Long-term consumption of foods containing large amounts of aluminum and aluminum compounds will damage the normal proportion of calcium and phosphorus in the human body, affect the growth, development and metabolism of human bones and teeth, as well as affect the activity of certain digestive enzymes and weaken the digestive function of the stomach.Therefore, aluminum pot bogey long dish.It's also best not to use an aluminum pan to fry vegetables or to cook soup.

Cadmium poisoning can cause lung and bone damage.Lead poisoning can cause anemia, neurasthenia, bone marrow hyperplasia and other diseases.So for color porcelain.The tableware such as coloured pottery, especially the tableware that the inside wall has coloured glaze design must not be used.

6.Avoid stainless steel or iron pot decoction of Chinese traditional medicine
