That emphasis on food displacement is something that you can see clearly in Weston Price’s writings.<br /><br /> Yes, I’ve seen that article on the Neanderthals, and blog comments on it here and there. <br /><br /> Most of the evidence up until very recently (2010, I think) suggested that the Neanderthals were not part of the human lineage. Newer evidence says otherwise, but there is still considerable debate on the topic, as far as I understand.<br /><br /> It seems that the modern orthography is “Neandertal”, as opposed to “Neanderthal”.Ned Kockhttps://www.blogger.com/profile/02755560885749335053noreply@blogger.comtag:blogger.com,1999:blog-8859456735165996893.post-46124030585659070082011-02-03T10:33:29.778-08:002011-02-03T10:33:29.778-08:00You're right, what you're calling food dis...You're right, what you're calling food displacement isn't often taken into account. (Although Taubes has referenced it obliquely in his dictum that "you have to eat something," and that eating less of one thing means eating more of something else.)<br /><br />Entirely off-topic, have you seen this snippet of info on the diets of Neanderthals?

Often the relationship between food A and disease D is not due to A causing D. It is due to A displacing food B, which is important in preventing disease D.Ned Kockhttps://www.blogger.com/profile/02755560885749335053noreply@blogger.comtag:blogger.com,1999:blog-8859456735165996893.post-87128326277055356852011-02-01T07:45:33.788-08:002011-02-01T07:45:33.788-08:00Ah, so many factors to untangle!
I've often w...Ah, so many factors to untangle!<br /><br />I've often wondered about the wheat vs. rice debate. Ignoring the gluten issue, might a lot of the difference be that we are usually comparing a flour to a grain? Wheat was originally eaten in many forms apart from flour.<br /><br />As far as vegetables in the diet go, I've always been a little concerned that a) we may be using the wrong metrics for counting these, and b) having a category like "vegetables" results in combining potatoes and spinach as if they are somehow similar.<br /><br />Nonetheless, this amounts to another excellent demonstation that the China Study data suggest any number of things not raised by the authors of that study!David Isaakhttps://www.blogger.com/profile/04928598446742324391noreply@blogger.comtag:blogger.com,1999:blog-8859456735165996893.post-83401734390024095072011-01-31T16:35:32.904-08:002011-01-31T16:35:32.904-08:00Hi Amber.

Since this is cross-sectional population data, the Excel formula can be used:<br /><br /> TDIST(ABS(R/((1-R^2)/(N-2))^0.5),N-2,2)<br /><br /> R is the correlation coefficient, and N the sample size. In this case, N is 113, and the Rs are the coefficients calculated by HCE.<br /><br /> Since HCE is designed to be used by single users, with small sample sizes of fairly uniform longitudinal data, the formula above cannot be used. It would wildly overestimate the chance probabilities.<br /><br /> Something to consider for version 2.0.Ned Kockhttps://www.blogger.com/profile/02755560885749335053noreply@blogger.comtag:blogger.com,1999:blog-8859456735165996893.post-18222037571989488222011-01-31T12:57:57.732-08:002011-01-31T12:57:57.732-08:00This is interesting, but I don't understand wh...This is interesting, but I don't understand where you are measuring statistical significance.

The problem with the older folks (at least in this sample) is that they probably ate less food overall, in which case the veggies could have crowded out more nutrient-dense animal foods.Ned Kockhttps://www.blogger.com/profile/02755560885749335053noreply@blogger.comtag:blogger.com,1999:blog-8859456735165996893.post-88965966553203569922011-01-30T10:03:43.351-08:002011-01-30T10:03:43.351-08:00Correlations with vegetables are too difficult to ...Correlations with vegetables are too difficult to dissect I think because it's so accepted that they are healthy. Of course people who go out of their way to eat vegetables are most likely going out of their way to do other positive things like avoiding candy/dessert and exercising. <br /><br />While I can't speak for every culture in the world, I know that in northern China, where the people seem to be perfectly healthy (on the outside at least--nice skin and teeth) on traditional diets of lard and duck fat, Western influence causes them to think their diets are unhealthy, which is a real shame (I think I read that schools in Thailand are trying to add more vegetables too).Johnhttps://www.blogger.com/profile/05161850700121191487noreply@blogger.comtag:blogger.com,1999:blog-8859456735165996893.post-29329844607129547602011-01-30T09:33:54.556-08:002011-01-30T09:33:54.556-08:00the blog world sure has done a deal on bashing veg...the blog world sure has done a deal on bashing vegetables lately, i guess i agree thoguh, there isnt anything inherently protective about them, in my opinion, but strongly think the inclusiion of oragns in the diet will have good lasting benefits. maybe as the older peoples bodies become more insulin resistant it is also changing their gut flora balance and showing the vegetables arent good for the 70-79 range?Anonymousnoreply@blogger.com
