If the level of  mercury in tuna is a problem then why are dentists using it in our teeth?

Expand canned tuna advisory, add labels: scientists

Health Canada’s new guidelines on eating canned albacore tuna may not go far enough, some scientists say.

Last week, the department issued the new consumption advice for women and children who eat the canned fish after a CBC investigation revealed mercury levels above the allowed limit in 13 per cent of 60 cans purchased in three Canadian cities.

Now, a Canadian woman has stepped forward saying she has suffered serious medical problems as a result of eating too much albacore tuna.

Maureen Hayes of Ottawa lost 60 pounds on a special diet that included eating up to four cans of albacore tuna a week for 10 years. About a year ago, she started having heart problems.

“I had heart palpitations,” Hayes said. “I had headaches every day, I had loss of memory, I was extremely fatigued, I had no energy, my skin was extremely dry and itchy, and then I started to develop allergies.”

It took one year, visits to several specialists and a magazine article about mercury before Hayes put the pieces together and had her blood tested. She discovered her blood had elevated levels of mercury.

Health Canada’s new guidelines on eating canned albacore tuna may not go far enough, some scientists say.

Last week, the department issued the new consumption advice for women and children who eat the canned fish after a CBC investigation revealed mercury levels above the allowed limit in 13 per cent of 60 cans purchased in three Canadian cities.

Troubling Tins

The new Health Canada guidelines say it is safe for pregnant women to consume nearly three cans of albacore tuna a week, slightly less than what Hayes was eating. In the U.S., the consumption guidelines range from one can a week to one can a month for pregnant women and children.

Hayes’ symptoms are consistent with long-term exposure to mercury, said Donna Mergler, a professor who specializes in mercury at the University of Quebec at Montreal.

Mergler was one of three experts CBC asked to review Hayes’ medical records. She said the federal government should extend its advisory to everyone, and put labels on cans of fish containing high levels of mercury.

“I don’t think the recommendations necessarily protect all the population, because as one can see, there are people that are particularly sensitive to it,” Mergler said.

Health Canada based its latest consumption advice for albacore tuna on a full scientific review of the latest data on toxic mercury levels in the fish, the department said in an e-mail to CBC.

Concerned E-mails

Hayes was one of about 70 people who e-mailed Dr. David Lean of the University of Ottawa, who supervised CBC’s tuna tests. The e-mail authors were worried they’d suffered mercury poisoning after eating too much canned tuna.

“I suggest they talk it over with their doctor,” Hayes said. “I don’t think the message is out there yet that this is a major environmental problem that really requires action at all levels.”

Under her doctor’s care, Hayes stopped eating canned tuna altogether. Eventually, the mercury levels in her blood dropped to normal and her symptoms have disappeared.

Since 2003, the U.S. Environmental Protection Agency and the National Academy of Sciences have recommended keeping mercury levels in the blood to less than five micrograms per litre over the long term. When first tested, Hayes’ blood levels were 8.8 micrograms per litre.

Health Canada’s guideline for mercury in blood were based on the World Health Organization’s standard from 1972, which indicate increased risk at levels between 20 to 100 micrograms per litre.

Entry for March 02, 2007

For the past couple of days I can feel a difference. The vibration is almost non existent and yesterday I decided to take three doses of 25 mg zinc. I actually reduced the zinc until this morning to three doses of 12.5 but I’ll switch back to the higher dose tomorrow. My nose didn’t feel as stuffy as it normally does and so I check my tongue for thrush. My thrush looks great and my chapped lips have improved as well. It’s all very subtle but this is working. In some ways, it’s working better than the actual candida diet and I stopped that a few days ago.

So is my candida related to a zinc deficiency? How many doctors suggested a zinc deficiency? Not one. Zinc can also effect the thyroid and the adrenals. A very interesting link…

Here’s what I found:


The functioning of the thyroid gland is one of the first activities interfered with by Candida, and it has been observed that 90% of Candida victims have low thyroid function. As with adrenal hormones, it appears that Candida receptor sites can bind thyroxine and render it physiologically unavailable.This may help explain the common finding of a normal blood level of thyroxine in a person who is clinically very obviously hypothyroid. Moreover, candidiasis is commonly associated with zinc deficiency, and since zinc is necessary for the conversion of thyroxine to its active form, tri-iodothyronine, such a deficiency could produce symptoms of hypothyroidism (which also could occur in the presence of normal blood levels of thyroxine).

Again, as with the adrenal glands, damage to the thyroid gland from Candida-induced free-radical activity and Candida-induced autoimmunity is a possibility.

Keep Yeast from Rising with Zinc

When it comes to fighting disease, the mineral zinc is often a heavyweight contender. It stimulates the production of T lymphocytes, the cells in your immune system that are responsible for cleaning up cells that have been invaded by infection. According to medical research, this makes zinc a prize-fighter against Candida albicans.

In fact, zinc supplements are likely beneficial even if your body’s zinc levels are normal, according to a study done in India. Researchers there worked with laboratory animals that were not deficient in zinc. They gave these animals high-dose zinc supplements and found that they were significantly more resistant to infection from Candida albicans than those not supplemented with zinc.

“Zinc is essential in preventing infection,” agrees Dr. Crook. “And though it’s best to get your vitamins and minerals through a healthy diet, supplementation is probably a good idea, given how many essential nutrients our food loses by the time it’s processed, packaged, shipped and bought.”

To fight candida, Tori Hudson, M.D., professor at the National College of Naturopathic Medicine in Portland, Oregon, suggests taking the Daily Value of zinc, which is 15 milligrams. And to get more zinc through your diet, try cooked oysters. They contain about 76 milligrams of zinc per half-dozen

Zinc is involved in many chemical reactions in the brain. It is essential in the development and continuous normal functioning of the central nervous system. There are many metalloenzymes and binding proteins in the body that require zinc for normal functioning.

In another immune stimulant capacity, zinc can offer some relief from chronic infections with Candida albicans, or yeast. Most women will experience a vaginal yeast infection at some time, and are particularly prone to them during the childbearing years. Some individuals appear to be more susceptible than others. One study showed yeast-fighting benefits for zinc even for those who were not deficient in the mineral to begin with. Other supplements that will complement zinc in combating yeast problems are vitamin A, vitamin C, and vitamin E.

Looking back, it always found it odd that for every doctor I mentioned a magnesium deficiency to, not one of them ever mentioned the other co-factors that could cause it. I know that copper has a relationship with magnesium so it’s my guess that I’ve had a low level of zinc or high level of copper for a very long time and this has upset the balance zinc/copper ratio and created a magnesium deficiency over fifteen years. So how many doctors suggested this possibility? Not one.


Bio-unavailable copper: Often copper status can be tricky to assess. Copper may be present, but unavailable for use in the body. This occurs any time adrenal gland activity is low.
