Cooking oil precautions
High-temperature frying many people like to stir-fry at high temperatures, accustomed to wait until the oil in the pan smoke before frying, this practice is unscientific. High-temperature oil will not only destroy the nutrients of food, but also produce some peroxide and carcinogenic substances. It is recommended to heat the pan first, then pour the oil, then you can fry the food, do not have to wait until the oil smoke.
Long-term only eat a single variety of oil now, the average family is still difficult to do what vegetables fried with what oil, but we recommend that it is best to alternate several kinds of oil with food, or a period of time with a kind of oil, the next period of time to change another kind of oil, because there is rarely an oil can solve all the oil needs of the problem.
