Do Thai Customers Pay for Different Front-of-Package Nutrition Labels?

Thai consumers have recently become more aware and selective in their food choices.  On the regulator’s side, the Food and Drug Administration (FDA) in Thailand now requires the monochrome GDA label in order to support Thai consumers’ demand for such information. A recent research article from Thitiporn Thanavutwatthana and Dr.Yingyot Chiaravutthi from the Mahidol University International College (MUIC) explores how Thai consumers react to different types of front-of-package (FOP) nutrition labels, including the monochrome GDA label, the color-coded GDA label, and the traffic light label.  The experimental auction was employed as a tool to extract consumers’ willingness to pay.  Seventy two representative consumers participated in the experiment.  The food products used in this research were seaweed and almonds, which are popular snacks amongst Thai consumers.   

 


The results show that Thai consumers have a different willingness to pay for food products that have different nutritional values.  Without the FOP label, grilled seaweed receive a lower willingness to pay than fried seaweed; whilst unsalted almonds have a higher willingness to pay when compared to salted almonds.  This result could arise from consumers’ preferences of one certain taste over another.  In terms of actual market prices, both types of seaweed have the same market prices, since both come under the same producer; which is also true in the case of almonds.  Another important finding is that any type of FOP nutrition label adds some value to the food products, regardless of their nutritional values.

 

Although consumers are willing to pay higher prices for products with the monochrome GDA label, this type of label also raises the willingness to pay for unhealthy choices as well.  The traffic light label, on the other hand, seems to be an effective tool in influencing consumers’ decision making.  Thai consumers prefer fried seaweed over grilled seaweed as presented in Table 10; but with the traffic light label, grilled seaweed now has a higher price premium.  Note that fried seaweed has red lights on both the fat and the saturated fat categories, whilst grilled seaweed has green lights on both categories.  The traffic light is obvious and easily understood, and it does sway consumers’ behavior.  As for almonds, consumers give higher prices to unsalted almonds over salted almonds with the plain label and the traffic light label.  Note that the amount of sodium in salted almonds used in the experiment has not yet reached the red light level.  As such, consumers were making comparisons between the green and the amber lights.

 The experiments were conducted on two groups of participants, the uninformed and informed ones.  The informed group was given additional information about the meanings of different FOP labels.  Informed consumers react positively to the monochrome GDA label, since they are willing to pay higher prices for all food products.  The healthier foods, in particular, receive much higher premiums relative to the less healthy choices.  Nevertheless, the traffic light label is highly recommended, as it could still influence consumers’ decisions.  For uninformed consumers, grilled seaweed and fried seaweed receive the same willingness to pay, whilst salted almonds result in a higher willingness to pay.  But when information is provided, grilled seaweed and unsalted almonds now receive higher values.    

 Although more research on the effectiveness of the nutrition label policy ought to be conducted on a larger scale, in order to cover more representative samples of Thai consumers; the results from this experiment should serve as an early warning signal in terms of the current policy.  From a producers’ perspective, implementation of the monochrome GDA label required by the Thai FDA may not severely affect their sales, even in the case of unhealthy products.  As for the policy makers, their ultimate objective may not be reached through their monochrome GDA label requirement, since consumers’ overall reactions towards such labels remain positive.  Showing nutritional facts on the front of the package may mislead some consumers into thinking that certain foods are not that unhealthy, and encourage those consumers to actually purchase them.  This is especially true when the nutrition label is not presented in a simple and easily understandable way.  The adoption of the traffic light label should be considered along with an aggressive policy on raising the public awareness.  It would be socially desirable if the food label policy could help consumers to make a healthier choice.
