Intake Coffee Caffeine >300 mg/day In Increased Risk of Osteoporosis

By Kyle J. Norton

Increased life long intake of coffee caffeine may have a potential effect in reduced bone mineral density in menopause women, a Southern America University opinionated.

Coffee, a popular and social beverage all over the world, particular in the West, is a drink made from roast bean from the Coffea plant, native to tropical Africa and Madagascar.

Osteoporosis is a condition of thinning of bone and bone tissues as a result of the loss of bone density over a prolong period of time.

A study to investigate whether increased coffee intake expressed a linear effect in risk of increased ageing bone density of  980 postmenopausal women aged 50 to 98 years (mean age, 72.7 years) in community-based population of older women, Rancho Bernardo, Calif.participated between 1988 and 1991, researchers showed that women drinking coffee without adding milk have a strong effect in risk of osteoporosis, but for women drinking at least one cup of milk a day, coffee caffeine intake do not impede bone density.

Dr. Barrett-Connor E, the lead author said, “Lifetime caffeinated coffee intake equivalent to two cups per day is associated with decreased bone density in older women who do not drink milk on a daily basis”.
 

Other, in the measured the bone density of both hips and the total body in 138 healthy, postmenopausal women aged 55-70 y who  never used hormone replacement therapy, returned reports including current and long-time caffeinated beverage, suggested that with the same anthropometric and nutrient intakes, caffeine intake was not associated to osteoporosis regardless numbers of cups drinking per day.

Interestingly, based on brewed beverages chemical analysis, most computer models have over estimated the caffeine intake of prospects by nearly two-thirds.

Base on the finding evidences, Dr. Lloyd T. the lead author said, ” the habitual dietary caffeine intake of this cohort of 138 postmenopausal women ranged from 0-1400 mg/d and was not associated with total body or hip bone mineral density measurements”.

Furthermore, according to the Creighton University, School of Medicine study of cross-sectional measurements of BMD in 489 elderly women (aged 65-77 y) and from longitudinal measurements made in 96 of these women who were treated with coffee in compared to a placebo for 3 y. showed a nonlinear result of osteoporosis risk increased in women drinking over < or =300 mg/d in compared to low and moderated groups.

The study also specified that, all 3 groups showed some forms of bone density loss, and higher bone density loss is correlated to cups of coffee drinking per day.

Particularly, Dr, Rapuri PB, said, “Intakes of caffeine in amounts >300 mg/d ( approximately 514 g, or 18 oz, brewed coffee) accelerate bone loss at the spine in elderly postmenopausal women”.

Taking altogether,  menopause women may have an increased risk of mineral bone density in induction of osteoporosis for drinking  >300 mg/day. Due to conflict results from the above studies, further confirmation with large size and multi centers studies are necessary.
