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.

Toxic Baby Food: A Look Beyond the Labels

A recent news story [1] reports that the Clean Label Project, a non-profit organization focused on health and transparency in consumer product labeling, tested 530 baby food products for toxic elements and chemicals. The results were not good.

Sixty-five percent of products tested "positive" for arsenic, 36% for lead, 58% for cadmium, and the tests even showed high levels of BPA in “BPA Free” products. These toxins are harmful to infants (and adults), and can lead to developmental delays and permanent damage to the brain, kidneys, liver, bladder, and many other organs in the body. Arsenic and cadmium are known carcinogens while lead, a damaging neurotoxin, accumulates in bone and is released back into the bloodstream when bones develop (a continuous source of exposure) [2].

All toxin exposure should be limited, especially during infancy and childhood when the brain and other organ development is at its most sensitive.

Does Following a Gluten-Free, Vegetarian or Vegan Diet Result in Increased Heavy Metals Intake?

Posted by Ted Zava on Friday, 17 March

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.

3 Keys to Preventing Prostate Cancer

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
