Sushi types are many, but all include rice. The nigiri or hand-made sushi is the typical sushi and is ordered and served in pairs. Another type includes sushi rolls, or maki, which are made with sheets of seaweed (nori) and served as six slices. There is also stuffed bean curd rolls, or inarizushi.

Sushi and Health

Sushi is a perfect food not only for calorie counters, but also for those following more specific nutritional guidelines. Even the fattiest varieties of fish used in sushi-tuna, salmon, and eel-contain fewer than 200 calories per four-ounce serving. That's about half what you'd get with a prepared steak. Shrimp and octopus are even lower, at only 100 calories per serving. And the fatty fish calories pack the nutritional power of not only protein, B-vitamins, and minerals like selenium, but also Omega-3 fatty acids. Studies continue to demonstrate the enormous role these fats play in maintaining a healthy heart, and metabolism in general. The Omega-3's have even been touted to improve conditions such as arthritis, psoriasis, and depression.

Nori, rice and vegetables add another mere 150 calories per serving. These calories provide more vitamins, minerals, and fiber, especially if brown rice is used, and provide a good source of carbohydrates to complement the fish protein. Even wasabi can claim its own small health benefit, being rich in vitamin C.
