What harm does tea dirt do to human body? How to remove tea dirt easily
Sihaiwang: there is a saying in our country that "if you drink tea and don't wash your cup, the king of hell will urge you.". Many people will encounter this situation. Generally, they use glass tea cups to drink tea. After drinking for a long time, there will be tea stains in the quilt. It is very harmful if the tea cups are not washed in time. But many people use a lot of methods to clean the dirty tea in the cup. If the dirty tea is not cleaned, what harm will it do to our body? What method can you use to clean the tea dirt easily?
Harm of tea dirt
Tea contains tea polyphenols, which are easy to oxidize and form tea dirt in contact with air and water, and adhere to the surface of teapot and teacup, especially the surface of rough pottery. Tea dirt contains arsenic, mercury, cadmium, lead and other harmful substances, which enter the human digestive system through the mouth. It is very easy to combine with protein, fatty acid, vitamin and other substances in the food, produce precipitation, hinder the absorption and digestion of nutrients in the small intestine, and can cause inflammation and even necrosis of kidney, liver, stomach and other organs. In particular, patients with ulcerative diseases often get worse after drinking tea dirt.
How to remove the dirt easily
1. Descaling method of potato and eggshell
First, pour half a cup of hot water into the heat preservation cup, cut the potatoes into small pieces, put them into the heat preservation cup, then tighten the cup cover and shake vigorously for two minutes. Open the water cup, pour out the water and diced potatoes, and then rinse them with clean water. You will find that the tea dirt attached to the wall of the cup is obviously less. Repeat this several times, and the tea dirt can be removed. If you don't have potatoes on hand, you can also replace them with broken egg shells. The same procedure is used.
2. Put a piece of lemon in the tea
Foreign researchers have found that one bag of British black tea at a time forms more tea dirt than two bags at a time, and five bags at a time does not form tea dirt, which is probably because the polyphenols in tea make the pH value of tea soup drop. Another patent achievement is to add a small amount of citric acid to the tea bag to adjust the taste and reduce the scale of tea. In addition, calcium ion is the key factor for the formation of tea scale, which promotes the oxidation of tea polyphenols and plays a role of cross-linking in the polymerization process. The harder the water is, the harder the underground water is, and the less the scale is. Tap water can boil the water for several minutes, in which calcium and magnesium will form salt carbonate alkali, reducing the formation of tea dirt.
3. Remove the tea dirt from the cup with orange peel
After eating oranges, everyone will discard the orange peel at will, but here, what Xiaobian wants to tell you is that wiping the tea cup with the orange peel can remove the tea dirt. For teapots, we can boil them with orange peel or citric acid with water, and clean the residue of teapots 2-3 times.
4. Scale removal method of salt and toothpaste
You can prepare a clean toothbrush, soak the bristles of the toothbrush, dip them in some salt, and then extend the toothbrush into the cup, and carefully brush the wall of the cup. The effect of descaling is very good. If you don't have salt on hand, you can use toothpaste instead. The bottom of the cup is the most difficult part to clean when descaling. You can dip a small soft cloth in some salt or toothpaste, wrap it on chopsticks, then extend chopsticks to the bottom of the cup, and stir them back and forth for several times.
