China people can't cook without oil, and oil is a very important medium in cooking. The most common oils in people's homes are lard and vegetable oil. More and more families advocate eating vegetable oil, which is relatively healthy and has less burden on the body. But how many people know why lard is unhealthy? Let's analyze the efficacy of these two oils and see where the mystery lies.
Nutritional competition between vegetable oil and lard Vegetable oil, as its name implies, is to extract oil from plants, such as peanut oil, soybean oil, palm oil, corn oil and olive oil, which are all compounds of fatty acids and glycerol.
Vegetable oil efficacy
Help metabolism
Fatty acids in vegetable oil can effectively promote cholesterol to enter bile, prevent excess cholesterol from accumulating on the blood vessel wall and prevent atherosclerosis, which is more suitable for people with high weight.
Control cholesterol absorption
The biggest advantage of vegetable oil is that it contains no cholesterol, but now many diseases are inseparable from high cholesterol. Phytol in vegetable oil can not only be absorbed by human body, but also control the absorption of cholesterol by human body, which is simply a healthy oil for patients with three highs.
The main component of lard is saturated fatty acid, which is characterized by high melting point and easy to be solid, so our common lard is milky white paste texture.
Lard effect
Intestinal lubrication
Lard has a good effect on constipation, and its lubricating effect on intestine has been famous since ancient times. As long as you have constipation, you can drink two spoonfuls of lard to moisten your intestines. In addition, lard has a certain bactericidal effect.
Postpartum tonic
Generally speaking, postpartum pregnant women can eat a little lard to nourish their tired bodies. It is recommended to eat the dishes made of lard once or twice a day, which has a good effect on recovering the weak body after delivery.
Compared with vegetable oil, lard has higher saturated fatty acids, so its edible efficacy is not as healthy as vegetable oil. And many people should not eat lard, otherwise it will lead to some health risks.
Obesity and people with cardiovascular diseases should not eat lard, which tends to thicken cholesterol on the blood vessel wall, hinder blood circulation and lead to a decline in blood circulation and metabolism. Lard is indeed the driving force of the three high diseases, so it should be eaten less.
For people who need to lose weight or shape, eating less lard is conducive to maintaining a low-calorie diet and reducing the burden on the body.
