The pescatarian diet, or pescatarianism, is a primarily vegetarian diet that includes fish and other seafood. The term pescatarian was coined in the late 1980s to early 1990s and is a combination of the Italian word for fish, pesce, and the word vegetarian. While the modern term is relatively new, the diet itself dates back centuries, with some evidence suggesting that Greek philosopher Pythagoras and his followers may have been pescatarians. The pescatarian diet has gained popularity in recent years due to its potential health and environmental benefits.

What You'll Learn
The term 'pescatarian' was coined in the 1980s or 1990s
The term "pescatarian" is a neologism formed as a portmanteau of the Italian word "pesce" ("fish") and the English word "vegetarian". The term was coined in the United Kingdom in the late 1980s or early 1990s. The diet, however, has been around for much longer. For example, in the 13th century, Cistercian monks consumed fish, eggs, and cheese.
The term ""pesco-vegetarian"" is synonymous with "pescatarian" and has appeared in American publications and literature since at least 1980, although it is seldom used outside of academic research. The first vegetarians in written Western history may have been the Pythagoreans, a title derived from the Greek philosopher Pythagoras. Some biographers suspect that Pythagoras himself may have been a pescatarian, as he is known to have eaten fish in addition to a meatless diet.
In medieval Europe, several orders of monks restricted or banned the consumption of meat for ascetic reasons, but none of them abstained from fish. These monks were not vegetarians, but some were pescatarians. For example, the Marcionites considered fish to be a holier kind of food and consumed bread, fish, honey, milk, and vegetables.
In the 19th century, Francis William Newman, who was President of the Vegetarian Society from 1873 to 1883, made associate membership possible for people who were not completely vegetarian, such as pescatarians. Newman himself eventually switched from an ovo-lacto-vegetarian diet to a pescatarian diet in the 1890s.

Health benefits of the pescatarian diet
The term "pescatarian" was coined in the early 1990s by combining the Italian word for fish, "pesce," with "vegetarian." It refers to a diet that primarily consists of vegetarian dishes with the addition of fish and other seafood. Some pescatarians may also include eggs and dairy in their diet.
Now, let's dive into the health benefits of the pescatarian diet:
Improved Cardiovascular Health
The pescatarian diet is ideal for optimising cardiovascular health. This is mainly due to the inclusion of fish, which is an excellent source of omega-3 fatty acids, specifically EPA and DHA. These essential fats are linked to improved heart and blood vessel health, a reduced risk of high blood pressure, and a decreased likelihood of blood clots and sudden cardiac death. Research suggests that regularly consuming fish may help lower the risk of heart attacks, atherosclerosis, and stroke. Additionally, the plant-based aspect of the pescatarian diet contributes to improved blood lipids and lower blood pressure, further enhancing cardiovascular health.
Lower Risk of Chronic Diseases
Following a pescatarian diet can help lower the risk of various chronic diseases. Plant-based foods, which are a significant component of the pescatarian diet, are associated with a reduced risk of obesity. Additionally, the combination of plant-based foods and fish in the pescatarian diet may provide protective benefits against chronic diseases like heart disease and diabetes. Research indicates that pescatarians have a lower risk of developing diabetes compared to omnivores.
Potential Protection Against Certain Cancers
The pescatarian diet may offer some protection against colorectal cancers. A 2017 analysis found that a pescatarian diet had a strong protective effect against cancers affecting the colon and rectum. This protective effect may be attributed to the high intake of plant-based foods and the potential nutrition gaps filled by adding fish to a vegetarian diet.
Brain Health Benefits
The omega-3 fatty acids abundant in fish may provide benefits for brain health. Studies suggest that consuming fish at least twice a week is associated with a lower risk of developing vascular brain diseases, such as stroke. Additionally, the long-term Seventh-Day Adventist Study reported that pescatarians had a lower risk of developing dementia or Parkinson's disease later in life compared to strict vegetarians.
Environmental Benefits
While not a direct health benefit, it is worth noting that the pescatarian diet has a lower environmental impact than diets that include meat. Choosing fish over meat or poultry reduces greenhouse gas emissions, although the sustainability of this depends on how the fish is caught and the management of fisheries, as some species are overfished.
While the pescatarian diet offers these health benefits, it is important to be mindful of potential pitfalls. These include the risk of mercury consumption from certain types of fish, possible nutrient deficiencies, and the inclusion of unhealthy, highly processed foods. It is always advisable to consult with a healthcare professional or registered dietitian before making significant dietary changes.

Environmental impact of the pescatarian diet
The term "pescatarian" was coined in the early 1990s and refers to a person who follows a primarily vegetarian diet that includes fish and seafood. The diet is largely plant-based and consists of whole grains, nuts, legumes, produce, and healthy fats, with seafood playing a key role as a main source of protein.
Now, let's discuss the environmental impact of the pescatarian diet:
The pescatarian diet is often considered a more environmentally friendly alternative to an omnivorous diet that includes meat. This is because meat production, particularly livestock farming, contributes significantly to climate change and carbon emissions. According to the United Nations, raising livestock accounts for 15% of all human-made carbon emissions. In contrast, the production of fish and seafood generally has a lower carbon footprint than producing animal meat or cheese. A 2014 study found that diets of fish eaters caused 46% less greenhouse gas emissions than diets that included meat.
However, it is important to note that the environmental impact of the pescatarian diet depends on the type of fish consumed and the fishing practices involved. For example, overfishing is a significant issue, and certain fishing methods, such as trawler fishing, can damage entire marine ecosystems. Additionally, fishing can lead to bycatch and the deaths of sea animals, which raises ethical concerns.
Farmed fish, such as oysters, can be more sustainable than wild-caught fish, but it is important to consider the environmental impact of fish farming as well, including the use of freshwater and the issue of eutrophication. The environmental impact of the pescatarian diet also depends on the amount of fish consumed and the frequency of seafood in one's diet.
Overall, while the pescatarian diet may be a more sustainable option than an omnivorous diet, it is not without its environmental challenges. To make more environmentally conscious choices, it is recommended to consider the specific types of fish consumed, the fishing practices involved, and the frequency of seafood in one's diet.

Historical pescatarians
The term "pescatarian" was coined in the late 1980s or early 1990s, but the diet itself has likely been around for much longer. While there is no specific information about historical pescatarians, we can look at the reasons why people choose this diet to understand who might have eaten this way in the past.
The main reasons people choose a pescatarian diet today are for the purported health benefits and as an ethical alternative to a meat-heavy diet. A diet heavy in red meat and poultry is associated with higher rates of heart disease, diabetes, and some cancers, as well as a shorter lifespan. The pescatarian diet is largely plant-based, which has been linked to a lower risk of obesity and chronic diseases. The addition of fish and seafood provides omega-3 fatty acids, protein, and other nutrients that may be missing from a strict vegetarian diet.
The environmental impact of meat production is also a significant factor. According to the United Nations, raising livestock contributes to 15% of all human-made carbon emissions. Pescatarians may choose to include fish in their diet instead of meat as it has a lower carbon footprint and generates fewer greenhouse gas emissions.
Ethical concerns about slaughtering animals, inhumane factory farming practices, and the unjust use of land and resources for producing grain for animal feed are also reasons why people may choose a pescatarian diet.
While there is no direct evidence of historical pescatarians, it is possible that people in the past chose to eat this way for similar health, environmental, and ethical reasons. For example, ancient Greeks and Romans are known to have valued physical fitness and a healthy diet, so they may have been drawn to the health benefits of a pescatarian diet. Additionally, certain religious groups, such as early Christians and some Buddhist sects, have promoted vegetarianism or semi-vegetarianism for ethical reasons, so they may have also been early adopters of a pescatarian diet.
