Washington: Proteins found in soybeans can significantly inhibit growth of colon, liver and lung cancers, scientists, including Indian-origin researchers, have found.
Peptides derived from soybean meal significantly inhibited cell growth by 73 per cent for colon cancer, 70 per cent for liver cancer and 68 per cent for lung cancer cells using human cell lines, according to the study by University of Arkansas researchers.
Soybean meal is a bi-product following oil extraction from soybean seeds. It is rich in protein, which usually makes up around 40 per cent of the nutritional components of the seeds, and dependent on the line can also contain high oleic acid (a monounsaturated omega-9 fatty acid).
The study conducted by Srinivas J Rayaprolu, Navam S Hettiarachchy, Pengyin Chen, Arvind Kannan and Andronikos Mauromostakos was reported in Food Research International published by Elsevier.
Researchers studied the role soybeans could have in the prevention of cancer. Using a variety of soybean lines which were high in oleic acid and protein, the researchers looked to monitor bioactivity between the peptides derived from the meals of soybean and various types of human cancer cells.
The research shows that the selected high oleic acid soybean lines could have a potential nutraceutical affect in helping to reduce the growth of several types of cancer cells.
