Is frozen food necessarily unhealthy?

Eating frozen food for a long time usually doesn't do much harm to your health. Regular frozen food is generally to quickly freeze fresh raw materials after industrial treatment in order to achieve the purpose of long-term preservation. Usually, there is no preservative component, which will not cause a lot of nutritional loss. For frozen foods that have not exceeded the shelf life or deteriorated, long-term moderate consumption will generally not cause much harm to the body.

In order to preserve frozen food conveniently, more seasonings such as oil, salt or sugar are usually added, so patients with hypertension, nephritis and diabetes are not suitable for eating frozen food in large quantities for a long time, which is not conducive to disease control. In addition, although microorganisms are not easy to reproduce at low temperature, they may breed germs, such as psychrophilic bacteria. If frozen food expires or goes bad, it may increase the chance of gastroenteritis after eating. Therefore, it is recommended to eat more fresh meat, fruits and vegetables at ordinary times, which is relatively safe and hygienic and can reduce the occurrence of discomfort.
