Tuna is a popular seafood that is consumed worldwide. It is rich in protein, vitamins, and minerals, making it a healthy addition to a balanced diet.
However, consuming too much tuna can also have negative effects on your health. In this article, we will discuss what happens if you eat too much tuna.

Mercury Poisoning
One of the primary concerns associated with consuming too much tuna is mercury poisoning. Mercury is a naturally occurring element that can be found in seafood, including tuna.
When humans consume too much mercury, it can accumulate in the body and cause mercury poisoning, which can have serious health effects.
Symptoms of mercury poisoning include numbness, tingling in the fingers and toes, tremors, difficulty thinking and concentrating, and memory problems. In severe cases, it can lead to permanent nerve damage, kidney damage, and even death.
High Levels Of Sodium
Tuna that is canned in water or brine can be high in sodium. Consuming too much sodium can lead to high blood pressure, which is a risk factor for heart disease, stroke, and kidney disease.
It is recommended that adults consume no more than 2,300 milligrams of sodium per day, or even less if you have high blood pressure.
To reduce the risk of consuming too much sodium from tuna, opt for tuna that is canned in water rather than oil or brine, and rinse it thoroughly before consuming.
Effect On Ecosystem
Overfishing of tuna can lead to a decline in tuna populations and can also harm other marine species. Tuna are often caught using methods that can also harm dolphins, sharks, and sea turtles, which can negatively impact the ecosystem.
To reduce the impact of tuna fishing on the environment, choose tuna that has been caught using sustainable fishing methods, such as pole and line or troll fishing.
While tuna is a healthy food option, consuming too much tuna can have negative health effects. It is important to consume tuna in moderation and choose sustainably caught tuna whenever possible.
If you are concerned about the potential risks of consuming too much tuna, speak with your healthcare provider or a registered dietitian for guidance on how to incorporate tuna into your diet safely.
Ideal Consumption
Tuna is a nutritious and healthy food option that is rich in protein, vitamins, and minerals. However, consuming too much tuna can also have negative health effects due to the potential accumulation of mercury and high levels of sodium in some tuna products.
To ensure that you are getting the benefits of tuna while minimizing the risks, here are some guidelines for ideal consumption:
- Adults should aim to consume no more than two to three servings of tuna per week. A serving size is typically 3-4 ounces (85-113 grams) of cooked tuna.
- Children and pregnant women are advised to consume even less tuna, as mercury can be particularly harmful to developing fetuses and young children. Children should consume no more than one serving of tuna per week, and pregnant women should limit their consumption to two servings per month.
- It is important to choose tuna that has been caught using sustainable fishing methods, such as pole and line or troll fishing, to reduce the impact of tuna fishing on the environment.
- When consuming canned tuna, choose tuna that is canned in water rather than oil or brine, and rinse it thoroughly before consuming to reduce the amount of sodium.
- It is also recommended to vary your seafood choices to include a variety of different fish, such as salmon, trout, and sardines, which are also rich in omega-3 fatty acids and other nutrients.
By following these guidelines for ideal consumption, you can enjoy the health benefits of tuna while minimizing the potential risks of consuming too much.
Health Benefits Of Eating Tuna In Moderation
Tuna is a nutritious and healthy food that provides numerous health benefits. Here are some of the potential health benefits of eating tuna:

- Provides Essential Nutrients: Tuna is a good source of several essential nutrients, including vitamin D, niacin, phosphorus, and potassium. These nutrients play important roles in maintaining overall health and wellbeing.
It is important to note that consuming too much tuna can also have negative health effects due to potential mercury and sodium content. It is recommended to consume tuna in moderation and choose sustainable and low-sodium options whenever possible.
