GILBERT LEVEILLE: This is just a reaction. I thought it was a very exciting day. For those of us who have been away from the bench for a long time, it is exciting to see what is happening. The intriguing things to me are how the technology is evolving, and the tremendous number of things we can do with much greater efficiency than we could ever do them before.

Still, the issue that remains is the basic fundamental question that one poses to be answered with the new technology. It is interesting to look at the basic biochemistry that we are now able to explore in noninvasive ways, or at least with minimal invasion. But we still are playing the same tracer games when we chase a few carbons around a metabolic cycle, this is still fun, but I think it still leads us back to what questions we really want to ask.

Someone raised the question of whether what we really need to look at is what is happening at the membrane level and what impact that is having at the total organism level. Clearly that is an important question that we have not addressed, and we need to get to it.

The latest of a series of publications based on workshops sponsored by the Committee on Military Nutrition Research, this book's focus on emerging technologies for nutrition research arose from a concern among scientists at the U.S. Army Research Institute of Environmental Medicine that traditional nutrition research, using standard techniques, centered more on complex issues of the maintenance or enhancement of performance, and might not be sufficiently substantive either to measure changes in performance or to predict the effects on performance of stresses soldiers commonly experience in operational environments. The committee's task was to identify and evaluate new technologies to determine whether they could help resolve important issues in military nutrition research. The book contains the committee's summary and recommendations as well as individually authored chapters based on presentations at a 1995 workshop. Other chapters cover techniques of body composition assessment, tracer techniques for the study of metabolism, ambulatory techniques for the determination of energy expenditure, molecular and cellular approaches to nutrition, the assessment of immune function, and functional and behavioral measures of nutritional status.
