Assessment of Salt Content and Label Compliance in Processed Packaged Foods of Bangladesh
A countrywide cross-sectional survey was conducted among adults, adolescents, and children to identify commonly consumed processed/ultra-processed foods. Most common items were analyzed using Mohr's titration method to estimate sodium content.

📌 Background & Rationale
Processed and ultra-processed foods (PF/UPFs) are increasingly consumed in Bangladesh, contributing to excessive dietary sodium intake — an important risk factor for hypertension and cardiovascular diseases. However, little is known about the actual sodium levels in these foods or whether label values accurately reflect their true sodium content. Accurate labelling and compliance with WHO sodium benchmarks are essential for enabling consumers to make healthier food choices and for informing sodium reduction strategies.
🔬 Methodology
The researchers conducted a nationwide cross-sectional survey to identify commonly consumed processed and ultra-processed foods in Bangladesh. Household data (974 participants) were used to determine consumption patterns of PF/UPFs. A total of 105 PF/UPF products representing 16 food categories were collected from markets and analyzed in the laboratory using Mohr's titration method to estimate actual sodium content. The sodium levels were compared to WHO sodium benchmarks, and discrepancies between label-reported and laboratory-analyzed sodium content were assessed (allowing ±20% deviation to determine accuracy).
📊 Key Findings
Consumption of PF/UPFs was extremely high (97% reporting intake in the past week). Sodium content varied widely across products, with soups, instant noodles, and chutneys among the highest per 100 g. Many products did not comply with WHO sodium benchmarks. Label accuracy was suboptimal: 40% of products under-reported sodium content, and 9% lacked any sodium labelling at all, undermining consumer information.
📋 Policy Implications
Bangladesh should strengthen nutritional labelling regulations with stricter enforcement of accurate sodium labelling on packaged foods. Adoption of evidence-based national sodium benchmarks for processed and ultra-processed foods is needed, with ongoing compliance monitoring to reduce population sodium intake. Findings can inform policies such as reformulation targets for high-sodium products, public awareness campaigns, and integration of sodium reduction into broader NCD prevention strategies.
