Proteins found in soybeans have been shown to block the growth and development of colon, liver, and lung cancer tumors, suggesting the ubiquitous bean offers promise as a potential new weapon against cancer.
A new study by University of Arkansas researchers, published in the journal Food Research International, indicates peptides derived from soybean meal inhibited cell growth by 73 percent for colon cancer, 70 percent for liver cancer, and 68 percent for lung cancer cells in the laboratory.

To reach their conclusions, researchers examined a variety of soybean lines — including those especially high in oleic acid and protein — to determine the impact of peptides derived from soybean meal on various types of human cancer cells.
The results showed that certain soybean lines with high levels of oleic acid were the most effective against the tumor cells and have great potential in helping to reduce the growth of several types of cancer cells.
Oleic acid is a monounsaturated omega-9 fatty acid believed to have significant health benefits.
Soybean meal is produced as a byproduct of oil extraction from soybean seeds.
