Is animal oil better or vegetable oil better

People need to use oil when cooking, but when going to the supermarket to buy oil, people should find that there are many types of oil, which can be simply divided into two categories, animal oil and vegetable oil. Some people prefer to buy animal oil, while some people prefer to buy vegetable oil. So, animal oil or vegetable oil is better? This issue has always been controversial, so let’s analyze it in detail below.

There is no perfect food in the world, and there is no oil that is best for the human body. Even the popular olive oil has its shortcomings. There is no single oil that is most beneficial to the body. Each oil has its own advantages and disadvantages. Edible oils should be diversified and reasonably matched. Therefore, the best solution is to use a variety of cooking oils together.

Fatty acids are important for our health, but we must understand the following :

1. Linoleic acid and linolenic acid are essential fatty acids for the human body. The human body cannot synthesize them and can only obtain them from food. If they are lacking, it will affect the body's immunity, wound healing, vision, brain function and cardiovascular health.

2. Saturated fat, which is mainly found in abundant animal oils, is an unhealthy factor that causes dyslipidemia, high blood pressure and atherosclerosis.

3. Oleic acid can regulate blood lipids, lower blood cholesterol, triglycerides and low-density lipoprotein (bad cholesterol, LDL), and increase high-density lipoprotein (good cholesterol, HDL).

Now let’s look back at the four types of cooking oils mentioned in the question. Due to the different proportions of various fatty acids, their nutritional characteristics are also different.

Peanut oil : Peanut oil is extracted from peanut kernels. It has high ratios of oleic acid and linoleic acid and low content of linolenic acid. It also contains nutrients such as sterols, phospholipids, vitamin E, etc. Overall, its nutritional value is similar to that of corn oil. It is highly heat-resistant and healthier, and can be used for cooking and frying.

Corn oil : It is extracted from corn germ. It has a high proportion of polyunsaturated fatty acids, but low levels of linolenic acid and oleic acid. It is rich in nutrients such as vitamin E and phytosterols, and is a vegetable oil with high nutritional value. From a health perspective, it is a good oil and is good for health. However, due to its high content of polyunsaturated fatty acids, it is not particularly heat-resistant and it is best to use it less in making foods that are fried or deep-fried at high temperatures.
