Why Is Phosphoric Acid Bad For Your Health?

Why Is Phosphoric Acid Bad For Your Health?

The market for soft drinks, dietary and non-dietetic, was one value of almost US $ 73,000 million in the United States in 2008, according to the "Beverage Digest." Many of these drinks contain phosphoric acid, a substance that has a possible relationship with several health problems. Drinking soft drinks in moderation may be safe, but if you tend to drink a lot of cola, you may want to rethink your options the next time you drink a soda can.

Identification

Phosphoric acid in its pure form is a colorless and odorless crystal extracted from rocks with sulfuric acid or by burning elemental phosphorus and adding water to the byproduct. It is a corrosive acid and can form toxic fumes when it comes in contact with alcohols, ketones and other organic compounds. It is used in fertilizers, feed for livestock, soaps, waxes, dyes, polishing metals and in many other food products. It is added to soft drinks to provide a sharp, sharp spicy flavor and to help curb the growth of fungi and bacteria in sugary formulas.

General side effects

When phosphoric acid dusts are inhaled or come in contact with skin and other body tissues, they can cause dermatitis, pain, tearing, vision blurred, difficulty swallowing or breathing and gastrointestinal problems. Most of these side effects occur in industrial factories where concentrated levels of phosphoric acid are used. The amount of phosphoric acid that is added to soft drinks and other foods in comparison is a very small amount.

Bones

A study published in the "Archives of Pediatric and Adolescent Medicine" in 2000 found that sports teens who drink cola have five times the risk of suffer bone fractures than those who do not consume cola drinks. X-ray tests on 1 672 women in the Framingham Osteoporosis Study between 1996 and 2001 found that the phosphoric acid contained in cola drinks - but not clear carbonated beverages that use citric acid instead - were linked to low bone mineral density in women. However, a clinical study at the Creighton University Osteoporosis Research Center, published in 2001 in the "American Journal of Clinical Nutrition," found no impact of carbonated soft drinks with phosphoric acid on calcium excretion in bones and suggested that Skeletal effects of carbonated beverages are caused by drinking soda instead of milk, which contains calcium.

Teeth

Dental erosion is one of the main concerns about prolonged exposure of teeth to acidic beverages. According to a study published in 2007 in "General Dentistry," the phosphoric acid in soda causes tooth enamel to erode, even at low levels. The only carbonated beverage that did not have this effect was a root beer without phosphoric or citric acid. However, most people do not drink soft drinks for 72 hours, which was the total time that the teeth were submerged in the drinks in the study and the research also did not consider factors such as brushing their teeth after drinking sodas or if Soft drinks were consumed with meals or by themselves.

Kidneys

A team from the National Institutes of Health investigated the eating habits of 465 people with chronic kidney disease and 467 healthy subjects. The results, published in the journal "Epidemiology" in July 2007, found that the consumption of two or more soft drinks a day, either dietetic or regular, was associated with a double risk of developing kidney disease. Clear sodas containing citric acid did not have the same risk. The researchers were not able to identify the exact cause of the results, although they observed that phosphoric acid has been associated with urinary changes that favor kidney stones.
