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.

Jessica Gavin

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.

Treat your body: These are the best foods high in collagen
These are the tastiest foods for a boost of collagen, an important protein
Bowls of bone broth on a tray

Collagen has recently seemed to crop up in various supplements, whether they support athletic performance, help you get in some extra protein, or are essential for the beauty of your skin and hair. Foods with collagen help contribute to the structural components of bones, teeth, skin, ligaments, muscles, blood vessels, corneas, and connective tissue.
While you can take collagen supplements, collagen is also naturally present in certain foods, mainly of animal origin. The body can also synthesize collagen by combining the amino acids proline and glycine. This process requires vitamin C, zinc, and copper, so in addition to eating protein-rich foods, an adequate intake of these micronutrients will support your body’s endogenous production of collagen. Below, we share the foods highest in collagen to help you have healthy tissues, vibrant skin, mobile joints, and strong muscles.

Bone broth
Bone broth has become increasingly popular over the past decade. This nutritious stock is made by simmering the bones of animals, such as cows, chickens, fish, pigs, bison, and turkeys. Most of the time, connective tissues, such as hooves, beaks, and tendons, may also be used, which is what imparts this hearty stock with so much collagen. Bone broth may be used as a stock for other soups, consumed as a liquid broth as is, or turned into a health drink.
Though it may seem like simmered animal bones would not be all that nutritious, the extended boiling softens bones and cartilage and releases the vitamins and minerals within. The bones and connective tissue are rich in collagen, along with other minerals, including calcium, phosphorus, magnesium, potassium, and sulfur.
