From the above table, we can see that the rapeseed oil, peanut oil and soybean oil that we often eat are more linoleic acid. But linoleic acid lowers high-density lipoprotein, a lipoprotein that is good for our body. According to the "Chinese residents' dietary nutrient reference intake", we should consume linoleic acid: linolenic acid = 4-6:1. According to the survey, we actually consume linoleic acid;

There are two types of oils that are good for health:

The first category is "high oleic acid" - olive oil, tea oil.

The second category is "high linolenic acid" --- linseed oil and perilla oil.

These two types of oil can lower blood lipids, soften blood vessels, prevent and cure some chronic diseases, and are also two types of edible oils that we lack.

What kind of oil is the healthiest! A little common sense about the life of cooking oil:

● For ordinary peanut oil and soybean oil, it is generally recommended to use cold oil in cold pan. After proper heating, start cooking. Try not to cook hot oil or fry. This will easily lead to oxidation of oil and affect the nutritional value of oil. .

● For oils with high levels of unsaturated fatty acids, such as tea oil and olive oil, it should not be used for cooking at all, because very slight heating will cause these oils to be oxidized and completely lose their proper health care function.

● The oil is replaced by food. For example, this time to buy is corn oil, then the next time you buy linseed oil. In short, it is a replacement between one class and another, rather than changing different varieties in the same class.

● The best method is “three-in-one package”, 1 part of linseed oil + 1 part of olive oil or tea oil + 1 part of vegetable oil or soybean oil or peanut oil or corn germ oil, which can be ratio of 1:1:1. Mixed to eat.

Some common problems with cooking oil

● Genetically modified edible oil. Nowadays, the edible oil bought in the supermarket, if not specifically marked as non-GMO, is mostly containing genetically modified raw materials. Looking at the ingredients list on the label, the words "Soybean is genetically modified soybean" and "Rapeseed" are written in very small fonts. It is genetically modified rapeseed." Even if we pay attention to not buying GM oil, but going to the restaurant outside, almost all of them will be genetically modified oil, because the price is cheap, some high-end catering may be better, but it is only better.

● Ditch oil. How to avoid buying waste oil, you should not say that you don't go to the grain and oil wholesale market or the farmer's market to buy oil. If you buy it in a large supermarket, the possibility of buying the waste oil is very small. Nowadays, the farmer's market is mixed, and many oil prices are obviously cheaper than supermarkets. There is a high possibility of being stupid.
