## 800 pounds each
US farmers are projected to harvest a record 4.52 billion bushels of soybeans in 2026. That works out to roughly 800 pounds of soybeans for every single American.
## Hiding in plain sight
Few of us sit down to a bowl of soybeans. Soybean oil is in dressings, mayo, baked goods and infant formula; lecithin emulsifies chocolate and bread; soy protein fills energy bars and canned soup.
## A very old Chinese crop
Chinese farmers domesticated the soybean from a wild ancestor between 6,000 and 9,000 years ago. By the first millennium B.C.E. it was one of the recognized "five grains".
## A sailor's souvenir
In 1764 an English sailor, Samuel Bowen, brought soybeans to Savannah from China. He patented a soy sauce method in 1767, then the whole venture faded after his death.
## Government plant hunters
Around 1900 USDA explorer Frank Meyer gathered dozens of Chinese varieties. Researchers Piper and Morse tested them in Virginia, then shipped the best to experiment stations nationwide.
## Crushing changes everything
Americans first grew soy as livestock forage. Industrial crushing in the 1910s split the bean into two commodities: protein meal for animals, and oil for margarine, paint and soap.
## Ford's other obsession
Fortune noticed in 1933 that Henry Ford cared about the soya bean as much as the V-8. He planted 300 varieties on 8,000 Michigan acres, hunting for car parts.

## A car made of beans
Soy oil went into Ford paint, soy meal into molded plastic. By 1935 every Ford car used about a bushel, and in 1941 he unveiled a Soybean Car with 14 soy plastic panels.
## The vile soybean lunch
Ford fed 30 reporters soy puree, soy cheese, soy coffee and apple pie in a soybean crust at the 1934 Chicago expo. One employee called the test biscuits the worst thing he ever tasted.

## War made it ordinary
Cut off from imported fats, wartime processors turned to soybean oil. Postwar livestock demand for meal left a river of cheap oil that manufacturers had to find a home for.
## Butter loses to margarine
Hydrogen turned soy oil into shortening and margarine. Between 1942 and 1972, butter fell from 16.4 to 5 pounds per person while margarine climbed from 2.9 to 11.1 pounds.
## Now it fuels the bus
By 2008 soybean oil was about 80% of America's edible oils. Federal renewable fuel rules, tightened again in March 2026, now pull it into biodiesel and jet fuel.

> his obsession with the crop looks less eccentric than prophetic
## Key takeaway

Soy conquered the American diet not by winning us over, but by becoming invisible inside cheap processed food.
