It describes the main types of epidemiological studies and their relationships, strengths, and weaknesses; the nature of epidemiological measurements; the relationships between diet and health at international, national, household, and individual level; concepts of validity, reproducibility, calibration, bias, and confounding; and distinguishes between bias, confounding, effect modification, and interaction. Finally, it covers interpretation of findings, systematic reviews and meta-analysis.
