The phosphoric acid in soda lowers bone density

Biological effects on bone calcium and kidney health

Phosphoric acid, used in many soft drinks (primarily cola), has been linked to lower bone density in epidemiological studies. For example, a study[2] using dual-energy X-ray absorptiometry rather than a questionnaire about breakage, provides reasonable evidence to support the theory that drinking cola results in lower bone density. This study was published in the American Journal of Clinical Nutrition. A total of 1672 women and 1148 men were studied between 1996 and 2001. Dietary information was collected using a food frequency questionnaire that had specific questions about the number of servings of cola and other carbonated beverages and that also made a differentiation between regular, caffeine-free, and diet drinks. The paper cites significant statistical evidence to show that women who consume cola daily have lower bone density. Total phosphorus intake was not significantly higher in daily cola consumers than in nonconsumers; however, the calcium-to-phosphorus ratios were lower. The study also suggests that further research is needed to confirm the findings.

On the other hand, a study funded by Pepsi suggests that low intake of phosphorus leads to lower bone density. The study does not examine the effect of phosphoric acid, which binds with magnesium and calcium in the digestive tract to form salts that are not absorbed, but, rather, it studies general phosphorus intake.[3]

I don't want you to depend on milk to get your calcium. This is because milk has a poor calcium to magnesium ratio. Your body needs a certain amount of magnesium in order to get the calcium into your bones -- without magnesium, calcium can't build strong bones.

Cola consumption has also been linked to chronic kidney disease and kidney stones through medical research.[6] This study differentiated between the effects of cola (generally contains phosphoric acid), non-cola carbonated beverages (substitute citric acid) and coffee (control for caffeine), and found that drinking 2 or more colas per day more than doubled the incidence of kidney disease.

Rust removal

Phosphoric acid may be used by direct application to rusted iron, steel tools, or surfaces to convert iron(III) oxide (rust) to a water-soluble phosphate compound. It is usually available as a greenish liquid, suitable for dipping (acid bath), but is more generally used as a component in a gel, commonly called naval jelly. As a thick gel, it may be applied to sloping, vertical, or even overhead surfaces. Care must be taken to avoid acid burns of the skin and especially the eyes, but the residue is easily diluted with water. When sufficiently diluted, it can even be nutritious to plant life, containing the essential nutrients phosphorus and iron. It is sometimes sold under other names, such as "rust remover" or "rust killer." It should not be directly introduced into surface water such as creeks or into drains, however. After treatment, the reddish-brown iron oxide will be converted to a black iron phosphate compound coating that may be scrubbed off. Multiple applications of phosphoric acid may be required to remove all rust. The resultant black compound can provide further corrosion resistance (such protection is somewhat provided by the superficially similar Parkerizing and blued electrochemical conversion coating processes.) After application and removal of rust using phosphoric acid compounds, the metal should be oiled (if to be used bare, as in a tool) or appropriately painted, by using a multiple coat process of primer, intermediate, and finish coats.




You don't have to be very smart to realize that you shouldn't be drinking some artifical bull**** full of strange things that takes rust off of metal.

Fear monger! It's also been shown to be negated with a proper diet.

If phosphate intake is too high it can increase parathyroid hormone.

It is also interesting that parathyroid hormone has effects on adipose cells.

However, these days I think insulin levels have legitimate effects on Ca++ levels. This makes the tie in between parathyroid and adipose function more complicated than just taking supplemental Calcium (or making sure you don't overdo the phosphate) to correct the problem.

I love how your name is phosphate bond lol

Interestingly just today I had an orthopedic surgeon lecture me on how children are at a significant risk for loss of their maximal skeletal development due to the high content of phosphoric acid in sodas that this age-group often drinks excessively.

As stated, with a proper diet, this 'risk' is completely insignificant.

Did you realize that 100 grams of potato has over 5 times more phosphorous than 100 grams of cola?

Better not eat potatoes, they'll ruin your bones!
(Actually they will ruin your bones if you have kidney failure and don't watch your phosphorous intake, but your fine if your kidneys are working).

100 grams of cola is what 100cc's? That is like 3.2 ounces of soda?

About that yes. I realize that most colas are larger than that and therefore people get a lot more phosphorous. People also tend to eat more than 100 grams of potato in one sitting as well (take a large fries for example).
My point is that many things we eat have a ton of phosphorous in them, not just soda.

If you have working kidneys, your serum phosphate levels will remain between 0.8 - 1.5 mmol/L and should not be a significant problem to your bone health.

Yeah normally parathyroid decreases phosphate in the blood by using the kidney to increase excetion. At the same time Ca++ is reabsorbed by the kidney balancing things out.

The only problem with having excess dietary phosphorous is that magnesium and possibly potassium are used to excrete the excess phosphate at the same time.

Anyway, This is one reason why lifting weight helps. Muscle that is training increases uptake of phosphorus.
