Beware of Coffee Side Effect of Speeding up Bone Density Loss

By Kyle J. Norton

Increased life long intake of coffee caffeine >300 mg/day or 2 cups per day may have a potential effect in reduced bone mineral density in menopause women, a Southern America University suggested.

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

It is a widespread degenerative disease of skeletal joints and often associated with senescence in vertebrates due to excessive or abnormal mechanical loading of weight-bearing joints, arising from heavy long-term use or specific injuries(4).

Generally, patients may experience symptoms lower back pain, loss of height over time, a stooped posture,…. and neck pain.

Menopause women with osteoporosis are more likely also experience certain psychosomatic, gastrointestinal and swelling and vasomotor symptoms, especially depressive symptom if compared to women in generally good health.

The single cause of osteoporosis is still detectable. Some researchers suggested that the process of wear and repair, poor nutrients,… and cartilage degeneration are possible causes of the disease.

And, according o Korea Cancer Center Hospital, Seoul,  risk of osteoporosis increased in patients who are diagnosed at the young age puberty, male, decreased lean mass.

Other risk factors may include use of growth hormone replacement, age,,… and family history of osteoporosis.

According to the statistic by the National Osteoporosis Foundation reported that by 2010, about 12 million people over the age of 50 are expected to have osteoporosis and another 40 million to have low bone mass. By 2020, it is expected to increase to 14 million cases of osteoporosis and over 47 million cases of low bone mass [147](5).

This increase in cases could cause the number of hip fractures to double or triple by 2040 [148](5).

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.

In 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.

Milk + coffee= No risk of osteoporosis. Caffeine does not have any effect if  coffee drinkings are > 1 cup per day. 

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”.

Long term caffeinated coffee intake = 2 cups are associated to decrease bone density.

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.

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”.

Caffeine intake of  0-1400 mg/d was not associated with total body or hip bone mineral density.

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.

 Risk of osteoporosis 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”.

Conclusion
Menopause women may have an increased risk of mineral bone density in induction of osteoporosis for caffeine intake  >300 mg/day (approximately 514 g, or 18 oz, brewed coffee).
