I was reading a mystery last night which bounces between the early '60's and the late '80's. The locale is a fictitious coastal town in California. One character was discussing her son's hippy girlfriends' diet and mentioned quinoa (chapter based in 1963). Which got me thinking...
I've worked with "health foods" since my volunteer days at food co-ops in the mid '70's. I don't think I heard of quinoa until the late '80's (read a brief mention of it in a travelers report of S. America) and don't recall seeing it available until the 2000's.
Maybe I just didn't notice it...the dry goods weren't my area of specialization. I've always lived on the east coast. Many "new" foods are introduced in Ca. several years before distribution channels are established in the east.
Would quinoa have been accessible in California in '63? When/how did you first become aware of it?
