Being a pescetarian essentially means following a primarily vegetarian diet with the addition of fish and other seafood.
In simpler terms, you avoid land-based meats (like chicken, beef, and pork), but include fish, shellfish, and other aquatic options (like crab, mussels, and oysters) in your meals.
Here are some key points about pescetarianism:
- Plant-based focus: Most of the pescatarian diet comes from fruits, vegetables, whole grains, nuts, seeds, beans, and legumes. These provide essential nutrients, fiber, and antioxidants.
- Seafood as protein source: Fish and seafood act as the primary source of protein in this diet. They are rich in omega-3 fatty acids, which are good for heart health and brain function.
- Variations: Some pescatarians include eggs and dairy in their diets, while others avoid them completely. It ultimately depends on personal preferences and ethical considerations.
- Reasons for choice: People choose pescetarianism for various reasons, including health benefits, environmental concerns, ethical considerations regarding animal welfare, or simply personal taste.
The pescatarian diet, which includes fish and seafood but excludes other meats, offers a multitude of benefits for both your body and the planet. Here are 10 reasons why going pescatarian might be a good choice for you:
1. Boosts heart health:
Fish is rich in omega-3 fatty acids, particularly EPA and DHA, which have been shown to lower blood pressure, reduce inflammation, and prevent blood clots. This translates to a decreased risk of heart disease, stroke, and sudden cardiac death.
2. Reduces cancer risk:
Studies suggest that a pescatarian diet may lower the risk of certain cancers, including colorectal, prostate, and breast cancer. This is likely due to the combined effects of omega-3s, antioxidants, and fiber found in fish and plant-based foods.
3. Supports brain health:
Omega-3s are essential for brain development and function. They may help protect against cognitive decline, Alzheimer’s disease, and depression.
4. Promotes healthy weight management:
Pescatarian diets tend to be lower in calories and saturated fat than meat-based diets, while still being rich in protein and fiber. This can help you feel fuller for longer and prevent overeating.
5. Improves gut health:
The pescatarian diet is naturally high in fiber, which is essential for gut health. It promotes the growth of good bacteria in the gut, which can improve digestion, boost immunity, and even reduce the risk of colon cancer.
6. Provides essential nutrients:
Fish is a good source of vitamin D, iodine, selenium, and other essential nutrients that are often lacking in vegetarian and vegan diets.
7. More sustainable than meat-based diets:
Fish production has a lower environmental impact than meat production. Choosing sustainable seafood options can further reduce your environmental footprint.
8. Easier to transition than vegetarianism or veganism:
If you’re not ready to give up meat entirely, pescetarianism can be a good stepping stone towards a more plant-based diet.
9. Offers variety and taste:
There are endless possibilities when it comes to cooking pescatarian meals. You can enjoy fish in various ways, from grilled and baked to poached and stewed. Plus, seafood pairs well with a wide variety of fruits, vegetables, and grains.
10. May improve mental health:
Some studies suggest that a pescatarian diet may be linked to a lower risk of depression and anxiety. This may be due to the omega-3s in fish, which are known to have mood-boosting effects.
Overall, the pescatarian diet is a healthy and sustainable way to eat that offers a multitude of benefits for both your physical and mental health. If you’re considering making a change to your diet, pescetarianism is definitely worth exploring.
It’s important to note that while the pescatarian diet offers many benefits, it’s still important to choose healthy seafood options and to limit your intake of mercury-laden fish. Talk to your doctor or a registered dietitian for personalized advice on how to follow a pescatarian diet in a healthy and sustainable way.

What is the scientific take on the pescatarian diet
The scientific take on the pescatarian diet is largely positive, highlighting its potential benefits for both individual health and environmental sustainability. While research is ongoing, several key findings support its advantages:
Health benefits of pescatarian diet
- Cardiovascular health:
- Fish, particularly fatty fish, is rich in omega-3 fatty acids, especially EPA and DHA, which have shown to reduce inflammation, blood pressure, and risk of blood clots. A 2019 study in the New England Journal of Medicine found that substituting seafood for some red meat was associated with a lower risk of major cardiovascular events.
- A 2017 review in Nutrients concluded that pescatarians had a lower incidence of coronary heart disease compared to omnivores.
- Cancer risk:
- Studies suggest a link between pescetarianism and a decreased risk of certain cancers, including colorectal, prostate, and breast cancer. This may be due to the combined effects of omega-3s, antioxidants, and fiber found in fish and plant-based foods.
- A 2017 analysis in Nutrients reported that pescatarians had a 22% lower risk of colorectal cancer compared to those who rarely or never consumed fish or seafood.
- Brain health:
- Omega-3s are crucial for brain development and function, potentially delaying cognitive decline and Alzheimer’s disease. A 2015 study in the American Journal of Clinical Nutrition found that older adults who consumed fish regularly had slower cognitive decline compared to those who didn’t.
- Weight management:
- Pescatarian diets tend to be lower in calories and saturated fat than meat-based diets, while still being rich in protein and fiber. This can help with satiety and potentially aid weight management. A 2017 study in the journal Obesity found that women who were pescatarians gained less weight over time than those who ate meat.
- Gut health:
- The high fiber content in plant-based foods benefits gut health, improving digestion, immunity, and reducing colon cancer risk. A 2018 review in the journal Nature Reviews Gastroenterology & Hepatology highlighted the importance of dietary fiber for maintaining a healthy gut microbiome.
- Mental health:
- Some studies suggest a link between pescetarianism and lower risks of depression and anxiety, attributed to mood-boosting effects of omega-3s. A 2019 review in the journal Current Psychiatry Reports found evidence suggesting that omega-3 fatty acids may have antidepressant effects.
Environmental impact:
- Compared to meat production, fish production generally has a lower environmental footprint in terms of greenhouse gas emissions, land use, and water consumption. Choosing sustainable seafood options further reduces this impact. A 2015 study in the journal Nature Communications concluded that replacing land-based meat with seafood could significantly reduce the environmental impact of food production.
It’s important to note:
- The health benefits of a pescatarian diet depend on the quality and types of fish consumed. Limiting mercury-laden fish and choosing sustainable options is crucial.
- Individual needs and preferences should be considered when designing a pescatarian diet. Consultation with a registered dietitian can help personalize the approach for optimal health.
