The health benefits of sushi
Sushi comes in such a staggering variety that many menus offer a pictorial glossary to help you order. Because of this diversity, the nutritional value of one roll to the next can vary. In general, fish provides a lean source of low-calorie, high quality protein. It's also low in saturated fats and cholesterol, making it a heart-healthy food choice. Salmon is especially high in omega-3 fatty acids, which are linked to improved cholesterol levels, lowered blood pressure, and decreased risk of abnormal heart rhythms. Mackerel, lake trout, herring, and tuna also have omega oomph.
The thin sheets of seaweed, or nori, which are flattened, cut, and wrapped around maki and hand rolls, contain mighty minerals. Iodine, essential for proper hormone function, is abundant in this dried sea vegetable. You'll also get the benefit of magnesium, calcium, iron, and antioxidant phytonutrients and folic acid from eating rolls wrapped in nori.
There was an article written today for yahoo. I'm going to do some more research to see what I can find about iodine.
