The main reason for salt iodization is to prevent iodine deficiency diseases. Iodine is one of the essential trace elements in the human body and an important raw material for the synthesis of thyroid hormones. Thyroid hormone is essential for human growth and development and the maintenance of normal physiological functions, and is essential for children's brain development and physical development.
Iodine deficiency diseases are a series of diseases caused by low iodine content in plants and grains caused by the lack of iodine in water and soil in the natural environment, resulting in insufficient iodine intake in the human body. Long-term iodine deficiency can affect thyroid function, leading to goiter, cretinism, acrettinism, etc. These diseases can have a serious impact on people's health, such as mental retardation, stunted growth and development, physical deformities, etc.
In order to prevent iodine deficiency diseases, the State has adopted a policy of salt iodization. By adding an appropriate amount of iodine to table salt, the intake of iodine in people's daily diet is improved, and the human body's demand for iodine is met, thus effectively preventing the occurrence of iodine deficiency diseases.
Salt iodization is not only good for individual health, but also for society as a whole. Through the implementation of the salt iodization policy, people can obtain sufficient iodine nutrition and maintain a healthy physical state, thereby improving labor productivity and social productivity. In addition, the implementation of the salt iodization policy has also reduced the medical burden and social costs, which has brought a positive impact on the development of the whole society.
It is worth noting that salt iodization is not overdosed, but scientifically added according to the body's demand for iodine. Excessive iodine intake can also have negative health effects, so when using iodine-containing products, the principle of moderation should be followed.
In conclusion, salt iodization is used to prevent iodine deficiency diseases and maintain good health. Through the implementation of the salt iodization policy, people can obtain sufficient iodine nutrition, improve physical fitness and social productivity, and contribute to the development of the whole society. In daily life, we should pay attention to the moderate intake of iodine-containing foods and maintain a healthy lifestyle.
