In Nacional, concerns have been raised about the effectiveness of Nutri-Score in determining if a food product contains excessive salt. Certain products, particularly those that are ultraprocesados, often have high levels of calories, saturated fats, and sugars, as well as salt or chemical additives. Further information on this topic is available from El País, which explores the limitations of Nutri-Score in assessing sodium content.

It is noted that some countries, such as Colombia and Chile, use distinct labeling to warn consumers about excessive sodium in food products, but the situation in Spain is different.
