Brussels Sprouts & Healthy Estrogen Metabolism

Posted by ZRT Laboratory on Friday, 21 July

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.

I wanted to share a few of the studies using saliva testing that were published in the literature in 2016.

Just a hint, if you want to search for articles on saliva testing, use pubmed.gov and search saliva estradiol (or progesterone, testosterone etc.).

Be aware that saliva hormone testing is so standard in the research world that rarely is it mentioned in the titles of the papers. Over 310 studies were published in 2016 using saliva testing – 61 studies for testosterone and 189 studies on cortisol, while poor progesterone was neglected with only 14 studies this last year.

It’s always good to know that the work that ZRT has been doing for almost 20 years in the field of saliva testing is still cutting edge and useful.

Not many people realize this, but estrogen plays a role in more bodily functions than just reproduction. In fact, estrogen has many important functions in the brain. 

Studies show that decreasing levels of estrogen can cause two of the most common perimenopause symptoms hot flashes and mood fluctuations. Curious how this happens? Read on to learn the details of this biochemistry.

Doing so could not only increase many womens’ chances of recovering from breast cancer – as the latest research indicates – but could also help them to avoid getting breast cancer in the first place.
