Does eating soy foods help with hot flashes?

Discuss
Republish

All right, back to foods. Does soy consumption help ameliorate symptoms of menopause? Now, as with nearly everything in the field of human nutrition, the evidence is mixed. So the question is always what does the balance of the evidence show? To bean, or not to bean?

Here’s what the science shows. There have been a dozen studies on soy consumption and hot flashes, and one showed an increase in hot flashes (the one at the bottom). Three didn’t show soy did much of anything, but the remaining eight studies showed a significant reduction in hot flashes.

You can imagine what the headlines were like after the publication of that last study. “Soy doesn’t work!” But you have to take the totality of evidence, and overall, soy really does seem to help.

To see any graphs, charts, graphics, images, and quotes to which Dr. Greger may be referring, watch the above video. This is just an approximation of the audio contributed by veganmontreal.

    1. Soy causes kidney stones for me… off limits. I am whole foods plant based but hitting 65 this year. Has anyone had any good results with something besides SOY for improving estrogen? I have lactose issues, soy, issues, nut issues, kidney stone issues (Which blocks some of my favorite foods like spinach, chard, strawberries etc) I would appreciate some response or ideas. Menopause was a breeze with a clean diet… and life has been extraordinary as we have continued to keep a clean diet with very very limited meat exposure when eating out at holiday parties… whole foods plant based, no dairy, no meats, no processed foods. I am close to my wedding weight at age 65 and feeling great but the lack of estrogen has created a slowdown sexually with pain. I have found nothing in your videos addressing this. I did just view the video on men and heart attacks and sex… and I can confirm without a doubt that a clean whole foods plant based diet made a HUGE difference for my husband.

      1. Congratulations on maintaining your weight and keeping to your healthy diet. You asked about other foods that might help with estrogen balance besides soy. I believe these other articles will help:
        Evaluation of the Estrogenic Effects of Legume Extracts Containing Phytoestrogens
        http://pubs.acs.org/doi/full/10.1021/jf021114s This study found some common and not so common foods you could try:
        Kudzu root, red clover blossom and sprout, mung bean sprout, and alfalfa sprout all of which showed estrogen effects.

        https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3074428/
        This study defines phytoestrogens are naturally-occurring plant compounds that are structurally and/or functionally similar to mammalian estrogens and their active metabolites including One major class is the lignans, which are components of plant cell walls and found in many fiber-rich foods such as berries, seeds (particularly flaxseeds), grains, nuts and fruits. Berries, wine grains and nuts are also cited as having good potential to act as estrogens in the body. Think legumes also!

  1. Hello, Michael!

    Question: A coworker takes an estrogen patch and in her efforts to make the switch to a vegan diet, is concerned that soy will cause some problems since she cannot control the amount of estrogen she receives from this patch. What advice would you give someone in this situation in regards to Soy consumption?

    Regards,
    Scott

      Hi Scott,

       

      If there is one thing that holds true, nutrients in its
      original source are healthier than other types of (artificial) supplementation.  Your coworker may find her menopausal symptoms
      (assuming this is why she has the patch) have lessened the more whole foods she
      is consuming (and the bad stuff she’s ditching) in general.  With the consult of her doctor, she may want
      to ditch her artificial supplementing for a whole-foods, plant-based diet to
      help her menopause. 

       

      Regardless, every day more and more evidence comes out about
      the benefits of soy and not just with menopause!  Here you can see how the forms of soy compare
      to each other health wise.  http://nutritionfacts.org/video/tofu-vs-tempeh-2/

      Many of the studies support a daily consumption of soy (1-2
      servings), which is how the Asians typically eat.  Here are two great but short reads on current
      research of soy and Breast Cancer.  In
      addition it explains why previous studies using lab animals misguided us on how
      soy is processed in the human body.

      Here is a great video on the subject also!

      Here is also a video on the benefits of soy beans in
      general.

      Just on a side note, here is a video providing evidence of
      the negative health consequences of taking supplements.

      I wish your coworker great luck with her healthier life
      changes.

    2. You have to watch soy if you are kidney stone prone. Soy is one of the big causes. There is a higher rate of kidney stones in younger women suddenly because of the addition of not only soy to the diet and ALL the processed foods which now contain it, but all the green drinks they consume with chard, spinach and kale. Soy is not necessarily a healthy alternative. Just speaking from experience and a whole foods plant based diet with Forks over Knives for the past 6 years.

  2. A larger question would be why humans experience menopause much earlier than other primates. For instance, one study I’ve found says chimps don’t experience it until 90% life span.

    1. It’s because our offspring take so long to mature. We need to live longer (and have more infertile years) in order to ensure their survival and the survival of our grandchildren–our gene pool :)
      There are studies showing that having the grandmother around increases the survival rates for the grandchildren–especially in less industrialized cultures.

  3. My wife and I eat the same vegan meals. But where my LDL cholesterol is 50, hers is 104. The HDL numbers are closer with mine at 50 and hers at 66.She is 59 years old and started menopause 2-4 years ago. Could the menopause have any affect on raising her LDL cholesterol? And If not, what else could raise a vegan woman’s LDL cholesterol.

    1. Since soy is a xenoestrogen (plant estrogen) and your wife’s bodily make up is estrogen, perhaps that along with menopause is the difference between her cholesterol levels are you own. This is a guesstimate. I’m no expert.

    2. Have her thyroid checked (T3, T4, TSH and antibodies). Cholesterol is used to make thyroid hormone and sometimes there is correlation between low thyroid function and higher cholesterol.

  4. Is there a difference between using soy beans in their whole form (I/E – edamame, or mature soy beans to make soy milk) and soy protein isolate, in their effects of hormones? Thank you so much for all of the great information!

  5. Soy does affect hormones in my experience, but depending on one’s needs it can be for the good or bad. I need my estrogen and progesterone balanced or I get depression. Soy puts off the balance so I must stay away from it and balance my hormones with an HRT patch.

    1. Not much hope here… I just basically posted the same question and it is 2017. You have no answers here. Hubby and I are whole foods plant based, but before he was, I was still good with estrogen…then in the change over in his body, he is ready and my levels have dropped off the charts. I still have the appetite for it but vaginal dryness is not fun. Would like to know what Dr. recommends for women…and NOT SOY.

  6. ”Eating soy foods appears to help with hot flashes and other symptoms of menopause.” If you have a thyroid problem you’re not supposed to eat soy… What would you recommend a menopausal woman with a thyroid problem to take? Hope you’re able to answer. Can’t get a good enough answer from my doctor.

  7. 56 yr old post menopausal woman plagued by hot flashes for 3 years –I need Dr G’s help! Rapidly cycling hot flashes at night wake me up, not drenched but actually wet, 12-20 times nightly. I have been doing whole food plant based diet for years, am healthy, roughly correct weight, exercise daily…. I keep thinking surely these pesky hot flashes will go away but so far they have changed (used to be more heat, less often, now more surges, but to lesser peak heat) but are persistant. I am worried that chronic sleep deprivation is really going to hurt me. I have family history for breast cancer so am wary of estrogen. Suggestions?

    1. Hi Michelle: I’m sorry to hear you’re having trouble with mood swings. Sounds like you’re off to a great start by following a WFPB diet. Have you considered other lifestyle changes? Regular exercise, cutting back on caffeine, avoiding alcohol, and stopping smoking (if you’re a smoker) may ease symptoms. Getting enough sleep and using relaxation/stress management techniques (mindfulness/meditation/yoga) may help as well. You can find more information on mood here.
