The pescetarian diet is a vegetarian diet that includes fish and other seafood. There are no strict guidelines on how often one must eat fish to be considered pescetarian. Most pescetarians eat eggs and dairy, although some do not. People who are lactose intolerant do not need to follow a pescetarian diet, as it is possible to be both lactose intolerant and pescetarian. However, those who are lactose intolerant and choose to follow a pescetarian diet should be mindful of the dairy they consume.

Pescetarian diet definition
The pescetarian diet, sometimes spelled 'pescatarian', is a vegetarian diet that includes fish or other aquatic animals. 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 "pescetarian" 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.
Pescetarians do not eat meat, including poultry, game, or red meat, but they do eat fish and seafood. Some pescetarians also eat dairy and eggs, while others do not. Those who eat eggs and dairy are called lacto-ovo-pescetarians. There are no strict guidelines to determine what is pescetarian versus what is vegetarian, outside of eating seafood. There are also no rules to define how often one must eat fish to be considered pescetarian.
The pescetarian diet is associated with several health benefits. Fish is a good source of protein and is often rich in healthy omega-3 fatty acids, which are important for heart, brain, and eye health. Studies have shown that eating less red meat or no red meat at all lowers one's chances of getting heart disease, high blood pressure, and cancer. A large study found that pescetarians have a lower risk of developing diabetes and a lower overall risk of cancer compared to meat-eaters. Pescetarian diets are also associated with a lower environmental impact, as meat production contributes to deforestation and greenhouse gas emissions.

Health benefits
It is not necessary for lactose-intolerant people to follow a pescatarian diet. However, a pescatarian diet can be a healthy option for those who are lactose intolerant as it is primarily plant-based and does not include meat or meat products.
A pescatarian diet is a vegetarian diet that includes fish and other seafood. It is a largely plant-based diet of whole grains, nuts, legumes, fruits, vegetables, and healthy fats, with seafood playing a key role as a main protein source. Many pescatarians also include dairy and eggs in their diet, but this is not necessary.
There are several health benefits to following a pescatarian diet, including:
- A good source of omega-3 fatty acids: Many types of fish are high in omega-3 fatty acids, which are important for heart health, brain health, and eye health. Research suggests that people who eat fish at least twice a week may have a lower risk of developing vascular brain diseases, such as stroke, compared to those who eat little or no fish.
- Lower risk of cancer: A large study found that pescatarians and vegetarians have a lower risk of cancer overall than meat-eaters, and a lower risk of colorectal and prostate cancer in particular. This is likely due to the avoidance of red meat, which is linked to cancer, and the higher intake of fruits and vegetables, which contain nutrients and phytochemicals that help fight changes in cells that can lead to cancer.
- Increased longevity: The Seventh-Day Adventist Study reported that while people who followed any kind of vegetarian diet tended to live longer than meat-eaters, pescatarians had an even greater longevity boost. This may be due to the additional health benefits of including seafood in the diet, such as the omega-3 fatty acids mentioned above.
- Improved cardiovascular health: The oils typically used in a pescatarian diet, such as olive oil, sesame oil, walnut oil, and canola oil, are good sources of monounsaturated and polyunsaturated fats, which contribute to cardiovascular health.
- Environmental benefits: While not directly related to individual health, the environmental impact of meat production, including deforestation and greenhouse gas emissions, is significant. Choosing fish over meat or poultry can help reduce these impacts, although it is important to consider the sustainability of how the fish is caught and the management of fisheries.

Dairy alternatives
There are several alternatives to dairy milk, such as soy, rice, oat, almond, hazelnut, coconut, quinoa, and potato drinks. Almond milk is a popular alternative as it is easy to make, cheap to buy, and has a mild flavor compared to other plant-based milks. Soy milk is often recommended by doctors for people with lactose intolerance, as it provides almost as much protein as whole milk. Coconut milk is also popular, especially in coffee, due to its creamy texture. Rice milk is sweeter and more watery than other options but can be a great replacement for milk in cereal.
There are also dairy-free alternatives to butter, such as coconut oil, olive oil, and avocados. Coconut oil can be used as a 1:1 replacement for butter in most recipes, while olive oil is better suited for sautéing and caramelizing rather than baking. Avocados are very versatile and can be used as a butter replacement in baking, depending on the recipe.
Soft cheese alternatives are easy to find, as there are many plant-based versions of soft cream cheese made with soy or coconut milk. These can also be made at home by blending soaked cashews with nut milk and lemon juice. Hard cheese alternatives are more challenging to make at home, but there are many store-bought options available.
Yogurt is also available in dairy-free options, made from sources like soy, oat, or coconut. These come in various flavors, from classic to thick, Greek-style yogurts.

Nutritional deficiencies
A pescetarian diet is primarily plant-based and includes a variety of whole grains, nuts, legumes, fruits, and vegetables. This dietary pattern provides a good source of fiber and various vitamins, minerals, and phytochemicals. Additionally, the inclusion of seafood in the pescetarian diet offers several nutritional benefits that may help mitigate potential deficiencies associated with lactose intolerance.
Seafood, including fish, crustaceans, and mollusks, is a rich source of omega-3 fatty acids, which are important for heart health, brain health, and eye health. The long-chain omega-3 fatty acids found in seafood, such as salmon and tuna, are particularly beneficial and may not be as readily available from plant sources. Therefore, including seafood in the diet can help ensure adequate intake of these essential fatty acids, which may be beneficial for individuals with lactose intolerance who are limiting their dairy intake.
In addition to omega-3 fatty acids, seafood also provides high-quality protein and other essential nutrients like vitamins B12 and D, zinc, and calcium. These nutrients may be of particular importance for individuals with lactose intolerance, as dairy products are typically a significant source of these nutrients in the diet. By including a variety of seafood options, pescetarians can help meet their nutritional needs and potentially avoid deficiencies that could arise from limiting dairy consumption.
While a well-planned pescetarian diet can provide many nutritional benefits, it is important to be mindful of potential deficiencies. Vitamin B12, for example, is mainly found in animal-based foods, so pescetarians who limit their seafood intake may need to pay particular attention to this nutrient. Additionally, while plant-based sources of omega-3 fatty acids exist, the body may not convert these as efficiently as the forms found in seafood. Therefore, including a variety of seafood options and considering supplements under medical supervision can help ensure adequate intake.
