The carnivore diet is a restrictive diet that includes animal-based foods like meat, fish, and other animal products. The diet eliminates all plant-based foods, including fruits, vegetables, legumes, grains, nuts, and seeds. Fish is a part of the carnivore diet and is considered a good source of protein and omega-3s. However, there are concerns about the high mercury content in certain types of fish, such as old, large, and carnivorous fish. The diet is promoted as a way to lose weight, improve health, and treat various conditions, but there is limited research to support these claims, and it may not be suitable for everyone.

What You'll Learn

Fish is allowed on a carnivore diet
Fish is an excellent source of protein and omega-3 fatty acids, which are essential for a healthy diet. Salmon, trout, oysters, clams, sardines, anchovies, halibut, cod, shrimp, and grouper are all fish and seafood options that can be included in a carnivore diet.
Some people on a carnivore diet may choose to base their meals primarily around fish and seafood. This can be a healthy choice, as the Japanese diet includes a large amount of seafood and is associated with positive health outcomes. However, it is important to be aware of the potential for mercury poisoning from certain types of fish, especially older, larger, and carnivorous fish, as well as those from certain regions like the Mediterranean Sea.
There are many recipes available for including fish in a carnivore diet, such as fish tacos, coconut lime fish soup, trout with garlic lemon butter herb sauce, and honey garlic-glazed salmon.
It is worth noting that the carnivore diet is controversial and may not be suitable for everyone. It is important to consult a healthcare professional before starting any new diet, especially one as restrictive as the carnivore diet.

Mercury in fish
Fish is included in the carnivore diet, which is a restrictive diet that only includes meat, fish, and other animal foods like eggs and certain dairy products. The diet stems from the belief that ancestral populations ate mostly meat and fish and that high-carb diets are responsible for today's high rates of chronic disease.
Mercury is a naturally occurring element found in the air, water, and food. Fish absorb methyl mercury from streams and oceans as they feed. This mercury is in the more toxic, methylmercury form, which binds to proteins in the body, such as those found in muscle tissue. Fish efficiently absorb methyl mercury and excrete it very slowly, leading to a buildup of mercury in their tissues over time. This process is known as bioaccumulation and results in higher concentrations of mercury in predatory fish and birds that are higher on the food chain.
Species of fish that are long-lived and high on the food chain, such as marlin, tuna, shark, swordfish, king mackerel, and tilefish, contain higher concentrations of mercury. The consumption of fish is the most significant source of ingestion-related mercury exposure in humans and animals. Mercury from coal-burning power plants and chlorine production plants is a major contributor to the high mercury levels found in fish.
Pregnant women, women planning pregnancy, and young children are particularly vulnerable to the effects of mercury, and it is recommended that they avoid or limit the consumption of fish with high mercury levels. High mercury levels in pregnant women can impact the development of the unborn baby, particularly the nervous system. Research has shown that mercury levels in some shark species caught in Victorian waters are particularly high.
It is important to monitor fish advisories and choose fish that are lower in mercury content. The FDA and EPA have issued advice and guidelines to help pregnant and breastfeeding women, as well as parents and caregivers, make informed choices about the types of fish that are safe and nutritious to consume.

Fish as a healthy foundation
Fish is an excellent foundation for a healthy carnivore diet. The Japanese, for example, consume a lot more seafood and have better health outcomes. Fish is a good source of protein and omega-3s, and there are many recipes available online for zero-carb seafood dishes.
The carnivore diet is a restrictive diet that includes meat, fish, and other animal foods like eggs and certain dairy products. It excludes all other foods, including fruits, vegetables, legumes, grains, nuts, and seeds. Its proponents argue that it can aid weight loss and help with health issues like depression, anxiety, arthritis, obesity, and diabetes. However, there is no reliable research to support these claims. The diet is high in fat, contains no fiber or beneficial plant compounds, and is difficult to maintain long term.
Fish like salmon, trout, sardines, anchovies, halibut, cod, grouper, and shrimp are all part of the carnivore diet. It is important to be mindful of the mercury content in fish, with older, larger, and carnivorous fish tending to have higher levels of mercury. Farmed fish, particularly tilapia from Vietnam, and salmon with artificial colouring, should be avoided.
The coastal Inuit, who traditionally had a fish-heavy diet, also consumed whale and seal blubber, as well as fatty meat. While the carnivore diet can be a good way to increase muscle and bone density, it is important to be cautious of potential nutrient deficiencies and health risks associated with the diet's restrictiveness.
