Take a look at Tripping Lightly Down the Prostaglandin Pathways.
Omega-6 pufas result in the production of Series 1 prostaglandins (anti-inflammatory) and Series 2 prostaglandins (inflammatory). Omega-3 pufas result in the production of Series 3 prostaglandins (anti-inflammatory).
Now, see Are diets high in omega-6 polyunsaturated fatty acids unhealthy?
"Insulin sensitivity might be the common factor relating disease to fatty acid metabolism — both within and between the fatty acid pathways. A high linoleate to arachidonate concentration occurs in insulin resistance, in diabetic complications and also in some tumours."
"Current epidemiological and clinical evidence supports the regular consumption of cold-water fish as part of a balanced diet, in which attention to lifestyle and the quantities eaten (to prevent obesity and the insulin resistance syndrome) may be more critical than the nature of the fatty acids consumed."
Do you see where I'm going with this? If you have insulin resistance, don't change your diet (low in carbs & avoiding omega-6) to suit the insulin resistance. Tackle the insulin resistance!
This isn't an open invitation to start guzzling high-pufa oils. Stick to oils that have been squeezed out of things that grow in hot climates. I include Extra-Virgin Olive Oil in this category. Check the label, as the pufa contents of different EVOOs vary. Solesta from Aldi contains only 6.6% pufas.
EDIT: In addition, your brain depends on omega-3 to function properly. Too much omega-6 can "fry" it. See Mental Health and Omega 3/6 Ratio, A New Review.
Vitamin D is anti-inflammatory. Fish oils are also anti-inflammatory.
I just spotted this on Anthony Colpo's Blog: The Adventures of Chris “Razzi” Razwell and Other Assorted Internet Psychos. Oh, my!
And finally: I made mum a CD of "Dare" by The Human League (I bought it in vinyl years ago) and played it on the CD/Record player in the lounge at the nursing home. She loved it and was moving her arms in time with the music. This is her favourite track from that album.
