The Top 10 Unexpected Uses For Soy

The untold story of the top 10 unexpected uses for soy — tracing the threads that connect it to everything else.

When most people think of soy, they picture tofu, edamame, or maybe a soy latte. But the truth is, the humble soy bean has a far more expansive and surprising history than you might imagine. From the secret history of World War II to modern-day biofuel, soy has been quietly shaping the world around us in ways we never expected.

The Soy That Saved Britain

In the darkest days of World War II, as Britain stood alone against the Nazi onslaught, the future of the entire free world hung by a thread. With food supplies dwindling and the German U-boats cutting off vital shipping lanes, the country faced the very real prospect of mass starvation. But then came an unlikely hero: the soy bean.

Through a little-known program spearheaded by the Ministry of Food, soy was quickly adopted as a versatile substitute for rationed staples like meat, dairy, and cooking oil. Soy flour was used to bake "National Loaves", soy milk nourished children, and soy-based margarine became a pantry essential. In fact, soy played such a crucial role in sustaining the British population that by 1945, the average citizen was consuming over 30 grams of soy protein per day.

The Plastic That Grew on Trees

As the war drew to a close, scientists quickly realized that soy's unique properties could be harnessed for more than just food. In 1946, researchers at the newly formed U.S. Department of Agriculture unveiled a groundbreaking discovery: soy-based polymers could be used to create a wide range of durable, eco-friendly plastics.

From car parts to packaging materials, soy-derived "plastics" soon began appearing in everything from appliances to toys. By the 1960s, soy-based "plastic wood" was even being used to build entire mid-century modern homes. Though petroleum-based plastics would later eclipse soy in mainstream production, the soy-plastic revolution of the post-war years laid crucial foundations for today's growing bioplastics industry.

The Soy That Fueled the Space Race

As the space age dawned in the 1950s, NASA faced a daunting challenge: how to fuel the rockets and feed the astronauts for long-duration missions. The solution, it turned out, lay in an unlikely source: the soy bean.

Soy-based fuels were found to be not only clean-burning and efficient, but also remarkably stable – crucial for the rigors of space travel. Meanwhile, concentrated soy protein became a dietary staple for astronauts, providing essential nutrients in a compact, lightweight form. In fact, soy was such an integral part of the early space program that the iconic Tang orange drink was initially developed as a soy-based meal supplement.

Soy Goes Global

As the 20th century progressed, soy's versatility and adaptability allowed it to spread far beyond its East Asian roots. In the 1970s, the "Soybean Boom" saw soy production skyrocket across North and South America, fueled by growing demand for animal feed, biofuels, and processed foods.

Today, soy is a global agricultural powerhouse, with the United States, Brazil, and Argentina together accounting for over 80% of world soy production. From tofu to biodiesel, the humble soy bean has become a ubiquitous presence in nearly every corner of modern life.

The Future of Soy

As the world grapples with challenges like climate change, food insecurity, and the transition to renewable energy, soy's unique properties continue to make it an invaluable resource. From the development of advanced bioplastics to pioneering research into soy-based meat alternatives, the future of soy appears brighter than ever.

Whether it's fueling our rockets, clothing our bodies, or feeding our families, the soy bean has proven itself to be a remarkable, multifaceted powerhouse. And as we continue to uncover its untapped potential, there's no telling what other unexpected uses for soy may yet emerge.
