Getting Personal: How Much Sodium Do We Need?
In the field of nutrition, one thing is clear: There is no “one-size-fits-all” approach to a healthy, maintainable eating pattern. Our genetics and environment play significant roles in how our bodies respond to and use certain foods and nutrients. Today, let’s focus on sodium.

It’s also found in many packaged and prepared foods, where it not only adds flavor but also contributes to texture and freshness in its role as a preservative. Sodium can increase the overall safety and quality of our food by lowering water activity, thus prolonging a food product’s shelf life and delaying spoilage. In fact, salt was used as the primary method of preserving meats and various other foods before the invention of industrialized refrigeration. Ninety percent of the sodium we consume is in the form of sodium chloride, but other sodium compounds, such as sodium nitrate and sodium nitrite, are used as antimicrobial agents in some foods. On average, ten percent of our sodium intake comes from adding it during home cooking or at the table, and another ten to fifteen percent occurs naturally in foods, especially meats. More than 70% of our sodium intake comes from packaged foods or restaurant meals. How does sodium affect our health? A small amount of sodium is essential to keep our bodies working as they should. It’s critical for things like muscle function (including the heart) and keeping our nervous system working properly, and it helps to control fluid balance. The Dietary Guidelines for Americans recommend that we consume less than 2,300 milligrams (mg) of sodium each day, which is the amount of sodium in […]
