Just like bowls and chopsticks, cups are indispensable items in the family. Just for decoration, just to receive guests and more importantly, to hold drinking water.
However, on the market today, there are many types of cups with different designs and materials. It is also worth noting which type of cup is really safe. Because if you choose poor quality cup products, it is possible that chemicals will be contaminated with drinking water, and then directly harm health.
Going to the market to buy cups, there are 3 types that experts recommend to limit or not use.
1. Disposable paper cups
Disposable paper cups look very hygienic and convenient. However, they are not safe for the environment and health.
The team of researchers from the Indian Institute of Technology, Kharagpur said that sipping hot drinks from paper cups can lead to the ingestion of contaminants such as tiny plastic particles, harmful ions, metals, and other contaminants. severe… That increases the risk of reproductive defects, cancer and even neurological disorders.
To get to this conclusion, the scientists tested pouring hot ultrapure water into a 100ml paper cup. After 15 minutes, they added a special drug to detect and quantify plastic particles in the collected water sample. Scientists have discovered about 25,000 small plastic particles in hot water. This includes heavy metals such as lead, chromium, cadmium and arsenic…
In addition, some paper cup manufacturers have added large amounts of fluorescent whiteners to make the cups appear whiter. It is this type of fluorescent substance that can cause cells to mutate and become a potential carcinogen if it enters the human body.
2. Colorful mugs
Colorful drinks cups are often very eye-catching, but the reality is that the more colorful the utensils, the higher the risk of harm to health.
The color covered on cups or dishes may be a paint, during use it can be contaminated into drinking water, causing danger to users.
These paints may contain heavy metal elements such as lead. Lead poisoning will cause weight loss, nausea, abdominal pain, increased risk of high blood pressure, in the long run will cause kidney and brain diseases. Therefore, when choosing cups, we should not buy cups with too colorful colors.
3. Plastic cup
Plastic cups are also an unwelcome cup for home use. Because plastic is often mixed with plasticizers, containing harmful chemicals. These chemicals can be easily diluted into water when hot or boiling water is used.
The US and Canada banned the use of single-use plastic cups because Styrene was found to be harmful to users’ health, especially possibly causing cancer.
At the same time, the microstructure inside the plastic has a lot of voids, which is an ideal reservoir for dirt and bacteria. Therefore, when buying plastic cups, be sure to choose one that is made of food-grade plastic that meets national standards.
When going to the market, what kind of cup is the safest to take home?
Glass mugs and colorless glazed porcelain mugs are the two safest cups to use.
The glass beaker does not contain organic chemicals during the firing process. Moreover, the glass surface is smooth and easy to clean. Bacteria and dirt do not easily breed on the sides of the cup, so drinking from a glass cup is the best and safest for health.
As for the colorless glazed porcelain cup, it is both safe in terms of material, resistant to high temperatures, but also has a relatively good insulation effect, used to drink hot water or drink tea is a good choice.
In addition, you can also use enameled cups, stainless steel cups. However, it is not recommended to store acidic drugs such as orange and lemon juice for a long time because it can decontaminate the water with yeast; or precipitation of heavy metals.
When cleaning stainless steel cups, do not use soda because they have strong oxidizing properties, bleaching agents, etc. These substances are also easy to cause chemical reactions with stainless steel.
