Well, perhaps not. But it is steering you towards low-calorie options when you search for recipes. Nicholas Carr on recipes, bias and search engine optimisation:
When you’re looking for a good recipe today, you probably don’t reach for Joy of Cooking or Fannie Farmer or some other trusty, soup-stained volume on your cookbook shelf.
