When it comes Strenhthening preventing and fighting off colds, vitamin E tends to take a backseat to vitamin C. However, this powerful antioxidant is key to a healthy immune system.

Nuts, such as almondsare packed with the vitamin and also have healthy fats. Adults only need about 15 mg of vitamin E each day. Sunflower seeds are full of nutrients, including phosphorousmagnesiumand vitamins B6 and E.

Vitamin E is important in regulating and maintaining immune system function. Other foods with high amounts of vitamin E include avocados and dark leafy greens. Sunflower seeds are also high in selenium. Just 1 ounce contains nearly half the selenium that the average adult needs daily.

A variety of studiesmostly performed on animals, have looked at its potential to combat viral infections such as swine flu H1N1. You may know turmeric as a key ingredient in many curries.

This bright yellow, bitter spice has also been used for years as an anti-inflammatory in treating both osteoarthritis and rheumatoid arthritis. Research shows that high concentrations of curcuminwhich gives turmeric its distinctive color, can help decrease exercise-induced muscle damage.

Curcumin has promise as an immune booster based on findings from animal studies with antimicrobial properties. More research is needed. Both green and black teas are packed with flavonoidsa type of antioxidant.

Where green tea really excels is in its levels of epigallocatechin gallate EGCGanother powerful antioxidant. Research has suggested that EGCG may have antiviral properties that support the immune system. The fermentation process black tea goes through destroys a lot of the EGCG.

Green tea, on the other hand, is steamed and not fermented, so the EGCG is preserved. Papayas also have a digestive enzyme called papain that has anti-inflammatory effects. Papayas have decent amounts of potassiummagnesium, and folateall of which are beneficial to your overall health.

Like papayas, kiwis are a rich source of essential nutrients, including folate, potassium, vitamin Kand vitamin C. The soup may help lower inflammation, which could improve symptoms of a cold. Poultry, such as chicken and turkey, is high in vitamin B6. About 3 ounces of light turkey or chicken meat contains nearly one-third of your daily recommended amount of B6.

Vitamin B6 is an important player in many of the chemical reactions that happen in the body. Stock or broth made by boiling chicken bones contains gelatinchondroitin, and other nutrients helpful for gut healing and immunity.

Too much zinc can actually inhibit immune system function. You may want to focus on eating a balanced diet with plenty of fresh foods and whole grains, engage in at least minutes of physical activity per week, get enough sleep, manage stress with deep breathing or talk therapy, avoid or quit smoking, and limit alcohol consumption.

Preliminary research suggests vitamin C may be involved in the development and function of white blood cells. It seems vitamin C may improve the reproduction of B- and T-cellswhich are important white blood cells for the immune system.

The amount of vitamin C needed for increasing white blood cells may depend on the condition and overall health needs. More research in humans is needed to better understand the link between vitamin C and white blood cells.

To raise your white blood cell countyou may want to avoid alcohol and tobacco use, take Omega-3s and zinc, and eat a balanced diet. For example, a study found that the Mediterranean diet had an effect on the white blood cell counts of adults at risk for cardiovascular disease. Depending on the cause of low white blood cells, you may also need to take medications like myeloid growth factors.

9 Tips to Strengthen Your Immunity Naturally	Moderate physical activity is recommended to combat obesity, heart disease and diabetes. Health experts recommend a moderate-intensity exercise routine, two to three times a week, for up to 45 minutes for good immune health. Try to aim for at least minutes of moderate exercise per week, or 30 minutes, five days a week. Maintaining an exercise routine might be particularly essential for the elderly. However, avoid pushing yourself too hard for too long. Prolonged more than 1. To determine whether the exercise is moderate or vigorous, you can use the "talk test. Stress causes your body to release cortisol , the body's primary stress hormone. Increased cortisol levels in the bloodstream can cause inflammation, which alters how your body's immune system responds to infections. Moreover, long-term inflammation promotes imbalances in immune cell function and can even suppress immune response. Children and the elderly are particularly vulnerable to stress on the immune system. According to Johns Hopkins Medicine , controlling stress is key to improving your immune system. Here's how stress can affect the body:. Once you know your triggers — workloads, kids, or relationships — you can make small changes can help manage your stress levels.

Physical activity is another strategy to manage stress and may reduce the risk of some chronic diseases that can weaken your immune system. Here are some myths and facts about immune-boosting nutrients: Fact: Chicken soup can help you feel better. 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.

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.

Moderate exercise improves cardiovascular health, lowers blood pressure and helps control body weight.

It also promotes the circulation of the cells and substances of the immune system, which allows them to move through the body freely and do their job efficiently. Unfortunately, only about 1 in 5 adults and teens get enough exercise to maintain good health, according to the American Heart Association.

Here is how a lack of activity can affect the body and lower your immune response:. Moderate physical activity is recommended to combat obesity, heart disease and diabetes.
