People should know about their clotting risk before supplementing though. https://www.stoptheclot.org/learn_more/womens_health_faq/ 

 

I always assumed the heart risk would make hormone therapy contraindicated for me, but it now appears that the overall risk/benefit very well may make it healthier for me to be on it than not. Estrogen therapy significantly reduces the risk of heart disease, Alzheimer’s, and hip fractures (due to reducing osteoporosis). I still feel uneasy about stroke risk, but the overall data is compelling to me. How does one find out their clotting risk?

I think you have to know your family history. Age makes a difference. Also an autoimmune condition can make you more susceptible, so talking to a rheumatologist or immunologist is a good idea if you have an autoimmune disease. Lupus is the one that is most famous for this (antiphospholipid antibody syndrome), but you can have the clotting associated with it without having lupus.

There are situational reasons for clotting that aren't hereditary, such as having a central line, PICC line, or certain other types of access lines placed, immobilization, etc. From the thrombosis site...

Risk factors that contribute to thrombosis include:

  • A hospital stay
  • Surgery
  • Major trauma, such as a car accident, fall, or head injury
  • Infection
  • Inflammatory or autoimmune disease
  • Active cancer/chemotherapy
  • Estrogen-containing birth control pills and hormone replacement therapies
  • Pregnancy
  • Obesity
  • Leg paralysis
  • History of heart attack or stroke
  • Prior blood clot(s)
  • Family history of blood clots
  • Genetic or acquired clotting disorders
  • Immobility (limited movement), including:
    • Being on bedrest
    • Being sedentary, meaning that you sit most of the day and are not physically active
    • Traveling for long periods of time (4+ hours on a plane, car, or train)

We have a ton of hereditary risk in our family. Only one person has a firm diagnosis--some have been tested but not others, and the condition that one person has is not directly hereditary. It's frustrating. 

I mention it just because clots are an overlooked and underappreciated area of medicine--they happen often, but medicine hasn't always done a good job of explaining and managing them.

ETA: Here is the thrombosis site. I forgot which thread I was in. PE came up on a Covid booster thread, so I posted some stuff there.https://thrombosis.org/patients/what-is-thrombosis/

It makes sense that soy diets alleviate the hot flashes due to the high amount of phyto-estrogen in soy.  If you're avoiding HRT, you might want to avoid soy as well.

Soy is beneficial without having the negative side effects of HRT. Here's an explanation of why soy is a safe alternative:

https://nutritionfacts.org/2019/11/21/how-phytoestrogens-can-have-anti-estrogenic-effects/

When the Women’s Health Initiative study found that menopausal women taking hormone replacement therapy suffered “higher rates of breast cancer, cardiovascular disease, and overall harm,” a call was made for safer alternatives. Yes, the Women’s Health Initiative found that estrogen does have positive effects, such as reducing menopausal symptoms, improving bone health, and reducing hip fracture risk, but negative effects were also found, such as increasing the blood clots in the heart, brain, and lungs, as well as breast cancer.

Ideally, to get the best of both worlds, we’d need what’s called a selective estrogen receptor modulator—something with pro-estrogenic effects in some tissues like bone but at the same time anti-estrogenic effects in other tissues like the breast. Drug companies are trying to make these, but phytoestrogens, which are natural compounds in plants, appear to function as natural selective estrogen receptor modulators. An example is genistein, which is found in soybeans, which happen to be structurally similar to estrogen. How could something that looks like estrogen act as an anti-estrogen?

The original theory for how soy phytoestrogens control breast cancer growth is that they compete with our own estrogens for binding to the estrogen receptor. As more and more soy compounds are dripped onto breast cancer cells in a petri dish, less and less actual estrogen is able to bind to them. So, the estrogen-blocking ability of phytoestrogens can help explain their anti-estrogenic effects. How do we then explain their pro-estrogenic effects on other tissues like bone? How can soy have it both ways?

The mystery was solved when it was discovered there are two different types of estrogen receptors in the body and the way in which a target cell responds depends on which type of estrogen receptor they have. The existence of this newly discovered estrogen receptor, named“estrogen receptor beta…to distinguish it from the ‘classical’ estrogen receptor alpha,” may be the “key to understanding the health-protective potential of soy” phytoestrogens. And, unlike our body’s own estrogen, soy phytoestrogens preferentially bind to the beta receptors.

For instance, within eight hours or so of eating about a cup of cooked whole soybeans, genistein levels in the blood reach about 20 to 50 nanomoles. That’s how much is circulating throughout our body, bathing our cells. About half is bound up to proteins in the blood, so the effective concentration is about half the 20 to 50 nanomoles. What does that mean for estrogen receptor activation?

In my video Who Shouldn’t Eat Soy?, I feature a graph explaining the mysterious health benefits of soy foods. Around the effective levels we would get from eating a cup of soybeans, there is very little alpha activation, but lots of beta activation. What do we find when we look at where each of these receptors are located in the human body? The way estrogen pills increase the risk of fatal blood clots is by causing the liver to dump out extra clotting factors. But guess what? The human liver contains only alpha estrogen receptors, not beta receptors. So, perhaps eating 30 cups or so of soybeans a day could be a problem, but, at the kinds of concentrations we would get with just normal soy consumption, it’s no wonder this is a problem with drug estrogens but not soy phytoestrogens.

The effects on the uterus also appear to be mediated solely by alpha receptors, which is presumably why no negative impact has been seen with soy. So, while estrogen-containing drugs may increase the risk of endometrial cancer up to ten-fold, phytoestrogen-containing foods are associated with significantly less endometrial cancer. In fact, protective effects are found for these types of gynecological cancers in general: Women who ate the most soy had 30 percent less endometrial cancer and appeared to cut their ovarian cancer risk nearly in half. 

Soy phytoestrogens don’t appear to have any effect on the lining of the uterus and can still dramatically improve some of the 11 most common menopausal symptoms (as compiled by the Kupperman Index).

In terms of bone health, human bone cells carry beta estrogen receptors, so we might expect soy phytoestrogens to be protective. And, indeed, they do seem to “significantly increase bone mineral density,” which is consistent with population data suggesting that “[h]igh consumption of soy products is associated with increased bone mass…” But can soy phytoestrogens prevent bone loss over time?

In a two-year study, soymilk was compared to a transdermal progesterone cream. The control group lost significant bone mineral density in their spine over the two years, but the progesterone group lost significantly less than that. The group drinking two glasses of soymilk a day, however, actually ended up even better than when they started.

In what is probably the most robust study to date, researchers compared the soy phytoestrogen genistein to a more traditional hormone replacement therapy (HRT) regimen. Over one year, in the spine and hip bones, the placebo group lost bone density, while it was gained in both the soy phytoestrogen and HRT estrogen groups. The “study clearly shows that genistein prevents bone loss…and enhances new bone formation…in turn producing a net gain of bone mass.”

The main reason we care about bone mass is that we want to prevent fractures. Is soy food consumption associated with lower fracture risk? Yes. In fact, a significantly lower risk of bone fracture is associated with just a single serving of soy a day, the equivalent of 5 to 7 grams of soy protein or 20 to 30 milligrams of phytoestrogens, which is about a cup of soymilk or, even better, a serving of a whole soy food like tempeh, edamame, or the beans themselves. We don’t have fracture data on soy supplements, though. “If we seek to derive the types of health benefits we presume Asian populations get from eating whole and traditional soy foods,” maybe we should look to eating those rather than taking unproven protein powders or pills.

Is there anyone who should avoid soy? Yes, if you have a soy allergy. That isn’t very common, though. A national survey found that only about 1 in 2,000 people report a soy allergy, which is 40 times less than the most common allergen, dairy milk, and about 10 times less than all the other common allergens, such as fish, eggs, shellfish, nuts, wheat, or peanuts.

That was super informative--I will try to remember to take this to my women's health nurse practitioner. She's not anti-soy, but my estrogen has been so sky high that she felt like she couldn't recommend it to me. Now to find a way I would actually eat it, lol...

I'm glad you found it helpful!

When it comes to eating soy, here's what works for me (I eat 2-3 servings of soy per day):

1. Soy milk - I have it on my oats every morning and use it in recipes that call for milk/plant milk.

2. Edamame - I buy frozen edamame and keep a bowl of it (thawed) in the fridge. That makes it easy to throw into salads, stir fries, soups, sandwiches, or just snack on it.

3. Tofu - There are so many great tofu recipes. I also keep baked tofu in the fridge for sandwiches, salads, etc.

4. Soybeans - Soybeans can be used in any recipes that call for beans. They have a mild taste, similar to cannellini beans. Soybean hummus is great. I buy them dried, but canned soybeans are also available.

Tempeh is another option - that's the one soy food I am not that crazy about, but lots of people love it.

Thanks...not a fan of any of the first three, but I would be willing to try #2 again because I don't remember it well. I haven't tried #4, but I like cannellini beans (and most other beans). Had tempeh once and liked it, but I have no experience cooking it myself. I think a lot of veggie burgers have soy, but they often also have spices or flavorings that I can't have. I will be looking though!
