There is some debate as to whether fish can be included in a plant-based diet. Some sources claim that a plant-based diet can include moderate amounts of meat, poultry, fish, and seafood, while others argue that a plant-based diet traditionally includes no animal products. Fish are rich in omega-3 fatty acids, which have anti-inflammatory properties and are essential fats that our bodies cannot produce on their own. However, fish also contain harmful substances such as saturated fat, cholesterol, polychlorinated biphenyls (PCBs), dioxins, and mercury, which can negatively affect human health. Ultimately, the decision to include fish in a plant-based diet may depend on individual preferences and interpretations of what constitutes a plant-based diet.

What You'll Learn
Fish is not plant-based
While a plant-based diet can be flexible, it is generally understood to be a diet that focuses primarily on plants and is abundant in nutrient-dense foods like fruits, vegetables, nuts, seeds, whole grains, and legumes. A plant-based diet is not necessarily a vegetarian diet, but it also does not include meat, poultry, fish, seafood, eggs, and dairy.
Fish is an animal product, and therefore does not fall within the definition of a plant-based diet.
Some people may choose to adopt a “plant predominant” or “plant-focused” diet, which allows for small amounts of animal products, including fish. However, it is important to note that this is not a purely plant-based diet.
Fish consumption also has several potential health risks, including high levels of saturated fat and cholesterol, as well as contaminants and pollutants such as mercury, polychlorinated biphenyls (PCBs), and dioxins. These substances can have adverse effects on human health, including neurological damage, liver and skin damage, and increased risk of cancer and heart disease.
In conclusion, while fish may be a source of omega-3 fatty acids, it is not a plant-based food. A plant-based diet focuses on plant-derived foods and excludes or limits animal products, including fish.

Pescatarians eat fish, not meat
The term "pescatarian" refers to someone who follows a plant-based diet that includes fish and seafood. While the term is a combination of the Italian word for fish, "pesce," and the word "vegetarian", it is important to note that fish are not plants. Therefore, including fish in a plant-based diet would technically make it no longer plant-based.
That being said, some people who follow a plant-based diet may choose to include small amounts of fish, perhaps once a week or periodically. This could be considered a "Mediterranean" or "plant-predominant" diet rather than a strictly plant-based one. The benefits of including fish in one's diet include an increased intake of omega-3 fatty acids, lean protein, and other essential nutrients. Fish is also believed to have positive effects on heart health, with research showing that regular consumption may reduce the risk of heart attacks, high blood pressure, atherosclerosis, and stroke.
However, there are also drawbacks to including fish in one's diet. Fish can contain high levels of mercury and other toxins, which can be harmful to human health. Additionally, the fishing industry has a significant environmental impact, with bottom trawling emitting similar levels of greenhouse gases as the aviation industry.
Ultimately, the decision to include fish in one's diet is a personal one, and there is no definitive answer as to whether it is "OK" from a plant-based perspective. Those who choose to include fish may do so for taste preferences, health reasons, or because they believe it is a more feasible option than a fully plant-based or vegan diet. However, it is important to be mindful of the potential risks and impacts associated with fish consumption.

Fish is rich in omega-3 fatty acids
Fish is often associated with health benefits, and it is true that fish is a good source of omega-3 fatty acids. Omega-3 fatty acids are beneficial for your body and brain and can help lower inflammation and reduce the risk of heart disease and stroke.
Fatty fish, such as salmon, mackerel, sardines, anchovies, and herring, are particularly rich sources of omega-3s. For example, a 3.5-ounce serving of mackerel provides 4,580 mg of omega-3s, while the same serving size of salmon contains 2,150 mg. The American Heart Association recommends eating at least two servings of fatty fish per week to promote heart health.
However, it is important to note that omega-3 fatty acids are also found in several plant-based sources, including flaxseed, chia seeds, walnuts, and soybeans. These plant-based sources provide the omega-3 fat alpha-linolenic acid (ALA), which the body may not use as efficiently as the omega-3s found in fish. Nonetheless, a plant-based diet can provide adequate amounts of omega-3s without the need for fish.
In addition, while fish may provide omega-3s, it also has several drawbacks as a food source. Fish contains higher levels of essential amino acids, which can lead to increased production of the hormone IGF-1, associated with cancer proliferation. Fish is also a source of cholesterol and saturated fats, which can increase the risk of cardiovascular disease. Furthermore, fish is commonly contaminated with heavy metals, such as mercury, and industrial pollutants, which can have toxic effects on the body.
Therefore, while fish is rich in omega-3 fatty acids, it is not the only source of these beneficial fats, and there are valid health concerns associated with consuming fish. A plant-based diet can provide sufficient omega-3s through a variety of whole foods, nuts, and seeds, promoting health without the potential risks associated with fish consumption.

Fish is high in cholesterol and saturated fat
Fish is generally considered a healthy protein option for people with high cholesterol. However, it is important to note that fish does contain cholesterol and saturated fat, which are associated with an increased risk of cardiovascular disease.
While fish is often recommended as a source of lean protein for those with high cholesterol, it is important to consider the type of fish and the method of preparation. Fish that are high in omega-3 fatty acids, such as salmon, trout, and tuna, are considered to be heart-healthy and can help lower triglyceride levels. However, fish that are deep-fried or cooked in butter can add unnecessary saturated fats to the meal, counteracting some of the health benefits.
In addition to the cholesterol and saturated fat content, fish may also contain contaminants and pollutants such as mercury, industrial byproducts, and pesticides. These toxins can have negative effects on health, including neurologic disturbances and increased risk of cancer.
When it comes to managing cholesterol levels, it is recommended to focus on reducing saturated and trans fats, as well as increasing the consumption of vegetables, fruits, whole grains, nuts, and legumes. While fish can be a part of a heart-healthy diet, it should be consumed in moderation and prepared in a healthy way.
Overall, while fish does contain some cholesterol and saturated fat, it can still be a healthier option compared to other animal proteins when consumed in moderation and prepared in a healthy way. However, it is important to consider the potential risks associated with contaminants and pollutants in fish and prioritize plant-based sources of omega-3 fatty acids whenever possible.

Fish is often contaminated with heavy metals and toxins
Heavy metals, such as mercury, arsenic, cadmium, and lead, are the most common contaminants found in fish. These metals are released into aquatic environments through natural processes and human industrial activities. Mercury, for example, is introduced into the water through industrial waste, smokestack emissions, and coal-powered factories. Fish absorb these metals through their gills and skin, leading to bioaccumulation, primarily in the liver and kidney tissues.
The consumption of contaminated fish can result in the accumulation of heavy metals in the human body, causing various health issues. Mercury, a neurotoxic heavy metal, can cause a wide range of neurologic disturbances and affect normal cardiac physiology. It can also cross the placenta barrier, posing risks to the developing fetus. Other heavy metals, such as cadmium and lead, have been linked to kidney damage, bone loss, hypertension, and cancer. Long-term exposure to heavy metals has been associated with physical and muscular disorders, as well as diseases such as Alzheimer's, Parkinson's, and multiple sclerosis.
To address this issue, comprehensive monitoring, regulation, and remediation efforts are necessary. Public awareness campaigns and the establishment of dietary guidelines are crucial in minimizing the health risks associated with the consumption of contaminated fish. Additionally, environmental legislation, holistic planning, and technological measures to improve waste management are recommended strategies to combat this problem.
