Although salmon certainly has many different nutritional and health benefits, so does tilapia. On average tilapia has more protein and less overall fat than salmon, though with salmon a lot of the fat content is â€œhealthyâ€ types of fat that are actually good for the body. There is also more cholesterol in salmon than there is in tilapia, though there is still not a very significant amount in salmon.
There are many different nutritional/health benefits to eating both these kinds of fish, so you will want to seriously thing about including both of them in your diet. Salmon does however contain a little bit more potassium than tilapia, so it definitely has its nutritional benefits.
