- 122,000 from Nurses’ Health Study, NHS II (1991–2007) -documented 7,269 cases type 2 diabetes
- Diet was assessed every 4 years using a validated food-frequency questionnaire. Self-reported cases of incident type 2 diabetes were validated by supplementary questionnaires.
- RESULTS:
- 1 extra cup/day (average: 1.69) – 11% reduced risk 4 years later compared to those who did not change
- 1 less cup/day (average: 2) – 17% increased risk 4 years later compared to those who did not change
- Not seen in decaffeinated coffee or in tea consumption had no impact
- Best result in those who consumed 3 cups/day – 37% lower than those who consumed 1/day
