It is said that food is the basic condition for our survival, but now with the improvement of people's living standards, food brings us not only food and clothing, but also spiritual enjoyment. People's requirements for food are getting higher and higher, not only nutritious and healthy, but also hygienic. After all, what you eat in your stomach must be strictly controlled, so everyone washes their hands before and after meals, for fear that the food made is unsanitary.

But I didn't know that many foods we ate were trampled by our feet when they were being made. It is hard for everyone to imagine how the food we eat in our stomachs is associated with foot odor, but in fact it is. So let's share with you today which foods were stepped on by our feet during the production process, and don't feel sick. Most people have eaten at least one kind, see if you have.

The first kind: salt

Salt is an indispensable substance in our life and a very important condiment. It's hard to imagine how we can live without salt. What we eat is tasteless. In ancient times, the method of making salt was that people extracted salt from saltworks and dried it. At this time, there will be a lot of salt with larger particles.

People step on salt with their feet, so that large particles of salt are crushed into small particles, and drying will save a lot of time. This salt-making method has been passed down to this day, and many people are still continuing this salt-making method.

The second kind: wine

Wine has a history of thousands of years. It is said that in the initial brewing of wine, girls' feet were used to step on it, which can promote the fermentation of grapes. You may think that this kind of wine will still be drunk, but in fact, most people really can't afford it.

It is said that only rich and influential people could afford this kind of wine at that time. Of course, now wine is produced by assembly line, which takes a short time and is clean and hygienic, but there are still few places that like to make wine in this way.

The third kind: tea

I believe many people have the habit of drinking tea. Tea is an ancient "drink" in China, and tea culture has existed for thousands of years. In ancient times, technology was not as advanced as it is now, so people would use artificial pedals in the process of making tea, because tea needs to be kneaded, which is also a crucial process.

Rubbing tea is also very labor-intensive. Female workers take off their shoes and step on tea barefoot. Now this method has been replaced by machines, but many people think that machines are not mellow enough, so there are still many places that still use the method of rubbing tea with their feet.
