When soy burst onto the Western food scene in the early 1990s, the possibilities for the bean seemed boundless. The protein-packed legume had potential to prevent breast cancer, increase bone mass, alleviate hot flashes. It seemed to lower cholesterol, and thus to help prevent heart disease.

Millions of dollars were poured into research, and technologists plopped soy into every food imaginable. They ground it into burgers, hot dogs and sausages (Tofurky was born). They processed it into cheese, milk and ice cream. Manufacturers added it to baby formula, and baristas foamed it into lattes.
Is there anything they haven't said was good then turned around and said it is bad?
