Foods High in Sodium: An Overview
Introduction to Sodium in Foods
Sodium is an essential mineral that the human body needs to function properly. However, excessive sodium intake is linked to various health issues, including hypertension, cardiovascular diseases, and renal problems3 6. Understanding which foods are high in sodium can help individuals make healthier dietary choices and reduce their risk of sodium-related health problems.
Common High-Sodium Foods
Processed and Packaged Foods
Processed and packaged foods are significant sources of sodium. Items such as sausages, hamburgers, ham, bread, tomato sauce, ketchup, mustard, mayonnaise, and mashed potatoes often contain high levels of sodium, sometimes exceeding 460 mg per 100 grams3. In some cases, sodium content can be as high as 2851 mg per 100 grams, particularly in certain mashed potato products3.
Street and Fast Foods
Street food and fast food are also major contributors to high sodium intake. In Malaysia, for example, street foods like fried noodles and noodle soup can contain over 2000 mg of sodium per serving9. Similarly, in Argentina, street foods, fast foods, and artisanal foods have been found to contain high sodium levels, with averages ranging from 520 to 599 mg per 100 grams5.
Commonly Consumed Foods
In many countries, everyday foods such as bread, fried vegetables, and soy sauce are significant sources of sodium. In Malaysia, fried vegetables and bread are among the most commonly consumed high-sodium foods, with soy sauce contributing significantly to daily sodium intake2. In China, sauces, dressings, and dips have the highest average sodium content, followed by bean products and fish, meat, and egg products7.
Sodium Content in Different Food Categories
Sauces and Condiments
Sauces, dressings, and dips are among the highest in sodium content, with averages reaching up to 6888.6 mg per 100 grams7. Soy sauce, in particular, is a major contributor to sodium intake in many Asian countries6 7.
Processed Meats
Processed meats such as sausages, hamburgers, and ham are also high in sodium. These foods often contain added salts and preservatives, which significantly increase their sodium content3 8.
Baked Goods
Baked goods, including bread and snacks, are another major source of dietary sodium. In the UK and US, cereals and baked goods are the single largest contributors to sodium intake6. In Spain, processed meats and snacks also have high sodium content8.
Public Health Implications
Health Risks
High sodium intake is associated with increased risks of hypertension, cardiovascular diseases, and stroke6 8. Public health strategies to reduce sodium intake include monitoring salt content in foods, improving nutritional labeling, and reformulating products to contain less sodium5 8.
Policy Recommendations
Efforts to reduce sodium intake should focus on the main sources of dietary sodium in different populations. For instance, in Japan and China, reducing the use of salt and soy sauce in home cooking could be effective6. In Western countries, reducing sodium in processed and packaged foods could have a significant impact3 8.
Conclusion
Understanding the sodium content in various foods is crucial for making healthier dietary choices. Processed and packaged foods, street and fast foods, and common everyday items like bread and soy sauce are significant sources of sodium. Public health strategies should focus on reducing sodium content in these foods to mitigate the associated health risks.

SODIUM CONTENT OF FOODS
*Eating more than the serving size for a moderate or low-sodium food will make it a high-sodium food. Foods made with high-sodium foods will also be high in sodium. *Unless otherwise noted, all foods are cooked; meat is roasted, fish is cooked with dry heat, vegetables are cooked from fresh, and fruit is raw. *This is a guide. Actual values may vary depending on product and/or processing. Canned and processed foods may have a higher sodium content. * Values are rounded to the nearest 5 mg increment and may be averaged with similar foods in group.
