Is heating tin foil harmful to the human body?

Tin foil can often be seen in many people's kitchens, especially when baking in the oven. The advantage of tin foil is that it can preserve the flavor of the ingredients. When using tin foil for heating, you need to be aware of some precautions. If used improperly, toxic substances may be produced, which is harmful to the health of these people. In this regard, you must pay attention. Let us learn about it.

Is heating tin foil harmful to the human body?

1. Harmful. Tin foil contains a certain amount of aluminum and lead. When you eat a large amount of food wrapped in tin foil for a long time, it is very likely to cause nerve damage due to lead poisoning, often causing dizziness, nausea, and fatigue. Sometimes severe lead poisoning can also cause insomnia, headaches, etc. 2. The tin foil used for food packaging has strict requirements on the materials used. 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.

3. Since aluminum contains a large amount of lead, once the stability of the 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.

1. When using the oven at home, the chicken wings will produce oil when baking. At this time, we will use tin foil to bake the chicken wings, so that the oil will not flow into the oven. This is not only convenient but also easier to clean the dishes. 2. When baking, you can place food on the matte side of the tin foil. This will not only keep the food heated evenly, but also prevent the food from being burnt.

3. Since tinfoil has a good heat absorption function, if you wrap food that is not easy to cook in tinfoil and bake it, the food can be baked well and the cooking time can be shortened. 4. Sometimes when the meal is ready but not everyone is there yet, you can wrap the plate with tin foil, which can provide a good insulation effect. 5. When we perm our hair, we can also use tin foil to wrap our hair. This can speed up the perm process, and the tin foil will not damage the hair.
