Is it bad to eat tuna every day and what is the dosage?

According to Micharl Gochfeld, M.D., Ph.D., a researcher with the Environmental and Occupational Health Science Institute, this depends on each individual. For one individual it is likely to be safe to consume tuna fish every day, while for other individuals they could get poisoned by eating the same tuna fish.

Tuna is highly nutritious and contains protein, healthy fats, and vitamins – but should not be consumed daily.

The FDA recommends that adults eat 3/5 ounces (85-140 grams) of fish 2-3 times a week to obtain enough omega-3 fatty acids and other beneficial nutrients.

However, research shows that eating fish regularly with a mercury concentration of more than 0.3 ppm can increase mercury levels in the blood and spur health problems. Most tuna species exceed this number.

Therefore, most adults should eat enough tuna and consider choosing another fish that is relatively low in mercury.

When buying tuna, choose skipjack or canned mild varieties, which don’t contain as much mercury as albacore or large eyes.

You can consume canned skipjack and tuna along with other low-mercury species, such as cod, crab, salmon, and shellfish, as part of the recommended 2-3 servings of fish per week.

Try to avoid eating albacore or yellowfin tuna more than once a week. Avoid big-eyed tuna as much as possible.


Is it true that mercury in tuna contains toxins?

  • Sharks
  • Swordfish
  • Marlin fish
  • Tilapia

  • Muscles feel limp
  • Coordination of the limbs decreases
  • The sensory system is disturbed

How to Avoid the Dangers of Mercury Fish

The fact that there is potential for mercury in fish does not make you afraid to eat fish or shellfish. Fish is still a healthy food that you need to consume regularly.

If you accidentally consume fish containing mercury, the chemical will not immediately settle in your body but can be excreted through breast milk, urine, or feces.

However, the body, which is exposed to high levels of mercury, takes at least a year to be completely clean of these chemicals after fish consumption is stopped.

You can’t avoid mercury at all, because almost all fish and shellfish contain little mercury. Even so, to avoid the dangers of mercury fish, you are advised to start paying attention to the selection of the type of fish to be consumed and know the characteristics of the mercury fish.

Avoid or reduce the consumption of high levels of fish. Some types of fish are often used as the basic ingredients of sushi.

Instead, you are advised to consume fish with lower mercury content. Another important thing is to reduce or avoid eating raw fish, especially for pregnant women.
