Is tin foil toxic

Every time summer comes, barbecue grills will be lit outside. Eating barbecue is a very enjoyable thing, but some people say that eating too much barbecue is bad for the body. Because when eating barbecue, most people use tin foil to make barbecue. Edible tin foil is non-toxic, but open flame grilling may cause chronic lead poisoning. Whether liposuction is toxic depends on the quality of the tin foil and the material inside it.

Are things baked in tin foil toxic?

Using tin foil in a microwave oven to bake non-toxic open flames can cause chronic lead poisoning

Many of the tin foils sold on the market today are actually aluminum foil. The two sides of the paper are made of plastic or special coatings, and the middle layer is aluminum. It is fine if it is only used to package food, but if it is used to wrap food and then roasted directly, it will cause direct harm to the human body.

When food is processed by frying, grilling, smoking, etc., it is easy to produce carcinogens such as benzopyrene and dioxins, so it is indeed not advisable to eat too much of it. It has not yet been confirmed whether wrapping food in tin foil before baking can prevent the production of carcinogens. But regardless of whether it has the function of isolating carcinogens, tinfoil can easily cause heavy metal pollution.

Since aluminum contains a large amount of lead, once the stability of aluminum foil does not meet the standard or comes into direct contact with open flames, lead is likely to dissolve. If people often eat this contaminated food, it will affect the normal functioning of the human nervous system, hematopoietic system, cardiovascular system, and digestive system.

Among them, the nervous system is most susceptible to damage by lead, which can lead to symptoms such as fatigue, insomnia, irritability, headache and hyperactivity. Lead can also inhibit the synthesis of hemoglobin and antagonize elements such as iron, zinc, and calcium, inducing anemia, which worsens with the increase of lead poisoning. Although baking food with tin foil will not cause poisoning to the human body, it will have an impact on the human body if it is baked with an open flame.

Is tin harmful to the human body?

Tin is not harmful to the human body, but metallic lead is harmful to the human body. In ancient times, people used tin sheets to purify well water.

Modern people often add ice cubes to beer or wine to get a refreshing cool feeling. Tinware is cool in nature and has good heat dissipation effects, so it can immediately lower the temperature of the wine, making it clear and refreshing when you drink it.

Tin is a valuable metal second only to gold and silver, and it has the ability to absorb impure substances. In the past, in places with poor water quality, people would place tin plates at the bottom of the well to purify the water. Because tin easily reacts with arsenous acid, cyanic acid, etc., it also has a certain degree of toxicity.

Tin does not have any metallic smell, and pure tin products are not harmful to the human body. Since tin can absorb impure substances, water in a vase made of tin will not easily become turbid and can keep the flowers fresh for a long time.

Tin itself is processed. The biscuits we usually eat are wrapped in tinfoil, which is a kind of paper made of processed trace elements. The packaging tubes of the tea we usually drink are made of tin iron, so you can rest assured that it will not harm your body when you inhale it.
