First of all, the rust of the iron pot may adhere to the bottom of the pot, causing the dishes to lose their taste, and there may be undetectable rust chips mixed into the food and eaten.

Secondly, rust contains metal elements such as iron and manganese, and these metal ions will accumulate in the body after being ingested by the human body, which may affect health. For example, excessive intake of iron ions will affect the body's absorption and utilization of other minerals, interfere with metabolism and produce unnecessary free radicals. When the intake of metal ions exceeds the human body's needs, it may also form toxic substances in the body, causing headaches, dizziness, fatigue, anxiety and other symptoms.

In addition, the rusty pot surface may be parasitized with bacteria, which will cause digestive diseases such as food poisoning and diarrhea, and even cause more serious health problems.

Therefore, in order to protect health, rusty or oxidized pots should be avoided in daily cooking, rust should be removed before using iron pots, and attention should be paid to maintaining iron pots to avoid rust. If the body is abnormal, you should go to the hospital for examination and treatment under the guidance of a doctor.
