Salt Contents in Fermented Dairy Products: A Strategic Blueprint for Healthier Intake.

This study aimed to estimate the quantity and trends of salt intake from industrial fermented dairy products, develop strategies to reduce salt content, and inform policymakers on promoting public health through healthier dairy options. A cross-sectional study was conducted on fermented dairy products. Seventy-nine random samples were selected, and the salt (NaCl %) content was determined by potentiometric titration after sample preparation and homogenization; also samples were analyzed for their moisture (oven drying method). Data analysis involved descriptive statistics and one-sample -test. A comprehensive literature review on salt reduction strategies was also performed proposing a model for an optimized low-salt fermented dairy product. This study found high salt content in many fermented dairy products. Brined cheese had the highest salt level (7.57 g/100 g), while pizza processed cheese had the lowest (1.03 g/100 g). Probiotic yogurts contained less salt (0.29 g/100 g) than regular ones. Other products like doogh (1.04 g/100 g), kefir (0.63 g/100 g), and kashk (2.78 g/100 g) also contributed significantly to salt intake. Most products exceeded recommended salt limits. Consuming just one serving of these products often accounted for a substantial portion of the daily recommended salt intake (WHO: 5 g/day). This research emphasizes the need for reducing salt in fermented dairy products to improve public health. This study highlights the excessive salt content in many fermented dairy products, surpassing recommended daily intake levels. Therefore, to address this public health concern, a multi-faceted approach is necessary. For this purpose, Policymakers should implement stringent monitoring, enforce food labeling, and develop legislation to reduce salt content. Furthermore, the food industry must innovate to reduce salt while maintaining product quality and taste. On the other hand, consumer education and awareness campaigns are crucial for informed choices. Additionally, further research is needed to understand consumer perceptions and the long-term impact of salt-sustainable reduction strategies on dietary habits and public health.
