Alum is often added in the process of making vermicelli, in order to solve the problems of sticking and broken vermicelli. The main component of alum is potassium aluminum sulfate, which contains more aluminum. Therefore, eating too much vermicelli will lead to an increase in aluminum intake in the body.

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 is toxic to the 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 make the ovaries atrophy and cause fetal growth stagnation.

3. Aluminum can also cause cholestasis liver disease, osteomalacia and hypochromic anemia of blood cells.

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

Causes of harm:

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

2. Suggestions on eating vermicelli:

Not all vermicelli contain alum. At present, more and more manufacturers have developed vermicelli without alum and with guaranteed quality. We must pay attention to the selection when buying.
