Chapter 391: Lard and Vegetable Oil

"Is it so amazing?"

Listening to Li Yi's explanation, Huang Xiaoming didn't know what to do.

In the live broadcast room, the audience was also discussing curiously.

"My mom would make the cakes, and she would use the noodles to make puff pastry, but when they were fried, they would fry the noodles into a batter with hot oil, and use that batter to mix the noodles and make the filling."

"I'm just making white cases, and many common pasta dishes such as baked cakes, fire cakes, mille-feuille cakes, flower rolls, etc., are sold delicious outside because of the addition of lard."

"Didn't you say you couldn't eat lard? Unhealthy. ”

"Who says lard is unhealthy? We've been eating it for thousands of years, so why is it unhealthy? ”

"Those who say that lard is unhealthy are those who sell vegetable oil, otherwise how can their oil be sold?"

"Anyway, I like to stir-fry vegetables with lard, it's very fragrant."

"It's true that lard is unhealthy, but vegetable oil is even less healthy."

"I grew up eating lard, and I didn't find anything unhealthy."

In the live broadcast room, the audience was still chatting about puff pastry at first, but unconsciously, the topic turned to whether lard is healthy or not.

Zhao Jinmai noticed the audience's barrage, so he asked Li Yi: "Brother Yi, the audience is talking about whether lard is healthy or not, is lard really unhealthy?" ”

Hearing this, Li Yi looked up at the barrage.

After reading a few barrages, Li Yi understood what the audience was arguing about.

So, while kneading the dough, he explained: "From a health point of view, then no matter what kind of oil, eating too much is not healthy."

But if what kind of oil is more suitable for our Chinese people, it must be lard that is more suitable. ”

Hearing Li Yi's explanation, the audience who supported lard in the live broadcast room suddenly became excited.

"Look! Brother Yi said it all! Lard is better! ”

"After eating lard for thousands of years, our stomachs have long been used to it."

"Let's just say, those people say that lard is unhealthy, and when they promote cream, they say that animal cream is good, haha!"

"I don't listen to anything else, I just believe that my ancestors have eaten for thousands of years, and nothing has happened."

However, there are still some people in the live broadcast room who have questioned Li Yi's views.

"Brother Yi is very good at cooking, but you can't talk nonsense, right? The saturation of lard is too high, and the cholesterol is also high, and eating too much is indeed not good for cardiovascular and cerebrovascular diseases! ”

"Vegetable oil is really unhealthy, but lard is not much better, is it?"

Seeing the doubts of this part of the audience, Li Yi smiled.

"Huh? Don't give me a hat! I didn't say lard was necessarily healthy! I'm just saying that lard is more suitable for Chinese people. ”

Li Yi explained: "In fact, from a nutritional point of view, lard is actually not nutritious, it does not have the essential omega-3 and omega-6 fatty acids.

The reason why I say it is more suitable for Chinese people is because its smoke point can reach about 230°C, which is very suitable for our Chinese cooking habits. ”

Speaking of this, he paused, glanced at the barrage, and then continued with a smile: "I know, there must be viewers who will say that the plant seed oil we use now has a smoke point of about 210 °C, so I can only say that you are too young."

In fact, 90% of plant seed oils have a smoke point of only about 160°C.

But why can the smoke point of the seed oil sold on the market reach about 210 °C ~ 220 °C?

This is because many plant seed oils have undergone a high-temperature refining process before they leave the factory.

These processes increase the smoke point of seeds while destroying the nutrients in them.

When we consume this oil for a long time, not only can we not obtain the nutrients needed by the human body, but will produce a large amount of smoke harmful to the human body during the cooking process.

It also releases benzopyrene, nitrate salts, trans fatty acids that are harmful to the human body.

Among them, benzopyrene and nitrate are both substances defined by the World Health Organization as Class A carcinogens, and long-term consumption is absolutely unhealthy. ”

Listening to Li Yi's explanation, everyone present became serious.

Even the staff in the rear began to take out their mobile phones to send messages to their families, asking them to see what kind of cooking oil they were eating.

Zhao Jinmai was surprised and asked: "Is vegetable oil so unhealthy?" My family eats vegetable oil, generally soybean oil, sunflower oil, are these oils unhealthy? ”

"It's not that the oil is unhealthy, it's the way it's cooked."

Li Yi smiled: "We are the only country in the world that will heat oil to an extremely high temperature to make dishes, which is called stir-frying.

The reason why lard is more suitable for us is that it has a higher smoke point and produces fewer harmful substances.

However, the nutrients of lard are not enough, and common plant seed oil is rich in omega-6 fatty acids required by the human body, and it is usually eaten. ”

Zhao Jinmai was confused by Li Yi's words: "Then which oil is the best?" Lard is more suitable, vegetable oil is nutritious, so how to choose? ”

"Why do you have to choose?"

Li Yi had already kneaded the dough in the basin into a whole dough.

But he didn't stop, the dough was still a little sticky, and the inner wall of the basin was covered with batting.

He pushed the dough with the back of his palm, let it rub against the wall of the basin, rubbed the dough off the wall of the basin little by little, and kneaded it into the dough.

While explaining: "Let's put it this way! Edible oil contains nutrients that are needed by the human body called fatty acids.

It is divided into saturated fats of animal fats and fats, and unsaturated fats of vegetable fats.

The fatty acids that our body needs are omega 3, omega 6, omega 7 and omega 9.

Among them, omega 7 and omega 9 can be synthesized by the human body, while 3 and 6 cannot be synthesized.

Omega 6 is mainly found in plant seed oils such as peanut oil, rapeseed oil, sunflower oil, corn oil, and soybean oil.

However, these vegetable oils have a relatively low smoke point and will release harmful substances, making them unsuitable for high-temperature stir-frying.

Therefore, when we usually stir-fry, it is best to fry with lard, which is safer.

But omega-6 is a nutrient that the human body must ingest, so we must also eat vegetable oil.

However, it is best not to heat vegetable oil at high temperatures, and it is best to mix it cold.

If you have to use it, it is best to heat the pan with cold oil, just put down the ingredients as soon as the temperature is up, and use low temperature to slide and fry, which is the healthiest.

In addition, the omega-3 I just mentioned is also an essential nutrient for the human body.

This fatty acid is mainly found in oils such as flaxseed oil, perilla seed oil, walnut oil, hemp oil, grape seed oil, etc.

Usually, if there are conditions at home, you can also eat with these oils, which will be healthier. ”

Listening to Li Yi's explanation, everyone present looked serious.

Edible oil is something that everyone usually eats, and its safety is directly related to human health.

Everyone has relatives who care about them in their families, and no one will choose to ignore this kind of health problem.

Liu Yifei listened to Li Yi's description, combed it a little, and asked: "In other words, stir-frying vegetables at high temperature is not healthy, so it is best to fry them with lard."

Vegetable oil should also be eaten, and it is best to stir-fry vegetables at low oil temperature, or directly cold dressed.

If you can, take some more nutritious oils, right? ”

"That's right."

Li Yi gave her a thumbs up and said with a smile: "Give a thumbs up to our class representatives." ”
