World Food Policy Supermarkets can contribute to population weight gain through the sale of sugar-sweetened beverages, and other highly processed, inexpensive foods that are major “vectors” of sugar, fat, and salt in transitioning Asian countries (Baker and Friel 2014). Major food processing companies have been shown to increase their profits by making and selling processed rather than unprocessed foods (Stuckler and Nestle 2012). Internationally, supermarkets are implicated in over-nutrition and micronutrient deficiencies in lower middle income countries (LMIC) (Gomez and Ricketts 2013). The evidence is mixed however, with an association between supermarket shopping and unhealthy food consumption observed in Guatamala (Asfaw 2008) but not in Tunisia (Tessier et al. 2008). In Indonesia, supermarket shopping is associated with overweight and obesity in children living in high income households but not in adults (Umberger et al. 2014). In contrast in Kenya, supermarket shopping was associated with unhealthier weight in adults but reduced underweight in children and may be related to consumers’ initial nutritional status (Qaim et al. 2014). The precautionary principle is used to invoke the prevention of harms to health even when the evidence of risks is inconclusive and it has been advocated in response to the influence of multinational food companies (Stuckler and Nestle 2012). It can also be applied to the effects of large national and international food businesses as they influence food producer decisions and their cultivation practices. In the case of the food retail transition, application of the precautionary principle would support the protection of alternative sources of fresh food, rather than allowing food purchasing to become concentrated by a few conglomerates which offer less healthy retail environments. It is particularly relevant in this context because, although the diets of those purchasing at modern retail formats are likely to be less healthy than those of traditional food markets shoppers, poor health outcomes take time to appear. International research indicates that the dietary and health effects of the transition to supermarkets depends greatly on the pre-existing food system and on broader social, economic, and political conditions, such as urbanization, sedentary working conditions, carreliance, and increasing female employment among others. Nevertheless, the food retail system is influential; the Thai population has gained weight (Aekplakorn 2011) as the number of modern food retail outlets, including convenience stores, has risen (Kelly et al. 2010). Thai supermarkets reached annual compound growth rates of 16% between 2001 and 2009 (Reardon et al. 2012), and packaged foods from modern retail have increased in sales by 65% over 15 years (Ng and Dunford 2013). In modern western countries supermarket growth has been linked to a decline in small farms, and the growth of agri-business which has come to dominate food retail (Wiskerke 2009). Thailand’s major supermarket chains are using many of the same strategies as those adopted by Western supermarkets to capture market power (Dixon and Banwell 2015). Currently, supermarkets in Thailand procure fresh produce in 57
