Coffee and tea drinkers are less likely to develop type 2 diabetes says a new study that was published in Archives of Internal Medicine. The study shows that people who have three or four cups of coffee or tea a day lower their risk of the type 2 diabetes by at least 20%. It is probably antioxidants like lignans and chlorogenic acids that are involved with this magic trick. One thing is for certain it is not the caffeine, because decaf coffee has the greatest effect.

Dr. Kaijun Niu, at Tohoku University Graduate School of Biomedical Engineering in Sendai, and his colleagues found that men and women who are aged 70 and older and drank four or more, versus one or fewer, cups of green tea daily were 44 percent less likely to have symptoms of depression. This means that drinking several cups of green tea every day will very likely improve your spirits (like a true scientist, Dr. Kaijun Niu suggests further studies before any strong recommendations can be outlined). Also several prior studies have linked green tea consumption to reduced levels of psychological distress, so this information is very solid. Furthermore, through history, green tea has been associated with positive effects to both body and soul.

What makes Dr. Kaijun Niu’s research findings even more interesting is that if green tea was to be substituted with black tea, oolong tea or coffee then there are no beneficial psychological effects. What seems to explain this is the amino acid theanine, which apparently has soothing effect on the brain. Looks like all kind of treatment and processing of tea will diminish the nutritional value of the tea. Naturally this is especially true for coffee, which is roasted. After reading about this study, I’m willing to make the recommendation that we should always drink and eat as lightly processed beverages and foods as possible for example berry powders.
