This paper provides non-parametric estimates of the relation between nutrient intake and age for Czechoslovak individuals, as a function of characteristics of both the individual and the household she lives in, on the basis of household purchases. Results show no significant difference between the age - energy intake profiles of men and women. The decomposition of this intake between carbohydrates, lipids (i.e. fats) and proteins shows a lack of balance in the diet in Czechoslovakia, but significant progress toward a more balance diet has taken place over the period. Finally, household characteristics such as the woman?s level of education, or household income, have at most a marginal impact on these profiles.
