Soybean Protein for Cancer Prevention

Soybean seeds are a rich source of protein as well as oleic acid. Srinivas J. Rayaprolu, from the University of Arkansas (Arkansas, USA), and colleagues monitored bioactivity between peptides derived from the meals of various soybean lines and a variety of types of human cancer cells. The study showed that peptides derived from soybean meal significantly inhibited cell growth by 73% for colon cancer, 70% for liver cancer and 68% for lung cancer cells using human cell lines. Submitting that their data is the “First study to report anti-cancer bioactive peptides from high oleic acid soybeans,” the study investigators conclude that: “Soybean peptide fractions can thus be a source of bioactivity against colon, liver and lung cancer cell proliferation.”
