Water is the source of life, want to make our body healthier, the first thing is to drink more water. Drinking water can not be separated from the cup, choosing a good cup is also very important. So in the end what type of cup is more harmless?

1. Metal cups

Metal cups such as stainless steel mugs, etc., belong to alloy products, are fall-resistant and durable, and the price is not expensive.

But do you know? Stainless steel cups' improper use can also be harmful to health!

We can usually use stainless steel cups to hold plain water, but like juice, coffee, carbonated drinks, and other acidic drinks should try to avoid using stainless steel cups, because it is easy to precipitate heavy metal substances harmful to health.

In addition, do not use strong oxidizing soda, bleach, etc. to clean stainless steel cups, because these substances are also prone to chemical reactions with stainless steel.

2. Plastic cups

From ordinary drinking cups to disposable cups used to entertain guests, plastic cups are convenient and cheap, common at home. But a long time to use plastic cups drinking water is not safe!

Plastic is a polymer chemical material, often containing toxic chemicals such as polypropylene.

Most of the polymer chemical materials encounter hot water is easy to precipitate these molecules into the water, so try to avoid using plastic cups to fill boiling water.

In addition, the internal microstructure of plastic has a lot of pores, easy to hide dirt. Cleaning is not clean, it is easy to breed bacteria.

So not all plastic cups are suitable for water cups, when buying and selling you must recognize the cup with a qualified logo.

3. Ceramic cups

Ceramic mugs daily fewer people use, but relatively safe.

In the production of tableware and mugs of ceramic for food grade, the requirements of the content of heavy metals are more stringent.

However, ceramic mugs with some special patterns, patterns, and colors can also be a safety hazard, try not to buy mugs with special patterns on the inside of the ceramic mug for high value!

4. Glass cups

Glass cups are beautiful and fragile, but being used to drink water is safer.

It is produced at high temperatures, many harmful substances will be decomposed at high temperatures, and heavy metals will be removed by oxidation, while the process will not have harmful ingredients added.

In addition, the glass is more transparent, but also easy to clean.

Then we will have questions, that beautiful colored glass is the same health?

The glass itself does not carry color, except for some colored glass formed during production because of natural minerals.

Most of the colored glass is added in the process of processing and production of pigments, and generally, these pigments contain heavy metals that are harmful to humans, so it is not recommended to use colored glass cups.
