Beyond the usual suspects for healthy resolutions. September 11, By Robert H. Shmerling, MD , Senior Faculty Editor, Harvard Health Publishing; Editorial Advisory Board Member, Harvard Health Publishing Ever see ads for products that promise to supercharge immunity? IV drips, supplements, cleanses, and superfoods The lineup of immune-boosting products and advice includes: Home intravenous IV drips. Want a health professional to come to your home with IV fluids containing various vitamins and supplements? That's available in many US cities, and some companies claim their formula is designed to supercharge immunity. These on-demand IV treatments aren't risk-free and can be quite expensive. Vitamins and supplements. Popular options include turmeric, milk thistle, and echinacea, often in combination with various vitamins. Hundreds of formulations are available. Superfoods and foods to avoid. If you search online for "foods to boost the immune system" you'll see thousands of articles touting blueberries, broccoli, spinach, dark chocolate, and other foods to keep infections away. There's also a list of foods to avoid, such as sugary drinks or highly processed meats, because they're supposed to be bad for your immune system. Cleanses and detox treatments. No doubt you've seen pitches for cleanses and detox products intended to remove toxins from the body. Their marketing warns that the environment is full of harmful substances that get into the body through the air, water, and food, which we need to remove. Advocates suggest that, among other harmful effects, these often unnamed toxins make your immune system sluggish. Are the heavily marketed IV drips, supplements, or detox products endorsed by the FDA? More importantly, they're confusing: Boosting immunity is what vaccinations do. They prime your immune system to help fight off a specific infectious organism like the flu shot before each flu season. Immune support typically describes vitamins such as vitamin C , or other nutrients necessary for a healthy immune system. A variety of studies , mostly 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 curcumin , which 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 flavonoids , a type of antioxidant. Where green tea really excels is in its levels of epigallocatechin gallate EGCG , another 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 potassium , magnesium, and folate , all of which are beneficial to your overall health. Like papayas, kiwis are a rich source of essential nutrients, including folate, potassium, vitamin K , and 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 gelatin , chondroitin, 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-cells , which 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 count , you 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. Antiviral foods may include fermented vegetables kimchi , fermented milk yogurt and kefir , herbs oregano, fennel, peppermint, and aloe vera , garlic, ginger, turmeric, black cumin, cinnamon, licorice root, mushrooms, and citrus fruits. Some foods may boost your immune system while others will help with their antimicrobial properties. This means they may help fight bacteria, viruses, and other pathogens that cause infections. Examples include herbs and spices oregano , cinnamon , clove , and rosemary , cruciferous vegetables kale and rutabaga , citrus fruits, parsley , and a wide range of other plant-based foods. Eating a variety of vegetables may help you boost your immune system. Red peppers, spinach, and broccoli are good choices, as well as ginger, turmeric, and garlic. Eating all types of fresh fruits regularly may help your immune system function well. Bananas, in particular, contain a substance called lectin. One study in rodents found that banana lectin may enhance the immune system. Fresh foods can provide our bodies with the nutrients our immune system needs to work correctly. You need a variety of fruits, vegetables, whole grains, herbs, and spices in your diet to enable your body to stay as healthy as possible. Good choices of foods to boost the immune system include citrus fruits, spinach, almonds, papaya, and green tea. Not quite, says Dr. Michael Ben-Aderet , an infectious disease specialist and associate medical director of Hospital Epidemiology at Cedars-Sinai Medical Center. But I think there is still that concern, 'Are people getting enough? Do they need more vitamins? That doesn't mean that it's impossible that they're providing any benefit. It just means that we haven't been able to prove the benefit. DON'T MISS: Do Americans have a vitamin D problem? Though he notes that some people have severe, medical vitamin C and vitamin D deficiencies — which can lead to swollen, bleeding gums or bone fractures — and for those individuals, vitamin supplementation is a very effective and necessary measure. A Cochrane review of randomized controlled trials that examined the effects of taking vitamin C supplements daily on the prevention and treatment of the common cold found that taking the supplement every day didn't reduce the incidence of colds. However, "it did at least reduce the severity and duration of colds," says Dr. John Mafi , an associate professor of medicine in the Division of General Internal Medicine and Health Services Research at the David Geffen School of Medicine at UCLA. It's not untrue that vitamin C and vitamin D actually can help to support the function of your immune system. Vitamin D helps your body to create an antimicrobial peptide called cathelicidin, which "stops bacteria, microbes and viruses," and "[regulates] the function of your body's T-cells," Mafi says. Vitamin D supplements have a bit more evidence for their potential benefits.

Six Tips to Enhance Immunity | DNPAO | CDC	One important question is whether dietary supplements may help older people maintain a healthier immune system. Older people should discuss this question with their doctor. Like any fighting force, the immune system army marches on its stomach. Healthy immune system warriors need good, regular nourishment. Scientists have long recognized that people who live in poverty and are malnourished are more vulnerable to infectious diseases. For example, researchers don't know whether any particular dietary factors, such as processed foods or high simple sugar intake, will have adversely affect immune function. There are still relatively few studies of the effects of nutrition on the immune system of humans. There is some evidence that various micronutrient deficiencies — for example, deficiencies of zinc, selenium, iron, copper, folic acid, and vitamins A, B6, C, and E — alter immune responses in animals, as measured in the test tube. However, the impact of these immune system changes on the health of animals is less clear, and the effect of similar deficiencies on the human immune response has yet to be assessed. So, what can you do? If you suspect your diet is not providing you with all your micronutrient needs — maybe, for instance, you don't like vegetables — taking a daily multivitamin and mineral supplement may bring other health benefits, beyond any possibly beneficial effects on the immune system. Taking megadoses of a single vitamin does not. More is not necessarily better. 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. Modern medicine has come to appreciate the closely linked relationship of mind and body. A wide variety of maladies, including stomach upset, hives, and even heart disease, are linked to the effects of emotional stress. Despite the challenges, scientists are actively studying the relationship between stress and immune function. For one thing, stress is difficult to define. What may appear to be a stressful situation for one person is not for another. When people are exposed to situations they regard as stressful, it is difficult for them to measure how much stress they feel, and difficult for the scientist to know if a person's subjective impression of the amount of stress is accurate. The scientist can only measure things that may reflect stress, such as the number of times the heart beats each minute, but such measures also may reflect other factors. Most scientists studying the relationship of stress and immune function, however, do not study a sudden, short-lived stressor; rather, they try to study more constant and frequent stressors known as chronic stress, such as that caused by relationships with family, friends, and co-workers, or sustained challenges to perform well at one's work. Some scientists are investigating whether ongoing stress takes a toll on the immune system. But it is hard to perform what scientists call "controlled experiments" in human beings. In a controlled experiment, the scientist can change one and only one factor, such as the amount of a particular chemical, and then measure the effect of that change on some other measurable phenomenon, such as the amount of antibodies produced by a particular type of immune system cell when it is exposed to the chemical. In a living animal, and especially in a human being, that kind of control is just not possible, since there are so many other things happening to the animal or person at the time that measurements are being taken. Despite these inevitable difficulties in measuring the relationship of stress to immunity, scientists are making progress. Almost every mother has said it: "Wear a jacket or you'll catch a cold! Probably not, exposure to moderate cold temperatures doesn't increase your susceptibility to infection. There are two reasons why winter is "cold and flu season. Also the influenza virus stays airborne longer when air is cold and less humid. But researchers remain interested in this question in different populations. Some experiments with mice suggest that cold exposure might reduce the ability to cope with infection. But what about humans? Scientists have performed experiments in which volunteers were briefly dunked in cold water or spent short periods of time naked in subfreezing temperatures. They've studied people who lived in Antarctica and those on expeditions in the Canadian Rockies. The results have been mixed. For example, researchers documented an increase in upper respiratory infections in competitive cross-country skiers who exercise vigorously in the cold, but whether these infections are due to the cold or other factors — such as the intense exercise or the dryness of the air — is not known. A group of Canadian researchers that has reviewed hundreds of medical studies on the subject and conducted some of its own research concludes that there's no need to worry about moderate cold exposure — it has no detrimental effect on the human immune system. Should you bundle up when it's cold outside? The answer is "yes" if you're uncomfortable, or if you're going to be outdoors for an extended period where such problems as frostbite and hypothermia are a risk. But don't worry about immunity. Regular exercise is one of the pillars of healthy living. It improves cardiovascular health, lowers blood pressure, helps control body weight, and protects against a variety of diseases. But does it help to boost your immune system naturally and keep it healthy? Just like a healthy diet, exercise can contribute to general good health and therefore to a healthy immune system.

Every part of your body, including your immune system, functions better when protected from environmental assaults and bolstered by healthy-living strategies such as these: Don't smoke. Eat a diet high in fruits and vegetables. A systemic review of elderberry 43 concluded:. Taking elderberry supplements may help reduce upper respiratory symptoms caused by viral infections and help alleviate flu symptoms. However, elderberry also has risks. More research is needed. Medicinal mushrooms have been used since ancient times to prevent and treat infection and disease. Many types of medicinal mushrooms have been studied for their immune-boosting potential. Over recognized species of medicinal mushrooms are known to have immune-enhancing properties Some research demonstrates that supplementing with specific types of medicinal mushrooms may enhance immune health in several ways as well as reduce symptoms of certain conditions, including asthma and lung infections. For example, a study in mice with tuberculosis, a serious bacterial disease, found that treatment with cordyceps significantly reduced bacterial load in the lungs, enhanced immune response, and reduced inflammation, compared with a placebo group In a randomized, 8-week study in 79 adults, supplementing with 1. Turkey tail is another medicinal mushroom that has powerful effects on immune health. Research in humans indicates that turkey tail may enhance immune response, especially in people with certain types of cancer 48 , Many other medicinal mushrooms have been studied for their beneficial effects on immune health as well. Medicinal mushroom products can be found in the form of tinctures, teas, and supplements 50 , 51 , 52 , Many types of medicinal mushrooms, including cordyceps and turkey tail, may offer immune-enhancing and antibacterial effects. According to results from scientific research, the supplements listed above may offer immune-boosting properties. However, keep in mind that many of these potential effects these supplements have on immune health have not been thoroughly tested in humans, highlighting the need for future studies. Astragalus, garlic, curcumin, and echinacea are just some of the supplements that may offer immune-boosting properties. Still, they have not been thoroughly tested in humans. Many supplements on the market may help improve immune health. Zinc, elderberry, and vitamins C and D are just some of the substances that have been researched for their immune-enhancing potential. However, although these supplements may offer a small benefit for immune health, they should not and cannot be used as a replacement for a healthy lifestyle. Aiming to eat a nutrient-dense balanced diet, getting enough sleep, engaging in regular physical activity, and not smoking or considering quitting, if you smoke are some of the most important ways to help keep your immune system healthy and reduce your chances of infection and disease. If you decide that you want to try a supplement, speak with a healthcare professional first, as some supplements may interact with certain medications or are inappropriate for some people.

Immune system boosters -

Perhaps there will come a time when we'll know how to boost immune function beyond following routine health measures. That's simply not the case now. Until we know more, I wouldn't rely on individual foods, detox programs, oral supplements, or on-demand IV drips to keep your immune system healthy, especially when there are far more reliable options.

September 11, By Robert H. Shmerling, MD , Senior Faculty Editor, Harvard Health Publishing; Editorial Advisory Board Member, Harvard Health Publishing Ever see ads for products that promise to supercharge immunity? IV drips, supplements, cleanses, and superfoods The lineup of immune-boosting products and advice includes: Home intravenous IV drips.

Want a health professional to come to your home with IV fluids containing various vitamins and supplements? That's available in many US cities, and some companies claim their formula is designed to supercharge immunity. These on-demand IV treatments aren't risk-free and can be quite expensive.

Vitamins and supplements. Popular options include turmeric, milk thistle, and echinacea, often in combination with various vitamins. Hundreds of formulations are available. Superfoods and foods to avoid. If you search online for "foods to boost the immune system" you'll see thousands of articles touting blueberries, broccoli, spinach, dark chocolate, and other foods to keep infections away.

There's also a list of foods to avoid, such as sugary drinks or highly processed meats, because they're supposed to be bad for your immune system. Cleanses and detox treatments. No doubt you've seen pitches for cleanses and detox products intended to remove toxins from the body. Their marketing warns that the environment is full of harmful substances that get into the body through the air, water, and food, which we need to remove.

Advocates suggest that, among other harmful effects, these often unnamed toxins make your immune system sluggish. Are the heavily marketed IV drips, supplements, or detox products endorsed by the FDA? More importantly, they're confusing: Boosting immunity is what vaccinations do.

They prime your immune system to help fight off a specific infectious organism like the flu shot before each flu season. Immune support typically describes vitamins such as vitamin C , or other nutrients necessary for a healthy immune system.

It's true that a deficiency of vital nutrients can cause poor immune function. But that doesn't mean a person with normal levels of nutrients can expect supplements to improve their immune system.

Can products marketed as immune boosters actually boost immunity? How to get the most out of your immune system It's not a secret and it's not a product. The best ways to keep your immune system at peak performance are: Eat well and follow a heart-healthy diet, such as the Mediterranean diet.

Exercise regularly and maintain a healthy weight. Most often, only a small part of the immune system is weak, which makes infections from specific, not all, bugs more likely. Some people have stronger immune systems than others, so they are resistant to more types of infections.

A few people, very few, are resistant to all types of infections. Unfortunately, most people find out that one part of their immune system is weak when they get an infection. But there is no single test that checks out the immune system.

Age plays a big role in the immune system. Young children, exposed to infections for the first time, tend to be symptomatic more than adults. And older adults may find their immune system cannot fight disease as well as it did when they were young. Scientists are studying direct connections between lifestyle choices and strong immune systems.

What we know now is that healthy living is good for overall health and vaccinations are the best supplement available. Most studies show that dietary supplements are only useful if you have a deficiency in a nutrient. Taking supplements on top of a healthy diet does not add much to your immune system.

Note that most supplements are not superior to the nutrients you can get from food. Studies show the immune system is very responsive to exercise. Exercise and immune regulation are interrelated and affect each other.

Exercise changes immune regulation by affecting cells and has anti-inflammatory effects. Sleep loss reduces natural killer cell activity, which increases the risk for cancer and viral infections; generates production of inflammatory cytokines, which increases the risk for cardiovascular and metabolic disorders; and reduces production of antibodies, which increases the risk for infections.

Stress of all sorts—psychological and physical—directly weakens parts of your immune system, increasing risk for infections or reactivation of viruses inside you.

Shingles, a painful rash that arises from the reactivated chickenpox virus, often flares up when people are experiencing chronic stress. Stress can also cause "patrols" in your immune system—certain cells that tell the immune system to wind down an attack—to fail. When this happens, too much inflammation can occur.

Vaccines, also called immunizations, teach the immune system to make antibodies that fight off infections before they make you sick. Taking zinc supplements at the beginning of a respiratory infection can reduce the severity and duration of symptoms.

The idea of boosting your immune Immune system boosters ssystem appealing, but is it even Pharmaceutical-grade material specifications to eystem up boosers immune Immune system boosters so that you rarely get sick? Suzanne Casselan immunologist at Cedars-Sinaisays that the concept of boosting your immune system is inaccurate.

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.

Modern medicine has come to appreciate the closely linked relationship of mind and body. A wide variety of maladies, including stomach upset, hives, and even heart disease, are linked to the effects of emotional stress. Despite the challenges, scientists are actively studying the relationship between stress and immune function.

For one thing, stress is difficult to define. What may appear to be a stressful situation for one person is not for another. When people are exposed to situations they regard as stressful, it is difficult for them to measure how much stress they feel, and difficult for the scientist to know if a person's subjective impression of the amount of stress is accurate.

The scientist can only measure things that may reflect stress, such as the number of times the heart beats each minute, but such measures also may reflect other factors.

Most scientists studying the relationship of stress and immune function, however, do not study a sudden, short-lived stressor; rather, they try to study more constant and frequent stressors known as chronic stress, such as that caused by relationships with family, friends, and co-workers, or sustained challenges to perform well at one's work.

Some scientists are investigating whether ongoing stress takes a toll on the immune system. But it is hard to perform what scientists call "controlled experiments" in human beings. In a controlled experiment, the scientist can change one and only one factor, such as the amount of a particular chemical, and then measure the effect of that change on some other measurable phenomenon, such as the amount of antibodies produced by a particular type of immune system cell when it is exposed to the chemical.

In a living animal, and especially in a human being, that kind of control is just not possible, since there are so many other things happening to the animal or person at the time that measurements are being taken. Despite these inevitable difficulties in measuring the relationship of stress to immunity, scientists are making progress.

Almost every mother has said it: "Wear a jacket or you'll catch a cold! Probably not, exposure to moderate cold temperatures doesn't increase your susceptibility to infection. There are two reasons why winter is "cold and flu season. Also the influenza virus stays airborne longer when air is cold and less humid.

But researchers remain interested in this question in different populations. Some experiments with mice suggest that cold exposure might reduce the ability to cope with infection. But what about humans? Scientists have performed experiments in which volunteers were briefly dunked in cold water or spent short periods of time naked in subfreezing temperatures.

They've studied people who lived in Antarctica and those on expeditions in the Canadian Rockies. The results have been mixed. For example, researchers documented an increase in upper respiratory infections in competitive cross-country skiers who exercise vigorously in the cold, but whether these infections are due to the cold or other factors — such as the intense exercise or the dryness of the air — is not known.

A group of Canadian researchers that has reviewed hundreds of medical studies on the subject and conducted some of its own research concludes that there's no need to worry about moderate cold exposure — it has no detrimental effect on the human immune system.

Should you bundle up when it's cold outside? The answer is "yes" if you're uncomfortable, or if you're going to be outdoors for an extended period where such problems as frostbite and hypothermia are a risk.

But don't worry about immunity. Regular exercise is one of the pillars of healthy living. It improves cardiovascular health, lowers blood pressure, helps control body weight, and protects against a variety of diseases.

But does it help to boost your immune system naturally and keep it healthy? Just like a healthy diet, exercise can contribute to general good health and therefore to a healthy immune system.

Every part of your body, including your immune system, functions better when protected from environmental assaults and bolstered by healthy-living strategies such as these: Don't smoke.

Eat a diet high in fruits and vegetables. Exercise regularly. Maintain a healthy weight. If you drink alcohol, drink only in moderation. Get adequate sleep. Practice good sleep hygiene and maintain consistent sleep hours—turn off screens, ensure the room is cool, quiet, and dark, and set a reminder to help yourself go to bed on time.

Check out our recorded Sleep workshop here! Exercise: Moderate, regular physical activity helps to boost immune system function by raising levels of infection-fighting white blood cells and antibodies, increasing circulation, and decreasing stress hormones.

Establish and follow an exercise program to not only help prevent respiratory infections but also to improve cognitive and physical resilience.

Eat plenty of fruits and vegetables—aim for 10 servings per week. Include fermented vegetables or other probiotic-containing foods.

There are several nutrients, plant-based botanicals, and supplements that can boost immune function and provide symptom relief during illness and may help to shorten the duration of illness. For preventing and treating viral upper respiratory infections, consider some of the following:.

Vitamin C: Vitamin C may help to prevent infections, including those caused by bacteria and viruses. Regularly administered vitamin C has been shown to shorten the duration of colds, and higher doses of vitamin C during an illness can also act as a natural antihistamine and anti-inflammatory.

Vitamin D : Vitamin D, known as the "sunshine vitamin," is one of the most important and powerful nutrients for supporting the immune system. Numerous studies have shown that it helps reduce the risk of colds and flu.

Unfortunately, a high percentage of the population is deficient, so daily supplementation ideally in the form of vitamin D3 offers the best protection. Vitamin A: For short-term use and particularly for those with moderate vitamin A deficiency, supplementation can be extremely helpful in supporting the body's ability to fight infections, particularly with regard to respiratory infections.

Zinc: Zinc plays a significant role in boosting immunity. Often available as lozenges, zinc can help to reduce the frequency of infections as well as the duration and severity of the common cold when taken within 24 hours of onset. Selenium: Selenium, a key nutrient for immune function, is also an antioxidant that helps boosts the body's defenses against bacteria, viruses, and cancer cells.

It may particularly help to protect against certain strains of flu virus. Selenium is easily obtained from foods, with the richest source being Brazil nuts. Honey: Honey, preferably raw, is a good demulcent it relieves minor pain and inflammation of mucous membranes , has antioxidant properties, and has some antimicrobial effects.

It is helpful for coughs and sore throats and can be added to hot tea. Garlic: Garlic contains a variety of compounds that can influence immunity. Some studies have shown that both fresh garlic as well as aged garlic extract and some other garlic supplements may reduce viral upper respiratory infection severity as well as function in the prevention of infection with viruses that can cause colds.

Probiotics: Probiotics contain "good bacteria" that not only support the health of the gut but also influence immune system functioning and regulation. Studies have shown that probiotic use can decrease the number of respiratory infections, particularly in children.

Blackberry and lemonade drink, oily Immune system boosters, turmeric, kefir, and other boosgers foods provide nutrients Immine support the immune system. The immune system consists of organs, cells, tissues, and proteins. Together, these carry out bodily processes that fight off pathogens, which are the viruses, bacteria, and foreign bodies that cause infection or disease. When the immune system comes into contact with a pathogen, it triggers an immune response.
