Cranberry Products Associated With Prevention of Urinary Tract Infections

Use of cranberry-containing products appears to be associated with prevention of urinary tract infections in some individuals, according to a study that reviewed the available medical literature and was published by Archives of Internal Medicine,a JAMA Network publication.

For generations, people have consumed cranberry juice, convinced of its power to ward off urinary tract infections, though the exact mechanism of its action has not been well understood.

Urinary tract infections (UTIs) are common bacterial infections and adult women are particularly susceptible. Cranberry-containing products have long been used as a "folk remedy" to prevent the condition, according to the study background.

Cranberry-containing products tend to be more effective in women with recurrent UTIs, female populations, children, cranberry juice drinkers, and people using cranberry-containing products more than twice daily.

Scientific studies done in humans -- have concluded that cranberry juice really is effective for preventing urinary tract infections.

Estimates suggest that urinary tract infections (UTIs) account for about 8 million medical visits each year, at a total cost of more than $1.6 billion. UTIs involve bacterial infections of the urinary tract and can occur anywhere between the urethra, the opening where urine is excreted from the body, and the kidney. Women are frequent victims, with at least 1 in 3 experiencing a UTI. Studies suggest that only half of women with UTIs seek medical care for the mildest symptoms, which include burning and urgency.

UTIs can progress rapidly and, if left untreated with antibiotics, result in severe illness, especially in children, individuals with chronic health problems, and the elderly.

Cranberry juice creates an energy barrier that keeps bacteria away from cells in the urinary tract.

How (and why) to check your medical records

Adopting a Vegetarian Diet

Adopting a vegetarian diet has become a popular choice for individuals looking to improve their health, particularly as heart disease and obesity rates continue to rise in many parts of the world.

Commonly deficient nutrients among vegetarians include protein, iron, vitamin B12, vitamin D, calcium, and zinc. Soy pr...
