The Japanese Diet. You might be wondering why we have the same word for a legislative body and an eating regimen – well, they have separate roots, and are etymologically unrelated. The parliamentary Diet comes from Latin, “dietas,” and means day. The assemblies met every day, hence the name. Food diets are based on the Greek word diaita, which means “a way of life.”

I didn’t know it either, and I got all that from other sources. I’d link, but why? Sometimes a link is just an annoyance.
