovery. Fortunately, nutrition can play a significant role in bolstering immunity. Here are some of the best foods that can enhance immune function, potentially aiding in the recovery of Long-Haulers.

1. Citrus Fruits

  • Why: They are packed with vitamin C, a known immune booster that encourages the production of white blood cells.
  • Examples: Oranges, grapefruits, lemons, limes, tangerines, and clementines.

2. Broccoli

  • Why: It’s loaded with vitamins C, A, and E, as well as fiber and other antioxidants.
  • Tip: To preserve its nutrient content, cook it as little as possible — steaming is the best option.

3. Red Bell Peppers

  • Why: Surprisingly, they contain twice as much vitamin C as citrus fruits. Additionally, they’re a rich source of beta carotene.
  • Benefits: Apart from boosting immunity, beta carotene helps maintain healthy skin and eyes.

4. Garlic

  • Why: Its immune-boosting properties come from a concentration of sulfur-containing compounds, such as allicin.
  • Tip: Add it to your daily meals for both flavor and health benefits.

5. Ginger

  • Why: Ginger can help reduce inflammation, which can aid in the immune response.
  • Tip: Add it to teas, dishes, or even consume it as a raw, fresh slice.

6. Spinach

  • Why: Rich in vitamin C, it also contains numerous antioxidants and beta carotene.
  • Tip: Like broccoli, it’s best when cooked as little as possible to retain its nutrients.

7. Yogurt

  • Why: It’s a probiotic source, meaning it can help improve gut health and, by extension, overall immunity.
  • Tip: Opt for plain yogurts without added sugars and consider those fortified with vitamin D.

8. Almonds

  • Why: They are packed with vitamin E, which is key to maintaining a healthy immune system, especially in the elderly.
  • Tip: A daily half-cup serving provides nearly 100% of the recommended daily amount of vitamin E.

9. Turmeric

  • Why: Known for its anti-inflammatory properties, curcumin, its active compound, has been shown to improve immune responses.
  • Tip: Incorporate it into curries, smoothies, or even warm milk.

10. Sunflower Seeds

  • Why: These seeds are packed with vitamins E and B-6, phosphorus, magnesium, and selenium.
  • Benefits: Selenium, in particular, is known to combat certain viruses.

11. Shellfish

  • Why: Some types are packed with zinc, which is essential for immune cell development and function.
  • Examples: Crab, clams, lobster, and mussels. (Note: Don’t consume too much zinc as it can inhibit immune function.)


A balanced diet with a diverse range of immune-boosting foods can be a foundational pillar in the recovery journey of Long-Haulers. However, it’s essential to remember that no single food will act as a panacea. It’s the synergy of various nutrients from different sources that bolsters our immune function. Always consult with a nutritionist or healthcare provider before making significant dietary changes, especially if dealing with lingering symptoms or other medical conditions.
