一、文章内容
Humans have been consuming snails for thousands of years. Snails are very high in proteins, iron, and water, while being low in fat. Snail consumption is popular in various countries around the world. Currently, the global snail farming or heliciculture industry achieves sales of greater than $12 billion annually. Let’s take a closer look at the consumption of snails.
Snail consumption and cultivation are popular to varying degrees in France, the U.S., Turkey, China, Indonesia, Italy, Spain, as well as African countries including Algeria, Cote d’Ivoire, Nigeria, and Ghana. In France, the delicacy known as escargot is an actually cooked snail. Escargot is very popular in many parts of Europe as well.
Based on archaeological evidence, it is known that ancient humans ate snails. Piles of empty snail shells have been uncovered at many prehistoric sites. A study reveals snails used to be an extra food source for Palaeolithic humans in Spain. For over 30,000 years, the Iberus aloneness snail has played a role in the gastronomy of Spain. The Benidorm area of Spain is believed to be the first recorded place where humans consumed snails. Around 10,000 years later, people along the Mediterranean coast of Northern Africa, Italy, France, Greece and the Middle East were eating snails.
Eating snails started in the United States in the 1850s. During that time, snails were sold in the markets in California along with vegetables and fruits. The popularity of escargot has led to having a separate National Escargot Day in the United States celebrated on May 24th each year.
It should be stressed that not all species of land snails are edible. Some most commonly eaten species of land snails include Helix pomatia, Cornu aspersa, Helix lucorum, Iberus aloneness and Elona quimperiana.
People who eat snails find snails to be delicious as the main course or as an appetizer. There are plenty of recipes, especially in European countries, that include snails. Finding snails on the menu is common in elite restaurants in Europe. As already mentioned, Escargot is a very popular snail dish. It is prepared with parsley butter and garlic and served in snail shells. Snails are also used in sauces and poured over various types of pasta in Italy and Greece.
