It's actually there since day one: Raw food and races

3% bonus to the stat given by the food.. If you're eating it with the right race.
Frankly it doesn't make a huge difference, it's just a 5min buff like Protect

Used to be 5% when we were able to alter our stats to trigger Divine favor.. Or with a +3 favored raw food.
I believe something will change in 1.21 though, let's see what happens.
