Re: debate
Here is my friends counter to your post.
Re: This is why the body synthesizes what it needs from linoleic acid. But too much arachidonic acid clearly promotes inflammation, which among other things can lead to conditions such as heart disease.
I seriously doubt it. China Study showed that if consumption of arachidonic acid were significantly contributing to heart disease then the trend line for all vascular disease on the bottom graph here wouldn't have had a downwards slope! Raw correlation between ischaemic heart disease mortality age 35-69 (tag M063) and dietary animal fat consumption (tag D053) is also strongly negative: -32%, that is statistically significant (marked by * in the doc).
The original document with these correlations can be downloaded from Oxford web site , see page 223. You may notice the same downwards trends if you look at the
Rheumatoid Arthritis (tag M061), and other inflammatory disease statistics. More animal protein or more animal fat equals less disease in China (except for milk!). More plant food especially wheat = more disease! The trend is very clear-cut and hard to miss.
