Cranberry juice for the prevention of recurrent urinary tract infections: A randomized controlled trial in children

Abstract

These data suggest that daily consumption of concentrated cranberry juice can significantly prevent the recurrence of symptomatic UTIs in children.

Adult Cranberry Beverage Consumers Have Healthier Macronutrient Intakes and Measures of Body Composition Compared to Non-Consumers: National Health and Nutrition Examination Survey (NHANES) 2005–2008

“…Numerous clinical studies evaluating the association between cranberry juice consumption with urinary health [20,21,22,23,24,25,26], antioxidant status [27,28], or cardiovascular disease [31,32,33,39], document the health benefits of consuming flavonoids in the form of cranberry products. To our knowledge however, studies evaluating trends in consumption of cranberry beverages, or their association with other markers of health (e.g., anthropometry, dietary status) do not exist.…”

“…Current estimates of flavonoid intake in the US population ranges from 190–210 mg/day [45,46]. Thus, the simple dietary behavior of consuming a single serving of a cranberry beverage daily would almost double the US population intake of flavonoids, an important group of compounds that have been linked to numerous health benefits [20,21,22,27,31,32,33]. …”

“…However, cranberry products contain crucial flavonoids important to health at levels similar or higher than many commonly consumed 100% juices. Although numerous clinical studies evaluating the association between cranberry juice consumption with urinary health [20,21,22,23,24,25,26], antioxidant status [27,28], glycemic response [29,30], or cardiovascular health have been conducted [31,32,33] studies evaluating trends in the consumption of, or association with, other markers of health (e.g., anthropometry, dietary status) do not exist. Determining who cranberry juice consumers are and the extent to which their dietary patterns and health outcomes are similar or dissimilar to non-consumers is crucial for understanding the role that cranberry juice plays in promoting human nutrition and in the development of a healthy lifestyle.…”

Improving public health?: The role of antioxidant-rich fruit and vegetable beverages

“…Both pomegranate and cranberry juices have a tart taste which can be attributed to their high polyphenol content. Cranberry juice contains a complex mixture of compounds including a number of flavonoids, and organic acids, and has been adopted into the common diet as a means of treating urinary tract infections (Ferrara et al, 2009;Guay, 2009;Jepson & Craig, 2007). The TAC and total polyphenols (TP) content of cranberry juice has been quantified in a number of studies (Mullen, Marks, & Crozier, 2007;Seeram et al, 2008;Vinson, Hao, Su, & Zubik, 1998;Piljac-Zegarac et al, 2009) and is reported to be slightly lower (Table 1) than pomegranate (Ryan & Prescott, 2010).…”

Cranberries and lower urinary tract infection prevention

“…No statistical differences were observed for bacteriuria or UTIs (51). Ferrara et al (52) performed a study involving young girls ranging from 3 to 14 years old with recurrent UTIs. They conducted a six-month, randomized trial comparing a 50 ml daily cranberry-lingonberry juice to 100 ml, five days per month of Lactobacillus GG drink containing 4×10 7 colony-forming units or placebo.…”
