Once the coffee was associated with unhealthy stimulant. Today, even in the field of healthy nutrition experts suggest that moderate coffee consumption prolongs life and protects against dementia, reduces the risk of diabetes and stroke.

First in the world Japanese isolated from coffee two connections, which limit the growth of prostate cancer. We are talking about kahveola acetate and cafestol. Experiments have shown that these substances inhibit the growth of cells that are resistant to commonly used anti-cancer drugs.
The studies were conducted only in mice. Both compounds were tested on cells of prostate cancer, which were implanted 16 mice. Four of them were in the control group, four were cafestol, another four kahveola acetate, and the rest of cafestol and acetate kahveola simultaneously.
"We found that both cafestol and kahveola acetate inhibited the growth of cancer cells, but their combination works synergistically that It led to a marked slowing of tumor growth than mice in the control group, "- says Dr. Hiroaki Iwamoto, Manager research.
Academic emphasized that after 11 days untreated tumors increased by 3.5-fold (342%) and the tumors of mice treated with two substances, increased slightly more than 1.5 times (167%).
It is important to note that kahveola acetate and cafestol, found in beans Arabica. Also, great importance has method of preparing the beverage.
Scientists from the University of Kanazawa emphasize that, although the results of their experiments are promising, additional detailed investigations.
