Note:
While shrimp paste has a delicious and unique flavor, nitrites are produced during the pickling and fermentation process. Nitrite in the acidic environment of the gastrointestinal tract can be converted into nitrosamines, which is a carcinogen that has been recognized in animal experiments, while the animals have teratogenic and mutagenic effects. It can be seen that shrimp paste can only be used for flavoring, and should not be consumed in large quantities.
When eating shrimp paste, it is best to eat more fresh vegetables and fruits rich in vitamin C, which can block the synthesis of nitrosamines in the stomach. In addition, since shrimp paste generally contains about 30 percent salt, it is best not to consume it for those who need to limit their salt intake.
