Chapter 392 Lard and Vegetable Oil

"Is it so miraculous?"

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

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

"My mother can bake sesame seed cakes, and she can use noodles to make pastry, but for frying, use hot oil to fry the noodles into batter, and use that batter to knead the noodles and make sandwiches."

"I'm just doing the white case. The reason why many common pasta such as sesame seed cakes, fire-roasted pancakes, puff pastry, flower rolls, etc. are delicious outside is because of the addition of lard."

"Didn't you say you can't eat lard? It's unhealthy."

"Who said lard is unhealthy? We have been eating it for thousands of years, why is it unhealthy?"

"Those who say 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 is true that lard is unhealthy, but vegetable oil is even more unhealthy."

"I have been eating lard since I was a child, and I haven't found anything unhealthy."

In the live broadcast room, the audience was still chatting about pastry at first, but before they knew it, 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 bullet screens, Li Yi understood what the audience was arguing about.

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

But if which kind of oil is more suitable for our people to eat, it must be lard. "

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 adapted."

"Let's just say that while those people say that lard is unhealthy, when promoting butter, they also say that animal butter is good, haha!"

"I don't listen to anything else, I just believe that my ancestors have eaten it for thousands of years, and there is nothing wrong with it."

However, some people in the live broadcast room questioned Li Yi's point of view.

"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. Eating too much is really bad for the cardiovascular and cerebrovascular!"

"Vegetable oil is indeed unhealthy, but lard is not much better, right?"

Seeing the doubts from the audience, Li Yi smiled.

"Eh? Don't label me indiscriminately! I didn't say that lard must be healthy! I just said 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. "

Having said that, he paused, glanced at the barrage, and continued with a smile: "I know, there must be audiences who will say that the plant seed oil we use now has a smoke point of around 210°C, so I just Can say you are too young.

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

But why does the seed oil sold on the market have a smoke point of around 210°C~220°C?

This is because many vegetable seed oils have undergone a high-temperature refining process before leaving the factory.

While these processes increase the oil smoke point of seeds, they will destroy the nutrients in them.

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

It will also release harmful substances such as benzopyrene, nitrite, and trans fatty acids, which are harmful to the human body.

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

After 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 family members, letting them see what cooking oil they were eating.

Zhao Jinmai asked in surprise: "Is vegetable oil so unhealthy? My family eats vegetable oil, usually soybean oil and sunflower oil. Are these oils unhealthy?"

"It's not that the oil is unhealthy, it's the cooking method."

Li Yi smiled and said: "We are the only country in the world that heats oil to extremely high temperatures to make dishes, which is the so-called stir-fry.

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

However, the nutrients in lard are not enough, and common vegetable seed oil is rich in omega 6 fatty acids needed by the human body, so it should be eaten at ordinary times. "

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

"Why do you have to choose?"

Li Yi had already kneaded the flour 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 flour.

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

While explaining: "Let's put it this way! The nutrients needed by the human body contained in edible oil are called fatty acids.

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

The fatty acids 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 Omega 3 and 6 cannot be synthesized.

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

However, these vegetable oils have relatively low smoke points and will release harmful substances, so they are not suitable for high-temperature cooking.

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

But Omega 6 is a nutrient that the human body must take in, so we also need to eat vegetable oil.

However, it is best not to heat vegetable oil at high temperature, it is best to come cold.

If you have to use it, it’s best to use a hot pot with cold oil, put the ingredients in as soon as the temperature is up, and fry them at a low temperature, 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, grapeseed oil, etc.

If you have the 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. Whether it is safe or not is directly related to human health.

Everyone has loved ones who care about them. No one will choose to ignore this kind of health problem.

After listening to Li Yi's description, Liu Yifei sorted it out and asked, "That is to say, high-temperature stir-frying is not healthy, and it's best to use lard to stir-fry.

Vegetable oil must also be eaten, it is best to stir-fry with low oil temperature, or directly cold.

If possible, eat some more nutritious oils, right? "

"That's right."

Li Yi gave her a thumbs up and said with a smile, "Give our class representative a thumbs up."
