I will read the full article and come back but would make the following points;
1. I have previously posted trials / articles on this site which suggest that the only way fat intake can be accurately assessed is by biopsy etc. It was suggested that hidden fats posed a significant problem, and recollections etc may be open to question, and types of fats may play a bigger role than absolute quantity. ( I recall now the posts were in realtion to a reference to the nurses trial which from memory had similar conclusions - I will try and refind them)
2. It is suggested in may books etc that the problem is more about balance and quality than quantity. If the omega threes and sixes are significantly out of balance it causes potential problems. The bodies basic needs are fairly low. Somebody may be consuming margarine and "healthy" polyunsaturates high in omega six (corn soy safflower etc......) as part of a low fat diet, and still have a very poor ratio of omega threes to sixes etc.
Factors such as the above could have a high impact on any test results.
