During this lesson I talked to the students about what caffeine is: a stimulant drug that is in many foods and drinks consumed in the US. I explained that stimulants are drugs that speed everything up; people often use stimulants because they speed up your heart rate, give a sense of increased energy and added focus and can keep a person awake for long periods of time. People that abuse stimulants may have heart problems, they may have trouble concentrating and they may be unable to sleep. In addition to caffeine, other stimulant drugs include tobacco (must be 21+ to use), prescription drugs like Adderall and Ritalin (used for conditions like ADD and narcolepsy), and illegal drugs like methamphetamine, cocaine and ecstasy. Although these drugs differ in strength and effects, if abused they can all yield similar problems.
During class we screened a few minutes of a video about caffeine abuse. The video covers the story of a teenage athlete that passed out on the field after overusing caffeine. While watching the video, I also explained the importance of reading and understanding nutrition labels on food and drinks, and I also shared some stories of caffeine abuse from the schools that I have been teaching in over the past few years.
After the video, I told the kids the average amount of caffeine in the most common caffeinated drinks, and I answered questions about any products the kids may have encountered. Here are the caffeine levels in the most popular caffeinated food and drinks:
- soda/colas: 30-50 mg per 12 oz can
- Monster/Rockstar: 160 mg per can
- Red Bull (small can): 90 mg per can
- 5 hr Energy: 200-250 per bottle
- Starbucks: 225-430 mg depending on size
- Keurig K – cup: 75-150
- Hershey’s Kiss – 1 mg
After going over these amounts, I gave the kids a rule for how much caffeine a growing kid (middle school, high school, maybe halfway into college) should not exceed:
No More Than 1mg Per Pound Per Day (1mg/lb/day)
This rule is based on a recommendation from the Canadian Government regarding kids and caffeine use. For one reason or another, the US has never made a ruling for how much caffeine a person of any age should have.
I emphasized to the kids that this rule is for them to use as they grow. Adults can have higher amounts of caffeine without negative results, and caffeine does not have the same risks for adults associated with the more powerful stimulants or drugs in other categories (so there’s no need for your child to slap the coffee or diet coke out of your hand in terror tomorrow morning).
