Thanks! It's a really interesting topic and I was excited to learn more. But I'm not sure the writer offered much to support their explanation for why these tropical spices are so closely associated with winter time in the north.
For example, I was underwhelmed by the "cinnamon is an antidiabetic, so it'll help process all those sugary treats you're eating over the holidays" fact. Does that really explain why cinnamon is associated with this season from a historical perspective? I can't say for sure that past generations weren't adding cinnamon to holiday foods because they knew it was an antidiabetic. But I'm going to continue doubting it until I see something persuasive.
