Objective: The sodium intake of participants of the Healthy Aging in Neighborhoods of Diversity across the Life Span study who were in three of the special population groups identified by the Dietary Guidelines for Americans, 2010 (those with hypertension, African Americans, and those ≥51years) was analyzed to determine if they met sodium recommendations.
Methods: The sample included 2152 African American and White subjects, aged 30-64years. Major dietary sources of sodium for each group were determined from two 24-hour dietary recalls, and dietary intakes were compared with sodium recommendations. Dietary potassium was also evaluated.
Results: The intakes of the groups studied exceeded 1500mg of sodium while their potassium intakes were lower than the Adequate Intake of 4700mg. The major contributors of sodium included "cold cuts, sausage, and franks," "protein foods," and yeast breads.
Conclusions: Excessive sodium intake characterized the diet of an urban, socioeconomically diverse population who are hypertensive or at risk for having hypertension. These findings have implications for health professionals and the food industry.
