Health Benefits of Traditional Roasted Coffee
Recently, more and more scientific studies have been published indicating various health benefits from coffee consumption. Many involve roasted coffee as well as green coffee. Much of this recent news contradicts previous beliefs about potential negative effects from drinking roasted coffee.
Some contradictory evidence has to do with the filtering of coffee. Coffee brewed using paper filters removes detrimental oily components in coffee called diterpenes, which are present in coffee that has not been filtered.
There are 2 types of diterpenes and both have been associated with an increased heart disease risk because these substances cause elevated LDL cholesterol, which is the bad cholesterol. But the use of paper filters mitigates this issue.
Metal filters, however do not remove the diterpenes and thus does not alleviate this risk. So, coffee drinkers should make sure there coffee is brewed through paper filters.
Wikipedia, as of August 2012, has this information…
“Coffee consumption has been shown to have minimal or no impact, positive or negative, on cancer development researchers involved in an ongoing 22-year study by the Harvard School of Public Health state that “the overall balance of risks and benefits [of coffee consumption] are on the side of benefits. For example, men who drank six or more cups of coffee per day were found to have a 20% reduction in developing prostate cancer.
Other studies suggest coffee consumption reduces the risk of being affected by Alzheimer’s disease, Parkinson’s disease, heart disease, diabetes, diabetes mellitus type 2, cirrhosis of the liver, and gout.
A longitudinal study in 2009 showed that those who consumed a moderate amount of coffee or tea (3–5 cups per day) at midlife were less likely to develop dementia and Alzheimer’s disease in late-life compared with those who drank little coffee or avoided it altogether.
It increases the risk of acid reflux and associated diseases.”
And it goes on from there. There are various links throughout this section of the website to take you to many of the sources of information on the subject of the health benefits as well as possible negatives of drinking roasted coffee.
Coffee and Antioxidants
The coffee cherry fruit is extremely high in antioxidants and has a higher level of antioxidants than blueberries or pomegranates. Both of those fruits being known for their high antioxidant value.
Antioxidants are considered important because the free radical theory of aging suggests that antioxidants help neutralize the negative effects of free radicals. We’ll present more on the subject of free radicals in another article, at a later date. But to synopsize, some scientists believe the positive effect of antioxidants on free radicals may help protect human cells from damage caused by free radicals.
