Fish and seafood are not considered vegetarian, but some people may choose to incorporate them into their plant-based diets for a variety of reasons. Those who follow a primarily plant-based diet but occasionally consume fish and seafood are known as pescatarians. People may choose to transition to a pescatarian diet for the nutritional benefits of fish, such as its high content of omega-3 fatty acids, protein, zinc, and vitamin B12. It can be challenging for strict vegetarians to obtain these nutrients from their diets. Additionally, some people may opt for a pescatarian diet to add more variety to their meals.

Fish and seafood are rich sources of protein, vitamins, and minerals
Fish and seafood are highly nutritious, offering a wide range of health benefits. They are an excellent source of lean protein, with cod providing 63 grams of protein per 100 grams, which is significantly higher than chicken or tofu. Fish is also a great source of omega-3 fatty acids, which are essential for maintaining a healthy heart and brain. These omega-3 fatty acids include EPA and DHA, which are found in varying amounts in seafood. Additionally, fish is rich in vitamins and minerals, including vitamin D, vitamin B2 (riboflavin), calcium, phosphorus, iron, zinc, iodine, magnesium, and potassium.
The American Heart Association recommends consuming fish at least twice a week for a healthy diet. Eating seafood twice a week can help lower blood pressure and reduce the risk of heart disease, heart attack, and stroke. Fish is also a good source of vitamin A, which is vital for red blood cell production, eye health, and overall wellness. Salmon, for example, contains vitamin A in its flesh, while fish liver is particularly rich in it.
Seafood is also an excellent source of B vitamins, which help build tissue and form red blood cells, and vitamin E, which is an antioxidant that protects our bodies from free radicals. Clams, oysters, mussels, fish eggs, octopus, and fish like sardines, salmon, herring, and mackerel are high in vitamins B-12 and B-6, crucial for brain function. Additionally, seafood is a good source of minerals like iron, phosphorus, potassium, and zinc, which support overall health and well-being.
For those looking to introduce fish into their vegetarian diet, there are a few recommended options. Some people suggest starting with fish that has a mild flavour and is less "fishy," such as tilapia or pollock, which are commonly used in fish sandwiches or sticks. Sushi is another popular gateway to eating fish, as it often masks the fishy taste with rice and other ingredients. Seabass, salmon, and tuna are also suggested as introductory fish, with various recipes available online.

Omega-3 fatty acids are abundant in fish and have many health benefits
Omega-3 fatty acids are essential nutrients that we have to obtain from our diet. They are abundant in fish and have many health benefits.
There are three types of omega-3 fatty acids: EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), and ALA (alpha-linolenic acid). EPA and DHA are marine omega-3 fatty acids found in fish, while ALA is a plant-based omega-3 fatty acid. However, the body can only convert a small amount of ALA into EPA and DHA, so dietary sources of these two fatty acids, such as fish, are essential.
EPA fatty acids aid in lowering blood triglyceride levels, preventing clogging of blood vessels and reducing irregular heartbeats, which are all risk factors for heart disease and stroke. DHA fatty acids, on the other hand, play a crucial role in brain and eye development and help strengthen and protect brain function, learning, memory, and the visual system.
The health benefits of omega-3 fatty acids are extensive. They help lower blood pressure, reduce inflammation, and improve cardiovascular health. Additionally, omega-3 fatty acids may help lower the risk of developing some forms of cancer, Alzheimer's disease, dementia, and age-related macular degeneration. Research also suggests that consuming omega-3 fatty acids at 850 mg/day, in combination with natural vitamin E, can reduce the risk of strokes and heart failure.
The American Heart Association recommends that individuals without a history of heart disease consume at least two servings of fish per week, totalling 6 to 8 ounces. For those with heart disease or high triglyceride levels, consuming even more omega-3 fatty acids may be beneficial, but it is essential to consult a healthcare provider to determine the appropriate amount.

Some fish types are less fishy and may be better for those new to eating it
If you are new to eating fish, you may want to start with fish types that are less fishy in taste. Most white fish, such as tilapia, halibut, grouper, cod, and pollock, are considered mild in flavour and are, therefore, a good starting point. Tilapia, in particular, is extremely common and is often used in fish sandwiches and other seafood dishes. It is also generally sustainably caught, although it may contain drugs and chemicals if sourced from China.
Swordfish is another option with a mild taste and a firm texture. Similarly, Alaskan pollock has a slightly higher oil content but still boasts a mild flavour. Rockfish is a white fish with a slightly nuttier flavour that works well with a variety of marinades and flavour combinations.
Mahi-mahi is a fish with a semi-mild flavour, often paired with tropical fruits like mango and pineapple, or savoury sides like red beans and rice. Salmon is also a nutritious option, but it has a strong flavour and is considered one of the "fishiest" fishes, especially when raw. If you are looking for a salmon-based dish, it is recommended to bake it in a pouch of aluminium foil with some lemon and salt.
For those who want to try anchovies, consider recipes that cook them down into the fat of the dish, which adds umami flavour without a fishy taste. Sardines, on the other hand, are less intense in flavour than anchovies but still have a "fishy" and salty taste. They can be paired with olive oil, mayo, or aioli to lighten their flavour.

Vegetarians who eat fish are called pescatarians
People may adopt a pescatarian diet for several reasons. One reason is the health benefits associated with plant-based diets, such as a lower risk of obesity and chronic diseases like heart disease and diabetes. Research shows that a pescatarian diet can also provide these protective benefits. For example, a study found that women who were pescatarians gained 2.5 fewer pounds each year than women who ate meat. Additionally, fish is a good source of lean protein, omega-3 fats, and other nutrients.
Ethics can also play a role in the decision to become a pescatarian. Some people may choose to eliminate land animals from their diet due to concerns about inhumane factory farming practices, poor labor conditions, and the environmental impact of their diet. While aquaculture and overfishing can be problematic, choosing fish that are caught or farmed in ethical and sustainable ways can address some of these concerns.
Introducing fish into a vegetarian diet can be challenging for those who are not used to the taste. Some people may find it helpful to start with fish that are less "fishy," such as tilapia or pollock, which are commonly used in fish sandwiches and frozen fish sticks. Sushi and sashimi are also recommended as a way to explore different types of fish and find what you like. When cooking fish, methods such as baking, grilling, or sautéing are generally healthier than deep-frying.
It is important to consider the nutritional value and potential negatives of different types of seafood, such as the way it is caught or prepared. For example, some fish, such as salmon, are high in nutrition but can give off a strong fishy smell during cooking. It is also recommended to choose lower-mercury types of fish, especially for women of childbearing age or who are pregnant or breastfeeding.

Marinating fish can reduce its fishy smell and taste
If you're a vegetarian looking to incorporate fish into your diet, you may be concerned about the strong fishy smell and taste that fish can sometimes have. One effective way to mitigate this is by marinating the fish before cooking it.
Marinating fish in vinegar, for example, is a well-known technique to reduce its fishy odour and taste. The high acidity level of vinegar neutralises the smell and taste by making the compounds in the fish bind with water instead of amino acids, resulting in a less intense flavour. Similarly, lemon juice can also be used to neutralise the odour, although it will leave the fish with a citrusy flavour.
Another option is to soak the fish in milk before cooking it. The protein in milk binds with the compounds that cause the fishy odour, effectively extracting it from the fish. This technique, recommended by Cook's Science, leaves the fish with a sweeter-smelling and brighter flesh.
Additionally, removing the skin from white-fleshed fish like tilapia and cod can help reduce the fishiness as the natural oils in the skin can contribute to a stronger taste. Oily fish like salmon and mackerel, for instance, tend to have a stronger smell than these white-fleshed alternatives.
When introducing fish into a vegetarian diet, it's also worth considering the type of fish you choose. Some fish, like tilapia and pollock, are known for being less "fishy" in taste and are commonly used in fish sandwiches or frozen fish sticks. Starting with milder-tasting fish and working your way up may be a good strategy to acclimate to the new flavours.
Overall, by using these marinating techniques and choosing the right type of fish, you can effectively reduce the fishy smell and taste, making it a more pleasant experience as you introduce fish into your vegetarian diet.
