The research of food preferences has, besides a sociological aspect, an economic aspect and is a good starting point for estimating the willingness to incur expenditures on the consumption of individual products. In the paper, the authors compared food preferences on the Asian market for 9 product groups. Due to the complexity of the problem, the study included 17 selected countries of Central and Southeast Asia (China, Mongolia, Japan, India, Thailand, Indonesia, Kazakhstan, Uzbekistan, Tajikistan, Malaysia, Myanmar, the Philippines, Pakistan, Cambodia, Vietnam, Laos, Sri Lanka). The research was carried out on data from 2001 to 2013 with the use of the methods of gradual data analysis. In some countries there were no major changes in nutrition and food consumption, which can be explained by the stabilized political and socio-economic situation. The best example is Thailand.

The paper attempts to compare European Union countries in terms of the dynamics of changes in the value of lamb meat imports in the period 2003-2017. The standard against which this comparison was made was the average value, which should be understood as the growth dynamics of the examined feature for all EU countries together. For this purpose, tools related to the so-called Grade Data Analysis, such as the index of the unlikeness of structures “ar” (in this case a good tool to determine the direction of changes and the speed of these changes for all EU countries) and overrepresentation maps (used to visualise these changes and for their interpretation). Additionally, with the help of GDA methods, EU countries were divided into groups characterised by smaller, medium and higher dynamics of changes in lamb imports. It can be concluded that the most dynamic growth in imports of this type of meat is found among the newest EU member states. This may indicate a change in dietary preferences in these countries. It may also be related to greater accessibility to goods previously considered as luxury, greater awareness of so-called healthy foods and the improved standard of living of societies that have joined the European Union.
