Chopsticks can be divided into traditional wooden chopsticks, bamboo chopsticks, plastic chopsticks, metal chopsticks, Ivory chopsticks, and ceramic chopsticks according to the material they are made of.
(1) Traditional wooden chopsticks: Natural wooden chopsticks are non-toxic and harmless, but in many cases, the outer layer of wooden chopsticks will be painted. The paint contains carcinogens such as heavy metal lead and organic solvent benzene. With the use of wear and tear, the paint will fall off and enter the human body with food, endangering human health.
(2) Bamboo chopsticks: Bamboo chopsticks are non-toxic and harmless, very environmentally friendly, not easy to clean, and water absorption, adsorption is strong, often there will be detergent residues, easy to be contaminated by pathogenic microorganisms, so we should pay attention to regular disinfection, keep clean.
(3) Plastic chopsticks: crisp texture, easy to deform and melt after heating, resulting in harmful substances to the human body.
(4) Metal chopsticks: The use of silver, stainless steel, and other metal chopsticks is too heavy, feels bad, and thermal conductivity is strong, eating overheated food, easy to burn the mouth.
Using inferior metal chopsticks may cause the harm of heavy metals to human health.
Titanium chopsticks are non-toxic, harmless and easy to clean, and lighter than stainless steel and silver chopsticks.
(5) Ivory chopsticks: Bone chopsticks are good in texture, but easy to change color, and the price is relatively expensive.
