According to analysis by InfluencerDB, there is a clear leader in the world of food on Instagram. The English celebrity chef, Jamie Oliver, with over six million followers has by far the biggest food-based account. With such wide reach and exposure, should a marketer be lucky enough to sponsor one of his posts, InfluencerDB calculates that this would have a worth of $27,406. While this compares to $580,920 for soccer star Cristiano Ronaldo, it is still impressive for someone moving primarily in the world of food.
