Cut Down on the Intake of Acidic Drinks to Keep Your Bone Structure Healthy

Cut Down on the Intake of Acidic Drinks to Keep Your Bone Structure Healthy
The human lifestyle has changed and evolved more rapidly than anyone can imagine. This evolution is not always positive, for some daily habits have negatively affected the health of any individual. From being quite reliant on natural constituents to veering towards chemically designed foods, the long-term impact can be drastic. Upon conducting numerous scientific and academic researches, scientists have identified a relation between osteoporosis and phosphoric acid that is a metallic acid commonly found in acidic drinks.

As students, we formulated a problem linking the role of acidic drinks such as Pepsi and Coca Cola with the appearance of osteoporosis. Our hypothesis was as follows: Phosphoric acid and calcium are usually absorbed by our body in certain amounts, so when the excess Phosphoric acid is removed from our body it can strip away a lot of human calcium reserve with it. We carried out a titration reaction to determine the concentration of phosphoric acid in Pepsi. The results showed that [H3PO4] = 0.0326 mol/L. Phosphoric acid reacts with calcium hydroxide through the following reaction: 3Ca (OH)2 + 2H3PO4→Ca3(PO4)2 + 6H2O. We learned that: When the amount of Pepsi or Cola increases in the human system, the excess Phosphoric acid will strip away a lot of our calcium reserve during its removal from our body. During the given reaction of phosphorous acid found in 330ml of Pepsi or Cola, the titration reaction proved that 0.624g of calcium could be stripped away from our calcium reserve.
As humans, we divert our diets towards products that satisfy our taste buds, without studying their impacts. The result of our experiment, as consumers of acidic drinks, directly linked the long-term effects of what seems to be a harmless drink on our health. Hence, to keep the bones structure intact and healthy, a person should try to cut down on the intake of acidic drinks such as Pepsi and Cola as much as possible.
