The TRUTH ABOUT HOW TO BOOST YOUR IMMUNE SYSTEM @DrDrayzdayNatural immune system support -
The immune system releases antibodies, which attach to antigens on the pathogens and kill them. Read on to discover 15 foods that boost the immune system.
A healthful, balanced diet plays a vital role in staying well. The following foods may help to boost the immune system:.
Researchers found that people who ate foods rich in flavonoids were less likely to get an upper respiratory tract infection, or common cold, than those who did not.
Free radicals are molecules that the body produces when it breaks down food or comes into contact with pollutants. Despite its potential benefits, dark chocolate is high in calories and saturated fat, so it is important to eat it in moderation. Turmeric is a yellow spice that many people use in cooking.
It is also present in some alternative medicines. This is due to the qualities of curcumin , a compound in turmeric. According to a review , curcumin has antioxidant and anti-inflammatory effects. Salmon, tuna, pilchards, and other oily fish are a rich source of omega-3 fatty acids.
According to a report , long-term intake of omega-3 fatty acids may reduce the risk of rheumatoid arthritis RA. RA is a chronic autoimmune condition that occurs when the immune system mistakenly attacks a healthy part of the body.
Broccoli is another source of vitamin C. It also contains potent antioxidants, such as sulforaphane. For these reasons, it is a good choice of vegetable to eat regularly to support immune system health. Sweet potatoes are rich in beta carotene , a type of antioxidant that gives the skin of the potatoes its orange color.
Beta carotene is a source of vitamin A. It helps to make skin healthy and may even provide some protection against skin damage from ultraviolet UV rays. Spinach may boost the immune system, as it contains many essential nutrients and antioxidants, including :.
Vitamins C and E can help support the immune system. Research also indicates that flavonoids may help to prevent the common cold in otherwise healthy people. People use ginger in a variety of dishes and desserts, as well as in teas.
According to a review, ginger has anti-inflammatory and antioxidative properties and is likely to offer health benefits.
However, more research is necessary to confirm whether or not it can effectively prevent illness. One review looked at whether taking garlic supplements containing allicin reduced the risk of getting a cold. The group of participants taking a placebo had more than double the number of colds between them than those taking the garlic supplements.
However, the researchers concluded that more research is necessary to determine whether or not garlic can help to prevent colds.
Green tea contains only a small amount of caffeine, so people can enjoy it as an alternative to black tea or coffee.
Drinking it may also strengthen the immune system. As with blueberries, green tea contains flavonoids, which may reduce the risk of a cold.
Kefir is a fermented drink that contains live cultures of bacteria that are beneficial for health. Initial research suggests that drinking kefir may boost the immune system.
According to a review , various studies have shown that regular consumption of kefir can help with:. The majority of the research that supports this was carried out on animals or in a laboratory. Researchers need to perform additional studies to understand how kefir may prevent disease in humans.
Sunflower seeds can make a tasty addition to salads or breakfast bowls. They are a rich source of vitamin E , an antioxidant. In the same way as other antioxidants, vitamin E improves immune function. It does this by fighting off free radicals, which can damage cells.
Almonds are another excellent source of vitamin E. They also contain manganese, magnesium , and fiber. A small handful or a quarter of a cup of almonds is a healthful snack that may benefit the immune system.
Oranges and kiwis are an excellent source of vitamin C, which is the vitamin that many people turn to when they feel a cold developing. While scientists are still not sure exactly how it helps, vitamin C may reduce the duration of common cold symptoms and improve the function of the human immune system.
For people trying to avoid the sugar in fruit, red bell peppers are an excellent alternative source of vitamin C. Stir-frying and roasting both preserve the nutrient content of red bell peppers better than steaming or boiling, according to a study on cooking methods.
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.
Although eating a balanced diet is key to boosting your immunity, foods alone cannot and should not replace medical treatment, unless your healthcare professional recommends it.

| 15 Foods That Boost the Immune System | Nuts, such as almonds , are 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 phosphorous , magnesium , and 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 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.

All these foods will not only build up parts of your immune system, but can help you maintain a healthy weight. 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.
