Banana

Artificial banana flavoring differs from today's bananas because it was developed when Gros Michel dominated markets. Panama disease pushed that cultivar off shelves in the 1950s–60s, and the Cavendish replaced it. Since the two taste different, the old artificial flavor now seems oddly 'fake.'

Bananas are radioactive, thanks to potassium-40, a natural isotope. A medium one decays ~15 times a second — basis of the informal "banana equivalent dose." Yet eating one doesn't raise your dose; the body sheds the same amount to keep its total steady.

Botanically a banana is a berry but a strawberry is not. A berry grows from one ovary with seeds in its flesh—bananas qualify. A strawberry's red part is a swollen receptacle, and each speck on it is actually a separate fruit holding a seed.
