Function

People adopt a pescetarian lifestyle as a way to transition into becoming a vegetarian, or to eat a healthier, more environmentally-friendly diet.
Benefits
-
A diet rich in fish helps a person get plenty of omega-3 fatty acids, which aid in cardiovascular health, decreased triglyceride levels, and lower blood pressure.
-
Additional Benefits
-
By omitting meat from your diet, you keep saturated fat to a minimum, which helps keep you thin and minimize chances of cardiovascular disease.
Considerations
-
In order to ensure that you get the most omega-3 fatty acids, you need to eat fatty fish, including salmon, albacore tuna, mackerel, and sardines.
Warning
-
One must consider the risk of high mercury intake with a fish-only diet. This is fairly manageable if you stick with wild salmon, and avoid shark, swordfish, king mackerel, and tilefish.
