New Delhi, Nov 12: A new pilot study has found no significant connection between natural dietary intake of D-mannose or urinary acidity and the risk of recurrent urinary tract infections (RUTIs) in postmenopausal women.

Researchers examined 57 women aged 64 to 75 with a history of RUTIs to assess whether dietary habits or urine pH affected infection risk. Participants recorded their food intake and urine pH levels for three days, but results showed no meaningful difference in D-mannose consumption or other nutrients between women with more acidic and less acidic urine.

While foods containing D-mannose were generally more nutrient-dense, the study noted that natural dietary levels were far below those found in supplements marketed for UTI prevention.

Researchers said larger studies are needed to confirm whether D-mannose supplementation or urinary acidity has any true effect on reducing UTI recurrence.
