Immune System Booster Foods – Want a Cook

Immune system booster foods. The immune system is made up of organs, cells, and chemicals that work together to combat illness (microbes). White blood cells, antibodies, the complement system, the lymphatic system, the spleen, the thymus, and bone marrow are the primary components of the immune system.

Microbial infection and the immune system

Memory cells are kinds of white blood cells (B- and T-lymphocytes) that maintain a record of every pathogen that the immune system has ever vanquished. This implies that if the microbe re-enters the body, it can recognize and eliminate it immediately before it can proliferate and make you sick.

Because so many distinct viruses or strains of the same type of virus may cause various illnesses, some infections, such as the flu and the common cold, must be battled several times. Getting a cold or the flu from one virus does not provide protection to the others.

Immune system components

The following are the key components of the immune system:

  • White blood cells
  • Antibodies
  • The complement system
  • The lymphatic system
  • Spleen
  • Bone marrow
  • Thymus

White blood cells

They are generated in the bone marrow and are part of the lymphatic system. White blood cells circulate throughout your body, looking for foreign invaders (microbes) including bacteria, viruses, parasites, and fungi.


Antibodies aid the body in combating microorganisms and the toxins (poisons) they generate. They do this by recognizing antigens on the surface of the organism or in the chemicals they generate, which identify the microbe or toxin as alien. A huge variety of cells, proteins, and substances are involved in this assault.

System of complements

The complement system consists of proteins whose activities supplement the activity of antibodies.

The lymphatic system

It is a type of drainage system. The lymphatic system’s primary functions are as follows:

It maintains fluid levels in the body responds to germs deal with cancer cells deals with cell products that might otherwise cause sickness or problems, the gut absorbs part of the lipids in our food.

The lymphatic system is made up of the following components:

Lymph nodes (also known as lymph glands) capture microorganisms’ lymph vessels — tubes that transport lymph, the colorless fluid that bathes your body’s tissues and contains infection-fighting white blood cells (lymphocytes).

Marrow from the bones

The spongy substance located inside your bones is called bone marrow. It generates the red blood cells required by our body to transport oxygen, the white blood cells required to combat infection, and the platelets required to help our blood clot.


It generates T-lymphocytes, which are white blood cells.

Another defense of the body against microorganisms

In addition to the immune system, the body has numerous additional defense mechanisms against microorganisms, including:

Skin is a waterproof barrier that secretes oil that has antibacterial characteristics.

lungs Mucous (phlegm) in the lungs catches foreign particles, and tiny hairs (cilia) waft the mucous upwards, allowing it to be coughed out.

The mucous lining of the digestive tract includes antibodies, and the acid in the stomach can destroy most bacteria.

additional defense – bodily fluids such as skin oil, saliva, and tears contain anti-bacterial enzymes that aid in infection prevention. Constant flushing of the urinary system and bowel is also beneficial.

Fever is a type of immune system reaction

Some illnesses can cause an increase in body temperature, or fever. Some bacteria can be killed by a temperature increase. Fever also initiates the body’s healing process.

Immune system diseases that are common

Immune system overactivity can manifest itself in a variety of ways, including:

Allergy disorders are conditions in which the immune system overreacts to allergens. Allergies are quite prevalent. Allergies to foods, medicines, or stinging insects, anaphylaxis (life-threatening allergy), hay fever (allergic rhinitis), sinus illness, asthma, hives (urticarial), dermatitis, and eczema are examples of these conditions.

Autoimmune disorders are conditions in which the immune system attacks normal bodily components. Autoimmune disorders range in severity from common to rare. Multiple sclerosis, autoimmune thyroid disease, type 1 diabetes, systemic lupus erythematosus, rheumatoid arthritis, and systemic vasculitis are a few examples.

Immune system inactivity, often known as immunodeficiency, can cause:

  • Primary immunodeficiency disorders such as common variable immunodeficiency (CVID), x-linked severe combined immunodeficiency (SCID), and complement deficits are instances of hereditary conditions.
  • develop as a result of medical treatment – this might be owing to medicines like corticosteroids or chemotherapy, or it can be caused by another disease like HIV/AIDS or some forms of cancer.

When the immune system is underactive, it may not operate properly, leaving people exposed to diseases. It is potentially fatal in extreme situations.

Immunosuppression therapy is required for those who have undergone an organ transplant to prevent the body from fighting the donated organ.

Immunoglobulin treatment

It is a kind of immunoglobulin therapy. Immunoglobulins (also known as antibodies) are used to treat patients who cannot produce enough antibodies on their own or whose antibodies do not function correctly. Immunoglobulin therapy is the name given to this treatment.

Until recently, immunoglobulin therapy in Australia mostly required the administration of immunoglobulins via a drip into a vein, a procedure known as intravenous immunoglobulin (IVIg) therapy. Subcutaneous immunoglobulin (SCIg) may now be administered into the fatty tissue beneath the skin, perhaps benefiting certain patients. This is referred to as SCIg treatment (subcutaneous infusion).

Subcutaneous immunoglobulin is a kind of immunoglobulin that is comparable to intravenous immunoglobulin. It is generated from plasma, which is the liquid component of blood that contains essential proteins such as antibodies.

SCIg treatment is currently available in many healthcare settings for qualified individuals with certain immunological disorders. If you are interested, please consult with your treating expert about your specific needs.


Immunization mimics the body’s natural immunological response. In the body is administered a vaccine (a little quantity of a carefully treated virus, bacteria, or toxin). The body then produces antibodies against it. If a vaccinated person is exposed to a genuine virus, bacterium, or toxin, they will not become unwell since their body will identify it and know how to resist it successfully.

Many illnesses, including measles and tetanus, have vaccines available. Your health, age, lifestyle, and employment all influence the immunizations you may require. These components are referred to together as HALO, which is defined as:


health some medical problems or circumstances may make you more susceptible to vaccine-preventable illnesses. Premature delivery, asthma, diabetes, heart, lung, spleen, or kidney disease, down syndrome, and HIV, for example, may necessitate extra or more frequent immunizations.


Age – various ages necessitate different vaccine-preventable illnesses protection. The National Immunization Program of Australia recommends immunizations for newborns, children, the elderly, and those at risks, such as Aboriginal and Torres Strait Islander people. The majority of recommended vaccinations are free for these populations.


Lifestyle– decisions might have an influence on your immunization requirements. Traveling to certain countries, planning a family, sexual activity, smoking, and participating in contact sports that may expose you directly to someone else’s blood may necessitate extra or more frequent immunizations.


employment – If you work in an activity that exposes you to vaccine-preventable diseases or puts you in touch with individuals who are more susceptible to difficulties from vaccine-preventable diseases, you are more likely to require more immunizations or require them more frequently (such as babies or young children, pregnant women, the elderly, and people with chronic or acute health conditions). ­ Discuss your immunization needs with your doctor if you work in elderly care, childcare, healthcare, emergency services, or sewage repair and maintenance, for example. Some businesses pay for appropriate vaccines for their workers.

Immune System Boosting Foods

Immune system enhancers

If you want to know how to avoid colds, flu, and other ailments, the first place to go is the grocery store.

An essential point to remember, there is no substance that will cure or prevent illness.

With the 2019 coronavirus COVID-19 pandemic, it’s extremely vital to realize that no supplement, diet, or another lifestyle adjustment may protect you from COVID-19 other than physical distance, also known as social distancing, and good hygiene measures.

Currently, no evidence supports the usage of any supplement to particularly protect against COVID-19.

Fruits with citrus peel

After catching a cold, most individuals go for vitamin C. This is due to the fact that it aids in the development of your immune system.

Vitamin C is considered to boost the formation of white blood cells, which are essential for combating infections.

Citrus fruits that are popular include:

Grapefruit, oranges, clementine’s, tangerines, lemons, limes

Because your body can neither generate nor retain vitamin C, you must consume it on a regular basis to maintain your health. Most individuals should consume the following quantity on a daily basis:

Women should take 75 mg.

Men should take 90 mg.

If you choose supplements, don’t exceed 2,000 milligrams (mg) per day.

Also, while vitamin C may help you recover faster from a cold, there is no proof that it is helpful against the new coronavirus, SARS-CoV-2.

Bell peppers, red

Red bell peppers provide nearly three times the amount of vitamin C as a Florida orange

Vitamin C may help you maintain healthy skin in addition to strengthening your immune system.


This is supercharged with vitamins and minerals. Broccoli is one of the healthiest veggies you can eat since it is high in vitamins A, C, and E, as well as fiber and many other antioxidants.

The key to preserving its potency is to boil it as little as possible, if at all.


Garlic may be found in nearly every cuisine on the planet. It gives a little zing to food and is essential for good health.

Its significance in combating illnesses was recognized by early cultures. Garlic may also delay artery hardening, and there is some evidence that it may help lower blood pressure.

Garlic’s immune-boosting effects appear to be due to a high quantity of sulfur-containing compounds.


Another item that many people resort to when they are unwell is ginger. Ginger may help reduce inflammation, which can assist with a sore throat and other inflammatory diseases. Ginger may also assist with nausea.

While ginger is commonly used in sweet sweets, it also contains some heat in the form of gingerol, a cousin of capsaicin.

Ginger may also help with chronic pain and may have cholesterol-lowering properties.


Spinach made our list not just because it is strong in vitamin C, but also because it includes a lot of antioxidants and beta carotene, which may aid our immune systems fight illnesses.


These cultures may help your immune system fight illnesses by stimulating them.

Purchase plain yogurt rather than flavored and sugar-laden varieties. Instead, you may sweeten plain yogurt with fresh fruits and a sprinkle of honey.

Yogurt may also be a good source of vitamin D, so look for products that are fortified with this vitamin. Vitamin D is considered to strengthen our body’s natural defense against illnesses by helping to control the immune system.

Clinical studies are even being planned to investigate its potential impact on COVID-19.


Vitamin E often takes a second seat to vitamin C when it comes to preventing and treating colds. This powerful antioxidant, on the other hand, is required for a strong immune system.

It’s a fat-soluble vitamin, which means it needs fat to be absorbed effectively. Almonds, for example, are abundant in vitamin E and contain beneficial lipids.

Adults require just approximately 15 milligrams of vitamin E each day.

Sunflower kernels

Sunflower seeds are abundant in minerals including phosphorus and magnesium, as well as vitamins B-6 and E.

Vitamin E helps to regulate and maintain immune system activity.

Avocados and dark leafy greens are two more foods strong in vitamin E.

Sunflower seeds have high selenium content as well. Just 1 ounce contains approximately half of the selenium that the average adult needs on a daily basis. A number of researches, primarily on animals, have looked at its ability to resist viral diseases such as swine flu (H1N1).


Turmeric is a common component in many curries. For years, this bright yellow, bitter spice has been utilized as an anti-inflammatory in the treatment of osteoarthritis and rheumatoid arthritis.

High quantities of curcumin, which gives turmeric its characteristic color, have been shown in studies to help reduce exercise-induced muscle damage. Curcumin has shown potential as an immune booster (based on studies).

A cup of green tea

Flavonoids, a kind of antioxidant found in both green and black teas, are plentiful. Green tea especially shines when it comes to levels of epigallocatechin gallate (EGCG), another potent antioxidant.

EGCG has been proven in trials to improve immunological function. During the fermentation process, a substantial amount of the EGCG in black tea is destroyed. Green tea, on the other hand, is steamed rather than fermented, and therefore, As a result, the EGCG is maintained.

Green tea also contains a lot of the amino acid L-thiamine. L-thiamine may aid in the production of germ-fighting chemicals by your T cells.


Another fruit high in vitamin C is papaya. A single medium fruit provides more than double the daily value of vitamin C.

Papayas also contain papain, an anti-inflammatory digestive enzyme.

Papayas are high in potassium, magnesium, and folate, all of which are good for your general health.


Kiwis, like papayas, are naturally high in a variety of vital elements such as folate, potassium, vitamin K, and vitamin C.

Vitamin C helps white blood cells fight illness, while the other minerals in kiwi keep the rest of your body running smoothly.


The soup may help reduce inflammation, which may alleviate cold symptoms.

Nearly one-third of your daily required dose of B-6 is found in 3 ounces of light turkey or chicken meat.

Many of the chemical reactions that occur in the body are influenced by vitamin B-6.

Boiling chicken bones yield stock or broth rich in gelatin, chondroitin, and other minerals beneficial to gut healing and immunity.


Shellfish may not be the first thing that comes to mind for many people looking to strengthen their immune system, but some varieties of shellfish are high in zinc.

Zinc does not get as much attention as many other vitamins and minerals, yet it is necessary for our immune cells to function correctly.

Shellfish with a high zinc content include:

oysters, crab, lobster, mussels.

Remember that you don’t want to consume more than the daily suggested quantity. Zinc from a reliable source in your diet:

Adult males should take 11 mg.

8 mg for the majority of adult females

Excess zinc can actually impair immune system function.

More infection-prevention strategies
