I didn't initially want to write this post, but after long and hard contemplation, I realize I just can't hold my tongue on this topic, and I feel the need to point some things out. But before I get into what I want to say, I just want to state that I don't write any of this in a mean spirit, so I hope no one takes it as such, especially Ella!!
Ella, I understand that you are very biased against certain herbs used for NBE and you certainly have great reasons to be due to your individual sensitivities and also personal convictions, so I'm not going to waste my time, neither yours, in trying to pull you aboard the herbal bandwagon. I think your personal choices are your own, and everyone should want to research, form their own opinions, and then choose their own NBE path because as we all know, not everything works for everyone.
With that said, besides the clear differences in wealth and poverty between certain countries which will indeed effect something like breast growth, most of everyone is also forgetting the differences and implications that cultures have on such things as these. A study of anthropology would showcase this immediately: Different cultures have different perceptions of beauty and it's important not to view these things with an ethnocentric mindset. For instance, I was talking to my friend once about how bras have actually been studied to contribute to long term breast sag. She immediately and rather ignorantly pointed out that people in African countries are often depicted with long saggy breasts and they don't seem to wear bras. SIGH. What she forgets is that beauty standards are different there and culture plays a huge part in these things. If you're interested, I'll point you to an excellent article that explains why cross-cultural beauty examinations are ignorant and insensitive on this bra debate topic:
http://www.thelingerieaddict.com/2013/11...gging.html If you read the article, you'll see that many of those points can also be applied to this line of thinking posed on this thread. I'm not saying this to demean this thread or as a personal attack on you, Ella, so I hope you don't take it that way at all, but I do say this to point out some apparent ignorance (and I'm not saying that meanly, I'm saying this with literal meaning. We are all ignorant on some level, after all).
So going back, as a person who is from a multicultural family, and who was raised on solely an Asian diet, I can say that while Asians do tend to eat more soy products than Americans, we are not sitting around gorging ourselves on tofu, especially not with any mind to grow our breasts. Pointing out that Asians consume more soy than any other country and therefore should be expected to have bigger breasts, is not taking into consideration how soy is consumed within a diet, nor how that relates to a functioning NBE program. I'm pretty certain the same could be said for the other countries that you mentioned, as well. Considering that Americans don't tend to eat soy at all or in rather low quantities, an Asian who ate soy 2 to 3 times in a week would largely be considered as more than most average Americans, but is that to say that it is enough to grow breasts and is it logical to compare that to an NBE program?
Going back to specifically culture, to say or even expect that women from these countries should have bigger breasts is to normalize the Western standard of beauty while demeaning and making inferior these countries own personal perceptions of beauty. Yes, women in America might be high on the list for a country with bigger breasts
BUT that is largely due to our countries standard of beauty that advertises and promote bigger breasts on women, which in turn: makes women want their breasts bigger. So women will do things such as NBE or get breast implants or fat transfers or whatever they can do to increase their bust size, and this is something that will inflate the average size of women's breast in America as well as other countries. Some of these countries do not put as much emphasis on bigger breasts on a woman as a standard of beauty, and in a lot of Asian countries, in particular, smaller breasts are seen more appealing and desirable. Women in Thailand might consume more PM than women in USA but that's not to say or imply that they are doing so for bigger breasts. Also, once again consider, most American women have never heard of PM, so a woman from Thailand who drank PM tea once or twice a week would certainly be a lot more than a woman from the US might consume, but once again: is this enough to grow breasts, especially when that probably is not even their aim for consuming PM?
Speaking of breast implants, let's talk about how that effects some of these countries with bigger breast size averages. Most, if not all, of the countries that have bigger breast sizes are on the same list as countries with most breast implants per capital (look it up!), and I should point out that the average breast sizes in different countries are not limited to just women with natural breasts.
I hope you can see and understand how this is really futile. It would be as if I posed the question why do Americans have bigger butts compared to Asians or any other country and then trying to connect it with our diets alone while completely forgetting the differences in culture, wealth, and also standards of beauty and how that will influence women to achieve bigger butt sizes (and also the rise and desire to have Kim Kardashian butts in America, lol).
I think that how something is consumed and not just how much, is of significant importance and relevance in terms of NBE. If I took a small amount of PM every day, let's say PM tea, should I expect my breasts to grow in a years time? I don't think that answer is a firm yes. You can theoretically take an NBE herb every day for years, but if the dosage is not high enough to actually affect hormonal changes in your body, it will more than likely have no impact in terms of breast growth (if that is even your goal). Also, committing to an NBE program (which is what we are all doing for the most part) and following it, is very different from just having something naturally be a part of your diet (which is true for many of the countries you have listed).
Lastly, I think that it's a rather moot point to compare breast sizes with certain herbs and the places they are largely consumed in because as we all know, NBE herbs work differently for different people. As an example, PM may not work for everyone, but it has been widely shown to work for a lot of women as well as men and I think that isn't something that can just be overlooked because Thailand women aren't the bustiest of women. Same goes with other herbs you may have listed. Just because the countries that most widely consume an herb isn't as well endowed as some would expect, doesn't render the NBE success stories we have on this forum as well as on other forums worthless. So the question here isn't "Why do women try *fill in the blank* for breast growth when it doesn't work for women who consume it largely in their native country as part of their diet?" because clearly it does work for some people who are specifically on an NBE program, and as I've already mentioned, dosages matter when taking herbs. High dosages doesn't mean more effective, and low dosages never will be effective. High dosages as well as not cycling seem to be the main culprit for the ugly side effects of some herbs, and that is rather common knowledge here. Personally, I have built a considerably large list of my own favorite PM success stories, of women who have kept their growth (and have stated so), so that's not a question either. But I do think stopping an NBE herbal program too soon can result in a loss of growth, just like with Noogleberry, and also, everyone is different so how a herb effects someone long term is of course going to be varied (definitely worth repeating).
I know I've probably written this out rather bluntly, but I assure you that I do so with no ill-spirit, but only to inform and illuminate some of the flaws in your logic as well as the ignorance in your questionings. I just hope that you don't take any offense, because truly that is not my intentions nor desire, but I do hope that you try to understand my points and where I'm coming from in saying all this.
