Why don't most Westerners eat animal offal?

In the eyes of the Chinese, there is nothing that can not be eaten, China's culinary culture is profound, many in the eyes of foreigners look inedible things, in our are able to be cooked especially delicious. Including animal offal there are many people are very favorite.

In fact, foreigners also eat animal offal, such as the French people eat cow brain, tripe, cow liver, cow loin, foie gras and other food, pig's blood, pig's liver, sheep's brain, sheep belly and so on also eat; Spaniards eat is also very complex, like tripe, cow's brain, pig's liver, these foods they are also eaten, but also includes animal genitals we do not eat they also eat; Italians are very similar to us in fact, we eat the offal of the animals they are also They also eat all the animal offal that we eat.

It's just that foreigners think that the way we make food is too rough, and that we don't have the refinement that they have for food production. Some foreigners think that our cooking, frying, and boiling methods will bring out the fishy smell of animal offal, and some foreigners think that we don't have a process for making food, and that we don't have the artistic level that they require for food.

In fact, there is a conceptual error here, we say that foreigners do not eat animal offal, this ? foreigners? The width is too wide, covering Europe and the United States, in fact, really do not eat animal offal is the Americans, they do not eat animal offal habits, some Europeans will still eat.

The reason for this is first of all their traditions, and then their belief that organs accumulate more harmful substances than other places, such as heavy metals are usually deposited in the organs, and according to medical science the liver is the most prone to heavy metal deposits.

Western culture, influenced by religion and custom, rejects animal organs as unclean and infectious; in China, however, because of its lifestyle and large population, the exploitation of food, especially animal food, has become the best way to make use of it, with deep processing, refined operation and more cooking, which is the difference between the Chinese and Western food cultures. With the popularity of Chinese food in the world, this difference is changing?
