Hello, it is better for families to eat oil with high unsaturated fatty acid content for a long time. Using unsaturated fatty acid edible oil at home can supplement some unsaturated fatty acids that the human body cannot synthesize by itself.

I recommend the following edible oils:

1, olive oil: olive oil is generally squeezed directly without chemical treatment, with a high content of unsaturated fatty acids. It is an edible oil that meets the nutritional needs of the human body, especially suitable for cold dishes, but not suitable for cooking, and the price is relatively high;

2. Rapeseed oil: The oleic acid and linoleic acid content of rapeseed oil is the highest in edible oil, and its unique campesterol is more easily absorbed by human body, with lower cholesterol content and higher vitamin content, which is suitable for cooking, but the erucic acid contained may be bad for human body, so it is recommended to choose rapeseed oil without erucic acid;

3. Peanut oil: The saturated fatty acid content of peanut oil is higher than that of other vegetable oils, and the cooking is more fragrant, but the linolenic acid content is less. In addition, peanut oil is easily polluted by aflatoxin during processing, so it is recommended to buy products from regular manufacturers;

4, soybean oil: it is the most commonly used edible oil, rich in nutrients such as carotene, vitamin E, sterol, etc. Soybean oil is very fragrant but has a short shelf life, so it needs to be used as soon as possible, and some soybean oils on the market have genetically modified products, so those who care need to be careful;

5. Sunflower seed oil: The oleic acid content is high, and it is rich in tocopherol with biological activity, but the linolenic acid content is low, so it can be used in baking besides cooking;

6, corn oil: the price is relatively close to the people, and it is rich in vitamin E. Its saturated fatty acids and unsaturated fatty acids are high, but its heat resistance is poor, which is not suitable for high-temperature frying.

But no matter what kind of oil you eat, you can't eat too much, and you need to control the oil intake according to your personal situation. For example, people who are engaged in heavy manual labor or have a lot of exercise need to eat about 30 grams a day, and others had better not exceed 25 grams. Different edible oils have their advantages, so you can choose them according to your needs.
