Bottom Line: Grapefruit consumers were less likely to have usual intakes of vitamin C (males: 0% vs. 47%; females: 0% vs. 43%; P<0.001) and magnesium (P<0.05) below the estimated average requirement (EAR) compared to non-consumers, and they were more likely to meet adequate intake levels for dietary fiber (P<0.05).Potassium and β-carotene intakes were significantly higher among grapefruit consumers (P<0.001).Consumption of grapefruit was associated with higher intakes of vitamin C, magnesium, potassium, dietary fiber, and improved diet quality.

ABSTRACT

Background: Dietary guidance recommends consumption of a nutrient-dense diet containing a variety of fruits. The purpose of this study was to estimate usual nutrient intakes and adequacy of nutrient intakes among adult grapefruit consumers and non-consumers, and to examine associations between grapefruit consumption and select health parameters.

Methods: The analysis was conducted with data collected in the National Health and Nutrition Examination Survey (NHANES) 2003-2008. Respondents reporting consumption of any amount of grapefruit or 100% grapefruit juice at least once during the 2 days of dietary recall were classified as grapefruit consumers.

Results: Among adults aged 19+ years with 2 days of dietary recall (n=12,789), 2.5% of males and 2.7% of females reported consumption of 100% grapefruit juice or fresh, canned, or frozen grapefruit during the recalls. Grapefruit consumers were less likely to have usual intakes of vitamin C (males: 0% vs. 47%; females: 0% vs. 43%; P<0.001) and magnesium (P<0.05) below the estimated average requirement (EAR) compared to non-consumers, and they were more likely to meet adequate intake levels for dietary fiber (P<0.05). Potassium and β-carotene intakes were significantly higher among grapefruit consumers (P<0.001). Diet quality as assessed by the Healthy Eating Index-2005 (HEI-2005) was higher in grapefruit consumers (males: 66.2 [95% CI: 61.0-71.5] vs. 55.4 [95% CI: 54.4-56.4]; females: 71.4 [95% CI: 65.1-77.6] vs. 61.2 [95% CI: 59.8-62.6]). Among women, grapefruit consumption was associated with lower body weight, waist circumference, body mass index (BMI), triglycerides, C-reactive protein (CRP), and higher high-density lipoprotein (HDL) cholesterol (P<0.05), However, risk of being overweight/obese was not associated with grapefruit consumption.

Conclusion: Consumption of grapefruit was associated with higher intakes of vitamin C, magnesium, potassium, dietary fiber, and improved diet quality. Grapefruit may provide a healthful option for adults striving to meet fruit recommendations.

Proportion of male and female grapefruit consumers aged 19+ years by form of grapefruit consumed, NHANES 2003–2008. Grapefruit consumers reported consumption of 100% grapefruit juice or 100% fresh, canned, or frozen grapefruit at least once on the 2 days of dietary recall. Some adults reported consumption of more than one form of grapefruit; the sum of percent consumers by type therefore is greater than 100. All estimates were generated with statistical weights provided by the National Center for Health Statistics (NCHS).

Figure 0001: Proportion of male and female grapefruit consumers aged 19+ years by form of grapefruit consumed, NHANES 2003–2008. Grapefruit consumers reported consumption of 100% grapefruit juice or 100% fresh, canned, or frozen grapefruit at least once on the 2 days of dietary recall. Some adults reported consumption of more than one form of grapefruit; the sum of percent consumers by type therefore is greater than 100. All estimates were generated with statistical weights provided by the National Center for Health Statistics (NCHS).

Mentions: Using the definition of a grapefruit consumer in this analysis, 333 survey respondents aged 19 years and older, representing 2.5% of males and 2.7% of females, were classified as grapefruit consumers (Table 1). Among both males and females, consumers of grapefruit were older and more likely to have an education beyond high school than non-consumers (P<0.005). The percentage of males across race/ethnicity categories differed between consumers and non-consumers of grapefruit (P=0.041). Among males and females, the percentage of adults identified as physically inactive did not differ between consumers and non-consumers of grapefruit. The estimated usual intake of grapefruit was 162 g/day among male consumers of grapefruit and 151 g/day among female consumers. As shown in Fig. 1, male grapefruit consumers were most likely to consume grapefruit in the form of juice, while female consumers of grapefruit were most likely to consume fresh grapefruit.
