The last line of the conclusion:
"In conclusion, adding both DHA and ARA when supplementing infant
formulas with long-chain polyunsaturated fatty acids supports visual and
cognitive development through 39 months."
conflicts with the previously stated results:
"When the infants were reassessed at 39 months using age-appropriate
tests of receptive and expressive language as well as IQ, visual-motor
function and visual acuity, no differences among the formula groups or
between the formula and breastfed groups were found. The 14-month
observation thus may have been a transient effect of DHA (without ARA)
supplementation on early vocabulary development or may have occurred by
chance."
Additionally, the statement:
"The absence of differences in growth achievement adds to the
evidence that DHA with or without ARA supports normal growth in full-term
infants."
This is not correct, or at the very least, is quite biased. A more
accurate assessment would be:
"The addition of DHA with or without ARA does not appear to inhibit
growth in full-term infants."
There is no evidence given in this study to indicate that DHA or ARA
"support" growth or development.

This research was skewed when the controll group was given the
experimental product.
Comparisons, to be valid, need to be measured equally to the Gold
Standard,human milk. Even if you couldn't find exclusive breastfeeders to
one year,feed human milk to one year. Not artificial breastmilk
substitute.
Since when is three months of breastfeeding equal to one year of
artificial breastmilk substitute?

I have read through this important article several times, and cannot
find justification for the last sentence in the abstract and in the
conclusion section of the paper: "In conclusion, DHA and ARA... support
visual and cognitive development through 39 months of age."
It appears to me that the gist of the article is that there is no
difference among the groups, and therefore it would seem there is NO
support for the assertion that DHA and ARa are necessary.

LETTER TO THE EDITOR:
I read with interest and then confusion the article by Auestad, et
al, 1 a follow-up study of infants fed formulas containing long-chain
polyunsaturated fatty acids to one year of age who were assessed at 39
months for visual, cognitive, and language development. The infants in
the study were divided into four groups: control (unsupplemented
formula), breast fed, supplemented formula with DHA, and supplemented
formula with DHA and ARA.
The results of the study were clear-cut. As Auestad correctly states
"when the infants were reassessed at 39 months using age-appropriate tests
of receptive and expressive language as well as I.Q., visual-motor
function and visual acuity, no differences among the formula groups or
between the breast fed and formula groups were found".
What troubles me and what I found confusing was the authors'
concluding statement "providing both DHA and ARA when supplementing infant
formulas with long-chain polyunsaturated acids supports visual and
cognitive development through 39 months". The results of their study
indicate otherwise. In my opinion, this last sentence is at best
misleading.

After reading this publication three times, I have to throw my hands
up in
disgust. The Conclusion is completely contradictory, and that the AAP
publishes
such a flawed study is laughable! I came to this article because it was
cited in a
June 1, 2003 article in the New York Times about formula additives. I
don't
know who is more at fault: the study's authors for its myriad flaws, the
AAP for
allowing its publication, or the NYT for citing it.
I asked my 10th graders to read this study and give me their
feedback, and they
universally agreed that the conclusion was flawed. Several were also
concerned
that an industry rep (with competing interests) was on the research panel.
