The literature expresses concern over the fact that increasing dietary LA can potentially enrich tissues with AA due to their metabolic link. The results of this study do not support this concern. Whereas AA levels in blood phospholipids is increased by GLA (gamma LA) or AA supplements, intervention studies bring no evidence to suggest that changes in dietary LA will modify tissue AA content in an adult population consuming a Western-type diet."<br /><br />However, seed oils were not a substantial part of ancestral diets, as far as I can tell, so avoiding them seems unlikely to do harm (and may do some good for reasons yet to be fully explored and explained).Chris Tunstallhttps://www.blogger.com/profile/15524207191133093112noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-4172244739328441442011-09-12T04:52:56.593-07:002011-09-12T04:52:56.593-07:00"As there is already too much misinformation ..."As there is already too much misinformation on the internet, I've taken the post down."<br /><br />Well, you are aware that referencing any one of your posts is asking for a possible inconsistent entry (or <a href="http://perfecthealthdiet.com" rel="nofollow">book</a>) in a near future, aren't you?

Of course that could change. But right now I think Willet might be right, LA is not inflammatory.<br /><br />I certainly agree with the others that the effects of LA depend on the context of consumption. Foods rich in LA (e.g. nuts) have a different effect from extracted oils rich in LA, largely because of innumerable other phytochemicals present in the whole food.Don Mateszhttps://www.blogger.com/profile/00920822445922261857noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-41902581578444992902011-09-03T20:58:05.383-07:002011-09-03T20:58:05.383-07:00Hi Stephan,

I think any food component taken out of context can be a bad thing. Too much antioxidant vitamins can be deleterious in a variety of ways.<br /><br />As for the other chemicals in nuts - I think small amounts of phytochemicals (to lump them together) can have pharmacological or (as Stephan has posted) hormetic (sp?) effects. In large doses, yes, they are nearly all - or perhaps all? - toxins.<br /><br />For a while I got freaked out by the "vegetables have toxins!" as well as "fruits have fructose *and* toxins!" warnings. I decided those are two food groups I am willing to take my chances on. I'm trusting our body has generally learned to deal with - and use to best advantage - stuff we've been eating for hundreds of thousands of years. Yes, I know, I know with the cultivated year-round fruit, but I have just not seen *any* study showing anything bad happening, but rather, often good things happening, with regular fruit consumption. I have scrubbed PubMed for anti-fruit evidence, but haven't found it. Certainly, if it makes a person feel bad, they shouldn't eat it.<br /><br />Going back to my argument about n-6 oils in their natural packaging vs. refined oils - even if the body doesn't use the plant's own protective chemicals, at least they are protecting the oils in the plant until consumed. All manner of unpleasant things can happen with refined vegetable oils, and adding Vitamin E or whatnot are added back later may not help. Like any commercially refined food.<br /><br />I think if you're looking for evidence against eating nuts and seeds because of their n-6 content, you'd have to look at the evidence from actual consumption, not theories about the components of the nuts. (From your comment I think you'd agree?) I've seen mostly good things about nuts, but I haven't really dug into the abstracts & studies, like I did with fruit. Maybe because my kids eat fruit, but one's allergic to nuts. ;)Helenhttps://www.blogger.com/profile/14504810823521044641noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-64340049317408371142011-08-26T10:18:07.106-07:002011-08-26T10:18:07.106-07:00This comment has been removed by the author.Helenhttps://www.blogger.com/profile/14504810823521044641noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-65628056090519464412011-08-25T23:49:53.905-07:002011-08-25T23:49:53.905-07:00I wasn't trying to convince you BTW, It's ...I wasn't trying to convince you BTW, It's a question for experiments to decide, not loose and woolly arguments.Sanjeevhttps://www.blogger.com/profile/09522727136330797375noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-4679566339579203022011-08-25T23:42:05.252-07:002011-08-25T23:42:05.252-07:00Helen wrote ...

I guess what I'm asking is WHO was included in these studies over time? Caucasian Americans, mostly men, women, etc.? Or did they start out with the latter and shift to studies conducted primarily in SE or E Asia? Just trying to understand a potential source of variation among the studies you've included in your graph. . .Bedpost-Twinklinghttps://www.blogger.com/profile/06578425427507859593noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-82099482973358021222011-08-25T13:20:19.810-07:002011-08-25T13:20:19.810-07:00So.

Different length fatty acids have different calorie content. Add to that that it takes 5-10% of the energy to digest the fat (more energy to digest protein, less to digest carbohydrate).<br /><br />2) What about hexane? Cheap seed oils are extracted with hexane. Hexane doesn't seem to accumulate in humans (see studies on shoe gluers) but it could extract all sorts of interesting compounds that might never disassociate from the indigestible fraction otherwise.Bastardhttps://www.blogger.com/profile/04773584479244051660noreply@blogger.com
