Abstract
Purpose
The purpose of this paper is to assess the usefulness of nutrition labels in Thailand during nutrition transition from traditional to modern diets that increase salt, sugar, and calorie intake and to note socio-demographic interactions and associations with consumption of transitional processed foods.
Design/methodology/approach
The authors studied 42,750 distance learning Open University adults aged 23-96 years in 2013 residing nationwide and participating in an ongoing community-based prospective cohort study. The authors used multivariable logistic regression to relate nutrition label experiences (“read”, “good understand”, “frequent use”), socio-demographic factors, and consumption of four transitional foods. These foods included “unhealthy” instant foods, carbonated soft drinks, and sweet drinks, or “healthy” milk.
Findings
Overall, two-thirds reported good understanding and frequent use of nutrition labels. Unhealthy transition-indicator processed foods were frequently consumed: instant foods (7 per cent), (carbonated) soft drinks (15 per cent), and sweet drinks (41 per cent). Frequent users of nutrition labels (e.g. females, older persons, professionals) were less likely to consume unhealthy indicator foods. Those with the most positive overall nutrition label experience (“read” + “good understanding” + “frequent use”) had the best indicator food profiles: instant foods (odds ratio (OR) 0.63; 95%CI, 0.56-0.70); soft drinks (OR 0.56; 95%CI, 0.52-0.61); sweet drinks (OR 0.79; 95%CI, 0.74-0.85); milk (OR 1.87; 95%CI, 1.74-2.00).
Originality/value
Knowledge protected – those with most nutrition label experience were least likely to consume unhealthy foods. Results support government regulated nutrition labels, expanding to include sweet drinks. The study is remarkable for its large size and nationwide footprint. Study subjects were educated, represent Thais of the future, and show high awareness of transition-indicator foods.

Abstract
Purpose
The purpose of this paper is to investigate whether the food retail transition underway in Thailand, a transitional middle-income setting, is associated with increased consumption of processed foods high in fat, salt and energy. Such “problem foods” are important risks for avoidable cardio-vascular disease and diabetes burdens.
Design/methodology/approach
The source population were members of the nationwide Thai Cohort Study (TCS) followed since 2005 (n=87,151) for a study of the health-risk transition. For this report we used a multi-region sub-sample (n=1,516) of TCS members responding to an additional questionnaire about food environments, shopping patterns and food consumption. By using a TCS sub-sample we gained access to four years (2005-2009) of longitudinal observations on a wide array of variables related to health and wellbeing from an informative group.
Findings
Overall 85 per cent of the sample now have access to supermarkets; ten years ago the figure was 47 per cent, and when aged ten years, 5 per cent. Now half the participants regularly visit supermarkets and convenience stores, especially urban dwellers with higher incomes. Frequent shopping at supermarkets and convenience stores associated with consumption of six “problem foods” (soft drinks, snack foods, processed meats, western style bakery items, instant foods and deep fried foods). Frequent fresh market shopping was associated with increased vegetable intake. There was no association between food shopping and body mass index , diabetes or hypertension but supermarket shopping was related to hyperlipidaemia.
Research limitations/implications
Modernization of food retailing is changing Thai diets and creating diet-related health risks.
Originality/value
The paper addresses a knowledge gap on links between modernizing food retail in Asia and consumption of unhealthy foods, revealing strong linkage in transitional Thailand.
