Does Chinese green tea have oxalates?
Yes, green tea contains oxalic acid. However, it will not have a negative effect on the body when consumed in moderation.
1. The chemical composition of green tea and its effects
Green tea is a non-fermented tea that contains a variety of chemical components, such as catechins, caffeine, and tea polyphenols. These components help reduce blood cholesterol, promote blood circulation, and improve immunity.
2. Oxalic acid in green tea
Oxalic acid is an organic acid also known as oxalic acid. It is a toxic substance that is commonly found in plants, water and soil. Unlike other organic acids, oxalic acid can combine with calcium in the human body to form calcium oxalate, which is difficult to digest and harmful to the body.
Studies have shown that green tea contains oxalic acid. However, the amount of oxalic acid is relatively low, and other ingredients in green tea can neutralize the effects of oxalic acid and reduce its harm to the body.
Does Lipton green tea cause kidney stones
Conclusion: Not necessarily
True Image Analysis:
Drinking tea does not necessarily cause kidney stones. Long-term heavy consumption of tea, or strong tea, may increase the chance of developing kidney stones, but it does not necessarily lead to the formation of kidney stones.
The reason for the rumor that “drinking tea causes kidney stones” may be because tea contains oxalic acid. After entering the human body, oxalic acid reacts with calcium ions to form calcium oxalate, which gradually precipitates to form solid stones. This theory seems plausible, but it is actually very arbitrary.
After the human body ingests oxalic acid, most of it is not absorbed by the small intestine and is already combined with calcium from food to form a precipitate that is excreted with the stool. The amount of oxalic acid that can be absorbed by the small intestine and enter the bloodstream to form calcium oxalate in the kidneys is very small. Only when the concentration of calcium oxalate is too high will crystals precipitate, and when there are enough crystals, will stones form. Moreover, citric acid in the urine can inhibit calcium oxalate crystallization. Therefore, it is actually very difficult for oxalic acid in tea to.
