3) Fish Roe
Fish roe is otherwise known as fish eggs.
While not such a common food in the Western world, it is extremely popular in Japan and Eastern Russia.
Fish roe is also extremely nutritious and packs an impressive amount of nutrients including omega-3, vitamin D, significant amounts of protein, and much more.
There are many different kinds of roe, so there is no set of generic nutritional values.

Some of the most popular types of sashimi include bream, salmon, shrimp, and tuna.
