title: Food consumption patterns of rural older African American, Native American, and white adults in North Carolina.
abstract: This paper describes the major food sources of selected nutrients for an ethnically diverse sample of older adults in rural North Carolina. A representative sample of 130 elders (> 70 years) completed semi-quantitative food frequency questionnaires. Percentages of foods most frequently consumed as the lead source of seven nutrients were calculated overall, by gender and ethnic group. Foods eaten at least one time per week were identified, and percentages of participants consuming that frequency were calculated. Major food sources included: salad oil/cooking oil for calories, total fat and saturated fat; miscellaneous vegetables for dietary fiber and folate; and orange/grapefruit juice for vitamin C. Heterogeneity in food sources was greatest for zinc and least for vitamin C. Variation across gender and ethnic groups was observed only in the degree to which specific food sources contributed to nutrient intake. These data provide greater insight into the dietary patterns of rural elders than examining nutrient intakes.
