A-Z Nutrition: Caffeine

What is the buzz about caffeine?

Caffeine is a stimulant naturally present in certain foods including, coffee, tea, and chocolate. Stimulants impact the nervous system by exciting it, giving some people the feeling of alertness while others may have the jitters (1).

Cautions about caffeine!

Due to the stimulant nature of caffeine, large doses (more than 2-4 cups of coffee) can have negative health impacts for some individuals including:

  • Dehydration
  • Restlessness
  • Rapid Heartbeat
  • Headaches
  • Dizziness

For most people, moderate amounts of caffeine up to 2 cups do not have negative effects. If you are concerned about your caffeine consumption or are pregnant, please consult your healthcare provider for personal recommendations.
