The results of study showed that all food groups except non-alcoholic and alcoholic group, are necessary for consumer, elasticity coefficient ranged between 0.670 for fish group, 0.391 for oils and fats group, and difference in time period (exchange rate liberalization) has a statistically significant impact on average propensity consume, and marginal propensity consume for each cereals and bread, dairy, cheese and eggs, oils and fats, vegetables, sugar and sugary foods, and these groups mostly consider sources of energy food for consumer, except dairy, cheese, eggs, vegetables, which indicate the consumer's tendency to energy food at expense building food (animal protein), perhaps due to changes in real income individual as a result of application policy exchange rate liberalization and its direction for cheaper foods expense building food, which affects negatively on nutritional status for consumer. Also, region (urban, rural) has statistically significant impact on average and marginal propensity of these groups, which may be due to decrease of employment opportunities in rural areas compared to urban, also decrease of agricultural income, which is the main source of income in rural, and consequent difference in the food pattern consumer in rural compared to consumer in urban, and non-provision necessary food needs. Group of food and drink, and other food products not classified under another item, and groups of non-alcoholic and alcoholic drinks, after addition dummy variable to second and third equation showed statistically significant effect of difference in time period that reflects impact of exchange rate policy on these groups
