Cola and osteoporosis

Cola and osteoporosis

This is important clinical research. With focus on administration of Vitamin

D-3, Vitamin K-2, Strontium, Calcium and Boron, we often pay too little

attention to the dietary factors that may worsen osteoporosis. This is one very

easy step, one very important step in the treatment of osteoporosis.



This is an exerpt from the National Library of Medicine abstract, for your

reading pleasure.

are associated with low bone mineral density in older women: The Framingham

Soft drink consumption may have adverse effects on bone mineral density (BMD),

but studies have shown mixed results. In addition to displacing healthier

beverages, colas contain caffeine and phosphoric acid (H3PO4), which may

adversely affect bone.

DESIGN: BMD was measured at the spine and 3 hip sites in 1413 women and 1125 men

in the Framingham Osteoporosis Study by using dual-energy X-ray absorptiometry.

Dietary intake was assessed by food-frequency questionnaire. We regressed each

BMD measure on the frequency of soft drink consumption for men and women after

adjustment for body mass index, height, age, energy intake, physical activity

score, smoking, alcohol use, total calcium intake, total vitamin D intake,

caffeine from noncola sources, season of measurement, and, for women, menopausal

status and estrogen use.

RESULTS: Cola intake was associated with significantly lower (P < 0.001-0.05)

BMD at each hip site, but not the spine, in women but not in men. The mean BMD

of those with daily cola intake was 3.7% lower at the femoral neck and 5.4%

lower at Ward's area than of those who consumed <1 serving cola/mo. Similar

results were seen for diet cola and, although weaker, for decaffeinated cola. No

significant relations between noncola carbonated beverage consumption and BMD

were observed. Total phosphorus intake was not significantly higher in daily

cola consumers than in nonconsumers; however, the calcium-to-phosphorus ratios

were lower.

CONCLUSIONS: Intake of cola, but not of other carbonated soft drinks, is

associated with low BMD in women. Additional research is needed to confirm these

findings.
