According to a conversation I had recently, it is not common knowledge that most soft drinks (soda, pop…whatever the kids are calling them these days) contain caffeine, not just Coca-cola. So here are a few facts about the drug:
“Caffeine is consumed as a natural part of coffee, tea, chocolate and certain flavours (e.g. those derived from kola and guarana), and may be added to carbonated soft drinks. When used in food, caffeine is regulated as a food additive under the Food and Drug Regulations, which requires a thorough safety assessment by Health Canada scientists before any new uses are permitted.
Caffeine exhibits a number of biological effects resulting from its diuretic and stimulant properties. Research has shown that some sensitive individuals experience side effects such as insomnia, headaches, irritability and nervousness. As with any substance, there can be numerous other contributing factors, but Canada’s Guidelines to Healthy Eating advises consumers that limiting caffeine is a wise precaution.”
An 8 oz. cup of coffee contains about 135 milligrams of caffeine, and 8 oz. of the average black tea contains 43 mg. Of the most common soft drinks, per 12 oz. serving, Mountain Dew takes the cake with 54 mg. of caffeine, Dr. Pepper rings in at 41, Coke at 35, Pepsi at 38, followed by Barq’s Root Beer at 23.
Red Bull and Guru are on the conservative side of things in terms of energy drinks, coming in at 80 and 125 mg respectively.
7-up, Sprite and Orange Crush are caffeine free!
According to Health Canada, adults shouldn’t consume more than 400 mg per day, or about three 237-ml (eight- ounce) cups of regular coffee. Pregnant women should keep it to two cups.
The maximum daily caffeine intake for children should be:
4 – 6 years 45 mg/day
7 – 9 years 62.5 mg/day
10 – 12 years 85 mg/day
