A
person's health is maintained by having a strong immune system. Nutrients that
support the immune system can be found in foods like berries, oily fish,
turmeric, kefir, and others.
Organs,
cells, tissues, and proteins all make up the immune system. Together, these
perform physiological functions that fend off pathogens, which are the viruses,
bacteria, and foreign objects that cause infection or disease.
Immune
responses are triggered when the immune system comes into contact with a
pathogen. When a pathogen's antigens are attached to an antibody produced by
the immune system, the pathogen is killed.
A
person's immune system may be strengthened by including particular foods in
their diet.
Learn
20 foods that strengthen the immune system as you read on.
Here are the 20
Best Foods that Boost the Immune system?
A
balanced, healthy diet is essential for maintaining good health. The immune
system may benefit from the foods listed below:
1.
Blueberries
Antioxidant qualities in blueberries could help the immune system.
A
type of flavonoid called anthocyanin is found in blueberries, and it has
antioxidant properties that can help strengthen one's immune system. According
to a 2016 study, flavonoids are crucial to the immune defense of the
respiratory tract. People who consumed foods high in flavonoids had a lower
risk of developing an upper respiratory tract infection, or common cold, than
those who did not.
2. Dark chocolate
By
shielding the body's cells from free radicals, theobromine, an antioxidant
found in dark chocolate, may help to strengthen the immune system. When the
body digests food or comes into contact with pollutants, it produces molecules
called free radicals. The cells in the body can be harmed by free radicals,
which can also worsen existing illnesses. Dark chocolate may have health
benefits, but it's also high in calories and saturated fat, so it's best to
consume it in moderation.
3. Turmeric
Many
people use the yellow spice turmeric in their cooking. Some complementary medicines also contain it. An individual's immune response may be
strengthened by consuming turmeric.
This
is a result of the properties of the turmeric compound curcumin. Curcumin has anti-inflammatory and
antioxidant properties, according to a 2017 review.
4. Oily fish
Omega-3 fatty acids can be found in abundance in salmon, tuna, pilchards, and other oily fish. Long-term omega-3 fatty acid consumption may lower the risk of rheumatoid arthritis (RA), according to a 2014 study. When the immune system mistakenly attacks a healthy part of the body, it can lead to RA, a chronic autoimmune disease.

Another
source of vitamin C is broccoli. Strong antioxidants like sulforaphane are also
present. In order to maintain the health of your immune system, it is a wise
choice to consume this vegetable frequently.

carotene, a class of antioxidant that gives potatoes their orange color, is
abundant in sweet potatoes. Vitamin A can be found in beta carotene. It

rays' ability to cause skin damage.
7. Spinach
Due
to its abundance of vital nutrients and antioxidants, including, spinach may
strengthen the immune system.
•
Flavonoids.
•
Carotenoids.
•
Vitamin C.

Vitamin E.
The
immune system may benefit from vitamin C and E support. demonstrates that flavonoids
may be useful in shielding healthy individuals against the common cold.
8.
Ginger
In addition to being used in teas, ginger is used in many different foods and desserts. Ginger has anti-inflammatory and antioxidant properties, so it probably has health benefits, claims a review. To confirm whether it can truly prevent illness, more research is required.
9.
Garlic
Garlic may aid in the prevention of colds. The prevention of colds
and other illnesses is frequently achieved at home using garlic. One study
examined whether taking allicin-containing garlic supplements decreased the
risk of contracting the common cold.
Compared
to the group taking the garlic supplements, the participants taking the placebo
group experienced more than twice as many colds overall. However, the
researchers came to the conclusion that further study is required to establish
whether or not garlic can aid in cold prevention.
10. Green Tea
People
can use green tea as a substitute for black tea or coffee since it has less
caffeine than those beverages. It can help to boost immunity if you drink it. Green
tea contains flavonoids, which, like those in blueberries, may lessen the likelihood
of getting a cold.
11. Kefir
The fermented beverage kefir contains live cultures of bacteria that are good for your health. Drinking kefir, according to preliminary research, may strengthen the immune system. Several studies have demonstrated that regularly consuming kefir can help with.
•
Eliminating bacteria.
•
Lowering inflammation.
•
Enhancing antioxidant function.
The
vast majority of the studies that back this up were conducted in labs or on
animals. To fully understand how kefir might shield people from disease, more
research must be done.
12. Sunflower seeds
Salads
or breakfast bowls can taste good with sunflower seeds added. A powerful
antioxidant, vitamin E, is abundant in them. Similar to other antioxidants,
vitamin E strengthens the immune system by scavenging free radicals, which can
harm cells.
13. Almonds
Almonds are a good source of vitamin E and they also have fiber, manganese, and magnesium. Almonds are a nutritious snack that may strengthen the immune system—just a small handful or a quarter cup.
14. Oranges or kiwifruit (kiwis)
Vitamin
C, the vitamin that many people reach for when they feel a cold coming on, is
abundant in oranges and kiwis. Vitamin C
may shorten the duration of common cold symptoms and enhance immune system
performance, though it is unclear exactly how it works to help.
15. Red bell pepper
Red
bell peppers are a fantastic alternative source of vitamin C for people trying
to avoid the sugar in fruit. According to a study on cooking techniques,
roasting and stir-frying red bell peppers preserve their nutritional value
better than steaming or boiling.
16.
Shellfish
For
many people looking to strengthen their immune system, shellfish might not be
the first thing that comes to mind, but some varieties of shellfish contain
zinc, an element that supports immune function.
The
following shellfish species have high zinc content.
Oysters
are one example.
• Crab
• Lobster
• Mussels
• Oysters
It's
important to keep in mind that you shouldn't consume more zinc than the daily
recommended amount in your diet.
• 11 mg for adult men
• 8 mg for most adult women

fact, an excessive amount of zinc can suppress immune system activity.
17.
Poultry
When
you reach for chicken soup when you're sick, it's not just the placebo effect
that makes you feel better. Inflammation may be reduced by the soup, which may
help with cold symptoms. Vitamin B6 is abundant in poultry, such as chicken and
turkey. Nearly a third of your daily recommended intake of B6 is found in about
3 ounces of lean turkey or chicken meat.
Numerous
chemical processes that occur in the body require the vitamin B6 as a key
component. The production of fresh, healthy red blood cells also depends on it.
Gelatin, chondroitin, and other nutrients that are beneficial for gut healing
and immunity can be found in stock or broth made from simmering chicken bones.
18.
Papaya
100
percent of the daily recommended amount of vitamin C is present in one small
papaya. In addition to their anti-inflammatory properties, papayas contain the
digestive enzyme papain. Potassium, magnesium, and folate are all present in
papayas in respectable amounts and are all good for your general health.
19.
Yogurt
On
the label of yogurts like Greek yogurt, look for the words "live and
active cultures." These cultures might boost your immune system and aid
in the prevention of disease.
Try
to choose plain yogurts rather than those that are flavored and packed with sugar.
Instead, you can sweeten plain yogurt on your own by adding some honey and
wholesome fruits.
Try
to choose brands of yogurt that are fortified with vitamin D as this vitamin
can also be a great source of this food. Our body's natural defenses against
disease are thought to be strengthened by vitamin D, which also aids in immune
system regulation.
Studies
on its potential effects on COVID-19 are even being conducted in clinical
trials.
According
to current research, vitamin D deficiency may increase a person's risk of
contracting COVID19 and the severity of the disease as it progresses.
Therefore,
according to experts, supplementation may offer protection to those who are
vitamin D deficient. There is no proof that vitamin D can treat a COVID19
infection, though.
