Food Therapy: Coffee Intake in reduced Risk of Stroke, Particularly in Women

By Kyle J. Norton


Coffee, second to green tea is a popular and social beverage all over the world, particular in the West, made from roast bean from the Coffea plant, native to tropical Africa and Madagascar.

A stroke is medical condition characterized by interrupted blood supply, thus reducing oxygen and nutrients delivery to the brain, resulting in death of brain cells.

Intake of coffee and coffee caffeine may have a profound effect in reduced risk of stroke incidence, a renowned institute study suggested.

In a third National Health and Nutrition Examination Survey (1988-1994; NHANES III) data to examine coffee consumption and stroke with participants aged ≥17 years old, researchers found that

coffee intake of this population showed a significantly inverse association to  stroke risk incidence,  regardless to smoke status.

Interestingly, the study also discovered that frequent coffee drinkers displayed a less occurrence of heart failure, diabetes, and hypertension but risk of high cholesterol for those consuming ≥3 cups per day. 

Dr. Liebeskind DS, the lead author said, "Heavier daily coffee consumption is associated with decreased stroke prevalence" and ". Multivariate analyses revealed an independent effect of heavier coffee consumption (≥3 cups/day) on reduced stroke".

Further more, in an analyzed data from a prospective cohort of 83,076 women in the Nurses' Health Study without history of stroke, coronary heart disease, diabetes, or cancer at baseline, with coffee consumption assessed first in 1980, then repeatedly every 2 to 4 years, and follow-up through 2004, researchers at the Harvard School of Public Health filed the following results

1. The relative risk ratio of stroke in participants coffee consumption (<1 cup per month, 1 per month to 4 per week, 5 to 7 per week, 2 to 3 per day, and >or=4 per day) were 1, 0.98, 0.88, 0.81, and 0.80 repetitively.
2. Intake of coffee and coffee caffeine daily and regularly showed a significantly positive effect in reduced stroke risk after taking in to count of other favors, including high blood pressure, hypercholesterolemia, and type 2 diabetes.
3. Risk of stroke also associated stronger correlation among never and past smokers (RR for >or=4 cups a day versus <1 cup a month, 0.57) than among current smokers (RR for >or=4 cups a day versus <1 cup a month, 0.97).
4. Decaffeinated coffee intake also was associated to a trend in lower risk of stroke after adjustment for caffeinated coffee consumption.

5. Caffeine consumption of other beverage do not associate to risk or reduced risk of stroke.

The findings suggested that long-term coffee consumption was not associated to risk of stroke but modestly reduce risk of stroke.

Promisingly, a Asian study of data obtained from the Health Examinees (HEXA) Study, involved 146,830 individuals aged 40-69 years demonstrated that high coffee consumption was associated with a 38% lower odds ratio for stroke in women in compared to (none drinkers vs. ≥ 3 cups/day drinkers in women but not in men.

The expression of coffee intake in reduced risk of stroke also found greater in women who are healthy, younger, non-obese, non-hypertensive, non-diabetic, non-smokers, and non-alcohol drinkers.

Taking together, there is no doubt that intake of coffee daily and regularly have a remarkable effect in reduced risk of stroke, particular in women.
