Miracle Whip vs Mayo... what changed or has it?

Recently, after YEARS of using Miracle Whip, I now cannot stand the taste or smell and have switched to mayo. I threw out several jars before I realized that no, it didn’t go bad, it has either changed or my taste for it has changed. Now I’ve switched to Best Foods mayo, for now.

I ran into a lady at the grocery who said the same thing. She no longer liked Miracle Whip. Did they change the recipe, or is it our taste buds changing again as we get older?
