Recently, many media outlets reported on the incident of a 16 year old girl drinking green tea leading to acute hepatitis. Green tea is considered a very healthy beverage and can cause acute hepatitis, which is really scary.
In the report, it was mentioned that the 16-year-old girl developed symptoms of acute hepatitis, and through self reporting and examination, no other factors leading to hepatitis were found. After detailed inquiry by the doctor, it was learned that the girl had been using online green tea products to lose weight for the previous three months. The doctor suspected that the product was related to acute hepatitis, and after the girl stopped drinking the tea, her liver indicators quickly returned to normal. The article did not specify what the green tea product she purchased online was, but from the fact that most of the ingredients she described were written in Chinese, it can be inferred that he obtained a non pure product and should have used a green tea weight loss product containing multiple ingredients. And our company can provide products with high purity, with microbiological and heavy metal indicators above international standards.
Green tea extract is not the first case of liver injury
Green tea is a very healthy beverage, almost sugar free, fat free, calorie free, and rich in natural antioxidants. Green tea extract, on the other hand, is a product obtained through solvent extraction, with various components concentrated. Clinical studies have shown that drinking 1.6 grams of green tea extract at once is not a problem, but using green tea extract more often can have subtle changes in the body.
Researchers have found that drinking green tea will not harm the liver. Epidemiological investigation shows that regular use of green tea products can help reduce transaminase, but green tea extracts may have a great impact on the detoxification function of the liver. In a clinical study on women taking green tea extract after menopause, 6.7% of the users showed an increase in transaminase, while only 0.7% of the control group.
A website in the United States collected some cases of liver injury caused by taking green tea extract and pointed out that the number of cases mentioned in the literature exceeded 50. Although this is not significant compared to the total number of people taking green tea extract, and based on the summary of cases, it can be concluded that the damage to liver function caused by green tea extract usually occurs within 3 months of taking it, and disappears quickly after stopping taking it. We can infer that in cases of "green tea liver injury", the majority are caused by the intake of green tea extract or concentrate, and it is rarely caused by direct consumption of green tea, and many are due to short-term reasons, Concentrated use exceeds the purification ability of the body's liver.
The possible causes of liver injury were explored in the New England Journal of Medicine Case Report. The author believes that the substances added to the extract during processing may cause hepatotoxicity. In addition, if the pesticide residues in tea exceed the standard or are stored improperly, it will affect the final production (many factories do not pay attention to this item), which may lead to an increase in product toxicity. In addition, catechins in green tea extracts may also cause liver damage
In fact, the core component of green tea extract is catechins. Catechin is a type of tea polyphenol that is abundant in green tea. In 2018, the European Food Safety Agency released an expert report on catechins, which believed that the daily intake of more than 800 mg of catechins might lead to an increase in transaminase.
800 milligrams of catechins are equivalent to more than 10 grams of green tea being completely brewed out. For ordinary tea drinkers, it is not possible to drink this amount. However, if you take green tea extract, it will be uncontrolled and it is easy to overdo.
In fact, as long as you enjoy drinking green tea, you can drink it with peace of mind. If we consider the conclusion that the intake of catechin more than 800 mg may increase transaminase, we can control the daily consumption of green tea to 10 grams, and there is no need to tangle. If you need to drink more tea, you can also drink some other types of tea, such as black tea, white tea, oolong tea, black tea, etc. In these tea types, catechins are oxidized into other forms, such as theaflavins, thearubigins, etc.
