I don't know how quickly you can make changes with diet, but this link may give you food for thought.
Several sources suggest between two and three grams EPA and DHA (a derivative of omega 3 found in fish oil) a day (about 5tps but check the label), some as much as five. You might want to discuss it with your advisers.
There are lots of trials linking omega three to improved vascular health for what would appear to be sound reasons.
There are also severl links on this site you can search for. There are also a number of books on the subject. The author of the Zone diet published a book last year on the inflamatory aspects of diet.
Try searching on NCBI and enter the search terms. You could also follow the cited articles attached to the link below which leads in an "endless" chain of sub references.
We have all been and are bombarded by do this try that and it gest to the stage you dont know what to beleive. I only became full aware of this some months ago and am now passonate about it, and feel a huge indicanation that there is not a greater effort to expalin the implications of a failure to balance omega threes and sixes.
There is no easy way you just have to read some of the scientific literature yourself.
If there was ever one simple diet change that can potentially make a huge difference this is it balance your omega three and six. It helps in all inflamatory diseases, and eyesight, gums, mental health - there is a host of literature - try your local library for likely looking health books and check the index for "fats" and look for omega three six DHA EPA (you find it in lots of subjects depression, ahdh, macular degeneration, cancer.....)
I hope this helps.
