A cup of warm tea is delicious when taken while relaxing! Drinking tea is indeed refreshing and makes relax your tired body. There are also many benefits to health.
Tea is made into a drink by brewing leaves, shoots, or dried stems from the Camellia sinensis plant.
However, the term “tea” is now also used for drinks made from fruit, spices or medicinal plants that are brewed, such as RoseIla tea, Camomile tea, or Chrysanthemum tea.
Tea that does not contain tea leaves is commonly called herbal tea. Next, we will only discuss the health benefits of tea that comes from the leaves of Camellia Sinensis.
Types of Tea that can Reduce Body Fat
There are several types of tea made from Camellia Sinensis leaves which are differentiated based on the drying process of the leaves.
This green tea is the most popular types of tea in China and Japan. Also considered to be the most beneficial tea for health, especially because of its efficacy against cancer, reducing bad cholesterol and slimming.
The green tea is obtained from shoots of fresh tea leaves which are warmed with water vapor at high temperatures.
Oolong tea (oolong tea)
Traditional Chinese tea experiences partial oxidation or fermentation. Because it is only half fermented, the edges of the tea leaves are reddish, while the middle part remains green.
The taste of steeping oolong tea is more similar to green tea; the color and aroma are less strong than black tea.
Oolong tea leaves are processed by rolling tea leaves into curls. Usually served in Chinese restaurants for friends to eat dim sum and other Chinese dishes.
Made from the youngest shoots of tea leaves that are still filled with fine hair. White tea does not undergo a fermentation process, only evaporated and dried.
The white tea leaves after drying are not green but silvery white and if brewed are pale yellow with a soft and fresh aroma.
Also referred to as red tea by the Chinese, Japanese and Korean nations. It is the most popular and often consumed type of tea in South Asia including Indonesia.
Black tea has a longer oxidation process than green tea, oolong tea, and white tea. This type of tea has a stronger aroma and can last up to several years if stored properly.
Benefits of Tea for Health and Losing Weight
Abundant health benefits Tea is rich in antioxidants in the form of polyphenols and flavonoids. Some of the benefits are as follows:
- The content of polyphenols in tea is 10 times higher than polyphenols in fruits and vegetables. The main polyphenols in tea are catechins that can inhibit the oxidation process that damages the body’s cells, reduces the amount and inhibits the growth of cancer cells.
- Green tea and white tea contain high amounts of catechins, even white tea is believed to have better antioxidant abilities than green tea. Whereas black tea contains fewer catechins because many catechins are lost in the oxidation process.
- Ep/gal/ catechin ga / late (EGCG) is one type of catechin in green tea that can help fight several kinds of cancers such as lung, prostate and breast cancer.
- Three cups of black tea every day is believed to reduce the risk of cardiovascular diseases such as heart disease, reduce LDL (bad cholesterol), hypertension, and stroke. This can happen because of the role of Quercetin kaempferol and myricetin flavonoids that can prevent damage to blood vessels due to cholesterol oxidation.
- In addition, according to Richard Anderson, a biochemist from the USDA Beltsville Human Nutrition Research Center, Maryland, drinking black, green and oolong tea is beneficial for diabetics because it can increase insulin activity up to 15 times. Allegedly this has something to do with the content of EGCG in tea.
- Tea contains fluoride which is beneficial for dental health. Based on research at Tokyo Dental College, Huoride has the ability to kill Streptococcus mutant bacteria which causes tooth decay which helps control bad breath and dental plaque formation.
- Based on research tea also contains the amino acid L-theanine which is proven to be able to strengthen the body’s immune system against infections and increase alpha waves in the brain associated with relaxation conditions. Consumption of black tea can also affect levels of stress hormones in the body that help deal with stressful conditions quickly. Research shows that 50 minutes after stress occurs, people who drank 4 glasses of black tea a day for 4 weeks decreased the stress hormone cortisol levels by 47 percent.
- Tea is also useful to prevent brain damage due to the aging process. Elderly people in Japan who consume 2 glasses or more of green tea everyday experience a 50 percent lower risk of brain damage, compared to elderly people who consume less than 2 cups of green tea a day. This is caused by the content of EGCG in green tea. The results of the latest research conducted at Tokyo University, Japan, states that EGCG in green tea can help improve the immune system that prevents HIV / AIDS. This is supported by research conducted by Professor Mike Williamson of the University of Sheffield, that drinking green tea can reduce the risk of HIV infection while at the same time inhibiting the spread of HIV.
- Based on a study published in the journal Nutrition & Metabolism in 2009, it was said that white tea extract can help break down fat cells and prevent fat tissue accumulation. This means that white tea can help one’s diet program to slim down.
- Green tea contains caffeine and ECGC which are proven to help you lose weight and maintain it, according to 11 studies in the International Journal of Obesity.
- Oolong tea can increase the body’s ability to break down fat, in a study in China in 2009. In the study, volunteers consisting of obese people were asked to consume oolong for six weeks. About 2/3 more volunteers can lose nearly one kilogram of weight and about 12 percent fat.
- Black tea is also proven to prevent obesity because it contains polyphenol-theaflavin and thearubigins plant compounds — which are useful in preventing fat absorption.
How to drink tea
Although efficacious for health, that does not mean tea can be consumed at will. The following are tips for drinking tea that many health experts recommend:
- Tea is not recommended for people who have certain conditions such as people with kidney disease. Tea is a diuretic (which facilitates the removal of urine).
- Drinking lots of tea can interfere with kidney function so that it will further aggravate kidney disease conditions. Tea also contains oxalate, which if consumed in excess is feared to cause kidney damage.
- Tanin contained in tea can bind iron in food so that the body can not absorb iron. This can lead to anemia and iron deficiency. In pregnant women, tea can also cause the fetus to contain an inherent iron deficiency. So that after birth the baby will also suffer from anemia and iron deficiency. Women who are breastfeeding should not drink thick tea.
- Although not as much as in coffee, tea contains about 40 mg of caffeine per cup. The content of caffeine in tea is thought to affect the expenditure of milk, so the milk is reduced.
Thus the benefits of tea for health and body slimming. So besides delicious tea, it turns out that there are many benefits, too!
