IAMOT 2016 Comprehensive Review of Dental Mercury

Title: A Comprehensive Review of the Toxic Effects of Mercury in Dental Amalgam Fillings on the Environment and Human Health
The International Academy of Oral Medicine and Toxicology – 2016 Update  

Dentists around the world routinely use dental amalgam as a filling material in decayed teeth. Often referred to as “silver fillings,” all dental amalgams actually consist of 45-55% mercury. Mercury is a known neurotoxin that can cause harm to humans, especially children, pregnant women, and fetuses. The use of dental amalgam results in substantial quantities of toxic mercury released annually into the environment. Once in the environment, mercury pollution damages animals, plants, and the entire ecosystem.

Lifestyle Advice from the World Health Organization to Avoid Cancer and Chronic Disease

In order to avoid cancer and chronic disease, the World Health Organization recommends that BMI be maintained between 21 and 23 and that moderate physical activity, equivalent to a brisk walk, is completed for at least 30 minutes every day, with the aim of 60 minutes of moderate or for 30 minutes or more of vigorous physical activity every day. In addition to these guidelines, they suggest limiting red meat, alcohol, salt as well as eating at least five portions of a variety of non-starchy vegetables and fruits every day, along with unprocessed grains and legumes with every meal.

American Cancer Society Guidelines on Nutrition and Physical Activity for Cancer Prevention

Genetics can influence the risk of cancer, but cancer risk can be affected by lifestyle choices, which are not genetically inherited. For people who do not smoke, the most important lifestyle cancer risks include weight control, diet and levels of physical activity. It is recommended to be as lean as possible throughout life without being underweight and to engage in regular physical activity, while limiting sedentary behaviour. A healthy diet low in high-calories foods and beverages with an emphasis on plant foods (at least 2.5 cups of vegetables and fruits each day), rich in whole grain products and limited in alcoholic beverages are dietary strategies that can prevent cancer.
