Brussels Sprouts & Healthy Estrogen Metabolism

Posted by ZRT Laboratory on Friday, 21 July

Brussel Sprouts and Good EstrogenYou might ask what Brussels sprouts and estrogens are doing in the same sentence, but I am here to tell you that there is a connection.

Brussels sprouts are the cruciferous connection to healthy hormone metabolism. These age-old options –including cabbage, broccoli, bok choy and cauliflower – have gained new acclaim today as dietary super foods. These plants, cultivated for centuries and originally used as medicines, can nourish us towards superior health and hormone balance.

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

Breast Cancer: Fear & Preventative Double Mastectomies An Unnecessary Mix

Posted by Dr. Allison Smith on Thursday, 29 May

b2ap3_thumbnail_86492411_20140529-171654_1.jpgThe recent news about a study regarding women who get mastectomies to prevent breast cancer is stunning.  

This study finds most women who get double mastectomies don’t need it. They react out of fear. And this has many doctors puzzled.

Breast Cancer & Biochemistry

Can we prevent breast cancer occurrence through primary care means? The short answer is yes, we can.

We can identify breast cancer risks. We can do functional lab testing to assess nutritional and endocrine balance and test for products of hormone metabolism. We can treat the imbalances we find and monitor progress through lab work and imaging. We can achieve this by understanding some pretty basic biology and biochemistry, and applying it to our patients to help them overturn early cancerous processes in the body and improve overall health.

Why Should We Care About Estrogen Metabolites?

Posted by Margaret Groves on Wednesday, 05 February

trashcan_urine.metabolites.jpgPractical Takeaway: The liver's ability to properly metabolize estrogens has been found to affect the risk of breast cancer. Depending on which of the metabolic pathways predominate, too much of certain harmful estrogen metabolites (e.g., 4-hydroxy estrogens) can build up - and these have been found to correlate with breast and other hormone-dependent cancers.
