In the process of making vermicelli, alum is often added to solve the problems of sticking and breaking. The main component of alum is potassium aluminum sulfate, which contains more aluminum. Therefore, eating too many fans will lead to an increase in aluminum intake.

The hazards are as follows:

Aluminum is not an essential element for human body. Long-term high-dose intake of aluminum will lead to its accumulation in the body and bring a series of diseases.

1. Many experiments at home and abroad have confirmed that aluminum has toxic effects on cranial nerves, which will interfere with people's consciousness and memory function and lead to Alzheimer's disease.

2. Excessive intake of aluminum by pregnant women will cause ovarian atrophy and cause fetal growth stagnation.

3, aluminum can also cause cholestasis of liver disease, leading to osteomalacia and hypopigmentation anemia of blood cells.

4. In recent years, many studies have confirmed that aluminum may cause damage to antioxidant system and genetic material DNA.

Cause of injury:

Some studies believe that aluminum will interfere with the absorption of elements such as copper, zinc, manganese and selenium. When the levels of copper, zinc, manganese and selenium decrease, the human body will produce a large number of free radicals harmful to health.

Second, suggestions on eating vermicelli:

Not all fans contain alum. At present, more and more manufacturers have developed alum-free quality fans. Be sure to pay attention to selection when buying.
