Methods for determining nutrient requirement in pregnancy--I

HH Sandstead

There are several methods for evaluating nutritional requirements. Under appropriate circumstances, all can provide useful information. The most precise methods are those in which subjects live under controlled conditions. None of the methods is foolproof. The cost increases with the degree of control. Therefore, less expensive, less precise methods, may be appropriate for preliminary studies. If preliminary findings are positive, more carefully controlled studies should be done to obtain definitive information.
