5 types of tea to help strengthen immunity-Life health

Strengthening the body’s immunity, helping to prevent disease is very important, especially during the COVID-19 pandemic. There are many ways to strengthen resistance, but a few types of tea below you can refer to in the daily menu…

Some teas contain healthy plant compounds.

1. How can tea support immune health?

Much of the immune and overall health benefits of tea are tied to a group of antioxidants called polyphenols.

A significant amount of data has shown that a diet rich in polyphenols is protective against chronic health conditions such as cardiovascular disease and type 2 diabetes. Previous research has shown an effect. The effect of this antioxidant nutrient on the immune system response to influenza. Teas that are particularly rich in polyphenols called flavonols have also been shown to help lower blood pressure and cholesterol.

According to Harvard Health, antioxidants (like the flavonols in tea) can help protect your body against free radicals produced by pollution, cigarette smoke, and ultraviolet rays. Free radicals have harmful effects on the body, including weakening the immune system.

There are a variety of teas that help support immune health. Popular choices like green tea, black tea, white tea and oolong tea… all come from the same plant Camellia sinensis. However, they become different in the way of processing, geographical location and cultivars… which make up the taste and nutritional composition of tea. This means that some teas will provide more immune benefits than others.

Immune health is everyone’s top concern. You can start with this list of teas for a healthy immune system:

2.Some teas can help boost immunity

2.1 Green tea

Green tea is rich in catechins. This is an antioxidant, has the effect of lowering blood cholesterol, anti-standard and preventing cancer…

Epigallocatechin gallate (EGCG) is one of the most abundant and best known catechins in green tea.

A previous mouse study showed that giving EGCG to mice increased the number of regulatory T cells in the spleen and lymph nodes. Regulatory T cells help regulate the immune response, keeping the immune system in balance and preventing it from attacking healthy cells.

Research in humans showed that EGCG prevented T cells from making anti-inflammatory proteins called cytokines, which suggests that plant compounds in green tea may help regulate the immune system.

While these results provide clues to the link between green tea and immunity, further research is needed in humans, particularly in people with weakened immune systems, and across a large population. than.

2.2 Turmeric tea

Turmeric is a very common spice in many dishes, typically curries, and offers many health benefits. However, turmeric is also used in tea form.

Studies show that turmeric can reduce inflammation and contains high levels of antioxidants, both of which support overall immune function.

The main active compound in turmeric is curcumin. This substance effectively scavenges free radicals, controls enzymes that neutralize free radicals, and helps prevent the generation of free radicals. Free radicals are the cause of many diseases.

Researchers have also found that curcumin may play an important role in the immune response. Research in mice, using spleen cells cultured from mice, revealed that curcumin can regulate T cells and B cells, two lymphocytes that recognize and respond to foreign substances inside the body. . The scientists found that curcumin helped regulate the immune response to prevent immune cells from attacking healthy tissues. These results suggest that curcumin may be a promising therapy to keep the immune system under control.

2.3 Black tea

Black tea is the result of a fermentation reaction from green tea. This tea contains polyphenols called theaflavins, which are antioxidants similar to ECGC (in green tea).

A study in healthy people (who had no major disease and normal to mild systolic blood pressure) who drank three cups of black tea daily for six months showed increased immune activity.

2.4 White tea

White tea is known to be one of the most delicate teas because it is minimally processed. White tea is harvested before the leaves have fully bloomed, when the young buds are still covered with fine white hairs, hence the name “white” tea.

These buds and young leaves are hand-selected and then quickly dried, so the leaves are not oxidized.

However, like green tea, white tea provides high levels of catechins. The antioxidant benefits are similar to those of green tea, although the antioxidant potential of green tea is still greater.

Test-tube studies showed that white tea extract helped protect the nerve cells of rats from damage when exposed to hydrogen peroxide, a free radical; Helps to control inflammation in human skin cells caused by free radicals. Additionally, white tea may offer antibacterial benefits.

The researchers tested the antibacterial effects of white tea leaves against oral Streptococcus mutans and Streptococcus sobrinus, two bacteria that contribute to tooth decay. After a 72-hour incubation period, the researchers found that the white tea extract showed significant antibacterial effects against Streptococcus mutans bacteria. This suggests that white tea extract may help protect against tooth decay. However, more human studies are needed.

2.5 Ginger tea

Ginger is also a spice for cooking, however, ginger is also commonly used in the form of tea.

Gingerol is the main active compound that gives ginger its spicy taste, aroma, and medicinal properties. Studies also show that gingerol not only has antioxidant and anti-inflammatory effects, but can also treat infections.

In addition to gingerol, ginger contains other antiviral compounds that are effective in fighting the common cold.
