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.

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
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
