Food

During the Siege of Leningrad (1941–1944) in World War II, at least nine Soviet botanists starved guarding a seed bank of 250,000 food crop samples. They refused to eat a single one—rice researcher Ivanov died amid thousands of bags of rice.

Ulleungdo Island's famous pumpkin taffy was originally 'hubak taffy.' Made from the hubak tree on the island, the name was mistakenly spread as 'pumpkin taffy' due to similar pronunciation. Ulleungdo seized this and began making actual pumpkin taffy.

The "yang" (羊) in yokan means lamb. Originally a food made with lamb's blood in China, it was reinvented with red bean paste in Japan, where a 1,200-year meat ban made slaughtering sheep impossible. This version persists to this day.

During Japan's 1,200-year meat-eating ban, people devised creative loopholes. They classified rabbits as birds by calling their ears "wings," dubbed wild boar "mountain whale" to pass it off as fish, and claimed ducks were fish because they had webbed feet.

In 1981, the Reagan administration in the USA tried to classify ketchup as a vegetable to meet school lunch nutritional standards after cutting budgets. The backlash slogan "Is ketchup a vegetable?" became so powerful that the policy was reversed.

In 2024, an Indiana court in the USA ruled that tacos and burritos are "Mexican-style sandwiches." A taco shop owner had fought a lawsuit for about 18 months to open a second location on land restricted to "sandwich bar-style restaurants."

In 1945, engineer Percy Spencer noticed his chocolate bar had melted near a radar device. He tried popcorn—it popped. An egg exploded. Realizing microwaves heated water molecules, he patented the idea, and the world's first microwave oven was born.

Seasonings slow food spoilage not by killing microorganisms, but by stealing their water. Salt and spice molecules bind with free water in food, lowering its 'water activity.' Even if water is present, microbes cannot use it.

Ramen noodles are yellow because of added vitamin B2. In the 1980s, ramen companies began adding vitamin B2 to address nutritional concerns. The alternate name for vitamin B2, "riboflavin," contains "flavin"—derived from the Latin word "flavus," meaning yellow.

Korea's 17th-century text 'Jibong Yuseol' records that chili peppers were introduced from Japan, while Japan's 'Yamato Honzō' claims seeds were brought back from Korea during Hideyoshi's invasion. Both countries believe chili peppers came from the other.

The word 'ketchup' comes from '膎汁' (kôe-chiap) in the Chinese Min Nan dialect, meaning 'fish sauce.' It was originally a fermented fish and shellfish sauce—tomato ketchup was not invented until 1812.
