The Xiaohan solar term came as scheduled, and the market was full of people.
Wang Dawei, an ordinary accountant, with a hint of winter chill, shuttled through the bustling crowd, intending to buy some mutton to stew at home.
That's when he met Dr. Lee, an old friend with a strong medical background.
After the two exchanged pleasantries, Wang Dawei mentioned some of his recent health concerns.
After hearing this, Dr. Li asked carefully and said with a smile, "You know, there is a very strange point of view now, although it sounds not directly related to the health issues we are discussing, but it actually contains profound medical knowledge. ”
"Oh, what's the point?" asked Wang Dawei curiously.
Dr. Lee smiled mysteriously, "Have you ever heard that someone thinks that blowing a fan causes arthritis?"
Wang Dawei was stunned, this does sound ridiculous. Dr Lee continued: "This may seem absurd, but it actually reveals a deeper impact of the microenvironment on health.
While there is no scientific basis for the claim that blowing fans causes arthritis, it inadvertently points to an important issue – the impact of ambient temperature on joint health. ”
Wang Dawei was fascinated by the listen, and Dr. Li continued to explain in depth: "For example, being in a cold or humid environment for a long time may indeed worsen the symptoms of joint pain or arthritis.
And the principle behind this is that low temperatures cause blood vessels to constrict, reducing the blood supply to joints and muscles, which can lead to pain and stiffness.
And prolonged blowing, especially in cold environments, can indeed inadvertently exacerbate the condition. ”
"So what does this have to do with microwaving food?" Wang Dawei asked.
Dr. Lee smiled, "It's actually a good springboard.
When we talk about environmental impact, the safety of microwave food is also an environmentally related health topic.
As you know, microwave ovens use radiation to make food molecules vibrate to produce heat, thus achieving the purpose of heating food.
There has been a lot of controversy in society about whether microwave ovens are harmful or not. ”
Mr. Wang nodded, indicating that he had heard of the controversy.
Dr. Lee continued, "First of all, we need to know that microwave ovens use microwave radiation, which is non-ionizing radiation and is not energetic enough to damage the molecular structure or cause radioactivity in food.
From the available scientific research, the proper use of microwave ovens to heat food is safe and does not cause food toxicity or carcinogenicity. ”
"But," Dr. Lee said, "that doesn't mean microwave ovens are completely risk-free."
For example, improper use, such as heating for too long or using a container that is not suitable for microwaves, can indeed lead to the loss of nutrients in the food or the production of some compounds that are not good for the body.
Also, uneven microwave heating can cause some parts of the food to overheat, causing problems such as scalding. ”
Wang Dawei listened very carefully, and he found the information very useful.
Dr. Lee gave another specific example: "I once had a case where a patient often used a microwave oven to heat food, but because he was always in a hurry to eat it, he didn't stir the food adequately, and ended up eating the overheated part, which caused burns to the oral mucosa. ”
Wang Dawei shook his head and sighed.
Dr. Lee concluded, "So, whether it's blowing a fan or using a microwave, the key is to use it correctly and in moderation.
We can't completely dismiss the benefits of a technology just because of some unfounded claims, but we can't ignore the potential risks.
As consumers, we need to understand the science and make informed choices. ”
The two were chatting energetically, Wang Dawei's mobile phone rang, and it turned out that his family urged him to go back to make dinner.
They hurriedly said goodbye, but Wang Dawei kept thinking about what Dr. Li said.
As he walked briskly home, a question popped up: since uneven microwave heating can cause some parts of the food to overheat, is stirring food while cooking really effective in avoiding this problem?
To answer this question, let's take a closer look at how microwave ovens work and the process of heating food.
The microwave radiation produced when a microwave oven works causes water and other molecules in food to vibrate, resulting in heat.
Due to the limited penetration capacity of microwaves, it is usually only effective in heating the outer layer of food, and the inner layer is mainly heated by heat conduction.
This is the reason why the surface of the food may already be hot when microwaved and the inside is still cold.
Stirring food can indeed help the food heat up more evenly to a certain extent, as it can move the cold part that would otherwise be inside the food to the outside to receive more microwave radiation.
However, stirring does not completely solve the problem of uneven heating, especially for foods that are thicker or irregularly shaped.
For these foods, there may be a lack of internal heating even when stirred.
First, choose foods that are suitable for microwave heating, and try to avoid heating foods that are bulky and thick.
Secondly, covering the food with a microwave-specific lid or insulating film can help distribute the heat more evenly between the inside and outside of the food.
Thirdly, appropriately reducing the power of the microwave oven and extending the heating time will also help the food to heat more evenly.
Finally, stirring food in a timely manner during the heating process, especially for liquid or semi-liquid food, can effectively avoid the problem of local overheating.
By doing so, we can not only avoid the risk of uneven heating of food, but also better preserve the nutrients and flavor of the food.
Of course, no matter which method is used, we need to be vigilant when using the microwave oven to avoid overheating or improper use to ensure that it is safe and healthy to eat.
