Boosted immune response -

It is unknown what is the best mix of cells or optimum number for the immune system to work at its best. For many people, the immune system works well to regulate itself and does not need any help.

However, in some people, medications or immune system disorders cause overactivity or low activity of the immune system. Disorders of the immune system are treated with specific medications that tackle the symptoms and associated infections. The primary components of the immune system include the lymph nodes, tonsils, spleen, bone marrow , and thymus.

There remains much to learn about the interconnectedness and intricacies of the immune response, however. To function well, the whole system requires harmony and balance. The immune system is not a single entity or force field that needs patching up to work properly.

No direct links have been identified between lifestyle and enhanced immune response, but researchers have investigated the effect of factors, such as exercise, diet, and stress on the response of the immune system.

The best thing you can do to maintain your immune system is to adopt healthy living strategies that will benefit the entire body, including your immune system. These strategies might include:. Consuming a balanced diet and eating the recommended amounts of nutrients will help maintain normal immune function.

Vitamins A, C, and D, and minerals — including zinc — play a role in the functioning of the immune system. If you eat a balanced diet, you will have no need to take supplements of these vitamins and minerals and taking extra will not particularly help your immune system.

Populations that are malnourished are known to be more susceptible to infection, and there is some evidence that deficiencies in certain micronutrients alter immune responses. For example, zinc deficiency — which may contribute to chronic diseases — has been demonstrated to negatively impact how the immune system responds to inflammation in older adults.

Vitamin D supplementation has been linked with alterations in the behavior of the immune system. Taking vitamin D supplements during pregnancy — a period where the immune system is in continual flux — may modify the immune system of the newborn in such a way that protects against respiratory infections and asthma.

Research suggests that vitamin D activates T cells that can identify and attack cancer cells and protect against colorectal cancer in some people. In older adults, vitamin D has also been shown to reduce respiratory infections.

Soluble fiber switches immune cells from pro-inflammatory to anti-inflammatory, which helps us to heal faster from infection. Pterostilbene and resveratrol, found in blueberries and red grapes, respectively, help raise the expression of the human cathelicidin antimicrobial peptide CAMP gene, which is involved in immune function.

The CAMP gene plays a vital role in the innate immune system. Probiotics may help counteract the adverse effects of broad-spectrum antibiotics by keeping the immune system ready to respond to new infections.

Fish oil rich in DHA has been found to enhance B cell activity, which could be promising for those with compromised immune systems. Prolonged fasting has been linked with stem cell regeneration of older and damaged immune cells.

High fat and high-calorie diets trigger a response from the immune system similar to a bacterial infection. Just like eating a healthy diet, regular physical activity contributes to overall good health and, therefore, a healthy immune system. Exercise promotes efficient blood circulation, which keeps the cells of the immune system moving so that they can effectively do their job.

One study revealed that just 20 minutes of moderate exercise stimulated the immune system, which, in turn, produced an anti-inflammatory cellular response.

The investigators noted that their finding has encouraging implications for people with chronic diseases — including arthritis and fibromyalgia — and obesity.

Other research discovered that the best way to avoid adverse immune system changes and help the body to recover after intense exercise was to consume carbohydrates during or after. The authors of the paper suggest that between 30 and 60 grams of carbs every hour during physical activity can help maintain normal immune function.

In addition to a balanced diet and regular exercise, scientists have found evidence of other factors that may affect the response of the immune system. Getting outside in the sunlight may benefit the immune system.

Researchers discovered that sunlight energizes infection-fighting T cells that play a key part in immunity. A study uncovered that anticipating a happy or funny event increased levels of endorphins and other hormones that induce a state of relaxation.

Our immune system then adapts by remembering the foreign substance so that if it enters again, these antibodies and cells are even more efficient and quick to destroy it.

Antigens are substances that the body labels as foreign and harmful, which triggers immune cell activity. Allergens are one type of antigen and include grass pollen, dust, food components, or pet hair. Antigens can cause a hyper-reactive response in which too many white cells are released.

For example, an allergy to mold triggers symptoms of wheezing and coughing in a sensitive individual but does not trigger a reaction in other people. When pathogens attack healthy cells and tissue, a type of immune cell called mast cells counterattack and release proteins called histamines, which cause inflammation.

Inflammation may generate pain, swelling, and a release of fluids to help flush out the pathogens. The histamines also send signals to discharge even more white blood cells to fight pathogens.

However, prolonged inflammation can lead to tissue damage and may overwhelm the immune system. Autoimmune disorders like lupus, rheumatoid arthritis, or type 1 diabetes are partly hereditary and cause hypersensitivity in which immune cells attack and destroy healthy cells.

Immunodeficiency disorders can depress or completely disable the immune system, and may be genetic or acquired. Acquired forms are more common and include AIDS and cancers like leukemia and multiple myeloma. Eating enough nutrients as part of a varied diet is required for the health and function of all cells, including immune cells.

Certain dietary patterns may better prepare the body for microbial attacks and excess inflammation, but it is unlikely that individual foods offer special protection. Examples of nutrients that have been identified as critical for the growth and function of immune cells include vitamin C, vitamin D, zinc, selenium, iron, and protein including the amino acid glutamine.

Diets that are limited in variety and lower in nutrients, such as consisting primarily of ultra-processed foods and lacking in minimally processed foods, can negatively affect a healthy immune system. It is also believed that a Western diet high in refined sugar and red meat and low in fruits and vegetables can promote disturbances in healthy intestinal microorganisms, resulting in chronic inflammation of the gut, and associated suppressed immunity.

The microbiome is an internal metropolis of trillions of microorganisms or microbes that live in our bodies, mostly in the intestines.

It is an area of intense and active research, as scientists are finding that the microbiome plays a key role in immune function. The gut is a major site of immune activity and the production of antimicrobial proteins.

A high-fiber plant-rich diet with plenty of fruits, vegetables, whole grains, and legumes appear to support the growth and maintenance of beneficial microbes.

Certain helpful microbes break down fibers into short chain fatty acids, which have been shown to stimulate immune cell activity. These fibers are sometimes called prebiotics because they feed microbes. Therefore, a diet containing probiotic and prebiotic foods may be beneficial.

Probiotic foods contain live helpful bacteria, and prebiotic foods contain fiber and oligosaccharides that feed and maintain healthy colonies of those bacteria.

Animal studies have found that deficiencies in zinc , selenium , iron , copper, folic acid , and vitamins A , B6 , C , D , and E can alter immune responses. Epidemiological studies find that those who are poorly nourished are at greater risk of bacterial, viral, and other infections.

Eating a good quality diet, as depicted by the Healthy Eating Plate, can prevent deficiencies in these nutrients. However, there are certain populations and situations in which one cannot always eat a variety of nutritious foods, or who have increased nutrient needs. In these cases a vitamin and mineral supplement may help to fill nutritional gaps.

Studies have shown that vitamin supplementation can improve immune responses in these groups. The elderly are a particularly high-risk group. The immune response generally declines with increasing age as the number and quality of immune cells decreases.

This causes a higher risk of poorer outcomes if the elderly develop chronic or acute diseases. In addition, about one-third of elderly in industrialized countries have nutrient deficiencies.

Diet variety may also be limited due to budget constraints or lower interest in cooking for one person; poor dentition; mental impairment; or lack of transportation and community resources to obtain healthy food.

Megadose supplements many times the RDA do not appear justified, and can sometimes be harmful or even suppress the immune system e. Remember that vitamin supplements should not be considered a substitute for a good diet because no supplements contain all the benefits of healthful foods.
