Green tea is not fermented, so the most original substances in the fresh leaves are retained to the greatest extent. Among them, tea polyphenols, amino acids, vitamins, and many other nutrients are kept in large quantities, providing the basis for Green tea’s health benefits. Let us find out why it’s so healthy!
Fat Loss and Cholesterol-lowering
Green tea contains a combination of polyphenols, amino acids, and vitamins that can help reduce and burn excess blood fat, especially tea polyphenols and vitamin C, which are the key to reducing fat, aiding digestion, and reducing fat and weight loss.
In addition, it is also beneficial to improve the good cholesterol in the body. Japanese research found that after three months of consuming 500mg of Catechin daily, although there was no change in total cholesterol concentration, there was a significant increase in HDL cholesterol concentration.
Anti-aging
Whether oolong tea, black tea, or green tea, there are strong antioxidant substances EGCG in tea leaves, which can neutralize free radicals in the body and help slow down aging. Studies have shown that EGCG has a ten times stronger antioxidant effect than vitamin E and two times higher antioxidant level than red wine, making it a critical substance to help slow down aging.
Increase Bone Density
A Texas Tech University Health Science Center study showed that menopausal women who took 500 mg of green tea polyphenol capsules (about 4-6 cups of tea) a day for six months could promote bone reconstruction and delay bone loss.
Radical Scavenging
A study published in the British medical journal “Nanomedicine” pointed out that the “EGCG” substance in green tea has a significant effect on skin cancer. Whether green tea, black tea, or oolong tea, the high amount of polyphenols in tea can scavenge free radicals and inhibit undesirable cells.
Tooth Decay Prevention
Tea contains fluoride, which can inhibit bacteria, and catechins can also inhibit streptococci and other bacteria, which can help reduce bacteria adhering to teeth and staying in the mouth, thus reducing the chance of tooth decay. It is also clinically proven that catechins can significantly reduce the formation of dental film but have no effect on other microorganisms in the mouth.
Anti-radiation and UV Resistant
Modern people use computers and mobile phones daily, and their radiation exposure is higher than in the past. In addition to being rich in vitamin C, tea can also resist radiation damage caused by UVB; rich vitamin A can help resist computer radiation to the eyes and protect eyesight.
Refresh Your Mind
The polyphenols and catechins in green tea can help reduce the degradation of brain neurotransmitters such as dopamine and adrenaline, making people recover quickly, especially when they wake up in the morning. Green tea can effectively refresh the mind, and the caffeine content in green tea is less than that of coffee, which is less irritating to the human body.
Weight Loss and Disease Prevention
Green tea contains a certain amount of caffeine. Coexisting with tea polyphenols can inhibit the effect of caffeine in the stomach to stimulate gastric acid secretion. Moreover, the aromatic compounds in green tea can also help degrade fat and prevent fat from accumulating in the body.
However, t should be mentioned that it is better not to drink green tea during menstruation. Studies have shown that in addition to the average loss of iron in the human body, women will lose an additional 18-21mg of iron each menstrual period.
Green tea contains more tannic acid, which will combine with iron molecules in the food to form a large amount of sediment, which hinders the intestinal tract. The mucous membrane can absorb iron molecules, and the thicker the green tea, the greater the hindering effect on iron absorption.
Although green tea is generally considered safe and healthy, there are a few reasons to avoid it. Green tea retains more fresh natural substances, such as tea polyphenols, caffeine, and chlorophyll, which stimulate the gastrointestinal tract. This is why some people feel uncomfortable after drinking green tea. It is best not to drink green tea for those with gastrointestinal diseases.
Besides, if you are allergic or sensitive to caffeine may need to limit green tea consumption. Also, the caffeine and tannins in tea can reduce iron absorption, especially plant-based iron. Therefore, those diagnosed with or at risk for anemia may need to reduce their tea intake.
