A pescatarian diet is one where your main source of protein is fish and other aquatic animals such as shrimp. There are no strict rules around being a pescatarian, so you may find some who also include eggs and dairy in their diets.
Pescatarians tend to have a healthy diet which is predominantly plant-based. Fish protein is high in omegas, making it perfect for heart health and joints.
If prepared by grilling or baking, fish is also relatively low in calories, so is perfect for managing your weight. Because you have a wide variety of fish and shellfish to choose from, pescatarian diets are versatile and less restrictive than many other diets.
On the down side, pescatarians may need to take iron supplements to keep their iron levels up as they are not eating red meat.
For those who do not eat dairy or cheese, they may also be lacking calcium, phosphorus and B12. Fish eaters should also avoid fish that are high in mercury.
