Cranberry juice


Cranberry juice

Cranberry juice is the juice of the cranberry. Commercially, it is sold in either as a pure juice, which is quite tart, or, more commonly, as cranberry juice "cocktail" or "drink" , in blends with other juices, such as apple or grape, or mixed with water and corn syrup, sugar, or an artificial sweetener (such as aspartame or sucralose). These may also be blended with other juices or flavors. The term, when used on its own, almost always refers to a sweetened drink.

Cranberry juice cocktail is sometimes used as a mixer with alcoholic drinks such as a Cape Codder (1+1/2 ounces of vodka to 4 ounces cranberry juice) or non-alcoholic drinks such as the Bog Grog (2 parts Chelmsford ginger ale [or regular ginger ale] to 3 parts cranberry juice).

Health benefits

Cranberry juice is known to have various health benefits. These include:

Cranberry Juices are usually free from artificial colourings, making them suitable for those who do not consume food dyes.

Cranberry juice and urinary tract infection (UTI)

A known claim is that cranberry juice may help prevent and relieve the symptoms of urinary tract infections by primary and secondary means. The primary means works on the bacteria directly by altering the molecular structure of the fimbriae on the pathogenic strains of the bacteria that cause the infections.[4] The properties of the proanthocyanidins in cranberries prevents the bacteria from adhering to the surface of the bladder and urinary tract.[5] The secondary means works indirectly on the bacteria by changing the intravesical pH (the pH of the bladder's contents) making it more acidic.

However, results from recent randomized controlled trials have been disappointing. A trial of 319 college women with an acute UTI, failed to show that drinking cranberry juice (8 oz of 27% twice daily) would reduce the incidence of a second UTI.[6] Another study performed in The Netherlands randomised 221 women to receive either co-trimoxazole or cranberry capsules. That study found that the antibiotics were superior to cranberry capsules, but were associated with an increase in antibiotic resistance.[7] However, in an accompanying editorial, the dose of cranberries used in the study was criticised for being too low.[8]

Health issues

Although cranberry juice may help prevent growth of bacteria,[9] its pH may be as acidic as 2.3–2.5,[10] which is more acidic than most soft drinks, which could potentially dissolve tooth enamel over time.[citation needed]
