Soybean oil, daily consumption is no problem. The "Compendium of Materia Medica" mentions that "smearing scabies and relieving hair and ajacil" has the effect of moisturizing the intestines and laxative, repelling insects and detoxifying. At the same time, it is rich in saturated and unsaturated fatty acids, especially its high content of linoleic acid, which can reduce cholesterol content and has important functions. If the elderly are deficient in linoleic acid, the probability of cardiovascular disease may increase. Soybean oil is a very good oil for daily use at home.
Peanut oil, suitable for use in middle-aged and elderly people. According to the China Medical Publishing House, "How to Eat Oil is Healthier: Demystifying Cooking Oil in the Kitchen". Ingredients such as resveratrol in peanut oil can slow the aggregation of platelets and prevent arteriosclerosis and thrombosis.

Peanut oil is loved by everyone because of its wide planting area and the unique aroma of stir-fry. It is a variety of oil commonly used in everyone's home. The fatty acid composition of peanut oil is relatively good and is more easily absorbed by the body. It also contains a large amount of linoleic acid, which can reduce the body's cholesterol content. However, peanut oil has a low content of unsaturated fatty acids, and it is recommended to supplement with unsaturated fatty acids such as rapeseed oil in moderation.
Note that normal peanut oil is transparent and clear in the summer, and thickens and thickens in the winter. This is the reason why peanut oil contains saturated fatty acids, do not think that peanut oil discoloration is deterioration, this is a normal phenomenon. See if that's the case with your peanut oil!
Olive oil, everyone should have a bottle. Most household oils are soybean or peanut oil. They are good, but they do not contain enough monounsaturated fatty acids. The monounsaturated fatty acids of olive oil are the highest among vegetable oils, reaching up to 73.7 grams per 100 grams. Therefore, those who often eat soybean oil at home can buy a bottle and put it at home, changing the taste from time to time. Olive oil is known as the "queen of vegetable oil". This cooking oil can be consumed without heating and is highly regarded by nutritionists. Olive oil can also slow down the hardening of arteries, suitable for patients with high blood pressure and heart disease.
How to buy oil is also a science.
The first is not to buy gutter oil. Gutter oil is made up of a variety of inferior waste oils, and some unscrupulous merchants treat these waste oils as normal oils for profit. Although its composition is the same as most edible oils, it contains a large number of heavy metals with microorganisms exceeding the standard because of its unhygienic source or production conditions. Therefore, the first step in buying edible oil is to buy from reliable merchants, or buy large brands, and the quality can be guaranteed. Don't covet cheapness, but harm the body.
Eat as much as you want to buy. The oil purchased in the supermarket is basically the larger the barrel, the more cost-effective it is. Families with more people can buy large barrels of oil in moderation, but families with less oil are recommended to buy small barrels. The vat may deteriorate because it has not been eaten for a long time because it has been unsealed, and when your oil has a harrah's taste, then don't eat it again.
Hybrid purchases. Nutritionists point out that various edible oils should be consumed alternately. An oil with a single composition may not be able to meet people's daily needs. Although blending oil is a mixture of several oils, linolenic acid may be destroyed during production, so even if you buy blending oil, it is best to buy some virgin oil and mix it with it.
Although the oil is good, but the way to eat is also exquisite, eating oil will hurt the body
Oil reuse, oil temperature is too high, deterioration and other cases will produce toxic substances, so in cooking should pay attention to the oil temperature is not too high. When reusing the oil, because the oil has been destroyed by high temperatures, it may contain toxic oil oxides.
The dosage is exquisite, the recommended daily intake for normal adults is 25-30g, and eating too much oil will cause obesity and increase the risk of cardiovascular disease. Therefore, the amount of oil eaten should be strictly controlled.
It is recommended that you choose the right oil according to the family situation. Develop healthy oil eating habits.
