Abstract
Department of Epidemiology and Biostatistics, Tbilisi State Medical University. The paper contains definition of the nutritional epidemiology. A short summary of essential methods used in the field is presented: detailed diet records (food diary), food frequency questionnaires, 24-hour diet recall, nutritional biomarkers. Their application modes are given. Advantages and disadvantages of the above-mentioned methods are stated. Main disadvantages are biases, confounding, inaccuracy, motivation and education requirements, cost and duration, etc. The main challenges of nutritional epidemiology as well as the modes to overcome them are presented as well.
