"Purple
Miracle" |
| Japanese
investigations reveal that purple corn is the new natural
weapon against colon cancer.
|

The corn, sacred food of
the Incas, keeps surprising us. This time is the purple corn,
the foundation for our famous “chicha morada”
and her sister “la mazamorra”. According to studies
done at the University of Nagoya by a group of researchers
in the Faculty of Medicine and headed by Professor Tomoyuki
Shirai, have established that the pigmentation of the purple
corn avoid the development of cancer in the large intestine. |
This study could not be more
promising for the battle against cancer, but also for its
impact towards the local economy. Peru is the only country
worldwide with commercial sown land of purple corn. There
is an estimated 5,000 to 6,000 sown hectares with a production
of 3 to 6 tons per hectare. However, these numbers are inferior
compared with the 270,000 hectares of yellow corn, for instance..... |
| Mainichi Shimbun, a Japanese newspaper,
published news about this discovery. In lab tests, rats were
given food mixed with a natural carcinogenic substance, found
on burnt meats and cooked fish, along with a 5% of purple corn.
|
|
The result was that out of
20 rats that were given only the carcinogenic substance, 17
(85%) developed cancer to the large intestine, vs. only 8
rats (40%) that were given purple corn. |
