Watch out for the dissolution of heavy metals when drinking coffee in metal cups

It is safe to drink clean water, and the safety of the cup is equally important. Yesterday, Feng Xiaoxia, a professor in the Department of Gastroenterology of the second affiliated Hospital of heavy Medical College, told Yousheng that the choice and use of cups are very knowledgeable, and it is easy to endanger your health if you are not careful.

Customers don't know the material and only look at the style.

Yesterday, the reporter came to some supermarkets in our city and saw that there were all kinds of cups of various materials, such as ceramic, glass, enamel, plastic, stainless steel and so on, but the reporter randomly interviewed several citizens who were buying cups. They didn't pay attention to the material when they bought the cup, they just picked the good-looking ones to buy. "in fact, the cups used to drink water, glasses, enamel cups and ceramic cups are the healthiest and most environmentally friendly." Feng Xiaoxia, a professor in the Department of Gastroenterology of the second affiliated Hospital of the heavy Medical University, said that the glass does not contain organic chemicals. When drinking water or other drinks from the glass, you do not have to worry that the chemicals will be drunk into your belly and are easy to clean. It is a safe cup. In addition, the enamel cup is made after high temperature enameling, does not contain lead and other harmful substances, can rest assured to use.

Plastic mouth cup is limited in heat resistance and used with caution.

"plastic cups have the most hidden dangers." Professor Feng Xiaoxia revealed that when plastic cups are filled with boiled water or drinks with high acidity and alkalinity, lead and other toxic heavy metal elements in pigments are easily dissolved in the liquid, and people drink the liquid with chemicals, which will do harm to the liver and kidneys. Many plastics have plasticizers and contain some toxic chemicals. Boiled water is filled with plastic cups, and toxic substances are easily diluted into the water. Therefore, when choosing and buying plastic cups, you must choose water cups made of edible-grade plastics that meet national standards.

Do not use a metal cup to hold coffee juice

Feng Xiaoxia also pointed out that don't drink coffee from metal cups. Metal cups, such as stainless steel and enamel cups, are usually stable, but they may dissolve in an acidic environment, so it is not safe to drink acidic drinks such as coffee and orange juice.

Many people like colorful cups and should be careful to contain heavy metals. When the cup is filled with boiled water or drinks with high acidity and alkalinity, the toxic heavy metal elements such as lead in these pigments are easy to dissolve, causing harm to the human body.
