Abstract P031: The Impact of Cranberry Juice Beverage Consumption on Macronutrient and Energy Intakes and Body Composition in U.S. Adults
Background: Flavonoids have been shown to function as potent antioxidants both in vitro and in vivo and may reduce the risk of atherosclerosis. Cranberries contain significant amounts of flavonoids and polyphenolic compounds that have been demonstrated to inhibit low-density lipoprotein oxidation. Cranberry beverages (CB) are rich in these antioxidant compounds; however, because of their inherent tartness cranberries are considered unpalatable in their raw state and require the addition of sweeteners to enhance palatability. Because the consumption of some sugar-sweetened beverages has been associated with increased obesity risk, a CHD risk factor, the impact of these antioxidant-containing beverages on diet and obesity is an important area to understand. We sought to examine the association between CB consumption with total sugars, macronutrient, energy intake, and weight status in US adults.
Methods: Data for the US adult population ≥19 years (n=10,891) were drawn from the National Health and Nutrition Examination Survey 2005-2008. The main exposure was the sum of all CB consumption reported over two non-consecutive 24-hour dietary recalls. We examined the difference between CB consumers and non-consumers on a number of dependent variables of interest including marconutrients, total sugars, total energy, sociodemographic characteristics, and anthropometrics, including body mass index (BMI).
Results: CB consumers (n 581) were largely female, white non-Hispanic, and over the age of 50. They had higher daily intakes of carbohydrate and total sugars, but lower total fat intake and no difference in protein intake compared to non-consumers. There was no difference in energy intake or mean BMI between CB consumers and non-consumers; however, a significantly higher proportion of CB consumers had BMIs classified as normal weight compared to CB non-consumers (P < 0.09) and CB consumers were less likely to be classified as obese compared to CB non-consumers (P < 0.05). CB consumers also had lower waist circumference at the first (P < 0.05) and third tertile (P < 0.05) of intake compared to non-consumers. Consumers were significantly more likely to self-report their health status as excellent or very good (P < 0.01)
Conclusions: Cranberry beverage consumption was not associated with higher daily total energy intake or higher BMI in adults. Further, adults who consumed cranberry beverages were more likely to be of normal weight and less likely to be obese. Cranberry beverages provide a rich source of dietary flavonoids and polyphenol, but are not associated with increased energy intake or BMI in adults.
