10 Immunity-Boosting Foods to Add to Your Daily Diet
(I have handpicked ten foods to include in your everyday diet that will boost your immunity)
First lockdown, then viral season—now every family’s shop-to-kitchen journey echoes with one question: “How to boost immunity?” In this blog post, we present ten science-backed, flavourful and easily available foods that will naturally turbo-charge your immunity.
1. Citrus Fruits
Example: Orange, Lemon, Grapefruit
Citrus fruits have been grandmothers’ first line of defense for centuries as 100 g of orange contains about 53 mg of vitamin C—this vitamin helps in making white blood cells (WBCs) and is also an antioxidant. A glass of lemon water every morning or an orange as a snack covers up to 90% of your Daily Value (DV).
Quick Tip:
Add a whole kiwi + orange slices to breakfast oats; it’s a double vitamin C rich food strike.
2. Red Bell Pepper (Red Bell Pepper):
Red bell peppers contain up to 128 mg/100 g of vitamin C—~2.5 times more than oranges. It also contains beta-carotene which is converted to vitamin A in the body to protect mucous membranes and skin. Add raw cubes to salads or stir-fry, just don’t overcook to preserve nutrients.
3. Kiwifruit (SunGold Kiwi):
One golden kiwi (161 mg vit C/100 g) gives you twice your daily vitamin C needs. Also packed with potassium, folate and fiber.
4. Broccoli:
This cruciferous vegetable provides vitamin C (89 mg/100 g) as well as vitamin K, folate and phytochemicals. Gentle steaming prevents the enzyme myrosinase from activating the immune-related sulforaphane.
5. Garlic:
When crushed, garlic’s alliin forms allicin, which is the basis of 80% of the bioactive compounds. Allicin has increased WBC activity and decreased the duration of viral infection-related symptoms in in vitro and animal studies. Eat 1-2 cloves of raw garlic in the morning on an empty stomach or include it in dal-tadka.
6. Ginger:
Compounds like 6-Gingerol and 6-Shogaol reduce inflammation by suppressing the NF-κB pathway and decrease cytokines like IL-6, TNF-α. Ginger-turmeric tea or kadha is a great “immunity-shot” during seasonal changes.
7. Turmeric:
Curcumin has powerful anti-inflammatory and immunomodulatory properties—it balances the function of T-cells, B-cells, macrophages. “Turmeric milk” with a pinch of black pepper in warm milk increases the absorption of curcumin manifold.
8. Probiotic Yogurt:
Live Lactobacillus and Bifidobacterium in all types of yogurt work at two levels of the immune system—strengthening the gut barrier and increasing the activity of NK-cells/γδ T-cells. In a recent RCT, probiotic yogurt improved insulin-resistance and inflammatory markers.
DIY:
Add ½ cup probiotic yogurt, 1 kiwi, and 10 almonds to your morning smoothie bowl—three superfoods in one!
9. Almonds:
Just 23 dry-roasted almonds provide 7 mg of vitamin E—a lipid-membrane antioxidant that protects immune cells from oxidative damage. In one study, 56 g/day of almonds increased α-tocopherol by 8% and lowered LDL.
| Snack | Serving | Key Nutrient | % DV (approx.) |
|---|---|---|---|
| Almonds | 23 nuts (28 g) | Vitamin E | 48% |
| Sunflower Seeds | 2 Tbsp | Vitamin E | 37% |
10. Spinach:
Spinach is an excellent source of vitamin A (green carotene), vitamin C and the phytonutrient lutein. It supports WBC production and protects the mucus-lining. Try Palak-Chana or Palak-Corn Bhurji 3-4 times a week.
