Caffeine & Osteoporosis

Caffeine In Regards to Osteoporosis

 

As little as three cups of coffee a day can be harmful to middle aged women at

risk of osteoporosis, a new study says.

Investigators found women who consumed the most caffeine had

significantly lower bone mineral density after three years compared with women

who consumed the least.

 

The findings bolster research linking the consumption of caffeine, found in

coffee, chocolate, sodapop and other drinks, to the bone thinning disease

osteoporosis.

This study was led by Dr. Prema Rapuri from Creighton University in Omaha,

Nebraska.

 

According to results published in the November issue of American Journal of

Clinical Nutrient, women who consumed more than 300 milligrams of caffeine a

day, the equivalent of about three cups of brewed coffee, were more likely to

lose bone in their

spine.

 

Caffeine in coffee and soft drinks causes the body to excrete calcium and tends

to stress the adrenal glands, leading in some cases to general exhaustion,

including exhaustion of the heart muscle.

Each 10 mg. of caffeine consumed causes a 1 mg calcium *loss* in the

bones. This affects children as well as adults. One study showed that calcium

loss actually doubled in 133'of 135

subjects who used caffeine.

 

Additionally " phosphoric acid " in soft drinks can damage 'developing'

bones by taking calcium from them. (American Journal of Epidemiology

 

 

Chlorogenic acid in coffee causes some of the most **intense** food

allergies encountered in medical practice. (JAMA) While all methylxanthines

(class of toxic alkaloid chemicals) are harmful to the thyroid, coffee is high

in 'theophylline', which is the most 'damaging' to the thyroid. (Endocrinology

 

Bone tissue has long been recognized as a key accumulation site for

some toxic substances – " bones also serve a detoxicating function,

elements such as lead, radium, fluorine and arsenic being removed from

circulation and deposited into bones and teeth " (The Physiological Basis of

Medical Practice, 1961).

 

That is, fluoride accumulates in skeletal tissue, concentrating in the surface

layers of the lacunae and canaliculae -- thus helping to clarify the

pathogenesis of the osseous lesions seen in skeletal fluorosis (Smith,

1985a).Bone samples from cadavers show that fluoride content of trabecular bone

correlates with that of the drinking water --

with histomorphic bone changes becoming markedly increased when water fluoride

content exceeds 1.5-ppm (Alrnala, et al. 1985).

 

Epidemiology --Fluoride is a cumulative toxin, adversely affecting the

homeostasis of bone mineral metabolism. Total ingested fluoride is the most

important factor determining the clinical course of osteo-fluorosis,

which is on the increase world-wide (Krishnamachari, 1986).

 

A level of 4-10 ppm in drinking water causes progressive ankylosis of

various joints and crippling deformities irrespective of other variables –

as evidenced by skeletal radiology and scintigraphy, cross-correlated

with urinary and serum fluoride levels (Gupta, et al. 1993).

 

That fluoride potentiates neuro- toxicity of aluminum hasbeensubstantiated (van

der Voet, et.al. 1999) -- consisting of interference with neuronal cytoskeleton

metabolism.

 

Aluminum accumulations have been found in nuclei of the

paired-helical filament (PHF) containing neurons in the brains of

both AD patients and elderly normal controls (Shore and Wyatt, 1983)

but as no elevations of aluminum were found in serum or

cerebrospinalfluid of AD patients, aluminum alone is not the cause – rather,

aluminum in PHF bearing neurons is simply a " marker " .
