Salt in China has a long history. In ancient times, salt was regarded as an important resource, not only in cooking, but also in medicine, trade, and warfare.
In China, the history of salt mining and sales can be traced back to around 5000 BC. The earliest salt was made by boiling dried seawater, called sea salt. Over time, people began to exploit salt mines on land, such as well salt in Sichuan and pond salt in the northwest.
In Chinese history, salt is also closely associated with some important events and figures. For example, during the Spring and Autumn Period and the Warring States Period, Guan Zhong and Duke Huan of Qi successfully strengthened the national strength of Qi by reforming the salt industry policy. Zhuge Liang during the Three Kingdoms period also used salt resources to support the army during the Northern Expedition.
In modern China, salt is still an important resource. In addition to its application in cooking, salt is also used to make various salt products, such as iodized salt, low-sodium salt, etc., to meet the needs of different groups of people. Salt, as the first of the five flavors, has always occupied a pivotal position in people's diets.
However, with the process of industrialization and the intensification of market competition, some unscrupulous businesses have actually produced and sold salt harmful to the human body in order to reduce costs and increase profits. Today, I would like to expose the true face of these "invisible killers" and remind everyone to be vigilant against these three kinds of salt, never buy them again, and resolutely throw them away at home! These salts not only hurt the stomach, lungs, but also kidneys, and pose a great threat to health, and are by no means alarmist.
1: Industrial salt pretending to be edible salt. In the market, there is a substance called "industrial salt", which was originally used as a raw material in the chemical, tanning and other industries. However, some unscrupulous traders sell this industrial salt to consumers as edible salt in order to make huge profits. Industrial salt contains a large amount of heavy metals, nitrite and other toxic and harmful substances, and long-term consumption will cause great harm to the human body.
Heavy metals such as lead and mercury in industrial salts can accumulate in the human body, causing poisoning symptoms and damaging the nervous system, digestive system and urinary system. Nitrite, on the other hand, is a strong oxidant that binds to hemoglobin after entering the human body, resulting in a decrease in the blood's ability to transport oxygen, causing symptoms such as dizziness, nausea, vomiting, and even shock and death in severe cases.
2: Excessive addition of anti-caking agent salt. Anti-caking agent is a kind of food additive used to prevent the agglomeration of table salt, and the common anti-caking agent is potassium ferrocyanide. It is safe to use anti-caking agents within the scope specified in the national standards, but some unscrupulous businesses add excessive anti-caking agents in order to pursue profits, which brings potential risks to the health of consumers.
Excessive intake of anticaking agents may cause adverse effects on the human body. For example, potassium ferrocyanide releases potassium cyanide in the body, which has a toxic effect on organs such as the liver and kidneys. Long-term consumption of salts containing excessive anti-caking agents may lead to abnormal liver and kidney function, decreased immunity and other problems.
3: Counterfeit and shoddy low-sodium salt. Low sodium salt is a healthy table salt for people with chronic diseases such as high blood pressure, which reduces the effect of salt on blood pressure by reducing sodium content. However, in order to reduce costs, some unscrupulous businesses use counterfeit and shoddy means to produce low-sodium salts. These pseudo-low-sodium salts often contain large amounts of ordinary table salt or other unknown ingredients, which do not have the effect of lowering blood pressure at all.
Consuming counterfeit and substandard low-sodium salt not only fails to achieve the purpose of controlling blood pressure, but may also aggravate the symptoms of high blood pressure due to excessive sodium intake. In addition, due to the relatively high production process and quality control requirements of low-sodium salts, counterfeit and shoddy low-sodium salts may also have other safety risks.
How to choose edible salt correctly?
1: Choose the type of salt according to your own needs. There are many types of salt, such as sea salt, well salt, lake salt, etc., and the taste and ingredient content of different types of salt are also different. When choosing table salt, you should choose the type that suits you according to your needs and taste preferences. For example, for people with high blood pressure, low-sodium salts can be chosen to control blood pressure.
2: Pay attention to the ingredient content of table salt. When buying table salt, you should pay attention to check the ingredient content table on the product label to understand the content of major ingredients such as sodium chloride and iodine in table salt. At the same time, it is necessary to pay attention to the selection of salt products that meet national standards to avoid excessive intake or substandard ingredients that affect health.
3: There are two main national implementation standards for salt: GB 2721 and GB/T 5461. GB 2721 is a mandatory national standard for edible salt, which represents the most basic requirements and safety standards for edible salt. This standard number covers a wide range of table salts, whether it is ordinary table salt, refined salt, crushed and washed salt, sun-dried salt, and even low-sodium salt, all of which need to meet the requirements of this standard.
GB/T 5461 is a national recommended standard. When buying salt, it is recommended to choose salt with the national implementation standard of GB 2721, which is safer and healthier.
We live in a complex and ever-changing world, facing challenges and difficulties. However, as long as we stick to our inner beliefs and dreams, we will be able to overcome all difficulties and realize our own values.
Success doesn't happen overnight and requires perseverance. Only after the baptism of wind and rain can you see the beauty of the rainbow. Let's move forward bravely, pursue our own ideals and goals, and write a wonderful story for our lives. Come on, stranger......
