Questions & Answers

Q: Why does the US need to import coffee despite being the largest buyer?

The US is outside the coffee belt, where coffee trees can thrive. Therefore, it has to import coffee to meet the demand of its population.

Q: How does caffeine benefit the coffee tree?

Caffeine in coffee trees acts as an insecticide, repelling or paralyzing bugs that may harm the plant. While it is not clear if the insects experience a "caffeine high," caffeine effectively serves as a defense mechanism for the tree.

Q: Can caffeine be lethal to humans?

Technically, caffeine is lethal, but the dosage required for a 50% chance of death is extremely high. For healthy adults, it is nearly impossible to consume a lethal dose of caffeine through coffee alone. Recorded deaths from caffeine are usually associated with diet pills, pure caffeine consumption, and excessive intake.

Q: Does caffeine cause addiction?

Caffeine does cause addiction, but it is a physiological addiction rather than a psychological one. Rapid withdrawal may result in crankiness and headaches, but caffeine's positive effects, such as increased focus and improved memory, make it desirable to continue using.
