Food Sources of Sodium

Sodium is present in most whole plant food we eat although vegetables, poultry, fruits, contain smaller amounts. Fresh plant-based foods usually contain a lower amount of sodium when compared to animal foods like dairy, dairy products, and meats.

Processed, canned, and packaged foods have the highest concentration of sodium. This includes chips, fast foods, frozen foods, and all kinds of processed and paced foods where salt is added during the process to improve the taste.

Another common source of sodium is table salt. Adding table salt when preparing your food increases the amount of sodium you take in. if you are placed on a low-sodium diet, you have to limit your intake of all these.

In some health conditions like kidney problems, heart disease, high blood pressure, and other chronic disease of the body, sodium level should be restricted.

In this diet, your intake of sodium should be less than 2 to 3 grams daily (2,000 to 3,000 mg). However, there are variations of this diet. A teaspoon of table salt contains 2,300 mg of sodium.

So, when on a low-sodium diet, you have to eliminate table salt from your diet. You also have to avoid certain foods so that you can keep your sodium level under a recommended level.
