Sushi is a kind of food containing rice and flavored with rice wine vinegar. Some sushi contains sashimi, while others may use cooked fish or vegetables. There are many kinds of sushi, including sashimi sushi or hand-rolled sushi. This kind of sushi is made by hand with rice balls, and a piece of shellfish, fish or other ingredients is added, in addition to mustard sauce. Sushi set meal is a kind of sushi wrapped in seaweed. Mixed sushi includes mushrooms, kelp or sashimi. Vegetarian sushi is made in the same way as other types of sushi, but vegetables such as carrots and cucumbers are used instead of raw fish.
As the source of protein, the history of sushi can be traced back to the 4th century BC. Sushi was originally made of fermented rice and salted fish. Fish are eviscerated, cleaned and put into rice, so that fish can be preserved by natural fermentation. After two months of fermentation, the rice was discarded and the fish could eat.
Sushi offers different kinds of fish to choose from. In addition, it is a low-calorie substitute for red meat and high-fat food. Sushi used to be served only in some restaurants, but now it has become very popular in many countries and regions.
Almost all raw fish, shellfish and seafood contain the same vitamins and minerals. However, the exact number depends on the kind of fish. Some nutrients include protein, water, lipids, carbohydrates, ash, sodium, potassium, calcium, magnesium, phosphorus, iron, zinc, manganese, vitamin A (retinol), vitamin A (carotene), cholesterol and fatty acids. Vegetable sushi also contains vitamins A and C, as well as calcium and iron.
Although eating sushi is a healthy way to get all vitamins and minerals, it is not suitable for everyone. Because of the use of sashimi, many people find it difficult to accept it. Besides, not everyone can accept the special taste of sushi.
