Raw soybeans contain a protein inhibitor, which ties up the availability of the protein.
To release the protein, the soybeans must be cooked or otherwise processed to release the protein for nutrition. Roasted soybeans are delicious and nutritious. Soybeans yield wonderful milk and meat substitutes. Get a good soybean cookbook and you will find recipes for many surprisingly delicious items. Most health food stores, or a large bookstore, will carry good books on how to prepare and serve soybeans.
