7 Pescatarian Benefits

  1. Provides omega-3 fatty acids
  2. Helps lower inflammation
  3. Promotes heart health
  4. May help protect against cancer
  5. Fights cognitive decline
  6. Boosts mood
  7. Supports weight loss

1. Provides Omega-3 Fatty Acids

One of the primary reasons fish is so good for us is because of its high levels of omega-3 fatty acids. In a world where most people consume far too many omega-6s from refined vegetable oils, salad dressings and processed condiments, an increase in omega-3 foods is much needed.

Omega-3s act as a counterbalance against omega-6 fats, helping to keep inflammation low by balancing levels of omega-3 and omega-6 fatty acids. Omega-3 fatty acids are considered anti-inflammatory, while omega-6s are pro-inflammatory. We need both types, but many people are lacking in omega-3s. Consuming higher levels of omega-3s has been associated with better mental health, lower triglyceride levels, improved reproductive health and fertility, better hormone control and a lower risk for diabetes.

2. Helps Lower Inflammation

The reason that the omega-3s found in fish are so valuable mostly comes down to their ability to fight inflammation. They help control inflammatory conditions that lead to numerous diseases, including cancer, rheumatoid arthritis and asthma.

Both types of polyunsaturated fats described above play an important role in the body, helping to form our hormones, cell membranes and immune responses. But omega-3 and omega-6 fatty acids have opposite effects when it comes to inflammation. Generally speaking, too much omega-6 and too little omega-3 causes inflammation. Inflammation is thought to contribute to the development of chronic conditions such as cancer, diabetes, heart disease and more.

3. Promotes Heart Health

EPA and DHA are two omega-3 fatty acids that are essential for controlling inflammation and promoting heart health. Studies show that daily consumption of EPA and DHA may help reduce heart disease risk and deaths from heart disease, sometimes just as effectively as prescription medications like statins. The combination of nutrients found in seafood also helps regulate heartbeats, reduce blood pressure and cholesterol levels, decrease blood clot formation and lower triglycerides, all of which can help protect against heart disease and stroke.

4. May Help Protect Against Cancer

Research shows that consuming more fish and seafood high in omega-3s benefits the immune system and helps fight cancer by suppressing inflammation. In fact, while vegetarian diets are linked to a lower incidence of certain cancers (like colon cancer), pescatarianism is actually associated with an even lower risk compared to vegetarians and non-vegetarians alike, according to some studies.

Several studies also suggest that consuming plenty of omega-3 fatty acids can help those who have already been diagnosed with cancer by stalling tumor growth. Following a pescatarian lifestyle high in omega-3s can also help people undergoing chemotherapy or other cancer treatments since they help preserve muscle mass and regulate inflammatory responses, which are already compromised in those with cancer.

5. Fights Cognitive Decline

Omega-3s like DHA are essential for the proper development of the brain and preservation of cognitive function as we get older. Many studies have found that low omega-3 levels in the elderly are associated with multiple markers of impaired brain function, including dementia or Alzheimer’s disease. Lower levels of omega-3s during pregnancy are even associated with children having lower memory test scores and learning difficulties.

6. Boosts Mood

Because they fight oxidative stress that impairs proper brain functioning, the omega-3s from fish and seafood are associated with better mental health and a lower risk for dementia, depression, anxiety and ADHD. That means following a pescatarian diet could be a natural remedy for anxiety and may help treat the symptoms of ADHD while warding off symptoms of depression.

7. Supports Weight Loss

Many people have started using the pescatarian diet for weight loss, and for good reason. Low intakes of omega-3s have been tied to obesity and weight gain. Studies also show that people who eat more plant foods (including vegetarians) tend to have lower BMIs and better weight control, likely because they eat more fiber and less calories.

Not only that, but healthy proteins and fats are crucial for feeling full, and many of the nutrients found in fish can help reduce cravings. No matter your diet, aim for a high intake of fruits, vegetables, quality proteins, healthy fats, seeds, nuts, fiber and phytochemicals — all of which can help you lose weight fast and keep it off.

Drawbacks to a Pescatarian Diet?

Like all types of diets — from pescatarian, to keto and beyond — restricting certain food groups can lead to issues. It’s possible to start feeling deprived when consuming only pescatarian meals because meat and most animal products become “off limits.” It’s also possible to become bored with eating fish, eggs, dairy and plant foods each day in order to obtain enough protein, potentially leading to an increased intake of carbohydrates instead. This poses its own risks for potential weight gain, protein deficiency, fatigue and other health problems.

Another thing to consider when following a pescatarian diet is your intake of mercury. Mercury is, in fact, toxic, but its toxic effects are somewhat mitigated by the mineral selenium, which is present in nearly all wild-caught seafood. However, considering the level of toxins found in today’s oceans, mercury toxicity is a real concern, so it’s best to also focus on eating smaller fish and limit your consumption of high-mercury fish, such as king mackerel, tilefish, swordfish and shark.

Adding variety to your diet and planning out your meals can be a useful tool to ensure success on the pescatarian diet. Crafting a well-rounded, balanced pescatarian breakfast, lunch and dinner each day can also help you fit a wide array of fruits, veggies, healthy fats and protein foods into your diet to squeeze plenty of nutrients into your day. Additionally, practicing pescatarian meal prep and experimenting with different pescatarian recipes can also maximize the nutritional value of your diet.

Final Thoughts

  • The pescatarian diet is a type of diet that typically includes fish and seafood but excludes meat or poultry.
  • There are numerous variations for the pescatarian diet. Some may include poultry, while others may restrict other animal products, like eggs, dairy or honey.
  • In addition to the potential ethical and environmental benefits of the pescatarian diet, there are several health benefits associated with the diet as well.
  • Some of the pescatarian benefits include reduced inflammation, improved heart health, enhanced cognitive function, increased weight loss, improved mood and a lower risk of cancer.
  • However, it’s important to plan your diet carefully and steer clear of high-mercury varieties of fish to ensure you’re meeting your nutritional needs and prevent adverse side effects.
