Tuna, Mercury and Amalgam Dental Fillings
Lets look at tuna and mercury content compared to amalgam fillings.
Many dentists will tell you that eating tuna puts you at a great risk of mercury exposure than you dental amalgams. Is this correct?
Some quick facts for you about mercury and tuna:
- The Environmental Protection Agency (EPA) state that daily exposure to mercury should not exceed 0.1micrograms/kilogram of body weight/day
- This averages around 7ug per day
- A medium portion of salmon approx 200g contains 0.01ug of mercury
- The mercury content of tuna ranges from 0.06 – 0.3ug
- A person with 4 small amalgam fillings is exposed daily to an average of 7ug or more of mercury
- Therefore 1 small amalgam contains around 1.75ug of mercury – much more than your average can of tuna
- A person with 8 amalgam fillings daily exposure averages 12.5ug with 16% in this category showing levels of exposure up to 35 ug/day
- The average person with amalgams is exposed to an average of 10 ugs or more per day which exceeds the EPA standards
- 10 ug per day equates to a huge amount of salmon which has negligible mercury content!!!!
- However, if a person weighing approx 55kg consumes 3x200g of tuna per week they would be considered slightly over their recommended intake for mercury per day.
- So the bigger you are the more tuna you can eat!!! (In theory)
If you are concerned about your mercury levels or amalgam fillings then seek a consultation with a holistic dentist or integrative medicine doctor.
