Healthy foods to boost immunity
1. Citrus fruits
Citrus
fruits like oranges and grapefruits are excellent sources of vitamin C, which
is known for boosting immunity and reducing the duration of cold and cough
symptoms. Vitamin C boosts the generation of white blood cells, crucial for
combating infections. Many people turn to vitamin C when they catch a cold

choose from, it's easy to add a squeeze of this vitamin to any meal. Popular
citrus fruits include:
- Grapefruit
- Oranges
- Clementines
- Tangerines
- Lemons
- Limes
2. Red bell peppers
Red bell peppers are a powerhouse of vitamin C, containing nearly three times as much vitamin C (127 mg) per ounce as a Florida orange (45 mg). In addition to boosting your immunity, vitamin C contributes to healthy skin. Red bell peppers are also rich in beta-carotene, which your body converts into vitamin A, supporting the health of your eyes and skin.
3. Broccoli
Broccoli is a nutritional powerhouse, loaded with vitamins, minerals, fiber, and antioxidants. Steaming or microwaving it preserves its nutrients best. Research suggests it's great for preventing colds due to sulforaphane, which boosts immunity by activating antioxidant genes and enzymes in immune cells, combating free radicals.
4. Garlic
Garlic,
known for its flavor, has also been valued for centuries for its medicinal
properties. It fights infections, may help prevent artery hardening, and is
used for treating high blood pressure. Its immune-boosting abilities come from
sulfur compounds like allicin, which enhances the body's defense against colds
and flu, while also acting as an antibacterial and antiviral agent.
5. Ginger
Ginger,
famed for its ability to reduce inflammation, is a go-to remedy for sickness,
especially soothing sore throats and nausea. Its gingerol compound, akin to
capsaicin, provides its heat. Ginger may also alleviate chronic pain, lower
cholesterol, and boost the immunity, thanks to its anti-inflammatory and
antioxidant properties.
6. Spinach
7. Almonds
Almonds
are an excellent source of vitamin E, a powerful antioxidant that is crucial
for maintaining a healthy immunity. Unlike vitamin C, vitamin E is fat-soluble,
meaning it needs fat to be absorbed properly. Nuts, such as almonds, are not
only rich in vitamin E but also contain healthy fats. Adults require about 15
mg of vitamin E daily, and a half-cup serving of almonds, approximately 46
whole, shelled almonds, provides around 100% of the recommended daily amount.
8. Sunflower seeds
Sunflower
seeds are packed with essential nutrients like phosphorus, magnesium, and
vitamins B6 and E. Vitamin E plays a crucial role in regulating and maintaining
immunity function. Other foods rich in vitamin E include avocados and dark
leafy greens. Additionally, sunflower seeds are a great source of selenium,
with just 1 ounce containing nearly half of the selenium needed daily for the
average adult. While most studies on selenium's potential to combat viral
infections like swine flu (H1N1) have been conducted on animals, it still holds
promise as an immunity-boosting nutrient.
9. Turmeric
Turmeric,
a vibrant spice in curry dishes, is renowned for its anti-inflammatory
properties, aiding conditions like arthritis. Curcumin, its active compound,
reduces muscle damage post-exercise and shows potential as an immune booster
and antimicrobial agent, though more research is needed. Turmeric's curcumin
offers potent anti-inflammatory and antioxidant effects, promoting immunity and
overall health.
10. Green tea
Green
and black teas are rich in flavonoids, antioxidants beneficial for health.
Green tea contains high levels of EGCG, a potent antioxidant with potential
antiviral properties, supporting the immunity. Black tea's fermentation process
reduces EGCG, while green tea retains it. Both teas boost immunity and possess
anti-inflammatory properties due to flavonoids. Catechin, found in green tea,
acts as a strong antibacterial and antiviral agent against cold and flu
viruses.
11. Kiwi

Kiwi
is a nutrient powerhouse, boasting folate, potassium, vitamin K, and twice the
vitamin C of oranges. Its antioxidants, like lutein and zeaxanthin, make it
highly nutritious. Kiwis support immunity with compounds like vitamin C, fiber,
carotenes, and polyphenols, making them a valuable dietary addition.
12. Shellfish
While
shellfish might not be the first choice for those seeking to boost immunity,
certain types do provide zinc, a nutrient crucial for immunity. Varieties such
as oysters, crab, lobster, and mussels are particularly rich in zinc. It's
important to note the recommended daily intake of zinc to avoid
overconsumption, which can actually hinder immunity:
- 11 mg for adult men
- 8 mg for most adult women
Excessive
zinc intake should be avoided as it can have adverse effects on immunity.
13. Mushrooms
Button
mushrooms are rich in selenium and vitamin B complex, both of which contribute
to boosting immunity. Incorporating a mushroom omelet packed with vegetables
into your diet can be an excellent way to enhance your immunity.
14. Brown rice
Brown
rice is rich in magnesium, which plays a crucial role in promoting a healthy
nervous system.
15. Greek yogurt
Greek
yogurt is rich in probiotics and boasts higher protein content compared to
regular yogurt. A meta-analysis published in a scientific journal found that
individuals who consumed probiotics daily had a reduced risk of catching a cold
compared to those who did not consume probiotic-rich foods.
16. Blood oranges
17. Pomegranates

Pomegranates
are rich in polyphenols, which have been shown to aid in the treatment and
prevention of coughs and colds. Research indicates that concentrated levels of
polyphenol antioxidants, such as those present in pomegranate juice, can reduce
the duration of a cold by up to 40 percent.
18. Oregano
Oregano
is an herb renowned for its antimicrobial and immunity boosting properties,
making it a valuable addition to your culinary repertoire. It’s essential oils
possess antimicrobial, antiviral, and antifungal properties, potentially aiding
in the treatment of bacterial infections.

supplements can be beneficial in filling nutritional gaps or providing
additional support. Here are some of the best supplements known for their
immunity-boosting properties:
