Huge respect to people who do research
I'm a guy but i still eat soy nearly every day because i know it's healthy! Vegans have the highest testosteron levels 👌
Lichtblick I saw that article but it actually shows were the same because we also have more globulin which binds with free testosterone
Right on man! And this guy Scynable, it seems he is subscribed to this channel only to hate on vegans. Either you have way too much free time or you secretly want to become vegan.
Scynable Prevents cancer under 3-5 servings....promotes cancer over 5 servings.... I know the video you are referring to. It's not a checkmate.
Scynable you are thinking of soy protein isolate which is not the same as whole soy foods
Highest Testosterone Levels? At best they are the same, and that is because modern animal products are loaded with Estrogen, PCBs, and PBA. Otherwise Vegan hormone levels would be less
Benefits of soy is greater for women with early childhood soy consumption. One of the fist foods that Japanese babies are introduced to are soft tofu and soy milk. Most Japanese, especially those who live in eastern part of Japan (like Tokyo), eat natto every day for breakfast. Many still have miso soup with tofu and seaweed for breakfast and at dinner too. They eat soy throughout the day; for instance there might be okara (soy pulp) in lunch salad or even baked goods, also yuba skin is very popular. Japanese women still consume a lot of soy milk because soy milk is considered a "skin food" that would keep skin younger and more supple. How did they get nutritional information such as this? In Japan they have Shokuiku, which is nutrition education in public schools.
Early childhood and regular soy consumption are partly why in Japan and parts of east Asia the breast cancer rates are so low. Although recent years the rates of breast cancer in Japan is trending up due to increased dairy and meat consumption. Now when I go back to Japan I find it hard to eat out as vegan, much harder than here actually in terms of variety. For example even so-called vegetarian dishes there contain things seafood or meat stock.
"What happens if you give soy milk to woman in Texas." That's kinda funny; Barbecue country.
I just had a test come back with high estrogen level and I am post menopausal. My doctor asked if I was consuming a lot of soy. This is contrary to anything I've seen before. Is it not true that it also depends on the form and type of soy? GMO soy is sprayed with roundup, a known hormone disruptor. The Japanese mainly eat fermented soy.
You are absolutely correct, the soy that we get in America sucks. You have to eat fermented soy like you said that the Japanese eat.
great video, not easy to see how much this may help someone going through breast cancer fight.
Thank you💕 I was concerned about soy because of the different opinions I've read online. Now I can happily eat soy knowing that it's nothing but good stuff😘❤
Interesting. Cholesterol is used by cancer cells to make the estrogen fuel. Two things to consider after watching this video: consume non-GMO soy and eliminate the animal products.
Thank you Dr. Greger!
Amazing video, thanks a lot
This is great information! Thanks.
Also for me as a great fan of fitness and natural bodybuilding. In these sports the majority of people think they must avoid soy, because they fear their oestrogen level could explode. These facts show, that exactly the opposite happens. So thanks for this one!
👍🏼💪🏼🌱
What is DR. Greger's opinion on plant-based protein powders for post strength workouts drinks? Do we really need to up our protein intake to build muscle mass?
I have my concerns about soy because of GMO soy is filled with cancerogenic roundup pesticide and even glyphosate genes and also because the GMO soy industry has been blocking labeling so consumers cannot decide to consume non GMO soy
You can buy organic and non-GMO soy; these products will be labelled as such, voluntarily by companies knowing there's a demand for these things. My worry is more that organic fields can be contaminated by neighbouring GMO fields (for any GMO crop, not just soy; organic corn can be contaminated by GMO corn, etc.). We still consume these (soy, corn), but maybe less on account of this. It's terrible, what's happening to the world, to our food... More crops to be modified in the coming future (apples, potatoes, etc.). So long as it's only a minority of us that care enough to not buy anything supporting GMOs, we won't have any say in the matter.
I am a 52 year old women who recently had stage 1 estrogen driven breast tumor removed by lumpectomy. My margins are clean and cancer has not moved to lymph nodes. I have no doubt that my diet and lifestyle choices in my past did nothing to deter my cancer from progressing. Are there studies out there that have looked at the effects of treating women (with my cancer type) without radiation, without estrogen blockers but with an estrogen blocking diet and lifestyle? Just curious.
Hi I am 39 and in your same situation, I don't I did my lumpectomy and don't want to have a hormonal therapy, if we can discuss this it will be really helpful, God bless us all
Same here but no surgery yet. Looking for radiation and chemo alternatives in nutrition. Be well!!
I was diagnosed with the same: oestrogen driven breast cancer in Dec 22 at 56yo. No lymph node involvement. I had the lumpectomy, chemo and radio but I've refused to take letrozole for the next five years. I already have osteopenic hips. I have been vegan for 15 years but now eating an organic whole food plant based diet and leading a healthy lifestyle ie no alcohol, meditation, yoga, walking every day (which I've always done), trying to maintain my weight within the normal BMI range and limiting stress.I do everything that Dr Greger suggests re eating soy, mushrooms, broccoli sprouts, cruciferous veggies. I would be interested if there is any research out there too. i do not want the cancer returning!!!!
Same but stage 3 grade3. Had to do lumpectomy that margins didn’t work but refuse doing another lumpectomy, quimo, radiation, tamoxifen. Changed to organic diet, juice, detox, supplements, vegan, naturopathic Dr. And here 5yrs later🙏🏼 Use flax, chia and sesame seeds every day.
@@mirandawrites9311 have a look at IV C
good stuff!
Fantastic video!!!
I like eating dry roasted edemame to up my protein intake (50 grams of protein per 100 grams of edemame). Does anyone know if roasting the beans destroys any micronutrients?
Thank you Doctor for helping to spread the truth
Can we get a video on baobab?
I'm told by my oncologist- No Soy. It's so frustrating!!! Everyone has a different opinion. Who's correct ??
Help 🌺
I personally err on the side of caution and don't overdo soy, try to eat tempeh or edamame which are less processed. I had an ovarian tumor grow when I was consuming large quantities of tofu and soy milk. Dr Gregger also has a video in which he mentions soy increasing igf1 after a certain level of soy consumption.
What ever I reading I find that soya have estrogen or increased estrogen. Now I am confused. It is opposite of this research.
@@trkuljafoodhealthlife4804I like to see the studies and read the whole thing to know how they were done and on how many, etc.
What was the daily serving of soy milk? How much should we consume?
Do flaxseeds have the same effect? Also, would this effect acne in any way?
Jigglypoop97 yes I'm interested in how soy products affect hormonal acne
I don't eat soy. What other options would work in a similar way?
Today I saw an old french lady buy Soy Milk. (the vegan movement hasn't made it's way to France quite yet)
This happened in Germany, in Germany we have options if you are lactose intolerant and those were right next to it, but she clearly went for the soy and it wasn't the first time.
It made me happy and full of hope.
I would be really grateful if the topic regarding conjugated estrogen CREAMS (applied directly on breasts) and their potential link to breast cancer could be addressed. Although I have posted the same question in other channels before, I am yet to recieve interpretations. Can topical application on breasts really trigger breast cancer? I understand that it can cause breast tenderness albeit. I keep hearing about this potential breast cancer scare, but the teams fail to provide evidence. It would be so helpful to delve into the topic...
I feel like this is good news for men and breast cancer patients but considering how beneficial estrogen is in healthy women, is it really good for them to have their levels lowered?
If you are allergic to soy, what can be eaten to have the same effect?
So if someone has ms they shouldn't eat soy, seeing as pregnant women are always in remission due to high estrogen levels during pregnancy, is that right Dr. Greger?
Probably not. Nutrition is far more complex than we realize, and it's not uncommon for foods to have very different effects depending on so many factors. Soy in particular seems to have both anti-estrogenic and pro-estrogenic effects, depending on such a host of factors. What's encouraging is that the research so far seems to have shown that whatever effect is occurring, it seems beneficial to the host; i.e. the pro-estrogenic effects observed are beneficial to the consumer, and the anti-estrogenic effects as well. In other words, it won't lower or raise your estrogen in a way that has bad health effects. This is all assuming normal consumption levels, of course, not getting half your daily calories from soy or anything extreme like that.
+Back Space Thank you very much!
Rebecca stoner doesn’t have MS anymore because of a oil free, whole food plant based diet. See her page - just eat plants.
There is another nutrition facts video somewhere where the phytoestrogens in flax and soy etc have a positive effect either way (reduce bad enhance good) so I would go for it. It’s like how the veges only fight cancer cells and leave the normal ones. divine hey
@@backspace7124 High levels of estrogen are directly linked to breast cancer especially.
Another great video in favor of soy! Soy is good for you. The evidence is there in the research studies and in the health of millions of Asians that for decades have consumed this legume and are healthier than us! I wonder if they worry so much as we do about this plant.....
How much soy milk then should a woman consume say per week to reap the benefits?
Scynable what about fermented soy for men
what food has fermented soy?
Scynable thank you for your quick response
Michele du Toit Iiii
To answer your question: The studies had the participants drink 400ml(13.5oz) of soymilk per day for 8 weeks, the amount of isoflavones consumed was 109mg per day. Studies have shown as little as 50mg will also provide benefits, an 8oz glass of soymilk has about 50mg of isoflavones.
Isn't estrogen protective against heart disease though?
timtamore yes. Estrogen replacement is protective against the #1 killer of women - heart disease. It is also protective against osteoporosis and Alzheimer’s.
What about the damage associated with lectins?
A video was just done about that
Can you please talk about the connection between PCOS (inherited) and gluten? Some sites say not to have gluten when you have PCOS due to extra inflammation. I've been vegan for years and eat really healthy. Thanks so much
I was recently diagnosed with PCOS and have started taking an estradiol birth control. Do you think if I ate a lot of soy it would interfere with my hormones too much? I feel like I shouldn't block the estrogen since I don't have enough of it already, and I need it to balance out the androgen, right? I'm wondering about the gluten too, and also the whole complex/simple carbs situation. It astonishes me how almost no one knows what PCOS is unless they have it or know someone who has it, but it's so common and affects so many women. We need more education on it. Hope Dr. Greger makes some videos on it (or maybe he already has?)
check out his website u can search for it on there. theres a few :) if u look at his 'womens health' play list thats got some interesting stuff about saturated fat & estrogen
@TheMissCrocodile thanks :)
CUT OUT ZENO ESTOGENS, PLASTICS , PERFUMES ETC

How does soy affect women with pcos..those that have irregular cycle
have u watched his videos on the website about this? they r great :)
fyi only green soy or edamame not brown soy or commercial soy.
Osita onyebalu which one is green soy???
Do you think birth control pills can cause cancer?
How much soy milk were they drinking?
400ml(13.5oz) per day for 8 weeks:
www.ncbi.nlm.nih.gov/pubmed/9839524
www.ncbi.nlm.nih.gov/pubmed/11303585
wondering how to choose a good soy milk for this purpose...anyone?
Look for "organic" because most farmers use pesticides on soybeans. Also look in the ingredients for "whole soybeans" because some manufacturers just use soy protein isolate.
I like Trader Joe's Organic Original Soymilk, they use whole organic soybeans. It also has 50mg of isoflavones per 8oz, it says so on the package.
Silk organic soymilk tastes good but it doesn't say how much isoflavones it has.
Nice, much appreciated. Good info :)
Soy is amazing! If I could I would marry it
Well crap! My breast cancer loves to eat estrogen so I am doing everything I can do avoid it - especially not consuming soy in any form per my oncologist from Johns Hopkins.
I had consultation from Dr. Bruzinski. He sad I need avoid soy products because I have Her2 positive breast cancer.
take that soy bashers
Can you please address vaginal estrogen and it’s safety…
ha ha ...so awesome...
So, it is one of those things where you have to weigh the good and the bad with ingesting soy? So, it's good for women but all soy is allegedly GMO which means bad for everyone. Do you risk ingesting a GMO to prevent cancer?
Nicha, yes, I've heard all of these controversial things, it's GMO, it's not GMO. Do we really know? How do you know for sure?
Yes, I am very aware already of stores selling organic soy, pretty obvious. I guess you haven't heard that ALL soy and corn is GMO whether it's organic or not. That's the issue which brings me back to my original comment, how do we really know it's OK to ingest? You have to trust the organic symbol which I don't always. Organic is not foolproof especially with soy and corn.
urthebest1122
look for gmo free products; there are labels for that.
ofc you can never be sure though.
urthebest11221
I understand what your saying. Even though it's labeled non gmo,, where did it originally come from in the beginning, is it labeled correctly, I'm very skeptical so I just don't buy it.
why don't you start by providing evidence that 'GMO means bad for everyone'?
so if soy lowers estrogen... can you get hair loss then?
soy is good for women.. but not for men.. i wished u had mentioned that doc..
Jax Amilius
but he shortly mentioned the effects of soy in men - estrogen levels dropped, but it had no effect on testosteron.
Ella L true but it does reduce sperm count and can cause infertility :(
Jax Amilius
i heard that but i don't know if that's true... any links of studies?
Soy is good for women AND men. ;)
