First, let's talk about the order of cup selection:
Glass cup>Ceramic cup>Stainless steel cup>Plastic cup
Glass Cup
The healthiest and safest, free from organic chemicals, with minimal leakage of harmful substances.
It is best to choose transparent glass cups, as most colored glass cups on the market are made with added pigments and may contain heavy metals.
Suggested selection of glass cup: 【 Heat resistant glass cup 】
Ceramic Cup
The colored glaze on ceramic water cups contains heavy metals such as lead, which may pose certain safety hazards.
So it's best to choose non colored glaze, which means the inner wall is white, which is the safest option.
Suggested choice for ceramic cups [high-temperature porcelain]
Stainless steel cup
Poor quality stainless steel can leach out metals such as chromium and manganese, which can have adverse effects on the human body.
Suggested choice for stainless steel cup: 【 Food grade 304/316 stainless steel material 】
Insulating cup: Remember not to pack:
× Fruit juice, carbonated beverages
If the insulation cup uses a high manganese low nickel steel inner liner, it cannot be filled with fruit juice or carbonated drinks, as the cup has poor corrosion resistance and is prone to heavy metal precipitation due to its acidity.
× milk
Filling milk in insulated cups can cause rapid microbial growth and even spoilage, which can cause gastrointestinal discomfort. Is it better to drink milk in a timely manner when it's hot
× tea
The insulated cup is high temperature and constant temperature, making tea easy to ferment. Aromatic oil will evaporate, and tannic acid and theophylline will be leached in large quantities. The nutritional value of tea will be greatly reduced, and tea will also become poor.
× traditional Chinese medicine
It is also inevitable that some people will use insulated cups to hold boiled traditional Chinese medicine. If this is the case, a large amount of acidic substances will react with the inner wall of the cup and dissolve into the soup. You may have drunk a "two in one"!
Plastic Cup
Plastic cups are also an unpopular type. Because plasticizers are often added to plastics, which contain some toxic chemicals, when using plastic cups to hold hot or boiled water, the toxic chemicals are easily diluted into the water. So, when choosing plastic cups, it is important to choose a water cup made of edible grade plastic that meets national standards.

As a water cup, it is best to purchase edible grade plastic, namely PP material (grade 05) or tritan material (grade 07)
