Wake up to the Power of Coffee

The studies below found some significant facts regarding health effects of certain food.  This is an attempt by us to interpret the findings so that it could be implemented in everyday health practices.  It has to be understood that good eating habits are necessary for optimal health and that means that a variety of good foods have to be consumed every day.  We do believe that some food has medicinal value and could be used to help in the prevention and support of treatment in certain illnesses.  However, if it is not part of a good nutritious diet, it might lose its value.    Although we do believe in the power of natural food, we absolutely do not claim to cure any disease through the consumption of specific foods.

This study analyzed the findings of 9 studies done from 1966 to 2007 to see what the link is between coffee consumption and liver cancer.  The researchers found that increasing your coffee consumption with two cups of coffee per day might reduce your risk of liver cancer.

This study re-analyzed the findings of 28 controlled studies to see what the effect of coffee consumption is on the development of type 2 diabetes.  The researchers found that the consumption of both caffeinated and decaffeinated coffee seems to protect against the development of type 2 diabetes. The level of protection was even higher if more than one cup of coffee was consumed

This study was done on 953 patients with stage III colon cancer.  The researchers looked at the consumption of coffee, decaffeinated coffee and herbal tea on the recurrence of the cancer.  They found that the consumption of four or more cups of regular coffee significantly reduce cancer recurrence.  Patients who consumed herbal tea or decaffeinated coffee did not show this decrease in recurrence rate. 

From the three studies above it looks as if there is a definite link between the consumption of coffee and the prevention of cancer.  It is not shown in all studies though and therefore we also look at another study:

 

Maurice PA Zeegersa, Frans ES Tanb, R Alexandra Goldbohmc and Piet A van den BrandtaAre Coffee and Tea Consumption associated with urinary tract cancer risk?  A systematic review and meta-analysis. Int. J. Epidemiol. (2001) 30 (2):353-362.doi: 10.1093/ije/30.2.353

This was a review on 34 case control studies and three follow-up studies.  It found that the consumption of coffee is related to the development of urinary tract cancer while the consumption of tea did not have a similar effect.

This is a difficult call to make if there is evidence for and against the risk factors of a certain type of food.  As always, everyone should take responsibility for their own decision with as many facts on the table as possible.
