The Immune System Basics

How to improve your immune system with vitamins amid COVID-19 pandemic

The main purpose of your immune system is to protect your body from viruses and bacteria.

Without it, they would have free reign and you would be constantly falling ill.

Your immune system works by recognising the difference between your bodys cells and alien cells, allowing it to destroy any that could be potentially harmful.

This usually works well but can cause problems if your immune system wrongly classifies some of your own cells and attacks them instead.

The Importance Of Balance

Instead of concentrating on boosting the immune system, a more useful approach might be to think about balance, as a healthy immune system is one that sits in balance.

We can think about the immune system as a scale running from underactive to overactive. We know that an immune system that is not functioning properly is a bad thing for example it plays an important role in HIV and Malaria. But at the other extreme, an overactive immune system can start targeting our own cells.

In extreme cases, this causes autoimmune diseases like rheumatoid arthritis and multiple sclerosis. But an overly vigorous immune response can also cause inflammation which can be thought of as collateral damage, or friendly fire, from the war between the immune system and invading pathogens.

Serious illnesses and deaths caused by infections are often due to damage that comes from an over-vigorous immune response.

Support Your Immune Function With Good Nutrition

One of the most valuable things you have is your health. As a dietitian, I have received numerous queries about recommended foods, supplements and diet patterns to boost immune function. While it is true that nutrition plays a large role in immune function, diet recommendations for the prevention of acute illnesses, like COVID-19 and other viruses, don’t look a whole lot different than general guidelines for healthy eating.

I’ll start by saying that the concept of boosting the immune system through diet is flawed, as boosting refers to something that is stimulated above the normal level. A good diet cannot boost the immune system, but it’s important to maintain a functional immune system by avoiding immunodeficiency due to malnutrition or micronutrient deficiencies.

It’s important to note that no single food or nutrient will prevent illness. Also, the immune system is incredibly complex and influenced by a variety of other factors, including stress level, age, sleep and other medical conditions.

A few key micronutrients have been identified as critical for the growth and function of immune cells, including:

Need a multivitamin or mineral supplement?

A general multivitamin or mineral supplement providing no more than 100% of your recommended daily allowance can be used and is generally safe for many people. Your health care provider may recommend further supplementation based on your lab values or medical status.

Mom was right: Youre more likely to catch an infection if youespecially your extremitiesare cold. In one study, 90 people kept their feet in a bowl of cold water for 20 minutes and the same number put their feet in an empty container for a similar length of time. Five days later, 20 per cent of people with chilled feet had developed colds compared with 9 per cent of those whose feet stayed warm. Having cold extremities seems to reduce the supply of white blood cells, the immune systems first line of defense against invaders.

Vitamin D And Immune Health

Research shows that vitamin D plays an important role in immune function, and a deficiency in it is shown to increase your susceptibility to infection. “Some studies have shown that vitamin D deficiency is even associated with greater risk of self-reported upper respiratory tract infections,” Tolentino says. Further, “low serum levels of calcidiol are also associated with higher susceptibility to infections like tuberculosis, influenza, and viral infections of the upper respiratory tract,” Tolentino says.

One of the main functions of vitamin D is to help activate T cells, aka the “killer cells” in the body. T cells actually detect and destroy foreign pathogens — like viruses. “That makes vitamin D especially crucial for maintaining a functioning immune system that’s capable of fighting back foreign pathogens,” Tolentino says.

It’s important to know that although the coronavirus does affect the respiratory system, researchers and doctors know little about how vitamin D affects your risk of catching COVID-19 at this time. The best ways to reduce your risk of being infected with the coronavirus is to follow CDC and WHO guidelines, what your local officials say and to take care of your health as much as you can overall. Vitamin D is known to help the immune system, which is promising for protecting you from many different types of illness.

Exposing your skin to the sun is one way to get vitamin D.

Try Supplements To Boost Immune System Function

By combining immune system support supplements with lifestyle changes, you can help promote immunity. Although no supplement on its own is ever100 percent effective, the following supplements have shown promising results in scientific studies as supporters of multiple aspects of immune function:

  • Elderberry. Elderberries are natural sources of antioxidants. In addition, there is some evidence to suggest that elderberry may help the immune system fight off viruses and colds more quickly.
  • Vitamin C. This essential vitamin acts as an antioxidant and is required for immune function. One large study found that taking vitamin C helped to shorten the length of colds.
  • Zinc. The immune system uses this essential mineral to heal wounds and respond to threats. Studies have revealed that zinc supplements may help to reduce the length of colds.
  • Vitamin D. This essential vitamin acts more like a pro-hormone and, among its other well-known benefits, directly stimulates the function of immune cells. Plus, the sunshine vitamin tends to be more deficient in fall and winter, so its important to boost levels.
  • Yeast beta-glucans. These substances derived from yeast activate the immune system in the digestive tract. Since 70% or more of the immune system is located in the digestive tract, these molecules help increase immune vigilance and detection capabilities.

How Does Vitamin C Boost Your Immunity And Improve Your Health

Vitamin C is an essential nutrient that assists in the formation and maintenance of bones, blood vessels, and skin while strengthening your immunity. This nutrient is found naturally in several foods, especially in fruits and vegetables. Additionally, vitamin C supplements are also available.

As one could expect, COVID-19 has forced people to focus more on protecting themselves from illnesses and infections by strengthening their immunity. This article reviews the impact vitamin C has on your immunity and health.

Vitamin C An Essential Nutrient

Vitamin C or L-ascorbic acid is a water-soluble nutrient and antioxidant that can neutralize unstable compounds and help prevent or reverse cellular damage in our bodies. It is also involved in various biochemical processes related to immune health.

Major benefits of Vitamin C include:

The Impact of Vitamin C on Immunity

  • Selenium

Tip to remember: In a broader scope, having a well-rounded diet filled with fruits and vegetables is always a good route to take to strengthen your immune system.

Maintain A Healthy Diet

Will Vitamins Boost Immune System & Health, Science Based Answers to Know

As with most things in your body, a healthy diet is key to a strong immune system. This means making sure you eat plenty of vegetables, fruits, legumes, whole grains, lean protein and healthy fats.

In addition to providing your immune system the energy it needs, a healthy diet can help ensure you’re getting sufficient amounts of the micronutrients that play a role in maintaining your immune system, including:

  • Vitamin B6, found in chicken, salmon, tuna, bananas, green vegetables and potatoes
  • Vitamin C, found in citrus fruit, including oranges and strawberries, as well as tomatoes, broccoli and spinach
  • Vitamin E, found in almonds, sunflower and safflower oil, sunflower seeds, peanut butter and spinach

Since experts believe that your body absorbs vitamins more efficiently from dietary sources, rather than supplements, the best way to support your immune system is to eat a well-balanced diet.

Do Vitamins Play A Role In Immunity

The novel coronavirus is sweeping the world, and as a result, everyone is searching for ways to protect themselves and their loved ones. Many people have been buying supplements and vitamins, particularly so-called âimmune-boostingâ supplements, to try and stay healthy.â

Vitamins play a central role in helping our immune systems protect against infection and fight disease. Vitamins A, C, E, and B6 all support healthy, normal immune responses to pathogens like viruses, as do minerals like folic acid, zinc, selenium, iron, and copper.

Deficiencies of these nutrients can leave us more susceptible to infections or less able to shake off illness.

So, should we all be taking supplements to make sure weâre getting enough of these vital vitamins to keep our immune systems working properly? â

Itâs important to note that people with medically diagnosed vitamin deficiencies can benefit from appropriate supplements prescribed by a registered professional such as a physician or registered dietitian. â

For example, the CDC currently recommends vitamin D for breast-fed babies, and for children under 2 if they donât eat many vitamin D-rich foods.

As for most of the rest of the population? Unfortunately, vitamin supplements arenât the easy immunity solution that they might seem. â

How To Choose A Supplement

The FDA licenses various supplements. However, some of them are not held to the same safety standards as pharmaceuticals. Therefore, if you wish to take a vitamin C supplement, you should ensure that its a high-quality one bought from reliable sources. You should also have a clear idea about the dosage and choose supplements that have been tested by reputable companies. It is best to consult your doctor before you opt for a vitamin C or a multivitamin supplement.

To get enough of it in your diet, ensure you eat a variety of vegetables and fruits. Fruits rich in vitamin C include cantaloupe, orange, grapefruit, and other citrus fruits, kiwis, mangos, papayas, pineapples, strawberries, raspberries, blueberries, etc. Broccoli, Brussels sprouts, cauliflowers, certain peppers. spinach, tomatoes, and potatoes are some vegetables rich in vitamin C.

What Can You Do To Boost Your Immune System

The idea of boosting your immunity is enticing, but the ability to do so has proved elusive for several reasons. The immune system is precisely that a system, not a single entity. To function well, it requires balance and harmony. There is still much that researchers don’t know about the intricacies and interconnectedness of the immune response. For now, there are no scientifically proven direct links between lifestyle and enhanced immune function.

But that doesn’t mean the effects of lifestyle on the immune system aren’t intriguing and shouldn’t be studied. Researchers are exploring the effects of diet, exercise, age, psychological stress, and other factors on the immune response, both in animals and in humans. In the meantime, general healthy-living strategies make sense since they likely help immune function and they come with other proven health benefits.

How To Support The Immune System With Supplements

For the immune system to hit peak performance, it needs good, regular nourishment.

So, its understandable that eating a diet lacking in essential nutrients is connected with a higher risk of getting some health conditions.

If your diet isnt providing you with the micronutrients you need, supplements, such as multivitamins, offer additional support to your immune system.

Improve Immunity With Herbs And Supplements

Walk into a store, and you will find bottles of pills and herbal preparations that claim to “support immunity” or otherwise boost the health of your immune system. Although some preparations have been found to alter some components of immune function, thus far there is no evidence that they actually bolster immunity to the point where you are better protected against infection and disease. Demonstrating whether an herb or any substance, for that matter can enhance immunity is, as yet, a highly complicated matter. Scientists don’t know, for example, whether an herb that seems to raise the levels of antibodies in the blood is actually doing anything beneficial for overall immunity.
