Investigating the Impact of Junk Food on Blood Sugar Levels




Examine how consuming junk food affects blood sugar levels in the short term.


  • Blood glucose monitors
  • Participants
  • Junk food items (e.g., candy, soda)
  • Notebook for recording data


  1. Measure baseline blood sugar levels of participants before consuming any food.
  2. Have participants consume a standard amount of junk food.
  3. Measure blood sugar levels at regular intervals after consumption (e.g., every 15 minutes over an hour).
  4. Record the blood sugar levels in your notebook.
  5. Compare the changes in blood sugar levels over time.
  6. Analyze your findings to understand how junk food impacts blood sugar levels.
  7. Present your results in a report, discussing the health implications of consuming junk food.
