The USDA 2010 Dietary Guidelines for American  recommends:

  • Reduce daily sodium intake to less than 2,300 milligrams (mg).
  • Further reduce intake to 1,500 mg among persons who are 51 and older.
  • Reduce intake to 1,500 and those of any age who are African American or have hypertension, diabetes, or chronic kidney disease.
  • The 1,500 mg recommendation applies to about half of the U.S. population, including children, and the majority of adults.” It is estimated that Americans consume about 3400mg per day of sodium.

One in three adults has high blood pressure according to the American Society of Hypertension.

Risk factors for hypertension include:

  • Older age > 35 years
  • Family history
  • Race- African Americans and Hispanic Americans are at higher risk
  • Overweight/obesity
  • Diet high in sodium, too little fruits and vegetables
  • Lack of exercise- recommend at least 30 minutes per day
  • Drinking too much alcohol regularly-more than 2 servings per day

Since the Dietary Guidelines were released, Public Health efforts have focused on reducing the consumption of sodium in the population while many in the food industry have committed to a gradual reduction of sodium in the food supply.  However do consumers care about sodium in their diet?

The 2011 Consumer Sodium Research Report by the International Food Information Council (IFIC) reported that sodium is not a priority for Americans.    Most Americans do not know how much their sodium intake should be or how much sodium they consume. There is also no clear understanding of what constitutes high and low sodium foods.  

As I get older I am astonished at the number of my friends who have high blood pressure or are taking blood pressure lowering medication.  The first thing they tell me is “I never eat salt”.   I want to say that is great but what does the rest of your lifestyle look like? Is salting your food your biggest source of sodium?  Are you exercising routinely?  What about your fruits and vegetables. What is your alcohol intake?  And have you weighed recently?

Experts in the field of chronic disease agree that limiting blood pressure education to sodium restriction does not help the consumer sufficiently to manage their blood pressure. Life style strategies must go beyond limiting sodium intake.  Even the most knowledgeable consumer would have difficulty meeting the 1500 mg/d sodium recommendation without changes in the food supply.  Other strategies for managing high blood pressure include eating more fruits and vegetables, weight management, increasing physical activity and moderating alcohol intake.  While certainly sodium restriction is important; a more holistic approach is needed to help consumers manage their blood pressure.
