I was boasting to my friends the other day about how i have switched to clean and healthy diet, and when I mentioned about can tuna. One of my friend who is working on food and additives company queried, "Isn't can tuna supposed to be unhealthy?!..it is highly processed!!" My question is, is it really considered unhealthy? The worrying thing is, I am eating it almost daily to help fulfill my protein requirements. *sigh* any comments on this.
