Study: Womens' Breast Cancer Rates Lower In Mongolia Than China or U.K.

I came across this study by Troisi et al. accident.  Here's the introduction:

I was surprised by the report that the breast cancer rates in China and the U.K. are 3 and 10 times that in Mongolia.  Mongolian women eat diets very high in red meat and dairy products, much higher than in the U.K. or China.  This data might provide evidence against the idea that plant-based diets are best for prevention of breast cancer for women of Asian and European descent. Let's look at it. 

In this study the authors sought to study the hormonal differences between Mongolian and U.K. women.  The Mongolian women were "the mothers of school children attending two primary schools in Ulaanbaator, the capital of Mongolia."  100% of these women had children, and most likely, all had breast-fed their children extensively, although this is not specified by the report. 

In contrast, the U.K. women were "premenopausal Caucasian women from the U.K. who had been recruited nationally between November 2008 and September 2009 as controls for a case-control study on the genetics of breast cancer."  75% of these women had children, but only 78% of U.K. women had more than one child, whereas 92% of the Mongolians had more than one child.  

"Among parous women, about 22% of the U.K. women had one child and 78% had two or more compared with 8.5% and 92% of the Mongolians."
 Also, "The Mongolian women were younger, and of smaller stature and lower weight than the U.K. women."

 U.K. women have been called 'the world's worst' for breast-feeding rates.

The fact that the Mongolian women were younger and more likely to have done extensive breast feeding of more than one child is very important because earlier age of parity, greater number of children, and more extensive breast feeding are all associated with lower risk of breast cancer:

 Regarding diet, the Mongolian women ate much more meat and dairy than either U.K. women or Chinese women as the Mongolian diet "consists almost exclusively of meat and dairy products":

Table 2 of the study shows that in comparison to the U.K. women the Mongolian women ate on average 64% more vegetables (excluding potatoes), twice as much meat, one-third as much fish, 3.5 times as much milk, 5 times as much yogurt, 50% more cheese, and almost 2 times as much butter daily. 

This study also surprised me in its report that the Mongolian women had higher levels of both estrogen and progesterone, and lower levels of testosterone, than the U.K. women.

Unfortunately the authors of this report do not discuss the role of early and multiple childbearing and extensive breast-feeding in prevention of breast cancer or, very likely, the differences in hormone levels between the Mongolian and U.K. women.  I suspect that these factors play a much larger role in the low levels of breast cancer in less 'developed' populations than any modern scientist programmed by feminist ideology is willing to even entertain, let alone admit.

 As noted by the authors, this data adds to a growing body of evidence that elevated estrogen may not be a breast cancer promoter.  This data also contradicts the idea, which I have previously promoted, that all animal-based diets promote breast cancer to a greater degree than more plant-based diets.  The Mongolian women eat meat and dairy products from grass-fed animals.  It is well-established that the meat and dairy products from exclusively grass-fed animals have higher levels of omega-3 fats and conjugated linoleic acid, both of which appear to have anti-cancer effects.  Meat and dairy products from exclusively grass-fed animals also contain higher levels of phytonutrients derived from grasses, compared to grain-fed animal products, which may also protect against breast cancer if not other cancers as well. 

However, it is also important to note that Mongolia reportedly has the 11th highest heart disease death rate (261 per 100,000), about 2.6 times that of China (99 per 100,000) and 8.7 times that of France (about 30 per 100,000) (see rankings here).  One should not imagine that just because Mongolian women have a low rate of breast cancer, the Mongolian diet protects also against other degenerative diseases.

I would further add that this data may suggest that early childbearing, multiple childbearing, and extensive breast feeding may be more important in prevention of breast cancer than dietary factors.   That is not likely a politically correct perspective in this age when 'feminists' seem bent on denying that female biology is geared toward early and multiple childbearing, but it is consistent with human evolution.  It is safer in our culture to talk about diet, than about reproductive activity choices.  Feminists won't attack you for promoting either a plant-based or a grass-fed animal based diet, but they will get "triggered" if you even suggest that women are biologically and psychologically adapted to being mothers.

It is a basic principle of pagan (including Taoist) philosophy that to enjoy life, one should act in harmony with nature, not in opposition to it.  It is a simple fact that women are most fertile in their first 10-15 menstruating years (roughly ages 18-30 years) so they are biologically designed to have children early in life, not after spending 10-15 years going to college and establishing a professional career.   Women who wait to have children until they are in their 30s or later will generally have a harder time conceiving and breast-feeding, and according to pre-modern European and Chinese medicine concepts, their children will generally have less vitality, because the mother's body will not be at its biological peak when imparting life to the children.  A growing body of evidence indicates that late child-bearing is not only worse for the children, it is also be worse for mother's long term health.
