First of all, there are two kinds of oils that are good for health.
The first "high oleic acid"-olive oil and tea oil.
The second kind of "high linolenic acid"-linseed oil and perilla oil.
These two oils can reduce blood fat, soften blood vessels and prevent some chronic diseases. They are also two kinds of edible oils that we lack.
Second, how to eat oil is the healthiest!
1. For common peanut oil and soybean oil, it is generally recommended to cool the oil with a cold pan and heat it properly before stir-frying. Try not to heat or fry oil in a hot pot, which will easily lead to oil oxidation and affect the nutritional value of oil.
2. Oils with high unsaturated fatty acids such as tea oil and olive oil should not be used for cooking at all, because very slight heating will lead to oxidation of these oils and completely lose their due health care functions.
3. eat oil instead. For example, I bought corn oil this time, so I will buy linseed oil next time. In short, it is a substitution between one category and another, not different varieties in the same category.
4. The best way is "three-in-one set meal", that is, 1 serving flaxseed oil+1 serving olive oil or tea oil+1 serving vegetable oil or soybean oil or peanut oil or corn germ oil, which can be mixed and eaten according to the ratio of 1: 1.
