A pescatarian diet is an eating plan that removes all foods containing meat or poultry. Those who choose to be pescatarian do so for a variety of reasons. Some may choose to add fish to a vegetarian diet for the added heart-health benefits, while others may wish to minimize their environmental impact.

For the rest, it might be simply a matter of taste. Eating pescatarian may lead to improved health outcomes including a lower risk of obesity and chronic diseases like heart disease and diabetes.
