Although there are many types of cups, filling water with some cups may not be healthy and safe. To ensure safety and health, stainless steel insulation cups are our first choice for healthy drinking.
The stainless steel material is used in the insulation cup, and the stainless steel that is truly qualified and does not have any adverse effects on the human body should be food-grade 304 stainless steel, and the relevant national standards have clearly pointed this out. After all, the water in the thermos cup is for us to drink. The higher the quality of the materials, the better the health of the human body.
Moreover, the iron element contained in stainless steel is also a trace element that people need to ingest every day. Stainless steel cups are alloy metal products. Depending on the use, the metal elements of this cup will be different. Common metal elements include iron and silicon. , Carbon, aluminum, etc. These elements cannot be provided to us by other cups. It can not only keep heat, but also keep cold, and it is very convenient to use in daily life.
But stainless steel mugs are not suitable for making tea and coffee.
Because tea leaves are soaked in warm water in a thermos cup for a long time, just like mild fried eggs, tea polyphenols, tannins and other substances contained in tea leaves will be leached in large quantities. The tea is rich in color and bitter. Also, because the water in the insulation cup will always maintain a high water temperature, the aroma oil in the tea will volatilize quickly, which also reduces the clear fragrance that the tea should have. The most serious point is that vitamin C and other nutrients contained in tea will be destroyed when the water temperature exceeds 80 ° C, losing the health care function that tea should have.
Glass insulation cup is healthy but not drop-proof
Glass is sintered from inorganic silicates, does not contain organic chemicals, and the glass is easy to clean, so glass is the safest. However, glass tea has the disadvantage of being easily broken, so it is not convenient to carry it with you.
Magnetized insulated cup
From the point of view of medical care, the magnetic insulation cup has a good health effect. Magnetized thermos is a drinking utensil that achieves health care through non-medicinal means. The physical properties of magnetized water are magnetized, its solubility is strong, it can soften, dissolve sediment in blood vessels, and prevent cardiovascular diseases such as arteriosclerosis. The various solids have a dissolving or differentiating effect, so that lithiasis can be relieved, the dissolving and oxidizing capacity of magnetized water is improved, and the oxygen content is higher than that of ordinary water, which can promote the metabolism of the human body.
Medical reports at home and abroad have also stated that magnetized water is indeed beneficial to human health, but not all magnetized water is beneficial to the human body. Only the magnetized water of the negative electrode can improve the physiological function of the human body and play a role in health care, while the magnetized water of the positive electrode should not be drunk.
As we have seen on the market now, many so-called magnetized insulation cups are actually just ordinary magnets. Therefore, consumers should carefully discriminate when choosing a magnetized insulated mug, and choose a single-stage magnetized plate (negative pole) as the raw material.
In summary, the stainless steel thermos is the most suitable for drinking water, but it should not be used for making tea, and pay attention to buy stainless steel thermos from regular channels to prevent iron cups.
