Abstract
Background
In response to the global target for reduction in salt intake, several countries have implemented population sodium reduction strategies. These strategies include identification of major sources of sodium in the diet and reformulation of a set number of products available on the market. This study aimed to identify processed foods that can be targeted for reformulation and whose sodium content can be monitored over time in order to reduce sodium intake in the Philippines. The objectives were to: 1) Estimate per capita sodium intake from minimally processed and processed food groups by income quintile and urban/rural location; 2) Identify foods that contribute to the variance in per capita sodium intake that can be used as indicators for monitoring the sodium content of Philippine processed foods. One-day household food weighing data covering 4880 households from the 2008 National Nutrition Survey was used. Per capita sodium consumption from processed and minimally processed food categories and percentiles of sodium intake from these categories by income quintile and urban/rural location were obtained. The percentage contribution of different food categories to mean per capita sodium intake was calculated. Specific foods that contributed to the variance in sodium intake among Filipinos were identified.
Results
Foods which significantly accounted for 99.4% of the variance in sodium intake were 13 types of processed foods and 2 types of minimally processed foods. The category Processed Soup, Sauces, and Flavor Enhancers contributed the greatest proportion to per capita sodium intake. Specific processed foods that contributed to the variance in per capita sodium intake were instant noodles, traditional fermented condiments and sauces, dried and processed meat, fish, and poultry products, salted eggs, white bread and pan de sal (a traditional Filipino bread), wheat and egg noodles, crispy cereal chips and extruded snacks, butter and margarine, cheese, and chocolate-based beverages.
Conclusion
Identifying processed foods that significantly contribute to sodium intake, followed by reformulating and monitoring the sodium content of these foods over time should be considered as one strategy to reduce sodium intake in the Philippines.
