Lowers Stroke Risk

Caffeine consumption can also dramatically reduce the risk of one of the most fatal diseases in the world. According to numerous clinical trials, a daily dose of caffeine may help prevent the prevalence of stroke and related deaths:
1. An analysis of multiple clinical trials found that coffee consumption of 4 cups or more daily showed a preventive effect on stroke. [228]
2. In middle-aged Korean women, higher coffee consumption showed protective benefits with regards to stroke risk. [229]
3. In male smokers aged 50 to 69 years without a history of stroke, high consumption of coffee and tea reduced the risk of cerebral infarction (severe brain tissue damage caused by inadequate blood flow). [230]
4. In Japanese (aged 45-75 years) without cardiovascular disease and cancer, higher green tea and coffee consumption (greater than or equal to 4 cups per day) resulted in a significantly lower risk of stroke. [231]
5. In the Nurses’ Health Study, researchers found that long-term coffee consumption may reduce risk of stroke. [232]
6. In a study involving 34,670 women without a history of cardiovascular disease or cancer, researchers found that low or no coffee consumption was associated with an increased risk of stroke. [233]
7. Data from 9 studies showed that consumption of either green or black tea at 3 cups daily could prevent the onset of ischemic stroke. [234]
8. In patients with incident ischemic stroke and control subjects, a significant decrease in ischemic stroke risk was observed for drinking 1-2 cups of tea daily when compared with infrequent or nondrinkers. [235]
9. In young adults (17 years and above), heavier daily coffee consumption was associated with decreased stroke prevalence. [236]
