Sometimes, because they are too interested in drinking or drinking how much new amounts, we forget that water containers are equally important.Regardless of what kind of drink, in the cup of bad material, toxic, each drink is once "poisoned".
Do not save the wrong way, ignorance or follow the beauty of the outside but trade off your health and life when using the 4 types of cups below:
1. Porcelain cup
Dish or fake cups are popular with many modern families.Because it is much cheaper than real porcelain but lightweight, beautiful and less broken.However, using this cup of water from day to day is no different from being "poisoned" chronic.
The fake cup of porcelain is beautiful but has many potential health risks (Artwork)
They are usually made from very poor heat -resistant melamine.Therefore, not only the function when holding hot drinks is reduced but also easy to produce toxins.Specifically, toxic substances such as melamine and formaldehyde.The body absorbed for a long time can cause poisoning, liver impairment and cancer.The World Health Organization has ranked formaldehyde as toxic chemicals for human health, which is part of the level 1 cancer group.
Poor quality melamine cups are even more dangerous, they use urea-formaldehyde plastic instead of melamine.This plastic is more toxic and has a higher formaldehyde release speed.They can also contain many impurities and heavy metals that are not friendly to human health.
2. Disposable paper cup
This cup is very convenient, seems to protect the environment but not so.Therefore, you should not use it often.
According to research from the Indian Institute of Technology, the use of hot drinks in paper cups increases the risk of swallowing pollutants such as small plastic particles, harmful ions, heavy metals ...Forming reproductive defects, cancer, even neurological disorders.
In particular, some paper cup manufacturers also add a large number of fluorescent whitening agents to make the cup look whiter.It is this type of fluorescent substance when penetrating the body that can cause cell mutations and a potential factor causing cancer.The disposable paper cup also does not protect the environment as many people think.It contains many chemicals, micro -plastic and difficult to decompose as the plastic cup.
Although convenient, but should not use paper cup once too often (Artwork)
3. Cheap stainless steel cup
Despite keeping the heat for a long time, hard to break, easy to clean, drinking water from stainless steel cup also has many health risks.Especially with cheap stainless steel cups, sold floating without brand.
Due to specific materials, stainless steel cups usually have high cost.With cheap stainless steel cups will be mixed with many impurities, containing many heavy metals.In the process of containing drinks, especially hot dishes will be faded and absorbed into the human body.These include lead, chromium, manganese, cadmium ... too much accumulation will cause dangerous diseases.
Should choose the types of cups and tools for stainless steel good quality, tested (Artwork)
Even with good stainless steel cup, it is not a great choice to store highly acidic drinks such as coffee, tomatoes, orange juice, lemon, carbonated soft drinks ... because stainless steel is an alloy product,Can dissolve in an acidic environment, so it can cause heavy metal precipitate in the composition of the cup and harm health.Also adversely affect the taste of drinks.Naturally, the cheaper stainless steel cup, the poorer the quality, the more dangerous.
In addition, when using stainless steel cups should not use strong detergents during cleaning because these substances are also more likely to react with stainless steel.Also should not use iron brush because it is easy to cause scratches, stopping the substance harmful.
4. Inner enamel cup
The enamel cup is actually a metal cup covered with a porcelain layer.You may be attracted to the beauty while the price is cheap, but do not drink water contained with a cup with enamel layer inside the cup.
Because of the low heating temperature, the porcelain form is not stable enough.Therefore, its durability when looking at the naked eye is high but the actual function is low.The enamel coating inside is in contact with drinks, temperatures, and scrubs that are easy to wear and wear, reducing heat resistance.It will even quickly reveal the metal ingredients and stop in the drink.
The enamel cup usually has a core made of metal, which will be worn out for a long time.
Not to mention the metal used for enameled cups is often of poor quality, contains many impurities because it is safe to have a porcelain layer covering.When enameled cups are exposed to beverages (especially acidic foods), toxic metals will easily leak out and react with each other.Since then turn our drinks into a "poison" silently accumulating and harming the body.
