... that the survey methodology yield satisfactory estimates of the usual nutrient intakes of the group. ~ -Dissenting statements prepared by individual members of a committee are not subject to the normal National Research Council review processes, nor are they subject to committee or staff editing or review.

... Since the estimated mean requirement for nitrogen balance may vary by as much as 50% depending upon the experimental protocol, particularly the prior diet of the individual subjects, it is apparent that the error term must be large and one must assume that the true biologic variation is relatively small. In all estimates of the variability in nutrient requirements derived from compilation of values in the literature the error term must be similarly large since the experimental protocol, background of the subjects, etc., differ.

... The recent analysis of the extent of iron deficiency in the American population for the NHANES data indicates that the probability approach overestimates the extent of the problem. Currently available information on the nutritional status of Americans and recent developments in nutrition inevitably shift the interest in dietary surveys and how they should be interpreted.

... No doubt this is desirable, but given the fact that nutritional deficiency does not appear to be a major public health issue, it is quite unlikely that such research can be a national research priority except for a few nutrients. Thus it seems unlikely that the necessary data required for more accurate application of the probability approach will be available any time in the near future.

... It is certain that a substantial part of the survey population will underestimate their individual average intake either because of error or because the two or three days derring which intake is measured were atypically low. When nutrient intakes vary greatly from one day to the next as they do in the U.S., often 100%, it is inevitable that a substantial number of atypical intakes will be recorded.

... The probability approach gives the impression that the estimates of undernutrition are rather precise since the utility of the extensive statistical calculations is not apparent otherwise. The identification of such "problems" will presumably call for public health solutions.
