Pescatarian Diet 2026
When it comes to diets, there’s plenty of fish in the sea. But if you’re looking for an eating pattern that touts all the benefits of a vegetarian diet, without swearing off sushi, look no further than the pescatarian diet.
The pescatarian diet eliminates red meat and poultry but embraces fish and other seafood. This diet is regarded as one of the highest quality diets, and it's rich in nutrients.
What is the pescatarian diet? The word ‘pescatarian' is a blend of the Italian words for fish, “pesce,” and the term “vegetarian”, and the diet is a healthy, delicious marriage of both worlds. It’s a plant-based diet of fruits, vegetables, whole grains, nuts, seeds and legumes that incorporates protein solely from fish and seafood. Some pescatarians may eat eggs and dairy, while others may not.
“It’s more flexible than a vegetarian or vegan diet in that it allows more variety in being able to get protein in your diet,” says Rebecca Purcell, a registered dietitian nutritionist at Yale University in New Haven, Connecticut, adding that eating should be pleasurable. “You should enjoy eating the foods that you’re nourishing your body with and have the flexibility too.”
While the pescatarian diet’s etymology stems in part from a vegetarian diet, health experts liken it more to the Mediterranean diet – without the meat. The Mediterranean diet is a plant-based approach inspired by the eating habits of people in countries near the Mediterranean Sea – including Greece, Italy, Spain and France. It emphasizes whole grains, fruits, vegetables, beans, herbs, spices, nuts, seeds and healthy fats from extra-virgin olive oil, as well as fish and seafood. However, unlike the pescatarian diet, the Mediterranean diet allows moderate to limited amounts of poultry and red meat.
The Mediterranean diet consistently ranks #1 in The U.S. News’ Best Diets Overall for good reason: Researchers have repeatedly shown that this eating plan offers a plethora of health benefits, from lowering blood pressure, improving "good" cholesterol levels, reducing Type 2 diabetes risk and boosting cognitive function to protecting against age-related diseases – to name a few.
Given the strong evidence behind the Mediterranean diet, it's no wonder health experts also highly recommend a plant-forward diet with fish.
“The focus on fish and seafood as the only animal product utilized in the pescatarian diet helps to greatly reduce the saturated fat consumption but also adds the benefits of being healthy,” explains Mary Ellen DiPaola, a registered dietitian at the University of California, San Francisco. “A diet based on plant foods and fish and seafood is beneficial
to all as it is nutrient-dense, can reduce disease risk, reduces the carbon footprint, and is delicious.”
