Characterization of the Types of Sweeteners Consumed in Honduras.

Sweeteners are found in all types of foods, and their high consumption is associated with chronic degenerative diseases, such as diabetes and obesity, among others. A characterization was carried out of food products with sweeteners from the three biggest supermarkets at a national level; they were identified by the list of ingredients and classified according to caloric or non-caloric intake, and pursuant to their country of origin. A statistical interpretation of results was made using descriptive measures such as the number of times the sweeteners were found in the formulation of the products and how many of them were found in a product at the same time. In total, 341 products were evaluated and classified according to the processed food categories of the Pan American Health Organization (PAHO) nutrient profile. The category of beverages had the highest quantity of products with sweeteners, and their consumption by the inhabitants represents a high exposure. Overall, 60.1% of the products evaluated were of US origin; these US exports have a significant impact on the Honduran market. A high-fructose corn syrup caloric sweetener was the one most frequently found in these products; at least 51% are combined with additional sweeteners to increase the sweetening effect.

Impact of the North American Free Trade Agreement on high-fructose corn syrup supply in Canada: a natural experiment using synthetic control methods.

BACKGROUND: Critics of free trade agreements have argued that they threaten public health, as they eliminate barriers to trade in potentially harmful products, such as sugar. Here we analyze the North American Free Trade Agreement (NAFTA), testing the hypothesis that lowering tariffs on food and beverage syrups that contain high-fructose corn syrup (HFCS) increased its use in foods consumed in Canada. METHODS: We used supply data from the Food and Agriculture Organization of the United Nations to assess changes in supply of caloric sweeteners including HFCS after NAFTA. We estimate the impact of NAFTA on supply of HFCS in Canada using an innovative, quasi-experimental methodology - synthetic control methods - that creates a control group with which to compare Canada's outcomes. Additional robustness tests were performed for sample, control groups and model specification. RESULTS: Tariff reductions in NAFTA coincided with a 41.6 (95% confidence interval 25.1 to 58.2) kilocalorie per capita daily increase in the supply of caloric sweeteners including HFCS. This change was not observed in the control groups, including Australia and the United Kingdom, as well as a composite control of 16 countries. Results were robust to placebo tests and additional sensitivity analyses. INTERPRETATION: NAFTA was strongly associated with a marked rise in HFCS supply and likely consumption in Canada. Our study provides evidence that even a seemingly modest change to product tariffs in free trade agreements can substantially alter population-wide dietary behaviour and exposure to risk factors.
