"Lao Li, do you know? Many people don't pay attention to the step of oil when cooking, in fact, it is to 'drug' themselves! ”
Dr. Zhang said with a smile at the entrance of the community to Li Dong, who had just returned from buying fish from the river.
Li Dong is a middle-aged project manager working at the Municipal Works Bureau, with a passion for food and cooking. On this day, he bought a fresh crucian carp and prepared to go home to entertain some old friends.
On the way, I happened to meet my neighbor, Dr. Zhang, so we went home together and started chatting.
Dr. Zhang continued, "Are you going to make braised fish? I warn you that the fish has to be oiled, otherwise it will taste much worse. ”

Li Dong responded with a smile: "Doctor Zhang, I have a set of braised fish, but what is the point of this oil?" Isn't it just to remove the smell and increase the fragrance? ”
Dr. Zhang waved his hand: "Where is it so simple, oiling is not only to remove the smell and increase the fragrance, but also to consider health." ”
Hearing this, Li Dong became interested: "Oh? I really didn't think that this oil could have anything to do with health. ”
Dr. Zhang smiled and said, "Of course, if I tell you a story, you will understand." ”
There was once a patient named Xiao Zhao, a young white-collar worker, who was usually busy with work and often cooked at home by himself.
He likes spicy food, and often puts all kinds of chili peppers, peppercorns and minced garlic directly into the pot, which he finds so simple and convenient, but soon he finds himself indigestion and gastrointestinal discomfort. In the end, I had to come to the hospital for help.
Dr. Zhang continued, "There are many people like Xiao Zhao, and many people think that cooking oil is just for the sake of looking good or improving the taste, but this is not the case. The purpose of over-oiling is to allow the components of these condiments to be released better.
Something like capsaicin must be fried at high temperatures to be able to fully exert its effects. ”
Li Dong nodded: "In this way, there is still a scientific basis for oiling." ”
Dr Teo continues, "Yes, many condiments contain active ingredients that need to be treated with oil to fully release, such as capsaicin in chili peppers, alliin in garlic, and aroma components in spices.
These ingredients not only affect the taste, but also promote digestion, bactericide, and anti-inflammatory. ”
He added: "According to studies, capsaicin is released in oil more than twice as efficiently as other ways. This means that many of the nutritional and health benefits are not available without frying. ”
In order to give Li Dong a better understanding, Dr. Zhang gave a case of a friend who had not eaten fried food for a long time and thought it would be healthier.
As a result, every time I eat food that contains a lot of garlic and chili peppers, I feel upset in my stomach. Later, I tried to over-oil these ingredients, and the symptoms were relieved.
"This is because over-oiling not only makes the ingredients more delicious, but also reduces the direct damage to the stomach and intestines caused by irritating ingredients to a certain extent." Dr. Zhang explained.
At this time, Li Dong thought of the dishes he often made, and asked thoughtfully: "Will the oil make the food unhealthy?" For example, will too much oil cause cardiovascular disease? ”
Dr. Zhang shook his head and said, "The key lies in the choice of oil and the amount of oil used. We need to use suitable oils, such as olive oil, rapeseed oil, etc., which have a high smoke point, are suitable for over-oil treatment, and do not produce harmful substances.
And as long as you pay attention to the oil quantity control, you don't actually have to worry too much. ”
Li Dong smiled: "It sounds like oil is still a science." ”
"Of course," Dr. Zhang said, nodding, "the process of oiling may seem simple, but it is actually related to nutrient release, flavor enhancement, and health protection.
In the case of garlic, alliin is converted to allicin when oiled, which helps lower blood pressure and is anti-inflammatory. But if you eat it raw, a lot of the ingredients are wasted. ”
Dr. Zhang continued, "For example, the oil-soluble capsaicin of Sichuan pepper can only be released after passing through the oil, which is not only a source of spicy taste, but also has a certain analgesic and anti-inflammatory effect. ”
At this time, the two had already walked to the door of the community, and Li Dong said while opening the door: "Today can be regarded as a long experience, it seems that I have to take the step of oil seriously." ”
Dr. Zhang patted Li Dong on the shoulder: "Don't worry, as long as you master the method, over-oiling will not only make the food more delicious, but also healthier." ”
In the ensuing gathering, Li Dong did the same, applying the knowledge taught by Dr. Zhang to the actual cooking, and the oiled fish fillets were really fragrant, and his friends were full of praise for eating.
A few days later, Li Dong overheard his colleague Xiao Li discussing that he had been having a stomach discomfort lately, and Li Dong immediately thought of what Dr. Zhang had said, and enthusiastically shared what he had learned:
"Xiao Li, when you were cooking recently, did you ignore the step of oil?"
Xiao Li was stunned and said, "Hey, don't say it, I like to fry it directly, I think it's convenient." ”
Li Dong smiled slightly: "That's the problem. Many spices can only work better if they have been oiled, which not only makes the dish more fragrant, but also makes your appetite comfortable. ”
Xiao Li asked suspiciously: "Is it really so magical?" ”
Li Dong nodded seriously: "Yes, I heard a lot of truth from Dr. Zhang that day, especially like garlic and chili, after oil treatment, your stomach will be more comfortable." ”
After Li Dong finished speaking, he added: "Of course, you also have to pay attention to the choice and amount of oil, don't overuse oil, as long as you fry it a little, you can achieve the effect." ”
Xiao Li listened to it and decided to go back and try it.
A few days later, Xiao Li excitedly ran over and told Li Dong: "You are so right! I've been cooking for a lot lately, and my appetite has improved a lot! ”
Li Dong smiled and patted him on the shoulder: "Look, I didn't lie to you, it's all the credit of Dr. Zhang."
Through this incident, Li Dong became more aware of the seemingly simple cooking steps, but there is actually a lot of health knowledge behind them. And because of this, he became famous in the company and was nicknamed "a little health expert" by his colleagues.
As time passed, Li Dong's health awareness gradually strengthened, and he began to explore more healthy eating methods in his life.
He noticed that the nutritional value and health effects of different ingredients can vary greatly under different cooking methods.
He even enrolled in a course in nutrition to learn more about the relationship between food nutrition and health.
Through these studies, Li Dong learned that the hidden nutrients in many ingredients require specific cooking techniques to be better absorbed and utilized by the human body.
For example, some antioxidant-rich vegetables, such as tomatoes and carrots, can be better absorbed by the body by heating and using the right amount of oil.
Li Dong shared this knowledge with his friends, and everyone said that they benefited a lot. Not only that, but he also organized a healthy cooking workshop in the community, which attracted many neighbors to attend, and Dr. Zhang was also invited as a guest.
At the lecture, Li Dong not only shared the benefits of oil, but also explained in detail how to scientifically and rationally cook at home to ensure a healthy diet.
At the end of the talk, Dr. Cheung concluded, "Healthy eating is not only about controlling calorie and nutrient intake, but also about understanding how to maximize the nutritional value of food. This requires us to apply scientific knowledge to our cooking. ”
Amid applause, Dr. Li Dong and Dr. Zhang greeted each other and thanked each other for their joint efforts on the road to healthy eating. Through this sharing, Li Dong not only improved his own health level, but also contributed to the health cause of the community.
However, Li Dong still has a question in mind: what seemingly simple cooking steps in our daily diet actually contain profound health science? If you don't pay attention to these details, will you miss out on a lot of health benefits?
In order to find the answer to this question, Li Dong decided to continue his exploration and delve into the relationship between cooking and health, looking forward to bringing a healthier lifestyle to himself and his family.
In his spare time, he plans to look up more information and experiment with different cooking methods to uncover the mysteries behind this.
Through such continuous learning and practice, Li Dong hopes to pass on the concept of healthy eating to more people, so that everyone can achieve a win-win situation of deliciousness and health in life.
This is not only his personal pursuit, but also a kind of love and responsibility for life.
