The paleo diet, designed to emulate the eating habits of our Paleolithic ancestors, has gained popularity for its potential health benefits. Simultaneously, pescetarianism, a plant-based diet supplemented with fish and seafood, attracts individuals seeking a balanced and ethical approach to eating. Combining these two dietary approaches results in the paleo-pescatarian diet, a unique eating plan with its own set of considerations.
Understanding the Paleo Diet
A paleo diet is an eating plan based on foods humans might have eaten during the Paleolithic Era - approximately 2.5 million to 10,000 years ago. The paleo diet plan includes unprocessed meats, fish, eggs, vegetables, fruits, nuts, seeds, herbs, spices, nutritious fats, and oils. It excludes foods that became more common when small-scale farming began about 10,000 years ago. The purpose of a paleo diet is to eat foods likely eaten by early humans. Farming made foods such as grains and legumes more easily available. And it introduced dairy. Also, farming changed the diets of animals that people ate. The paleo diet idea is that these changes in diet outpaced the human body's ability to change or adapt.
The modern paleo diet emphasizes whole, unprocessed foods, mirroring the presumed diet of hunter-gatherers. By following a diet of whole foods and leading physically active lives, hunter-gatherers presumably had much lower rates of lifestyle diseases, such as obesity, diabetes, and heart disease.
Foods to Include
The paleo diet encourages the consumption of:
- Meat: Beef, lamb, chicken, turkey, pork, and others. Grass-fed options are often preferred.
- Fish and seafood: Salmon, trout, haddock, shrimp, shellfish, etc. Wild-caught is ideal.
- Eggs: Free-range, pastured, or omega-3 enriched.
- Vegetables: Broccoli, kale, peppers, onions, carrots, tomatoes, etc.
- Fruits: Apples, bananas, oranges, pears, avocados, strawberries, blueberries, and more.
- Tubers: Potatoes, sweet potatoes, yams, turnips, etc.
- Nuts and seeds: Almonds, macadamia nuts, walnuts, hazelnuts, sunflower seeds, pumpkin seeds, and more.
- Healthy fats and oils: Extra virgin olive oil, avocado oil, and others.
- Salt and spices: Sea salt, garlic, turmeric, rosemary, etc.
Foods to Avoid
The paleo diet discourages the consumption of certain foods, including:

- Sugar and high-fructose corn syrup: Soft drinks, fruit juices, table sugar, candy, pastries, ice cream, and many others.
- Grains: Bread, pasta, wheat, cereal, spelt, rye, barley, etc.
- Legumes: Beans, lentils, and many more.
- Dairy: Most dairy, especially low-fat dairy (some versions of paleo do include full-fat dairy like butter and cheese).
- Some vegetable oils: Soybean oil, sunflower oil, cottonseed oil, corn oil, grapeseed oil, safflower oil, and others.
- Artificial sweeteners: Aspartame, sucralose, cyclamates, saccharin, acesulfame potassium (use natural sweeteners instead).
- Highly processed foods: Everything labeled “diet” or “low fat” or that has many additives, including artificial meal replacements.
Embracing Pescetarianism
A Pescetarian diet excludes all types of animal flesh and meat, with one exception: fish. Some people make the choice to follow a Pescetarian for health reasons, while others make these dietary choices because of religious or moral reasons. A pescatarian meal plan is mainly a vegetarian or plant-based diet wherein participants get their protein supply from fish and fish products. It is known as one of the branches of a vegetarian diet.
Key Components of a Pescetarian Diet:
- Fish and Seafood: The primary source of protein, offering omega-3 fatty acids and other essential nutrients.
- Vegetables and Fruits: A wide variety of colorful produce for vitamins, minerals, and fiber.
- Legumes: Beans, lentils, and peas provide plant-based protein and fiber.
- Whole Grains: Brown rice, quinoa, and oats offer complex carbohydrates and nutrients.
- Nuts and Seeds: Healthy fats, protein, and various micronutrients.
- Dairy and Eggs: Many pescetarians include dairy and eggs in their diet, though this is a matter of personal preference.
Potential Benefits
- Heart Health: Fish are among the healthiest and most nutritious foods on the planet and are the primary protein source on the pescatarian meal plan. Eating fish is very beneficial because you will be able to get the omega-3 fatty acids that are needed for optimal health. These fatty acids reduce the risk of cardiovascular diseases such as heart attacks and stroke. They also boost body, eye, and brain function.
- Weight Management: A pescatarian meal plan for a weight-loss plan must be meticulously planned with a focus on limiting the amount you eat related to calorie deficiency and exercising. You should reduce your caloric intake to between 3500 to 7000 calories a week for gradual and sustainable weight loss. An energy deficit diet works even better when you eat the right kind of healthy meals.
- Nutrient Rich: Fish are not only high in protein and iodine, but they also have vitamin D, something that most people lack.
- Reduced Risk of Chronic Diseases: Pescetarian and ketogenic diets are known for their many health benefits, such as a reduced risk of obesity, type 2 diabetes, and heart disease.
Navigating the Paleo-Pescatarian Intersection
Combining the paleo and pescetarian diets requires careful consideration. The core principle involves adhering to paleo guidelines while sourcing protein primarily from fish and seafood.
Acceptable Foods
- Fish and Seafood: All types of fish and seafood are allowed, with an emphasis on wild-caught varieties when possible.
- Vegetables and Fruits: A wide array of non-starchy vegetables and fruits.
- Nuts and Seeds: A variety of nuts and seeds, excluding peanuts (which are legumes).
- Healthy Fats: Olive oil, avocado oil, coconut oil, and other paleo-approved fats.
- Eggs: Some paleo-pescetarian diets include eggs, but this is optional.
Foods to Avoid
- Grains: All grains, including wheat, rice, corn, oats, and barley, are excluded.
- Legumes: Beans, lentils, peas, and peanuts are not permitted.
- Dairy: Most dairy products are avoided, although some individuals may choose to include grass-fed butter or ghee.
- Processed Foods: Any processed foods, including those with added sugars, artificial sweeteners, or unhealthy fats.
Nutritional Considerations and Potential Deficiencies
If you compare the overall nutritional consumption of a Pescetarian Paleo diet compared with a traditional Paleo lifestyle, you will see that there are several nutrients that you might be missing. These nutrients aren’t necessarily unavailable, but you need to take a proactive approach to make sure that you are getting the nutrition that is needed.
- Conjugated Linoleic Acid: A certain type of saturated fat that is readily available in grass-fed meat. It is possible to get this nutrient from grass-fed butter or pastured eggs.
Looking closely at the common theme with the 3 nutrients listed above, you will see that there is one important element that needs to be included in a Pescetarian diet: grass-fed, pasture raised butter and/or eggs. Make sure that you are using high quality eggs and butter, because the conventionally produced ingredients don’t have the same nutrients available.
Addressing Potential Deficiencies
- Omega-3 Fatty Acids: Consume fatty fish like salmon, mackerel, and sardines regularly. Consider a fish oil or algal oil supplement if necessary.
- Vitamin D: While fish provides some vitamin D, supplementation may be necessary, especially during winter months or for those with limited sun exposure.
- Calcium: If dairy is excluded, prioritize calcium-rich foods like leafy green vegetables, and consider a calcium supplement.
- Iron: Include iron-rich fish and seafood, and pair them with vitamin C-rich foods to enhance absorption.
