This episode in controversial in nature and does not necessarily express the opinions of Chef AJ and the producers of this video.
Dr. Rogers provided all of the research studies that he cited but I am only able to include a few as the TH-cam a limit of 5,000 characters.
You tube channel “Dr Anthony Jay.” Phd biochemist, expert on blood lipids, like estrogen, videos about the estrogenic effects of soy.
“Estrogeneration” book by Anthony Jay Phd 2017 cites numerous studies about estrogenic effects of soy, and concerns for possible carcinogenic effects.
Sheehan (2002) “Goitrogenic and estrogenic activity of soy isoflavones” environmental health perspectives, vol 110, June. → A review paper. Says soy has a frenk estrogenic effect in women. Suggests a link between soy consumption and goiter. In rats, genistein is a/w 80% inhibition of enzyme TPO (Thyroid PerOxidase). Soy (genistein) a/w causing uterine adenocarcinoma in adult mice. In one study of women reviewed, soy caused a lengthening of the menstrual cycle (suggests an estrogenic effect). Says human infant soy intake a/w doubling the prevalence of autoimmune disease. Soy a/w problems with TPO in humans, porcine & bovine suggesting it’s a general problem across mammal species.
Kenan (2022) “Developmental exposure to phytoestrogens found in soy: new findings and clinical implications” biochem pharmacol, Jan; 195: 114848. “This indicates that in vivo genistein can have significant biological activity when present in concentrations similar to that of estradiol. In infants consuming soy formulas, plasma isoflavone levels are 13,000-22,000 times HIGHER than plasma estradiol levels, a scenario where genistein is likely to activate estrogen receptor mediated responses.” Recommends warning labels be places on infant soy formula products.
Adgent, Margaret (2018)“Longitudinal study of estrogen responsive tissues and hormone concentrations in [human] infants fed soy formula” j clin endocrinol metab, May 1; 103(5):1899-1909. Those fed soy formula with increased vaginal development, uterine volume and breast development = suggestive of estrogenic effects. Important paper showing DIRECT estrogenic effects in humans.
Allred (2001) “Soy diets containing varying amounts of genistein stimulate growth of estrogen dependent (MCF-7) tumors” cancer res, Jul 1; 61 (13. Soy with increased growth of HUMAN breast cancer cells (MCF-7) in vivo.
Allred (2001) “Dietary genistin stimulates growth of estrogen dependent breast cancer tumors similar to that observed with genistein” carcinogenesis, Oct; 22 (10): 1667. Glycoside genistin, like the aglycone genistein, can stimulate estrogen dependent breast cancer cell growth in vivo. Removal of genistin or genistein from the diet caused tumors to regress.
Zeng (2020) “Effect of soy intervention on insulin like growth factor levels: meta-analysis” phytother res, Jul; 34 (7): 1570-1577. Study showed that soy increased ILGF in humans. (This is of concern, b/c elevated ILGF has been associated with increased risk of diabetes and cancer). I don’t know how much it increased ILGF relative to other foods
Vemuri (2016) “Glycone rich soy isoflavone extracts promote estrogen receptor positive breast cancer cell growth” nutr cancer, May-Jun; 68 (4): 622-33. Says “several recent reports challenged the health benefits of soy isoflavones and associated them with breast cancer promotion.” Soy isoflavones were studied. Conclusion was “our results suggest that the glyconic daidzin rich soy isoflavone extracts may exert estrogenic effects and promote ER+ breast cancer growth.”
Duffy (2007) “Implications of phytoestrogen intake for breast cancer” Sep-Oct; 57 (5):260-277. Says “There is in vivo animal data suggesting the phytoestrogen genistein may interfere with the inhibitive effects of tamoxifen on breast cancer cell growth.”
Velentzis (2008) “Do phytoestrogens reduce the risk of breast cancer and breast cancer recurrence?” eur j cancer, Sep; 44 (13): 1799-806. Says “Short term intervention studies suggest a possible stimulatory effect on breast tissue raising concerns of possible adverse effects in breast cancer patients.”
Omg this person makes me happy. Not only is he a genius, but he’s hilarious!!! Great way to start my day listening to him.
So happy dr. Rogers is one of your regulars now. He's my best find of 2022, thanks to you Chef AJ.
Outstanding presentation - this is maybe my favorite presentation yet!
This Dr. Supports his thoughts with every scientific papers. Thank you for telling the truth
I LOVE his long and thorough presentation!!!
My favorite speaker Dr. Rogers! Thank you Chef AJ!
Thank you for bringing Dr, Peter back, Chef AJ! Looking forward for more of this Doc! 🌱👍🙏♥️
I am a very salt sensitive person. What he says about salt helps me plan meals better.
Could you consider a talk on Raw vs. Cooked plant foods to fight active solid tumor cancers? 🙏
I appreciate him. Original.
I love DR Peter
There are probably no other Doctor that personally reads and takes in so much facts as Dr Rogers. Impressing!!! However it would be very intersting to hear other WFPB Doctors opinion on Dr Rogers statements regarding estrogen/soy/flax. Especially intersting would be comments from Dr McDougall and Dr Greger I think. Maybe possible for chef AJ to arrange interviews with them after they listen to Dr Rogers AND after they have studied the books and papers that Dr Rogers refers to??
Waiting for Mic the Vegan's response. Even though, I'll still go with Dr. Roger's research and knowledge.
Yes please! This requires further investigation.
Excellent video. Thank you for providing a different perspective. It’s worth doing further research!
Love the 10 Commandments of nutrition!
To soy, or not to soy? To Flax, or not to Flax? These are the questions. Thank you Dr. Rogers!
As always goes above and beyond and that’s what we all need to understand things from the source to the end - appreciates his complete and thorough lecture. Many thanks!
Thank you for this program ,great job,this is awesome
Chef Aj first time I’m confused after a podcast Just saw Christie Funks podcasts Dr Barnard and Dr Furhman on this very channel and they support soy consumption including Dr Sherzai So please please put our minds to rest Just saw a video by Anne Esslesten on soy dessert so I’m at crossroads what to consume Please put our doubts at rest Mucg gratitude n thanks
Same, really up'd my soy consumption since my breast cancer happened amd then the whole concept is squelched.
@@bonniedavis7498 my best to you I guess moderation is key and better we stick to vegggies fruits and add soy n flax once a week maybe It’s just too confusing Dr lee says add olive oil Dr Fuhrman says No One says eat soy daily and she’s a number one breast surgeon and here there is a doctor putting soy consumption down Can’t tell you how confusing this is all .... leads to a food paranoia I wish to go back to the carefree days where we ate what we wanted Then the scare of organic n non organic At times I feel like just doing my own thing
Same. Other docs are saying phytoestrogens from plants are beneficial for us- both as supporting heart health and binding to estrogen receptors and blocking other environmental estrogens which are dangerous. I don’t know though- I’m not a scientist. I am however interested in preventing breast cancer. I thought that overly low estrogen wasn’t good. I guess I am looking for a fuller understanding of the role of estrogen throughout the lifespan for both men and women.
great talk Peter. l try not to use detergents to wash clothes. and lower chemicals l use on my body. l had to rethink the flaxseed the argument. l was using it because other doctors recommend it. thanks Peter for telling us the truth
Fortunately my body has rejected all soy. I wanted the benefits that other plantbased doctors boasted, but the digestive issues weren't worth it. Alfalfa sprouts have phytoestrogens and no one talks about it. I have been sprouting those to get the benefits without ingesting soy.
Dr Rogers has shared many recent studies showing whether or not soy phyto-estrogens effects breast cancer. I would ask were these studies done on groups who consume meat and dairy? If so a positive cancer result could be explained due to meat and dairy. These studies would need a vegan control group. The low cancer results in Asian rice groups who eat soy would be relavant. Also blue zone populations who do not eat soy, but are cancer free would suggest that Soy is not protective. Rice based Asian groups may have low cancer rates because of not consuming meat and dairy. I have seen that conclusion in other vegan lectures.
we can't compare cancer rates in blue zones. We do not have stats. Please search "Blue zones" in the National library of medicine. Okinawans (soy eating) - live 98-102. Ikaria (not soy-eating) live 8-9 years longer than Americans.
There is lots of population studies of and data from Okinawan, Seventh day Adventist (blue zones) starch consuming populations, and controlled studies comparing western diets to various vegetarian diets to strict low fat vegans that show low to zero prostrate and breast cancer in. The data is used by all the doctors whose lecture conclusions l trust to show that soy does not cause cancer and that it possibly does not prevent as well. It's fair to expect modern research to clarify when researchers are using western diet groups.
Also please see Dr McDougalls studies and conclusions on this topic from ancient starch based cultures.
I believe he might be right about immunosuppressive effects of flaxseeds based on improved/reversal of autoimmune conditions when immune system is overactive. That was beneficial in Dr. Goldner’s case having lupus reversal. Amazing info! I’ll give up soy if he is right. I believe he is. 🙏♥️
Yes! He brings up good points. Dr. Funk recommends flaxseeds and soy- but now, I’m wondering...
Love this guy
I stopped consuming soy after reading the book Estrogeneration by Dr. Anthony Jay.
Never looked back!!
Excellent information thanks!
I feel like I need further information on the body of research on estrogen. Also , the studies cited are mostly quite old- I have heard doctors say that the prohibition on soy is dated… Other respected doctors are currently claiming phytoestrogens are protective. Would like a deeper understanding of the nature of the studies and the kind of soy studied. (Lots of contaminated and gmo soy here.) I’d also like to know about the quantity of soy used in the studies. Here I am eating soy and flax because I have been told they protect against breast cancer. Dr. Rogers also made a claim about sulfur producing foods contributing to favorable conditions for cancer- that includes allium family and crucifers, both of which are said to protect against cancer. This is a great lecture though. I always learn a lot from Dr. Rogers even if I am left with questions. It’s hard to pull out single causative factors in the diet without controlling the entire diet. We mere mortal s tend to rely on experts to interpret these studies but there are many different kinds of research being referenced- epidemiological, in vitro, animal, and nutrition research of which there are many designs- some better than others. I do listen to Dr. Greger and sometimes he goes into the different kind of research being looked at.
I know a woman who had a total hysterectomy and is on a plant-based diet. She does not take any estrogen, eats soy products, and does not have any hot flushes.
I’m not the expert and my evidence mostly anecdotal. But Japanese women before Western Diet did not have a word in their language for hot flashes. Also low fat consumption really helps.
14:40 Finally someone put into words what I’ve been seeing for so long: All those butchers look so insanely unhealthy and like the stuff they’re selling! Same goes for dairy farmers!
“Stop eating meat.
When you eat it, you’ll end up looking like the Animal it came from.”
He great
Im now scared straight !
Wow! Information overload. This doctor spoke SO quickly and had so much info that I had to stop halfway through to calm my brain. Not sure yet if I'll finish watching. If i do, i need to watch on a computer instead of my phone so I can read all the info on his slides. Not too sure how I feel about his body parts nicknames. At least they weren't crude; thanks for that.
Love this content. May I refer to it on my channel? I AM the Healer 😊
Thankyou for such great information.
Would love his food additive talk ❤
Here's more studies that raise a concern about soy and breast cancer:
Zeng (2020) “Effect of soy intervention on insulin like growth factor levels: meta-analysis” phytother res, Jul; 34 (7): 1570-1577. Study showed that soy increased ILGF in humans. (This is of concern, b/c elevated ILGF has been associated with increased risk of diabetes and cancer). I don’t know how much it increased ILGF relative to other foods.

Velentzis (2008) “Do phytoestrogens reduce the risk of breast cancer and breast cancer recurrence?” eur j cancer, Sep; 44 (13): 1799-806. Says “Short term intervention studies suggest a possible stimulatory effect on breast tissue raising concerns of possible adverse effects in breast cancer patients.”
Thank you !!
Dr. Brook Goldner reversed Lupus with Flaxseed smoothies. Dr. Michael Greger's research says Flaxseed reduces PSI.🤔
This doctor is amazing!
Terrific coverage! Why would you eat food before drinking Reverse Osmosis water? Is it too purified, so pulls nutrients from body?
Yeah that's what he's getting at. Avoiding hyponatremia
“Skip the oily salad dressing and thou shalt look better undressed”
😂
The 10 commandments were spot-on! Good idea to make those rules into such a biblical learning.
The 8 is missing tho ;)
I always order my salad "undressed"😁 not me, only the salad...!
Heard consuming organic soy products are so healthy for oestrogen driven diseases such breast and ovarian cancer. The information about soy consumption has being a villain is outdated. New research says otherwise. It is a challenge to know who to believe now
I watch a lot of dr. Roger's video's and he's very meticulous in checking the science. I believe him when he says he advises against soy where others find it ok. I only consume it rarely now, same for flaxseeds (once a fortnight vs a spoon each day, till the package is empty).
I follow peter l find he is very very accurate about what he says so l try to do what he says including lowering or no flaxand chia seeds, they are also high fat. I am open to ideas we are all trying to be healthier and we want to avoid cancer so it's worth trying. Each of the plant based doctors advise different things, dut all are trying to help us be better health wise, they all mean well, take what you want from each one and apply it
@@karenstanton5405 For me it helps that Dr. Rogers is a big fan of Dr. mc Dougall who rose to the top of my plant-based-dr-list in no time. Next to that i also lean to what dr. Clement is doing with the sprouting (but so far i only make mungbeansprouts and lentilssprouts really, he's even sprouting nuts) and eating raw. I try to look at each ingredient and howlong it needs to be cooked (carrots and tomato do better heated), cut onions and garlic types 10 mins before cooking, 40 mins for broccoli and cauliflour, but try to keep things as raw as possible in my dishes (usually stews and dahls lol) Things like that. I also can't do dr. Roger's one meal a day thing, but i have 2 meals within a 10 hour window. I am sparse now with my soy and no longer use flaxseeds.
I’m so confused because almost all of the plant based doctors say it’s fine.
If corn is high in Mercury (mentioned at ~55:20), I guess my love of air-popped popcorn sprayed with apple cider vinegar and sprinkled with nootch is a bad habit. Bummer ! :-(
Have you discussed your opinion of soy with Dr. T. Collin Campbell? In recent interview with Chuck...- He said soy studies were negatively biased in past to encourage milk consumption.. See his recent interview. I Love your deep dive research!! Information is Power!
I continue to be so confused about soy and flaxseed. It is so hard to make an informed decision.
sharing on FB... I am grateful for this health information. Sincere thanks...
This is the first time, I've ever made a comment at this site. Do you want to question my academic credentials? I was student athlete of the year at Stanford. Had 99% board scores in medical school & residency (highest possible score). I was trying to be polite in the presentation, so I went easy on soy. I don't care about soy. It's the 2nd most estrogenic food, after flax. Soy is worse than suggested in the lecture. You tube channel "Dr Anthony Jay" is run by a Phd biochemist, expert in lipids who has videos on soy and other estrogenics. He is much more critical of soy than me. His book "Estrogeneration" recommends to avoid ANY food with soy in it.
I loved your lecture and I believe you and the science you presented! Thank you Dr.Rogers for sharing your knowledge with us!
I'm looking for your soy lecture at your site. I'll find it. After 1hr 55 min you get into soy - a real problem in my head. I'll post this talk there. Not as a link because I haven't figured out how to do it . I'm glad you mentioned other doctors that say soy is positive and why you think otherwise on a whole. Good talk Dr. R.
Lots of credentialed people write books. We must read and evaluate the literature. The book “grain brain “ is an excellent example
Your academic credentials are from 30 years ago. A lot of science changed over that time. Is T. Colin Campbell, PhD wrong in the China Study?
@@lebo1026 I guess you didn’t watch the entire video as he talked about the China study supporting what he is saying. Obviously, he is up to date on the science! Just look at the biochemistry he shared!
Dr Rogers
Im pretty sure ive heard at least 1 other WFPB Dr say that he too would reduce bean consumption...plant protein ..with cancer diagnosis.....Dr McDougall was one and for some reason i think i heard Dr T Colin Campbell make some comment about that too....?..on video?....so yeah...there ARE others who would agree with you ❤
I'm perimenopausal and my sex drive has nose dived! Looking for ways to naturally increase estrogen...
Very interesting presentation. I have three questions: I heard high testosterone levels accelerate aging. Dr Rogers likes to increase his testosterone level but this might not be so healthy after all. Regarding flaxseed: dr Jelinek from Overcoming MS promotes flaxseed oil for MS patients. Would this be an exception? Some studies suggest flaxseed is good for prostate health as well. Quite confused on this topic. Aluminium in water is scary, are swimming pools ok or are they messed up with chemicals containing aluminium to make them look sparkling?
Dr. Rogers - if a man had his prostate removed and now can no longer have erections, what would you suggest? Are there any doctors, clinics, books, resources or lifestyle practices (e.g., fasting, etc.) that you would recommend? What would you do to facilitate recovery from this symptom? He is not plant-based at this time and does consume alcohol.

Here's more papers expressing a concern about a possible role for soy in breast cancer.
Duffy (2007) “Implications of phytoestrogen intake for breast cancer” ca cancer j clin, 57: 260-277. Says “There is very little human data on the role of phytoestrogens in preventing breast cancer recurrence, but the few studies conducted do not support a protective role.” Says, “several studies have indicated phytoestrogens could play a stimulator role in breast cancer growth.” Says, that at “physiologically relevant levels, genistein stimulates estrogen receptor positive tumors, while at higher (> 10 micromol/L) concentrations, genistein appears to be inhibitory. This atributed to estrogenic properties being predominant at low levels, while at higher levels, other anticancer actions of phytoestrogens predominate… but that “plasma levels of over 10 micromol/L are difficult to achieve with dietary intake.” Article says “Women should be advised against claims that soy is a “safe” estrogen product. And that “processed [soy] products may have detrimental effects compared with soy flour and tofu (sources most commonly consumed in Asian countries… the consumption of high dose isoflavone supplements by women at high risk or breast cancer survivors cannot be recommended. Several recent reviews are in agreement with this recommendation.”
Duffy (2007) “Implications of phytoestrogen intake for breast cancer” Sep-Oct; 57 (5):260-277. Says “There is in vivo animal data suggesting the phytoestrogen genistein may interfere with the inhibitive effects of tamoxifen on breast cancer cell growth.”
Think Chef AJ froze only not the doctor.
This doctor presentation style is too fast and too reference and quote heavy. He lost me about 10 mins in.
He's the only one I enjoy listening to. 😅 Different strokes
@@lynnritchie231 so you'd like more of a slick conman style doc? He's being genuine. And he is the only doc I see in the comments section actually trying to help people and answer questions.
I've been eating whole none GMO organic black and yellow soy beans to help lower a reoccurring hormone positive breast cancer. So, should I stop doing this?
I would stop this immediately. Please watch Dr Rogers other videos of the estrogen dangers of soy products. Wish you the best with your diagnosis ❤
Here's some studies that suggest a reason to be concerned about soy and breast cancer.
Allred (2001) “Soy diets containing varying amounts of genistein stimulate growth of estrogen dependent (MCF-7) tumors” cancer res, Jul 1; 61 (13. Soy with increased growth of HUMAN breast cancer cells (MCF-7) in vivo.
Allred (2001) “Dietary genistin stimulates growth of estrogen dependent breast cancer tumors similar to that observed with genistein” carcinogenesis, Oct; 22 (10): 1667. Glycoside genistin, like the aglycone genistein, can stimulate estrogen dependent breast cancer cell growth in vivo. Removal of genistin or genistein from the diet caused tumors to regress.
Mueller, Stefan (2004) “Phytoestrogens & their human metabolites on estrogen receptors ER alpha & ER beta” toxicol sci, July; 80 (1) 14-25. This paper is often cited by people claiming that soy only significantly activates ER beta receptors (b for beneficial). But if one actually looks closely at the graphs, there was also a lesser, but similar activation of ER alpha receptors (the bad one = a/w proliferation of breast tissue & breast cancer) (figure 2). The paper had 2 parts. In the 2nd part of the paper, the graph even showed one study where there was possibly more activation of ER alpha by genistein. (Other books I’ve read tend to say that ER beta activation > ER beta. But the point is that ER alpha is still activated) (figure 5).
Does it make a difference if the soy is organic?
Here's studies linking soy to infertility, in men. Giahi (2016) “Nutritional modifications in male infertility: systematic review” nutr rev 74, 118-130. Soy shown to “lower semen quality.”
Chavarro (2008) “Soy food and isoflavone intake in relation to semen quality parameters among men [HUMANS] from an infertility clinic” hum reprod, Nov, 23(11):2584-90. Mass General Hospital. Higher intake of soy foods and soy isoflavones is associated with lower sperm concentration = 41 million sperm per milliliter fewer.
Asians eating soy seems infertile? All China should do is give men soy instead of choosing a one child policy.
Did they distinguish between organic vs gmo soy?
And tell this to the Chinese, before the one-child policy.
🥲
i love my soy yoghurt & flaxseeds in my blend, as well as tempeh & tofu
