Most people look at coffee as being harmful or distasteful to the health, but it also has some benefits that some people may not know about.
A few things coffee can do for a person
Coffee is also a powerful stimulant for peristalsis and is sometimes considered to prevent constipation. However, coffee can also cause excessively loose bowel movements. The stimulative effect of coffee consumption on the colon is found in both caffeinated and decaffeinated coffee.
Practitioners in alternative medicine often recommend coffee enemas for “cleansing of the colon” due to its stimulus of peristalsis, although medicine has not proven any benefits of the practice. Contrary to popular belief, caffeine does not act as a diuretic when consumed in moderation, and does not lead to dehydration or to a water-electrolyte imbalance; current evidence suggests that caffeinated beverages contribute to the body’s daily fluid requirements no differently from pure water.
Coffee consumption is also correlated to a reduced risk of oral, esophageal, and pharyngeal cancer. In ovarian cancer, no benefit was found. In the Nurses’ Health Study, a modest reduction in breast cancer was observed in postmenopausal women only, which was not confirmed in decaffeinated coffee. According to one study, coffee protects the liver from cancer. Another preliminary study found a correlation between coffee consumption and a lower risk of aggressive prostate cancer.
Coffee moderately reduces the incidence of dying from cardiovascular disease, according to a large prospective cohort study published in 2008. A 2009 prospective study in Japan following nearly 77,000 individuals aged 40 to 79 found that coffee consumption, along with caffeine intake, was associated with a reduced risk of dying from cardiovascular disease.
Reduced risk of gallstone disease
Drinking caffeinated coffee has been correlated with a lower incidence of gallstones and gallbladder disease in both men and women in two studies performed by the Harvard School of Public Health. A lessened risk was not seen in those who drank decaffeinated coffee. A recent study showed that roast coffee protected primary neuronal cells against hydrogen peroxide-induced cell death.
Coffee intake may reduce one’s risk of diabetes mellitus type 2 by up to half. While this was originally noticed in patients who consumed high amounts (7 cups a day), the relationship was later shown to be linear.
