How about cola carbonated beverages?

Two days ago a dentist gave her patient, a young girl lidocaine adrenaline injections and after about 10 minutes, patient didn't feel numbness. Then she asked her whether she likes to drink cola or not. I was surprised when she said she drinks cola 6 cans daily. The dentist was surprised to "What? 6 cans? That's too much for one day." Then I asked her why cola can affect sedation, she said it is because of high level of caffeine in it. I was really curious so I tried to find information about carbonated beverages, especially cola........



As I know every carbonated beverages contains of high sugar level, so it will affect sugar level if consumed in long periods.In 2004, an eight-year study of 50,000 nurses showed a correlation that suggests drinking one or more sugar-sweetened beverages (such as soft drinks and fruit punches) per day increases one's risk of developing diabetes by 80%. Most soft drinks contain high concentration of simple carbohydrates, glucosefructose, sucrose and other simple sugars. Oral bacteria ferment carbohydrates and produce acid, which dissolves tooth enamel during the dental decay process; thus, sweetened beverages are likely to increase risk of dental caries.

How about cola carbonated beverages? Being carbonated, colas are acidic carbonic acid is formed when carbon dioxide dissolves in water, and so can react violently with basic chemicals, such as baking soda. Many colas also contain phosphoric acid and/or citric acid, which further increases the acidity. So it's the same, carbonated beverages in any form is not good for our body. I know it quenches thirst very fast, but it's not good to take too much.

Cola carbonated beverages contains on high level of caffeine. What is caffeine? Caffeine is an alkaloid compound that acts as a psychoactive stimulant and diuretic in humans. The word comes from the French term for coffee, café. Caffeine is also called guaranine when found in guarana, mateine when found in mate, and theine when found in tea; all these names are considered chemical synonyms for the same chemical compound.

Don't you think cola is refreshing because contains of caffeine? In human, caffeine is a central nervous system stimulant, having the effect of temporarily warding off drowsiness and restoring alertness. Hmmm, now I understand why those injections didn't have effect to patient. Because low concentration of adrenaline on one ampoule of lignocaine adrenaline 0.8% cannot defeat high concentration of caffeine level in her body. Remember that caffeine is central nervous system stimulant. That's why patient still feel painful after 10 minutes injections given.

So what is the normal caffeine level that should be present in our body? Caffeine is usually thought to be safe in moderate amounts. Experts consider 200–300 mg of caffeine a day to be a moderate amount for adults. But consuming as little as 100 mg of caffeine a day can lead a person to become "dependent" on caffeine. How much that patient drinks daily? She said she drinks Pepsi Cola 6 cans daily. Pepsi Cola contains of 38 mg per 12 ounces (1 can) equivalent to 228 mg daily. Actually it's ok for body, but remember that patient is young girl. So it's too much for her.

Finally I just want to say, combination of carbonated beverages and caffeine is bad for our body. So try to drink cola carbonated beverages rarely. Only if you don't have other alternative drinks.
