modern food additives contain high amounts of 'natural flavorings' that are simply highly refined plant pheromones that act as attractants.

They use mass produced donuts to set traps for paid bear hunts...takes a lot of skill to kill a bear from a blind 50 yds. away when he has his head in a bucket.

It does work especially when you combine pheromones with high fructose corn syrup which is super addictive.

Here is an excerpt from a paper;

The balance of these two effects from compounds in the diet has yet to be fully established. Secondly, and more specifically, the 4-hydroxy-3(2H)-furanones associated with fruit aromas act to attract animals to the fruit, which ensures seed dispersal. In the case of humans, the coincidental synthesis of some of these compounds in foods during preparation results in these foods appearing particularly attractive through the transferred operation.

I heard of a bear breaking into a house, heading to the kitchen, and devouring at least two trays of brownies.

That's a New York bear, he'll try to bum a smoke off of you!
