It may look thin and when in your mouth, the feeling is so light but prosciutto is very unhealthy. It has a lot of salt like the corned beef with around 973 mg per serving. (The RDA for sodium is 1500mg for three meals.) Moreover, 40% of its fat is the saturated content. So yeah, go to the other way and choose chicken, just to be safe. But you can indulge once in a while – meaning like one serving in one year.
