article imageSoybeans may slowdown cancer

By Tim Sandle     Apr 1, 2013 in Health
Scientists have demonstrated that peptides isolated from certain types of soybean can inhibit the growth of human colon, liver, and lung cancer cells.
New research indicates that peptides, derived from soybean meal, inhibited the growth of a high percentage of human colon, liver, and lung cancer cells. This related to studies undertaken in test tubes.
Soybeans are a species of legume native to East Asia, widely grown for its edible bean which has numerous uses. Soybean meal is the product leftover once oil is extracted from soybean seeds.
For the research, scientists isolated gastrointestinal-resistant peptide fragments from two soybean lines high in oleic acid (which had previously found to suppress a gene implicated in certain breast cancers). The peptide was then tested against different human cancer cell lines. The peptides from soybeans high in oleic acid inhibited cell growth in 73% of colon cancer cells, 70% of liver cancer cells, and 68% of lung cancer cells tested.
The results suggest that peptides from elected soybean lines could be a source of bioactivity against cancer cell proliferation. However, studies in test tubes do not necessarily lead to similar successes when trials are carried out on animals or, later, in people.
The study has been published in the journal Food Research International and the research was carried out at the University of Arkansas in Fayetteville.
