Plant-Based Diets: Do Fish Make The Cut?

Whether or not plant-based diets include fish is a highly debated topic. While some people argue that plant-based diets can include fish, others disagree and believe that a plant-based diet should only consist of plants and foods made from plants. Ultimately, it comes down to personal preference and beliefs. Some people may choose to include fish in their plant-based diet for health reasons, as fish is an excellent source of important nutrients such as protein, omega-3 fatty acids, vitamin B12, iodine, and selenium. On the other hand, vegans who follow a strict plant-based diet typically abstain from consuming any animal products, including fish, as they consider the production of these ingredients unethical, exploitative, or harmful to animal health.

Vegans don't eat fish

Veganism is a practice often adopted for health, environmental, ethical, or personal reasons. However, it can be challenging to determine which foods are permitted, as there are differing opinions about whether certain animal products can be included. For example, some plant-based diets may include certain types of fish, like bivalve mollusks (clams, mussels, oysters, and scallops), as these species lack a central nervous system and are believed to be unable to perceive pain. Nonetheless, this concept is controversial, as research suggests bivalves may possess complex nervous systems and could experience pain.

Ultimately, veganism excludes fish and other animal products due to ethical concerns about the production and consumption of these foods, which are considered harmful to animal health.

It is important to note that plant-based diets are not always vegan or vegetarian. While vegetarians generally abstain from eating meat, fish, and seafood, they may consume animal by-products like gelatin and dairy. Additionally, some plant-based diets, like the Mediterranean diet, include fish and poultry a few times a week. Therefore, when referring to plant-based diets, it is essential to understand the specific version being discussed, as there are many variations.

Some plant-based diets include fish

There is some debate about whether fish can be included in a plant-based diet. While veganism and vegetarianism exclude fish, some plant-based diets do include certain types of fish. Ultimately, it depends on personal preferences and beliefs.

Veganism and vegetarianism

Vegans and vegetarians typically do not eat fish. Veganism is a practice that involves abstaining from consuming animal products, including meat, poultry, fish, shellfish, honey, dairy products, and gelatin. Similarly, vegetarian diets exclude meat, poultry, and fish, although there are several subtypes of vegetarianism that allow for the consumption of certain animal products, such as dairy and eggs.

Plant-based diets

Plant-based diets focus on foods primarily from plants, including fruits, vegetables, nuts, seeds, whole grains, legumes, and beans. However, this does not mean that all plant-based diets are strictly vegetarian or vegan. For example, the Mediterranean diet, which is considered a plant-based diet, includes fish, poultry, eggs, cheese, and yogurt a few times a week, with meats and sweets consumed less often.

Pescatarian and ostrovegan diets

Some plant-based diets, such as the pescatarian and ostrovegan diets, do include certain types of fish. Pescatarians typically abstain from meat but include fish and seafood in their diets, along with dairy and eggs. Ostrovegans, on the other hand, follow a vegan diet that includes bivalve mollusks such as clams, mussels, oysters, and scallops. These organisms lack a central nervous system, which means they are unable to perceive pain in the same way as other animals. However, this concept is controversial, as some research suggests that bivalves may have more complex nervous systems and could experience pain.

Health benefits of including fish

Including fish in a plant-based diet can provide several health benefits. Fish is an excellent source of important nutrients, including protein, omega-3 fatty acids, vitamin B12, iodine, and selenium. Omega-3 fatty acids, in particular, are crucial for optimal brain health, heart health, and fetal development, and they are mostly found in oily fish. While plant sources of omega-3 fatty acids are available, evidence suggests that they may not have the same benefits in reducing the risk of heart disease as those found in fish.

Pescatarians eat fish

Plant-based diets focus on foods derived from plants, including fruits, vegetables, nuts, seeds, oils, whole grains, legumes, and beans. They are not necessarily vegetarian or vegan, and can include meat and dairy. However, people on plant-based diets tend to choose more of their foods from plant sources.

Pescatarians are people who follow a primarily vegetarian diet but also eat fish and seafood. They do not eat red meat or poultry. A pescatarian diet is largely plant-based and includes whole grains, nuts, legumes, produce, and healthy fats, with seafood playing a key role as a main protein source. Many pescatarians also eat eggs and dairy.

There are several reasons why people choose to be pescatarians. Some wish to gain the health benefits of a plant-based diet, plus the additional benefits of eating fish. Fish is an excellent source of important nutrients, including protein, omega-3 fatty acids, vitamin B12, iodine, and selenium. Omega-3 fatty acids, in particular, are known to have additional health benefits, helping not just the heart but also brain function and mood.

Others choose a pescatarian diet for environmental reasons. According to the United Nations, raising livestock contributes to 15% of all human-made carbon emissions. In contrast, producing fish and seafood has a lower carbon footprint than producing any type of animal meat or cheese.

Some people also have ethical reasons for choosing a pescatarian diet. They may oppose slaughter, refuse to support inhumane factory farming practices, or believe that producing grain for animal feed is an unjust use of land and resources when there is so much hunger in the world.

Fish is nutritious

The omega-3 fatty acids found in fish are crucial for optimal body and brain function and are strongly linked to a reduced risk of many diseases. They are also essential for growth and development, particularly for brain and eye development. For this reason, it is often recommended that pregnant and breastfeeding women consume enough omega-3 fatty acids by including fish in their diets.

In addition to omega-3 fatty acids, the high-quality protein in fish is an important nutrient that supports healthy muscles, organs, and blood vessels. Fish is also a good source of iodine, a vital mineral that the body cannot produce on its own. Iodine is important for thyroid function, which controls appetite and the immune system.

Fatty fish, such as salmon, trout, sardines, tuna, and mackerel, are especially nutritious due to their higher content of fat-based nutrients. These fish are excellent sources of vitamin D and omega-3 fatty acids. Eating fatty fish at least once or twice a week is recommended to meet your omega-3 requirements.

Overall, fish is a highly nutritious food that provides a wide range of health benefits. It is a great alternative to red meat and can be prepared in a variety of ways, making it easy to incorporate into your diet.

Fish is not vegan

Vegans do not eat fish. Veganism is a practice that involves abstaining from the use and consumption of all animal products. This includes meat, poultry, fish, and shellfish.

Fish are sentient beings

The sentience of fish is the second most important reason why vegans do not eat them. Sentience refers to the capacity of animals to have positive and negative experiences by processing information with their nervous systems. Over 99% of animal species are composed of sentient beings, and this includes fish. They have highly developed senses, including taste, touch, smell, hearing, and colour vision. They can move faster than humans and can react to the positive and negative experiences their brains create.

Fish feel pain

Like all other vertebrates, fish feel pain. There is plenty of scientific evidence to prove this. For example, in 2002, Dr Lynne Sneddon was the first scientist to prove conclusively that fishes have nociceptors (sensory receptors that detect potential harm and produce opioids that relieve suffering) in their mouths. Ashley et al. (2009) found that noxious stimulation affects anti-predator responses and dominance status in rainbow trout.

Fish are friends, not food

If you are a pescatarian, you may have ethical concerns about eating pigs, cows, chickens, or turtles but still eat salmon, sardines, cod, or tuna. However, if you observe different fishes in the wild, you will see that they live very similar lives to humans, preoccupied with mostly the same issues and reacting in the same ways.

Other reasons

There are many other reasons why vegans do not eat fish. These include:

• Health concerns: Many fishes often contain high levels of toxic contaminants such as mercury and PCBs that can be harmful to human health.
• Environmental concerns: Overfishing and unsustainable fishing practices harm marine ecosystems and biodiversity. About 2.8 trillion fishes are killed every year by humans.
• Social justice concerns: Labour practices in the fishing industry, resource depletion, and food justice are all issues that social justice vegans may consider.

There are many reasons why vegans do not eat fish, and no valid reasons to do so. If you are thinking of having the recommended long-chain Omega-3 fatty acids in your diet, you can get these from microalgae, not fish.
