If you eat more than the recommended amount, you can get mercury poisoning. Symptoms of mercury poisoning include loss of coordination, memory problems, numbness, pain, problems with vision, nausea and vomiting. Tuna is a good source of omega-3 fatty acids, which are important for brain and nervous system health.

How many canned of tuna can you eat a day?
Recommendations for healthy tuna consumption can be very different. According to some sources, eating more than a serving of tuna each week may put you at risk.
According to other sources, you would need to eat at least three cans of tuna a day for 6 months to get the recommended amount of omega 3s. Tuna is a good source of protein, which is important for maintaining a healthy weight.
Is there a limit to how much tuna you can eat?
Someone weighing 150 pounds should not eat more than a can of albacore tuna a week, according to the Centers for Disease Control and Prevention. CDC recommends that people who are pregnant, nursing, or planning to become pregnant avoid eating any fish containing mercury.
Can eating tuna everyday hurt you?
Some men could experience symptoms of mercury toxicity from eating the same amount of tuna, but it would be safe for many men to eat it every day. The study also found that men who ate the most tuna had the highest mercury levels in their blood, which is consistent with previous studies that have shown that mercury can accumulate in the body over time and cause damage to the central nervous system and kidneys, as well as to other organs, such as the heart and the brain.
Why you shouldn’t eat canned tuna?
The tuna sandwich is a staple in school. Several species of tuna contain higher-than-average amounts of mercury, a highly toxic metal that can cause damage to the brain and nervous system.
“Tuna is one of the most heavily contaminated fish in the world,” said Dr. David Schindler, an associate professor of environmental health sciences at the University of California, San Francisco, and a co-author of a study published this week in Environmental Health Perspectives.
How long does mercury from tuna stay in the body?
The mercury in these is lower down in the food chain. In humans, if mercury levels in the blood are found to be high, they can take up to 6 months or longer to return to normal. RDA is based on a person’s age, sex, height, weight, and body mass index (BMI).
For example, a 70-year-old man with a BMI of 25 would need a daily intake of 1,000 microg of methylmercury, which is about the same as the amount found in a can of tuna. If you are a woman, your daily dose would be slightly higher, at 2,500 micro grams, or about 1/3 of the daily recommended amount.
