Food fads, by definition, don’t last forever. BuzzFeed used Google Trends to estimate how long they live before they die out. A food trend’s lifespan below is the length of time between when it crossed 50 — the halfway mark of popularity — and when it hit 100 and began dropping. It’s not an exact science — some trends return to their former glory after a drop, some never do. With that in mind, read on for the food fads BuzzFeed tracked, in order from longest to shortest-lived.
The average length of the trends above (that aren’t still going on) is about a year and three months. Which means chia seeds and quinoa could be about to crash, and kale has exceeded all expectations.
