Usually we all like to choose beautiful tableware, because this can increase the fun of eating, but some tableware contains carcinogenic substances, we must be careful, alert to the carcinogenic substances in tableware.
Ceramic tableware is the least toxic. The glaze in many colored ceramics contains lead, which is toxic and can damage health if ingested in excess. The coloured glaze on the surface of ceramic tableware may become a health killer. Color glaze contains lead, mercury, radium, cadmium, etc., these are harmful to the body elements. We’d better use boiling water to boil tableware for 5 minutes, or soak in vinegar for 2 to 3 minutes to dissolve the toxic substances contained in tableware after you get the new tableware.
Plastic has strong water resistance, which contains vinyl chloride carcinogens, long-term use will induce cancer. In addition, the surface patterns of plastic tableware contain metal elements such as lead and cadmium, which can cause harm to the human body. There is a protective film on the surface of plastic products. Once the film is scratched by hard devices, harmful substances will be released. We should choose no decorative pattern, colorless and tasteless, smooth surface, feel solid plastic tableware.
Stainless Steel tableware
Stainless steel contains trace metals that can also be dangerous if consumed in excess, such as nickel, which is a carcinogen. Stainless steel tableware is printed with “13-0”, “18-0”, “18-8” three codes, the number in front of the bar represents the amount of chromium, chromium is not easy to rust the product material; The latter number represents the nickel content, and the higher the nickel content, the better the corrosion resistance. In order to prevent nickel, chromium and other heavy metals from harming human body, the country has relevant standards for its dissolution amount, and regular products can be used at ease. But stainless steel tableware can not be used to put strong acid or alkaline food for a long time, because this may lead to chromium, nickel and other metal elements dissolved; Once found stainless steel tableware deformation or surface damage, should be replaced in time.
Bamboo and wooden tableware
Bamboo and wood itself is not toxic. But, the bamboo and wood with besmear paints is harmful to human body, because the nitro in paint, once enters human body, may combine with other materials to become carcinogen nitrosamine.
