Can coffee drinking prevent dementia? What about tea? Which one is better? As we learn more about the causes of dementia, answers to these questions are becoming clearer. Coffee and tea contain caffeine. The widespread availability of foods containing caffeine has led experts to suggest that 80% of all people in North America have measureable levels of caffeine in their brains from embryo to death. Thank goodness that something good does come from this situation.
Recent studies have confirmed that coffee drinking significantly lowers the risk of developing Parkinson's disease. This effect requires about five to six cups of coffee per day for many years and appears to be mostly beneficial only to males primarily due to the lower levels of estrogen. Women benefit from coffee-drinking in other ways, particularly with regard to a reduced incidence of type-2 diabetes. Overall, people who drink substantial amounts of coffee daily tend to live longer than people who do not. Coffee drinking has been correlated with a reduced incidence of colon cancer and liver cirrhosis. Recent evidence suggests that moderate coffee-drinking of about two to three cups each day might reduce your chance of developing Alzheimer's disease.
