Will Soy Put Out The Fire?

Author: Dr. Stephen Chaney

 

soy and hot flashesThere has been a lot of controversy in recent years about soy and hot flashes. The question is whether soy isoflavones reduce the hot flashes associated with menopause.

And this is an important question! Because of concerns about increase heart attack risk with hormone replacement therapy (HRT) many women have been looking for natural alternatives to HRT for reducing hot flashes and other symptoms of menopause. They’ve been asking whether soy isoflavones are effective, and the answers that they’ve been getting have been confusing.

For example, you can still find many experts and health professionals who will tell you that soy isoflavones have no proven effect on menopause symptoms.

That is somewhat surprising since two recent meta-analyses (Howes et al, Maturitas, 55: 203-211, 2006; Williamson-Hughes, Menopause, 55: 203-211, 2006) and a 2010 expert panel of The North American Menopause Society have all concluded that soy isoflavones alleviate hot flashes.

Will Soy Put Out The Fire?

However, clear guidance in this area was sorely needed, so Taku et al (Menopause, DOI: soy10.1097/gme.0b013e3182410159, 2012) performed an even larger meta-analysis that included 19 published clinical trials – some of which had been published after the previous two meta-analyses were performed.

I’ve talked about meta-analyses before, so you probably already know that they are very powerful because they combine the results of many individual clinical trials into a single data analysis.

But you also may remember me telling you that meta-analyses can be misleading if they introduce bias because of the kinds of clinical studies that they exclude from their analysis.

So I examined the design of this meta-analysis very carefully. It excluded clinical trials that:

  • were not double blind, placebo controlled and designed in such a manner that the placebo was indistinguishable from the soy isoflavone preparation.
  • contained other substances in addition to the soy isoflavones (The presence of other substances in the preparation might have influenced the response).

There were several other well justified reasons for excluding some studies from the meta-analysis, but they were technical in nature. In my opinion this was a very well designed study.

And the results were clear cut. An average of 54 mg of soy isoflavones (some studies used a little less, some a little more) was sufficient to reduce:

  • the frequency of hot flashes by 21% – and –
  • the severity of hot flashes by 26%

Soy and Hot Flashes: What This Study Mean For You?

The results of this study were highly statistically significant. So if you are suffering from hot flashes and are wondering whether soy isoflavones will put out the fire, the answer appears to be YES.

That’s the good news.

The bad news is that 21-26% is not a huge effect.

And, if you look at the individual clinical studies it is apparent that the response is highly variable. Some women experience major relief from hot flashes and other menopause symptoms, while other women experience little or no relief.

The reason for this variability is not known, but it is likely that the effectiveness of soy isoflavones on reducing hot flashes is modified by other components of the diet and by lifestyle factors such as obesity, exercise and stress.

Soy and hot flashes; the bottom line.

My take on this is that soy isoflavones should not be thought of as a “magic bullet” that will make hot flashes go away by themselves, but rather as a proven part of a holistic approach that encompasses a healthy diet, exercise, weight control and stress reduction

The Bottom Line

  • A recent meta-analysis of 19 published clinical studies showed that soy isoflavones reduced the frequency of hot flashes by 21% and the severity of hot flashes by 26%.
  • The results were highly statistically significant, but 21-26% reduction in symptoms is not a huge effect.
  • When they looked at the individual clinical studies it was apparent that the response is highly variable. Some women experienced major relief from hot flashes and other menopause symptoms, while other women experienced little or no relief.
  • My take on this is that soy isoflavones should not be thought of as a “magic bullet” that will make hot flashes go away by themselves, but rather as a proven part of a holistic approach that encompasses a healthy diet, exercise, weight control and stress reduction

Shermer’s Neck Is An Ultra-Cyclist’s Nightmare

shermer's neck pain ultracyclistShermer’s Neck is a condition where the muscles of the back of your neck become so tight that they lose the ability to hold your head up. It is a condition most frequently associated with ultracycling.

Do you love to cycle?  Perhaps you’re an ultracyclist and ride for many hours every week.  If you are, you may already know about Shermer’s Neck.

As you are well-aware, an ultracyclist leans forwardThis is called the “aerodynamic position.” When you do that, you are slicing through the wind, and you aren’t losing speed when the wind hits your chest. However, you need to hold your head up to see where you are going and maintain that position for several hours. That is what causes Shermer’s Neck.

Shermer’s Neck And The Non-Athlete

shermer's neck pain painterYou don’t have to be an ultracyclist to suffer from Shermer’s Neck. Do you do anything that has you look up for hours, such as being a house painter? Even something as simple as having your computer screen too high can force you to have your head tilted up for long periods of time while working.

If so, Shermer’s Neck can still affect you, and seriously impact your life. Fortunately, non-athletes don’t usually have as severe a problem as the ultracyclists.

Why Does Looking Up Cause Shermer’s Neck?

shermer's neck painYour posterior neck muscles primarily originate at the middle of your back, along your spine. They go up your back and neck, and insert into either your cervical spine, or the bottom of your skull. When these muscles contract, they pull your head back.  When the muscles of the posterior neck contract, if you are standing, you’ll be looking at the ceiling. If you’re a cyclist, your posterior neck muscles contract in order for you to look forward.
