Cadmium’s Connection to Infertility and Reproduction

Cadmium is a dangerous heavy metal and a known carcinogen. Even though daily exposure is usually relatively low compared to toxins like arsenic, cadmium bioaccumulates with a half-life in the body of 25-30 years.

Essentially, the older you are, the more cadmium you have stored in your body. When cadmium exposure is high, it increases cellular oxidation products that deplete antioxidants like glutathione peroxidase and superoxide dismutase, rendering the body defenseless to further oxidative damage [1].

The most common sources of cadmium exposure are green leafy vegetables and grains, as cadmium is accumulated from contaminated water and soil. Thus, people consuming plant-based diets may be at a higher risk for cadmium exposure. Tobacco, a green leafy plant, concentrates cadmium, which is then highly absorbed through the lungs when smoked, resulting in blood cadmium levels 3 times higher than in non-smokers [2]. In comparison, only a small percentage of cadmium is absorbed in the gut from food. Other sources of cadmium include industrial activities such as smelting and refining, mining, and manufacturing of batteries and cadmium-containing pigments.

Influenced by our environment, we are constantly being exposed to elements, whether nutritional or toxic. They are a big contribution to the yin yang dualism of health and disease. 

With heavy metals, contamination is so extensive nowadays that it is no longer a question of whether exposure took place, but rather what the level of exposure was or continues to be.

Is Sweating a Good Bet for Heavy Metal Detox?

A couple years back, I wrote a blog about iodine deficiency in athletes resulting from excessive sweat loss.

Later, while studying the kinetics of the iodine loading test which involves taking a 50-mg dose of iodine and collecting urine for 24 hours, I investigated the excretion of iodine in sweat along with urine.

Surprisingly iodine levels in sweat tracked urine iodine excretion over a period of 3 days. The goal was to show that the loss of iodine through sweat can represent a significant portion of the 50-mg dose, something the creators of the Iodine Loading Test had not accounted for.

Keeping Your Child Safe From Toxic Baby Food

Posted by Dr. Alison McAllister on Friday, 10 November

Is there anything more endearing than the photographs of your baby eating his or her first foods? Their faces squish-up, they are covered from head to toe, their tongues protrude to catch every bite or more often to try to get the revolting taste out of their mouths.

Now, we parents are the ones squishing up our faces and showing huge grimaces of disgust at the latest report that our baby food is contaminated by metals – arsenic, lead, cadmium – none of it monitored or regulated by the FDA.

The non-profit Clean Label Project independently analyzed 500 baby formulas and prepared baby foods (formula, food, pouches, snacks, drinks, cereals) from 60 companies and found the following horrifying information.
