7. Sushi
It’s long been known that the Japanese have some of the longest lifespans of all the people in the world and one reason for that could be sushi. Fish contains a high concentration of omega-3 fatty acids and those are associated with a healthy heart and lower levels of inflammation, which is suspected as a major contributor to a number of serious diseases. There are currently more than 65,000 people in Japan that are over the age of 100 and a good part of that could be due to their diet, which includes a lot of fish.
