Green tea, which originated from China and India, has been consumed as a health benefit for a long time around the world. What are the health benefits of green tea, which has continued to be popular in Korea? Green tea is the most consumed drink in the world. However, 78 percent of cars consumed worldwide are black and only about 20 percent are green. All kinds of tea, except herbal tea, are extracted from dried leaves of camellia trees. The oxidation level of the leaves determines the type of tea.
Green tea is made from unoxidized leaves and is one of the less processed teas. Therefore, it contains the most antioxidants and beneficial polyphenols. Green tea has traditionally been used in Chinese and Indian medicine to minimize bleeding and treat wounds, help digestion, improve heart and mental health, and control body temperature. Recent studies have shown that green tea can have a positive effect on everything from weight loss to liver failure, type 2 diabetes, and Alzheimer's disease. However, you should be aware that more evidence is needed before these health benefits can be clearly demonstrated.
green tea efficacy
1. Cancer Prevention
According to the National Cancer Institute, polyphenols in green tea have been shown to reduce tumor growth in laboratory and animal studies and can be protected from UVB radiation damage. Although cancer rates tend to be low in countries with high consumption of green tea, it is not clear whether it is green tea that prevents cancer in certain populations or other living factors. Some studies have shown that green tea has a positive effect on the following types of cancer:
"Break cancer / bladder cancer / ovarian cancer / esophagus / lung cancer / prostate / skin / stomach cancer" researchers believe that the high polyphenol content of green tea is effective in killing cancer cells and preventing them from growing. However, the exact mechanism by which green tea interacts with cancer cells is unknown.
2. Cardiovascular disease prevention
A 2006 study published in the Journal of the American Medical Association concluded that drinking green tea is linked to a reduction in mortality from all causes, including cardiovascular disease. The study was conducted on more than 40,000 Japanese participants between the ages of 40 and 79 for 11 years from 1994. Participants who drank more than five cups of green tea a day had a significantly lower risk of death than those who drank less than one cup of tea a day.
3. Cholesterol reduction effect
An analysis of a study published in 2011 found that consuming green tea in the form of beverages or capsules is associated with a decrease in LDL cholesterol, a bad cholesterol.
4. Reduced risk of stroke
According to a study published in a journal, drinking green tea or coffee on a regular basis is associated with a reduced risk of stroke. Dr. Yoshiro Kokubo, lead author of the study, said, "This is the first large-scale study to investigate the effects of green tea and coffee on stroke risk. Adding green tea powder to your food every day can lower your risk of stroke, which can turn you into a small but positive lifestyle."
5. Prevention of Diabetes
For your information, research on the relationship between green tea and diabetes is inconsistent. One study found that people who drink green tea have a lower risk of developing type 2 diabetes than those who do not drink green tea, and other studies found that eating green tea and diabetes are completely unrelated.
6. Helps you lose weight
Green tea is small in overweight and obese adults, but it can promote weight loss. However, the study showed very little weight loss.
7. Improvement of skin diseases
A 2007 study concluded that green tea could be used as a new treatment for skin diseases such as eczema and dandruff. Researchers studied animals for inflammatory skin diseases, often characterized by dry, red-colored peeled skin due to inflammation and excessive skin cells. Animals treated with green tea were found to have slow growth of skin cells and were able to confirm the presence of genes that control the cell's life cycle.
8. Improvement of brain function
According to a study published in the journal Psychopharmacology, green tea can improve the brain's cognitive function, especially memory. The research team says green tea can be promising in the treatment of cognitive disorders related to neuropsychiatric disorders such as dementia.
side effects of green tea
Green tea may be better for breakfast or lunch. Caffeine and catechin can reduce the quality of sleep when drunk at night. Since green tea is very effective, but it can cause other side effects, let's drink dinner at a time when we avoid it through various green tea choices.
So we've talked about the green tea. You probably all knew that green tea is good for your body, but there are many people who do not know specifically what it does for your body. How about a cup of coffee and a cup of green tea rather than two cups of coffee a day?
