1. Do not use aluminum pots for cooking
Because during the cooking process, the temperature in the pot is high, and the high temperature or the friction between the metal spatula and the aluminum pot causes the aluminum pot to release aluminum. Long-term consumption of aluminum will cause our body to age rapidly, and even cause our metabolism to be disordered, resulting in poisoning. Therefore, we do not use aluminum pots for cooking. Not only cooking, but also try not to use aluminum tableware. The principle is similar to the previous one, the collision of iron and aluminum will release a lot of aluminum ions. In short, we'd better not use aluminum products.

2. It is best to use a wok for cooking
The iron pot conducts heat evenly and is free of pollution, and even the iron pot has been recognized by the World Health Organization. But nothing is perfect, and iron pans have drawbacks. Iron pans are prone to rust and cannot hold food at night. Moreover, do not use iron pots to cook soup to prevent the rust-free coating on the surface of the iron pot from being damaged. In addition, after brushing the pot, keep the pot dry to prevent the pot from rusting. Don't be afraid of rust, it can be removed with vinegar.
