Tea has many health benefits beyond its pleasant taste. Many of us have gone for a hot cup of tea in the hope of reducing a sore throat or preventing a cold. Using tea as a medicine is nothing new. The Chinese have used this method for centuries to treat diseases and strengthen the immune system.
Despite the widespread use of tea to maintain immune function, there is little scientific evidence for this. If you want to know more about the effect of tea on the immune system, read this article from BingMag to the end.
How can tea help strengthen the immune system?
More benefits Tea belongs to a group of antioxidants called "polyphenols" to maintain the general health of the body and strengthen the immune system. Scientific research shows that a diet rich in polyphenols can protect the body against chronic diseases such as cardiovascular disease and type 2 diabetes. Tea contains polyphenols called flavonols, which can help lower blood pressure and cholesterol.
As far as the immune system is concerned, antioxidants (such as flavonols) Contained in tea) are involved in protecting the body against free radicals caused by pollution, cigarette smoke and the sun's ultraviolet rays. Free radicals can have detrimental effects on the body and weaken the immune system.
There are several types of tea that can help keep your immune system healthy. According to Harvard University, popular options such as green tea, black tea, white tea and oolong tea are all derived from a plant called Camellia sinensis.
What distinguishes them is the way they are prepared. Differences in processing, geographical location and plant species lead to unique flavors and different nutritional values. For this reason, some types of tea may have greater benefits for the immune system than others. Herbal teas may also be effective in maintaining a healthy immune system. Herbal teas are not made from camellia, but from dried herbs, spices, roots, seeds, fruits, or leaves of other plants. Depending on the composition and nutritional value of a particular plant, some herbal teas can help boost the immune system.
Further research is needed on the relationship between tea and the immune system
Although the results of research on tea and immune system health are promising, so far in various studies, either humans or relatively few participants have been used. It has been low. Many studies also use tea in the form of capsules or tablets, which usually have a higher dose of herbal ingredients than bagged tea. Given these limitations, it is difficult to know the effect of drinking a cup of tea on the health of the immune system of an ordinary person, and more extensive studies should be done on people who use brewed tea.
In general, health professionals It is believed that brewed and unsweetened tea is a healthy drink and is a great way to add herbs to your daily diet. If keeping your immune system healthy is your biggest concern, you can start taking one of the teas introduced in this article.
Green tea is a rich source of catechin. Catechins are polyphenols or antioxidants that have positive health benefits. Epigallocatechin gallate (EGCG) is one of the most abundant and well-known catechins in green tea, which can help maintain a healthy immune system. For example, one study found that treating mice with EGCG increased the number of regulatory T cells in the spleen and lymph nodes. Regulatory T cells modulate the immune response and prevent the immune system from attacking healthy cells in the body.
Research shows that EGCG can affect immune function in humans as well. In one study, researchers exposed T cells taken from 20 healthy adult men to EGCG isolated from water-soluble green tea, and concluded that EGCG prevents T cells from producing proinflammatory proteins called cytokines. . This finding suggests that the herbal compounds in green tea can help regulate the immune system.
Although these findings provide important clues as to the relationship between green tea and the immune system, more research is needed. Humans and people with weaker immune systems.
2. Turmeric Tea
It seems that turmeric is also good for the immune system when consumed in the form of tea. Is. Research shows that turmeric contains a lot of antioxidants and reduces inflammation Gives. For this reason, it can support the immune system. Curcumin is the active ingredient in turmeric, which has been shown to effectively kill various types of free radicals, control free radical scavenging enzymes, and Helps prevent the formation of free radicals. Due to the role that free radicals play in many diseases, the antioxidants in turmeric can make it a useful supplement for maintaining a healthy immune system.
According to researchers, curcumin may play a role Have an important safety response. For example, a study using mouse spleen cells showed that curcumin regulates T cells and B cells. These two types of lymphocytes can detect and respond to foreign substances in the body.
In this study, curcumin prevented immune cells from invading healthy tissues by modulating the immune response, and the researchers concluded that Using this substance can be a promising solution to control the immune system. However, there is no research that has been done on humans and specifically on the benefits of turmeric tea. For this reason, scientists do not currently know whether drinking turmeric tea by humans can have the benefits observed in this study.
3. Black Tea
This popular tea's dark color comes from a group of polyphenols called Theaflavin. Research shows that, like ECGC, it has antioxidant properties. The antioxidants in black tea may have unique effects on the immune system.
For example, one study found that consuming three cups of black tea a day for six months boosted immune activity. Increases in healthy people (without serious illness and with normal systolic blood pressure). In this study, researchers used three markers, Neopterin, Kynurenine, and Tryptophan, to monitor immune activation. Although black tea had no significant effect on neoprene or tryptophan levels, it did increase quinornen. This finding showed that the polyphenols in black tea help activate the immune response in healthy people.
Doing this study on humans is a positive point. But the number of participants is small (45 people drank tea and 49 were in the control group). Therefore, to better understand the effect of drinking tea on the immune system and various diseases, larger studies are needed on different patients.
4. White Tea White tea, like green tea, contains a lot of
catechins. Research shows that this tea, similar to green tea, has
antioxidant benefits, but the antioxidant potential of green tea is
There is no strong human research on the relationship between white tea and the immune system, but there is little evidence. Shows that further research on the properties of this tea can be valuable. For example, in a study in a test tube, white tea extract was able to help protect rat nerve cells from damage caused by a free radical called hydrogen peroxide. In another study, white tea extract reduced inflammation caused by free radicals in human skin cells.
In addition, white tea may have antimicrobial properties. Researchers have studied the antimicrobial effects of white tea leaves by exposing it to the bacteria Streptococcus mutans and Streptococcus sobrinus, two microorganisms that cause tooth decay. It has significant antibacterial properties and can prevent tooth decay.
Although studies in the test tube have yielded interesting results, they do not provide a complete picture of the benefits of the test substance. An herb or supplement that passes through our digestive system must enter the bloodstream, be processed in the liver, and continue to be effective if diluted in the body. For this reason, it is necessary to do more studies on humans and brewed tea.
5. Ginger tea
Ginger as a close relative of turmeric, can have many benefits in strengthening the immune system . Gingerol is the active ingredient from which the spicy, peppery taste and medicinal properties of ginger are derived. According to research, ginger not only has antioxidant and anti-inflammatory effects, but can also help cure infections.
Scientific evidence shows that ginger contains other anti-viral compounds in addition to ginger that are effective in fighting colds. And help reduce the pain, fever, and cough associated with it. However, few studies have been conducted on the effects of ginger, especially ginger tea, on the immune system, and more research is needed to reach a definitive conclusion about the role of ginger tea in maintaining an immune system.
Your body is constantly battling free radicals, which are by-products of metabolism. Under normal circumstances, the body can control free radicals, but aging, eating habits, smoking and some environmental factors may affect the immune system. Over time, free radicals cause oxidative stress, thereby damaging the body's cells and reducing their effectiveness. As a result, they can increase the risk of chronic disease and premature aging. Fortunately, the antioxidants in tea, especially polyphenols, are powerful plant compounds that can prevent or delay oxidative damage. Free radicals help. Increasing the intake of antioxidants through tea strengthens the immune system and reduces the risk of various diseases such as cardiovascular disease, type 2 diabetes and cancer.This article is for educational and informational purposes only.
