Sodium warning: the hidden sodium content of corn on the cob

The irresistible aroma of corn on the cob grilling on a summer evening is enough to make anyone’s mouth water. But if you’re watching your sodium intake, you may wonder, “Does corn on the cob have sodium?” The answer is yes, but understanding the levels and how they can impact your health is crucial.

Sodium Content in Corn on the Cob

The sodium content in corn on the cob varies depending on several factors, including the size of the ear, the growing conditions, and the cooking method.

• Raw Corn on the Cob: One medium ear of raw corn on the cob contains approximately 15 milligrams (mg) of sodium.
• Boiled Corn on the Cob: Boiling corn on the cob can slightly increase the sodium content due to the absorption of water with dissolved minerals. One medium ear of boiled corn on the cob contains about 20 mg of sodium.
• Grilled Corn on the Cob: Grilling corn on the cob without added salt or seasoning typically does not significantly increase the sodium content. However, if you add salt or butter during grilling, the sodium content can rise considerably.

Impact of Sodium on Health

Sodium is an essential mineral that plays a vital role in maintaining fluid balance and regulating blood pressure. However, excessive sodium intake can contribute to high blood pressure, heart disease, and stroke.

The American Heart Association (AHA) recommends limiting daily sodium intake to less than 2,300 mg for adults. For individuals with high blood pressure or at risk of heart disease, the recommended daily sodium intake is even lower, at 1,500 mg.

• Select Smaller Ears: Smaller ears of corn on the cob generally have lower sodium content than larger ears.
• Avoid Canned Corn on the Cob: Canned corn on the cob is often packed in brine, which adds significant amounts of sodium.
• Choose Fresh or Frozen Corn on the Cob: Fresh or frozen corn on the cob is a better low-sodium option than canned varieties.
