Why do many people say that eating rice noodles will make you mentally retarded?

I think this statement is not credible, but in the process of making rice noodles, something called alum is added. If you eat too much, it will be bad for your health. Some people say that it will cause Alzheimer's disease, which is far from mental retardation.

Rice flour is the potato flour we usually eat, but it is very fine in the production process, but it is not like vermicelli, and most of the rice flour we eat is very strong, which means it is very elastic.

Alum should be added to these potato powders during the production process. The scientific name may be added with some alum. The main function of adding alum is to make vermicelli firm, increase elasticity and not break easily when folding.

But alum itself has some disadvantages, because alum is a chemical containing aluminum. According to scientific research, alum containing aluminum ions is difficult to be excreted from the kidneys, which will affect the brain, spleen and kidneys. If it is used excessively, it will probably cause Alzheimer's disease.

Now some vermicelli are not made of alum, so if we want to eat rice noodles, we must distinguish between vermicelli with alum and vermicelli without alum.

If you eat too many alum fans, you may have Alzheimer's disease. If you say that there will be stagflation, I think there is no scientific basis.
