Let's talk about iron pots first. The advantages of iron pot are low price, fast heat conduction, and more dishes can be fried at one time, which is suitable for families with large population. And frying in an iron pan will increase the iron content in the dish. The disadvantage is that cooking in an iron pan requires more oil to avoid burning the pan, and there is more oil smoke in high-temperature cooking. In addition, although there is a little iron in wok cooking, it belongs to the metal pollution of wok. This kind of iron is non-heme iron, and the absorption rate of human body is very low. Anemia patients simply can't count on cooking in an iron pot to supplement iron. Therefore, from a health point of view, wok cooking is easy to use more oil, which is not the best choice for healthy cooking.
Besides, non-stick pan. The advantages of non-stick pan are that the bottom of the pan is heated evenly, less cooking oil and less oil smoke, and cooking will not paste the pan. The disadvantage is that it is more expensive, and the coating in the pot is easy to fall off after a long time. Some people worry that the coating on the non-stick pan will release harmful substances at high temperature. In fact, the temperature of normal cooking methods such as cooking will not let the non-stick coating release harmful substances. Even if the coating falls off, the human body will not absorb and digest the polymer coating. From the health point of view, non-stick pan cooking is the best choice for healthy cooking with less oil and smoke.
There are stainless steel pot in the market now. Besides iron, the main materials of stainless steel are manganese and chromium. Its advantages are corrosion resistance and acid and alkali resistance. When cooking, stir-fry and stew slowly with a small amount of oil, which is not easy to paste the pot. The disadvantage is that it is expensive, and it is easy to burn the pot when cooking in a big fire or fast fire. Some people worry that manganese in stainless steel pot will cause dementia. In fact, manganese is a highly insoluble metal element. During normal cooking, manganese won't get into food without scraping the wall with a spatula. From the health point of view, stainless steel pot is also a good choice for healthy cooking.
Finally, we come to the conclusion. Non-stick pan is the best choice for cooking, with less oil and even heating. Stainless steel pot is the second choice, followed by iron pots.
