A recent study from researchers at the Mayo Clinic in conjunction with the Centers for Disease Control and Prevention (CDC) revealed that people following a gluten-free diet have significantly higher arsenic, cadmium, lead, and mercury levels in urine and blood than those not following a gluten-free diet. [1] 

Another similar study in 2006 revealed that vegans and vegetarians have an increased cadmium body burden in comparison to those following normal diets. [2] 

So why do gluten-free, vegetarian, and vegan diets increase the risk of heavy metal exposure? Increased consumption of two foods that are staples for all cultures around the world are the primary culprits: rice and green leafy vegetables.

Getting an early jump on a disease process like cancer makes treatment exponentially easier and outcomes generally better.

Under the current guidelines, that early jump on prostate cancer starts at age 55 for men at low to moderate risk and 40-45 for men at high risk. It takes years for cancer to grow to a detectable point after the tumor's initial induction from a normal cell to a cancerous one.

There's been a lot of research done to determine what those inducers are and how they work. Three of these inducers are simple to test for and completely modifiable with treatment and/or avoidance:

  • Bisphenol A
  • Arsenic
  • Catechol estrogens

Elements Testing – Why Sample Type Matters!

Posted by Ted Zava on Tuesday, 03 May

Urine, serum, plasma, whole blood, red blood cells, feces, hair, fingernails…the list goes on.

How do you decide what biological sample(s) to use for element analysis? Can results be compared to scientific literature or do they have clinical significance? Is it possible for values to be elevated or low in one sample type and normal in another? Do test results indicate recent intake, body burden, acute toxicity, chronic toxicity, deficiency, or homeostatic regulation?

These are just some of the questions facing a testing laboratory when they want to develop and validate essential and toxic element profiles that will provide clinically meaningful results.
