Immune system benefits -

However, a balanced diet consisting of a range of vitamins and minerals, combined with healthy lifestyle factors like adequate sleep and exercise and low stress, most effectively primes the body to fight infection and disease. On a daily basis, we are constantly exposed to potentially harmful microbes of all sorts.

Our immune system, a network of intricate stages and pathways in the body, protects us against these harmful microbes as well as certain diseases. It recognizes foreign invaders like bacteria, viruses, and parasites and takes immediate action.

Humans possess two types of immunity: innate and adaptive. Innate immunity is a first-line defense from pathogens that try to enter our bodies, achieved through protective barriers.

These barriers include:. Adaptive or acquired immunity is a system that learns to recognize a pathogen. It is regulated by cells and organs in our body like the spleen, thymus, bone marrow, and lymph nodes.

When a foreign substance enters the body, these cells and organs create antibodies and lead to multiplication of immune cells including different types of white blood cells that are specific to that harmful substance and attack and destroy it. 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.

Several herbal supplements have been suggested to boost immune function. What does the research say? Diet Review: Anti-Inflammatory Diet.

How does the immune system work? The tasks of the immune system Without an immune system, we would have no way to fight harmful things that enter our body from the outside or harmful changes that occur inside our body. How is the immune system activated? Innate and adaptive immune system There are two subsystems within the immune system, known as the innate non-specific immune system and the adaptive specific immune system.

Your Immune system benefits system works Immune system benefits the clock to keep you healthy and to support recovery when illnesses strike, but it can't succeed on its own. The immune system requires key nutrients to build protective antibodies, proteins and enzymes to keep your immune system functioning. According to nutritional immunologiststhe best way to get these key nutrients is from immune-supporting foods as part of a balanced diet. But what nutrients does your immune system need most? As researchers seeks ways to systen health Quench thirst better older adults, they found that infections may give an unexpected boost to the immune system by mImune naïve Sgstem cells.

Janko Nikolich-Žugich, MD, PhD, is professor and chair of the Department of Immunobiology in the College of Medicine — Tucson. The immune system uses T cells, white blood cells that defend against pathogens such as viruses, bacteria and parasites, to fight infection. Nikolich-Žugich, who also is a member of the BIO5 Institute. Previously, it was thought infections primarily affected the creation of memory T cells. When exposed to a pathogen, some naïve T cells learn and remember, becoming memory T cells that prevent re-infection when they encounter the same pathogen again.
