In the Netherlands, excess body weight and obesity occur more commonly in certain ethnic minority groups. Diet plays an undeniable role in the development of obesity. Insight into the roles of diet and eating behaviour in the development of obesity among ethnic minorities is, however, limited. The migration histories, socio-economic statuses and socio-cultural environments of ethnic minorities are important determinants for eating patterns. It is important to take these determinants into account when treating overweight patients who are ethnic minorities.
