If food could be controversial, then tuna must be in the conversation. There is so much talk as to how much mercury is in the fish and how damaging it could be. Mercury, in excessive amounts, can be damaging to the nervous system, liver, kidneys and practically the whole body! Yet with the excessive toxicity it is commonly used in tooth fillings such as amalgam. Always refuse amalgam fillings as these are composed of mercury and are common sources of mercury poisoning.

But, what about the fish? Okay, well the most common fish to watch for mercury are the large fish such as tuna, shark, mackerel and swordfish. These fish are highest in the food chain, so they eat all the other little fish. Little fish have little quantities of mercury. The big fish eat a lot of little fish, and all that mercury builds up in the big fish, which is why we find high amounts of mercury in bigger fish.

Does this mean you should stop eating fish? NO! Instead fish is much healthier than most red meat and chicken in the market. Try eating smaller fish like salmon, tilapia, flouder, bluefish and snapper.

A recent study done by Purdue University found that when individuals ate tuna the amount of mercury absorbed decreased after consuming oat bran, wheat bran and black tea. In many Asian cultures that consume large amounts of fish, they also have a high intake of tea, coincidence? Likely not so.

Here are a few products that would help with inhibiting mercury absorption:

Solaray – Black Tea Extract

Choice Organic – Black Tea

Now Foods – Oat Bran

Folks worried about their heart health will be relieved to learn that a number of recent studies suggest that you already have a cheap yet very powerful weapon against heart attacks, strokes and other heart disease conditions. At a cost of less than $2 it sits, waiting, on your bathroom counter and is none other your humble toothbrush.

Researchers have found that people with Periodontal Disease are almost twice as likely to suffer from Coronary Artery Disease as those without Periodontal Disease. One study even found that the presence of common problems in the mouth, including gum disease (Gingivitis), cavities and missing teeth, were as good at predicting Heart Disease as cholesterol levels!

How can that be? Some studies point to the culprit in the, ‘bad gums = heart disease’ connection as an inflammatory process. They explain that plaque build-up at the gum-line, produces inflammation which sets-off a cascade of events producing inflammation in the arteries of the heart.

Oral bacteria may provoke inflammation, which may increase levels of white blood cells and C-Reactive Protein, or CRP, Will said. C-Reactive Protein is an inflammatory marker found in the blood that has been linked to Heart Disease.  A form of this protein called, ‘Highly Sensitive CRP (or hs-CRP) is considered a good predictor of recurrent heart attacks. The hs-CRP is also associated with lower survival rates, according to the American Heart Association.  Consumer Reports cites a recent study that found periodontal therapy actually reduced patients’ levels of CRP.

Yet most recent studies point to bacteria rather than CRP as the connection between Heart Disease and Gum Disease. Researchers at Howard University did a retrospective look at 11 studies that examined the connection between Periodontal Disease and Heart Disease.

Results point to a strong correlation between subjects’ levels of systemic bacteria, the presence of Periodontal Disease and the development of Heart Disease.  “They found that individuals with Periodontal Disease whose biomarkers showed increased bacterial exposure, were more likely to develop coronary heart disease or atherogenesis;” which is the formation of artery-blocking plaque, according to study results published by the American Academy of Periodontology.

Periodontitis has been linked in multiple studies not only to heart disease, but also Diabetes complications, pneumonia, stroke and even premature births.

The milder form of gum disease is gingivitis and, with proper treatment, it usually can be reversed with improved oral care and mouth rinses. The more aggressive form is periodontitis, according to the American Academy of Periodontology.  When the gums become red and inflamed due to poor oral hygiene or a disease in the body affecting soft tissue, “the spillover of bacteria gets into the bloodstream,” said Gayle Will, deputy health editor of Consumer Reports.

Another study by researchers at Columbia University’s Mailman School of Public Health in New York looked at people with no known Heart Disease, and the levels of bacteria in their mouth. They found people with higher blood levels of certain oral bacteria were more likely to have clogged carotid arteries in the neck, which can cause strokes.  Yet the lead author of that study, Dr. Moise Desvarieux, said the results could lead to the old “which-came-first, the-chicken-or-the-egg” question. It is difficult to know for certain whether one caused the other and further research is needed.

Still, he suggests, even if severe gum disease doesn’t cause Heart Disease, it could be just as important to know if Gum Disease is a precursor to heart disease. That’s because Heart Disease is difficult to diagnose before patients are symptomatic — and sometimes by then, significant damage is already done.

Why not begin to make changes to safe-guard your heart health today?  You can easily start by establishing a routine of flossing and brushingafter each meal, followed by a refreshing natural mouth rinse. This is especially important as a bedtime habit.  A lot can happen to your mouth in eight hours — especially when you’re sleeping and bacterium are gathering on your teeth.

So start your new routine today!

Best Health,
