food can interfere one’s physical status

For several times I ate a kind of food bought from the market what have being produced in current way for more than 40 years, I felt not very clear and clean in physical status in the day after that, like my body system was influenced by somethings.

I think it’s caused by the additive of the food.

I don’t know why essence is introduced to the food. More than ten years ago, people around started against MSG in the kitchen like early waken ones. Now I realized most of the seasonings of the food made from the factory is not good for body.

So food factories should stop use additive for taste, only put preservatives as less as possible. If the industry can improve the providing system, maybe food no longer need preservatives in the future.
