In this review, I'll explain what the pescatarian diet is, how it works, what foods you can eat, the benefits and downsides, who might enjoy it, and what research says about it. By the end, you'll know if the pescatarian diet fits your lifestyle and goals.
What Is the Pescatarian Diet?
The pescatarian diet means eating fish and seafood but no other meat. People who follow it eat plenty of vegetables, fruits, grains, legumes, nuts, and seeds. But unlike vegetarians, pescatarians add fish and seafood to their meals.
This diet is not strictly vegetarian or vegan because it includes animal protein from fish. However, it is more plant-focused than diets that include meat like chicken or beef.
Some people choose pescatarianism for health reasons. Others pick it for ethical or environmental concerns, as fishing and seafood tend to have a smaller carbon footprint than raising land animals. It's also seen as a flexible way to cut back on meat without giving it up completely.
How Does the Pescatarian Diet Work?
The pescatarian diet works by encouraging mostly whole, natural foods. You eat lots of plants - vegetables, fruits, whole grains, beans, nuts, and seeds - which provide fiber, vitamins, and minerals. Then, you add fish and seafood as the main protein sources.
You avoid meat like beef, pork, chicken, and turkey. Dairy and eggs are usually allowed but in moderation, depending on your personal choice.
The diet supports balanced meals with healthy fats, lean protein, and carbohydrates from plants. Fish gives you important nutrients like omega-3 fatty acids, which support brain and heart health.
By focusing on fresh, unprocessed foods and cutting down on meat, many people find their digestion improves and they feel more energetic.
