Your Guide to Pescatarian Diets for Living Healthier

With 2022 quickly approaching you may be thinking of changing up your diet. If a healthier you is on the to-do list for next year, you might consider the pescatarian diet. At its core, the pescatarian diet eliminates all meat except for fish and seafood. There’s plenty of research out there that eating red meat increases your chances of heart disease and even death by 3% to 7%. The study even suggests that eating poultry twice a week increases these risks by 4%.

You may have heard of the Blue Zone Diet. If you’re not familiar, Blue Zones are areas around the world where people live the longest, healthiest lives. The research was conducted by Dan Buettner, a National Geographic fellow, and best-selling author. These zones are located in Japan, Italy, Costa Rica, Greece, and California. There are a number of practices you can put in place to follow the Blue Zone Diet if you wish. However, for our purposes, it’s simply important to note that the people living the longest and healthiest lives were neither vegans nor meat-eaters. They’re pescatarians.

What is a Pescatarian Diet?

Pescatarians live somewhere in the middle of vegetarians and meat-eaters. While they do not consume any beef, pork, or poultry, they do eat seafood like fish and shellfish. Aside from those protein sources, you can really fill your pescatarian diet with whatever you’d like. Fruit, vegetables, grain, corn, beans, the options are endless. What’s great about the pescatarian diet is that you can follow a number of other diet plans while still being a pescatarian.

If you’re into the Keto Diet, fatty fish like salmon and tuna will work great with your diet. You can still consume the other foods you were eating as part of the Keto diet.

If Whole 30 is your thing, no problem. Just work some fish into your meals and skip the other meat.

If you’re on the Intermittent Fasting train, more power to ya. When you do eventually eat something, just make sure it comes from the ocean, not the farm.

It’s really that easy to adapt to a pescatarian diet, and there are tons of benefits to doing so.

Benefits of Pescatarian Diet

Healthline outlines the benefits of eliminating other types of meat from your diet.

  • Benefits include, “a lower risk of obesity and chronic diseases like heart disease and diabetes.”
  • Less weight gain and, if paired with the correct nutrition plan, the possibility of weight loss.
  • A lower environmental impact, since raising animals for food takes a lot of resources.

There are also a number of ethical reasons for not eating meat, including the treatment and slaughter of animals.

Drawbacks of Pescatarian Diet

  • Low in iron. Be sure to consume plenty of iron-rich veggies like spinach and broccoli.
  • Fish contains mercury. Mackerel, shark, swordfish, and tuna all contain mercury. These fish are also some of the most overfished, however, so you should try to avoid them, anyway. Fish Wise is one group helping consumers make more responsible fish buying choices.
  • Cost. No doubt, fish can be kind of expensive. An ethically sourced piece of salmon will cost more than a chicken breast. It is suggested that fish should only be consumed in 3 oz portions, though, so while more expensive consider it a treat. Also, because you’ve cut the chicken and steak out of your diet (meat is more expensive than vegetables) you’ll likely be able to keep the grocery bill pretty flat if you switch to only eating fish.

This recipe from The Mediterranean Dish is super easy. The whole meal is roasted in the oven and only uses one pan.



  • Zest of 2 lemons
  • Juice of 2 lemons
  • 1 cup Private Reserve Greek extra virgin olive oil
  • 1 ½ tablespoons freshly minced garlic
  • 2 teaspoons dill weed
  • 1 teaspoon seasoned salt, more for later
  • ½ teaspoon ground black pepper
  • 1 teaspoon dried oregano
  • ½ to ¾ teaspoon ground coriander

For the Fish

  • 1 pound fresh green beans
  • 1 pound cherry tomatoes
  • 1 large yellow onion sliced into half-moons
  • 1 ½ pound halibut fillet, sliced into 1 ½-inch pieces


  1. Preheat the oven to 425 degrees F.
  2. In a large mixing bowl, whisk the sauce ingredients together. Add the green beans, tomatoes, and onions and toss to coat with the sauce. With a large slotted spoon or spatula, transfer the vegetables to a large baking sheet (21 by 15 by 1-inch baking sheet, for example). Keep the vegetables to one side or one half of the baking sheet and make sure they are spread out in one layer.
  3. Now, add the halibut fillet strips to the remaining sauce, toss to coat. Transfer the halibut fillet to the baking sheet next to the vegetables and pour any remaining sauce on top.
  4. Lightly sprinkle the halibut and vegetables with a little more seasoned salt.
  5. Bake in 425 degrees F heated oven for 15 minutes. Then transfer the baking sheet to the top oven rack and broil for another 3 minutes or so, watching carefully. The cherry tomatoes should begin to pop under the broiler.
  6. When ready, remove the baked halibut and vegetables from the oven. Serve with your favorite grain, Lebanese rice, or pasta.

These 9 foods will boost immunity naturally with zinc
Zinc is a crucial part of a healthy immune system. Get your fix with these foods
Meat and poultry served on a chopping board.

When most people focus on eating well, they focus on the overall diet and large macronutrients like protein, fat, and carbohydrates. However, depending on the foods you gravitate toward and how varied your diet is, it’s still quite possible to have deficiencies in certain micronutrients—the key vitamins and minerals your body needs for optimal health and function—such as zinc.

Zinc deficiencies are particularly common in vegans and vegetarians, but many people would benefit from increasing their dietary intake of this immune-supportive mineral. As an essential mineral, zinc must be consumed through the diet because the body cannot manufacture it endogenously. Moreover, zinc is a necessary component of over 300 enzymes in the body. It is heavily involved in immune support, wound healing, building DNA and biological proteins, smell, taste, and fertility. Foods high in zinc, such as oysters, are also great foods to help prevent hair loss, as zinc plays a key role in protein production and hair follicle cell differentiation.
