As a vending machine operator, you’re most likely vending enough caffeine to keep an army of grown adults awake for days. You’ve also most likely have thought about how that caffeine is affecting your customers. According to the Mayo Clinic, healthy adults should not consume more than 400 milligrams of caffeine in a day. That equals about 4 cups of coffee, 10 cans of soda, or 2 energy drinks. Anymore than that and you might be prone to the following side effects:
- Nervousness
- Restlessness
- Faster Heartbeat
- Irritability
- Insomnia
Caffeine In Coffee
- Brewed, 8 oz., 95-200 mg
- Brewed, single serve 8 oz., 75-150 mg
- Instant 8 oz., 27-173 mg
- Espresso, 1 oz., 47-75 mg
Caffeine In Soft Drinks
- Coca-Cola, 12 oz., 23-35 mg
- Diet Coke, 12 oz., 23-47 mg
- Pepsi, 12 oz., 32-39 mg
- Diet Pepsi, 12 oz., 27-37 mg
Although caffeine use may be safe for adults, it’s not a good idea for children. And adolescents should limit themselves to no more than 100 mg of caffeine a day.
Even among adults, heavy caffeine use can cause unpleasant side effects. And caffeine may not be a good choice for people who are highly sensitive to its effects or who take certain medications. However, caffeine in moderate amounts, such as those in your vending machines, can be managed by most adults. Another option is to offer teas that are herbal, which do not contain caffeine.
