This paper verifies hypothesis of the food consumption dependence on a level of the country economic development. The level of the development is measured in terms of Gross National Product per capita and year. Based on the cross sectional data for 50 developed and 116 developing countries, lin-log regression models are estimated to investigate the dependence per capita dietary energy, intake of animal and vegetable energy and consumption of meat, milk and milk products and cereals on the GNP. In the models, dummy variable and interaction term were included. The results from analysis showed that per capita dietary energy and the intake of vegetable origin energy depends only on the level of GNP per capita and does not depend on the group of countries. Intake of animal product energy was statistically significantly dependent on the level of GNP. The average level of their intake is significantly different in the two groups of countries. It is characteristic for the consumption of both animal commodities: meat, milk and milk products. The cereal consumption is different for the two groups of countries. In developed countries, can be classified as inferior goods as their consumption significantly decreases with the increasing level of GNP. Developing countries whilst in the changes in cereal consumption with a variance of GNP were not evident.
