For people who drink colas on a regular basis, a new study reveals this habit may be linked to a decrease in bone density. The results are based upon soda consumption, particularly colas, of more than 4 to 5 sodas per week.
While researchers clearly found a link between cola consumption and bone density loss, the method of loss and the reason the bone density is lowered has yet to be determined. There are three possibilities regarding the bone density loss.
The cola consumption may take the place of the consumption of other forms of liquid that my be higher in calcium and Vitamin D, including milk and fortified juices.
A second theory states that the caffeine levels in cola may be to blame for the reduction in bone density.
The third, and most followed theory is associated with the inclusion of phosphoric acid in colas. Phosphoric acid, when consumed, requires calcium to neutralize the acid. When not enough calcium is readily available, the body will turn to the bones for the calcium needed.
A reduction in bone calcium has been linked to osteoporosis, especially in post menopausal women. Osteoporosis is marked by a thinning of the bones, due to the lack of calcium and calcium absorption and can cause serious injury if the condition remains unchecked and untreated.
In the study of more than 2,000 patients averaging 60 years of age, women were found to have lower bone density at three hip sites when cola was consumed on a regular basis. As few as five carbonated drinks (four being cola) per week was needed to see a marked change in bone density.
The study also revealed less of a change when decaffeinated colas were consumed, but showed no difference between the sugared or diet colas. Men showed no reduction in bone density.
While the connection between the lowering bone density and cola consumption was clear, researchers are not claiming that cola be given up all together. Moderate intakes of cola, one to two per week, are considered within normal limits.
Researchers also added that the proper amounts of calcium and Vitamin D are needed from both food and supplement sources. A minimum of 1,000 to 1,200 mg of calcium per day is suggested with varying amounts based upon age.
