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.

What Is Our Immune System? These barriers include: Skin that keeps out the majority of pathogens Mucus that traps pathogens Stomach acid that destroys pathogens Enzymes in our sweat and tears that help create anti-bacterial compounds Immune system cells that attack all foreign cells entering the body Adaptive or acquired immunity is a system that learns to recognize a pathogen.

Other conditions that trigger an immune response Antigens are substances that the body labels as foreign and harmful, which triggers immune cell activity. What factors can depress our immune system? Older age: As we age, our internal organs may become less efficient; immune-related organs like the thymus or bone marrow produce less immune cells needed to fight off infections.

Aging is sometimes associated with micronutrient deficiencies, which may worsen a declining immune function. Environmental toxins smoke and other particles contributing to air pollution, excessive alcohol : These substances can impair or suppress the normal activity of immune cells.

Excess weight: Obesity is associated with low-grade chronic inflammation. Fat tissue produces adipocytokines that can promote inflammatory processes. Chronic diseases: Autoimmune and immunodeficiency disorders attack and potentially disable immune cells.

Chronic mental stress: Stress releases hormones like cortisol that suppresses inflammation inflammation is initially needed to activate immune cells and the action of white blood cells.

Lack of sleep and rest: Sleep is a time of restoration for the body , during which a type of cytokine is released that fights infection; too little sleep lowers the amount of these cytokines and other immune cells. Does an Immune-Boosting Diet Exist?

Probiotic foods include kefir, yogurt with live active cultures, fermented vegetables, sauerkraut, tempeh, kombucha tea, kimchi, and miso. Prebiotic foods include garlic, onions, leeks, asparagus, Jerusalem artichokes, dandelion greens, bananas , and seaweed.

However, a more general rule is to eat a variety of fruits, vegetables , beans , and whole grains for dietary prebiotics. Chicken soup as medicine? Is there scientific evidence that it aids in healing?

But when breaking down its ingredients, it does appear a worthwhile remedy to try. Citrus fruits are rich in vitamin C, which supports a healthy immune system.

Vitamin C is an antioxidant that can help with wound healing, protect the epithelial barrier against pathogens and can trigger anti-inflammatory signals. Some studies have shown that vitamin C appears to prevent and treat respiratory and systemic infections.

It can also help to reduce the length of cold symptoms, but cannot prevent someone from catching a cold. Adding citrus fruits to your meal is the way to go this season. Oats contain many nutrients and bioactive compounds, such as polyphenolics, which have been associated with antioxidant, anti-inflammatory and immunogenic responses.

Oats also contain dietary fibers and beta-glucan that help modulate the immune system, which is paramount for defending against infectious disease, including cold, flu and COVID Oats can also help optimize the immune system indirectly by modifying the content of microbiota.

All forms of oatmeal contain the same vitamins, minerals, phytochemicals and fiber. A good breakfast to help fight infections can be a warm oatmeal made with steel-cut, rolled oats, or unflavored instant oatmeal.

Sweet potato is packed with beta-carotene, a precursor of vitamin A, which is critical to the immune system. It is well known that carotenoids like beta-carotene seem to reduce damage from free radicals. Sweet potato is also rich in vitamin C, which is also a boost for the immune system.

Enhance your meals with a boost of color and nutrients using sweet potato in stews, roasted in the oven, either alone or with other vegetables, or steamed. Garlic has been used in traditional medicine to prevent or treat diseases. Due to different bioactive molecules, garlic compounds can help with DNA repair, slow the growth of cancer cells and reduce inflammation.

Garlic is rich in phytochemicals, inducing many health benefits, with anti-inflammatory and immunomodulatory properties. Garlic is largely used as a flavoring in many Asian and Mediterranean cuisines.
