2. What primary sources did you find (e.g., transcripts, videos of politician speeches, tweets from public figures, scientific studies)? For each source, write at least one or two sentences explaining what you learned. Include all links.

Investigated caffeine and calcium metabolism, concluding that adequate calcium intake cancels out any minor calcium loss caused by caffeine
3. What secondary sources did you find (e.g., newspapers, magazines)? Only use secondary sources if sufficient primary sources are not available. For each source, write at least one or two sentences explaining what you learned. Include all links.

Caffeine guidance for the young. Focused on sleep.
4. What potential biases or interests might each of your sources have?
People and doctors tend to prefer stimulant free children
Social stigma
Observational studies might be confounded by lifestyle factors
No strong financial incentives
5. What evidence supports the claim you are fact-checking?
Caffeine can reduce appetite or disrupt sleep, which could indirectly affect growth if nutrition or rest are impaired
Very high caffeine intake could slightly increase calcium excretion if calcium intake is inadequate.
Animal studies using extremely high doses sometimes show growth effects, but these doses exceed typical human consumption.
Caffeine causes a higher nutrient and sugar requirement
6. What evidence undermines the claim you are fact-checking?
Longitudinal human studies show no reduction in height or growth from caffeine.
Adequate calorie, protein, calcium, and sugar intake mitigates any suppression
