The pescatarian diet is a vegetarian lifestyle with the addition of seafood. It is a largely plant-based diet of whole grains, nuts, legumes, produce, and healthy fats, with seafood playing a key role as a main protein source. The term pescatarian was coined in the early 1990s and is a combination of the Italian word for fish, pesce, and the word vegetarian. Pescatarians may also eat eggs and dairy, but they do not eat red meat or poultry. This diet is often chosen for health reasons, as it is associated with a lower risk of obesity, heart disease, high blood pressure, and chronic diseases like diabetes and cancer.

What You'll Learn
The pescatarian diet is largely plant-based
The pescatarian diet is a vegetarian lifestyle with the addition of seafood. It is largely plant-based, with fruits, vegetables, legumes, whole grains, nuts, and seeds forming the basis of the diet. This means that a pescatarian diet shares many of the benefits of vegetarianism, including a lower risk of obesity and chronic diseases like heart disease, high blood pressure, and diabetes. Research has shown that people who consume a diet high in vegetables and other plant foods have improved blood lipids and lower blood pressure.
The inclusion of seafood in the pescatarian diet is what sets it apart from a strictly vegetarian diet. Seafood is an excellent source of lean, complete protein. For example, a 5-ounce can of tuna in water contains 30 grams of protein and only 1 gram of saturated fat. In addition, about 90% of a can of tuna's calories come from protein. Fish, especially fatty fish like salmon, herring, and trout, are also concentrated in omega-3 fatty acids, which are essential to health and are involved in regulating inflammation in the body.
However, it is important to note that not all seafood is equally healthy. Some types of fish, like tuna, swordfish, and tilefish, have moderate to high levels of mercury, which can cause health problems, especially for babies and children. Therefore, it is recommended that young children and women of childbearing age or who are pregnant or breastfeeding mostly eat fish that is low in mercury, such as salmon, mackerel, herring, sardines, and lake trout.
In addition to seafood, some pescatarians also include other animal products in their diet, such as eggs and dairy. However, all pescatarians avoid red meat and poultry. This distinction from a strictly vegetarian diet provides additional flexibility and variety in meal options, which may be appealing to those considering a plant-based diet.

Pescatarians eat fish and seafood
The pescatarian diet is a vegetarian lifestyle with the addition of fish and seafood. It is a largely plant-based diet of whole grains, nuts, legumes, produce, and healthy fats, with seafood playing a key role as a main protein source.
Some types of fish, like tuna, swordfish, and tilefish, have moderate to high levels of mercury, which can cause health problems, especially for babies and children. So it is important to choose lower-mercury types of fish. Pescatarians can also include eggs and dairy products in their diet, although some choose not to.
The pescatarian diet has many potential health benefits. It can lower your risk of heart disease, high blood pressure, and stroke, and it may also protect against colorectal cancers. It can also help with weight management, as people who shift their diet in a more plant-based direction tend to gain less weight over time.
In addition to the health benefits, some people choose the pescatarian diet because they believe a meat-based diet is bad for the environment. They feel that land animals raised for food use too many natural resources and add to pollution.

It's a flexible diet
The pescatarian diet is a flexible one. It is largely a plant-based, vegetarian diet with the addition of fish and seafood. The term "pescatarian" is a combination of the Italian word for fish, "pesce", and the word "vegetarian". This means that the diet includes fruits, vegetables, legumes, whole grains, nuts, seeds, beans, eggs, and dairy.
There are no strict rules about how much of each food group one should eat on a pescatarian diet. Instead, there is freedom and flexibility to choose which pescatarian-friendly foods to eat and in what quantity, based on one's preferences and health goals. For example, some pescatarians may eat eggs and dairy, while others may not.
The pescatarian diet is flexible in that it can be adapted to suit individual needs and preferences. It is a good option for those who want to reduce their meat consumption for health, environmental, or ethical reasons but who still want to include some animal products in their diet.
The diet can also be tailored to accommodate specific dietary restrictions or preferences. For example, those who are lactose intolerant or vegan can choose to exclude dairy products, while those with an egg allergy can avoid eggs.
In addition, the pescatarian diet can be adjusted to suit different budgets and accessibility needs. Fish and seafood can vary widely in price and availability depending on one's location and the specific type of seafood. However, it is important to note that some types of fish, such as tuna, swordfish, and tilefish, have moderate to high levels of mercury, which can cause health problems, especially for children and pregnant women. Therefore, it is recommended to choose lower-mercury types of fish, such as salmon, mackerel, herring, sardines, and lake trout.

It has many health benefits
The pescatarian diet has many health benefits. Firstly, it is a largely plant-based diet, and eating a variety of fruits and vegetables is associated with a lower risk of Type 2 diabetes and heart disease. Plant-based diets are also linked to a lower risk of obesity and chronic diseases.
Secondly, the pescatarian diet is heart-healthy. Research shows that eating fish regularly may help reduce the risk of heart attacks, high blood pressure, atherosclerosis, and stroke. This is because fish, especially fatty fish like salmon, herring, mackerel, and trout, are rich in omega-3 fatty acids, which are essential to health and are involved in regulating inflammation in the body.
Thirdly, the pescatarian diet may protect against certain types of cancer. Fruits and vegetables contain nutrients and phytochemicals that help fight the cell changes that can lead to cancer. In addition, one study showed that pescatarians live longer than people who eat red meat and poultry, and they had a lower risk of developing dementia, strokes, or Parkinson's disease in their later years.
Finally, the pescatarian diet can be a healthy way to support weight loss. Fish and eggs are great sources of lean protein, and plant-based proteins like soy, nuts, and legumes are healthy ways to get more of this important nutrient. Choosing lean proteins over high-fat meat can help with weight loss.

It's a lifestyle choice
Adopting a pescatarian diet is a lifestyle choice with a range of health and environmental benefits.
The pescatarian diet is a vegetarian lifestyle that includes seafood. It is a largely plant-based diet of whole grains, nuts, legumes, produce, and healthy fats, with seafood playing a key role as a main protein source.
Many people choose this lifestyle for the health benefits of a plant-based diet, plus the additional benefits of heart-healthy fish. Research shows that eating less red meat, or none at all, lowers your chances of getting heart disease, high blood pressure, and cancer. Fish is a good source of protein and, unlike red meat, is low in saturated fat and often rich in healthy omega-3 fatty acids.
Some people choose this lifestyle to curb the environmental impact of their diet. A meat-based diet is considered by some to be bad for the environment, with land animals raised for food using too many natural resources and adding to pollution. Pythagoras, Plato, and various monks throughout history are suspected or known to have eaten a pescatarian diet. Pythagoras may have chosen this diet because he believed that fish do not waste land space, are plentiful due to high reproduction rates, and can be captured and slaughtered in ways that inflict minimal pain.
It is important to note that a pescatarian diet does not automatically mean a person will cut calories or eat healthily. Processed foods like potato chips and sugary cereals are technically allowed, and any diet can be unhealthy if it includes too many of these foods. To make the most of the pescatarian lifestyle, focus on whole foods like fruits, vegetables, nuts, seeds, and whole grains. It is also important to be mindful of the levels of mercury in fish, as some types of fish have moderate to high levels, which can cause health problems.
