tea this The best anti cancer effect (image source: IC)
Yin Junfeng told reporters that some people like to drink light tea, some people like to drink thick tea, although the number of tea brews and different people's taste has a great relationship, but from the nutrient absorption, bagged tea is best only 1 times, and bulk tea is more than 3 times.
tea has the best anti cancer effect
he explained tea polyphenols, tea polyphenols, caffeine that can reduce blood sugar, caffeine that excexcited the central nervous system, and a variety of amino acids, vitamins and other nutrients. How much of these nutrients can be precipitated is very much related to the frequency of brewing. Generally speaking, the larger the particle size is, the slower the nutrient release rate. The smaller the particle is, the faster the precipitation will be.
compared with the bulk tea, the tea bag packed with tea in the process of processing and kneading fully destroys the leaf cells, and the shape of the particles is small. The nutrients in the tea will be precipitated from 80% to 90% after 3 to 5 minutes' first soaking, and after second times, about 10% of the remaining nutrients are almost all. It has been precipitated. Therefore, Yin Junfeng suggested that the best tea bags should be brewed once, not only in the absorption of nutrients, but also will not affect the taste and taste. Bulk tea because of the larger particles, the first time to soaking the best time, should be in 5 minutes or so, the nutrients will have 60% - 80% precipitation; after second times, there will be 80% - 90% of the nutrients precipitated; third times after the bubble, the leaching rate of nutrients will exceed 95%, and then soaking, already nothing. It's nutritious.
as for experts, it is pointed out that repeated brewing of tea will lead to leaching of harmful substances such as pesticides and heavy metals. Yin Junfeng pointed out that although there is some truth in this statement, there is no need to worry too much. At present, most of the pesticides used in China's tea production are very low in water solubility, according to 10 grams per person daily tea drink, even 1 mg / kg of residue of tea, only 0.0001 mg of pesticide, is one of the thousands of points per day allowed by the WHO. The leaching rate of heavy metal lead in tea leaves is relatively low. As long as regular tea is purchased, its content will not exceed the national standard.
