Longitudinal methods are used to examine food consumption decisions by American women aged 19–50. The data set used is the 1985 Continuing Survey of Food Intake by Individuals collected by the U.S. Department of Agriculture, which is a six‐wave longitudinal data set gathered over the course of a year. The multivariate results give insights into how individuals make food group consumption decisions. In addition, the use of longitudinal data allows calculation of variance ratios that have proven to be useful in dietary research. Simulations are run to highlight the effects of important explanatory variables.
