Do Soybeans have Anti-Cancer Properties?

Friday, March 29th, 2013

logo1267406_mdA new study published in Food Research International by Elsevier concluded that protein found in soybeans could prohibit the growth of colon, liver and lung cancers. Soybean meal is a bi-product following extraction of oil from soybean seeds that is rich in protein making up around 40of the nutritional value of the seed depending upon the line. It can contain  high oleic acid- a monounsaturated omega 9 fatty acid.

The study looked at the role of soybeans in preventing cancer. Using a variety of soybeans that were high in oleic acid and protein. researchers monitored the bio activity between peptides derived from the meals of soybeans and various human cancer cell types.

The study showed that peptides derived from soybean meal significantly inhibited cell growth by 73% for colon cancer, 70% for liver cancer, and 69% for lung cancer. This showed that the selected high oleic acid soybean lines have a potential nutraceutical affect in helping to reduce the growth of these types of cancer cells.

 

 

 

Environmental Friendly Soy Bean Harvest and Cancer Prevention.

Friday, May 18th, 2012

Research published in ACS’ Journal of Agriculture and Food Chemistry recently concluded that soybeans soaked in warm water may become a healthier way to obtain a soy substance to  fight cancer. The substance is currently manufactured in a complicated and time-consuming industrial process that does not have the most healthy outcome.

The substance called Bowman-Birk Protease Inhibitor (BBI) has shown promise for preventing some types of cancer. Human test results included evidence from the Japanese diet  that contains large amounts of soybeans that might underpin the low cancer mortality rates in that country. A problem with the current supply of BBI is that extracting it from soybeans is a time-consuming process and requires harsh chemicals. The current researchers wanted to see if there was a better (greener, more environmentally friendly) way to obtain BBI. The found that incubating the soybean seeds in water at 122 degrees Farenheit released large amounts of BBI that can easily be harvested from the water.  The water was tested on and stopped breast cancer cells from dividing. The researchers concluded “The abundance of BBI in soybean seed extracted by incubating the seeds in warm water provides a simple and alternative method to isolate this low molecular weight protein.”
