\begin{abstract}
\normalsize{
Thailand, Laos and Vietnam have developed at different paces in spite of being located in the same geographic corridor in Southeast Asia. While Thailand became an upper"=middle income economy, Laos and Vietnam remain in the lower"=middle income group. Also, the social outcomes have improved in these countries although at different rates. In this regard, this study aims to better understand the nutrition transitions in the process of development and draw conclusions about the food security and nutritional status among rural households. Accordingly, we explore food consumption behaviours across different segments of this corridor using three sets of measures: (i) per capita food expenditures, (ii) per capita calorie intake, and (iii) food consumption diversity. Furthermore, nutritional outcomes, measured by means of z"=scores of the common weight"=for-age for children and body mass index (BMI) for adults are also examined. The analysis is based on a 2013 dataset from rural household surveys of around 2000 households in three provinces, namely Ubon Ratchathani in Thailand, Savannahkhet in Laos and Thua Thien Hue in Vietnam. By employing a Tobit model and an instrumental variables (IV) approach for different groups of age (children vs. adults), income (poor vs. non"=poor) and nutritional outcomes (underweight vs. normal weight vs. overweight) we determine the factors that influence the nutritional status of the study groups. Also, geographic capital and poverty status across this corridor are explored with special interest. Furthermore, the interpretation of the cross"=section data can also be done in a time period manner by comparing districts with different wealth status and identifying differences across provinces and countries in the factors that underpin this process. The districts can be associated to different stages of development. Hence, the paper can provide important policy lessons for developing food security strategies for both, low income countries and emerging market economies and thereby help governments to avoid food insecurity traps and the prevalence of malnutrition.}
