There's a line in the article that says food doesn't give a "high" like drugs do.
But I get literal highs off of food sometimes. Particularly beef, some fish, and other high protein meals like those. Typically, it will only happen when the meat is very well browned, a significant "crust" from the Maillard reaction, though it will occasionally happen when there's an acidic or slightly sweet side dish.
Salmon with sweet potato does it almost every time. Tuna steaks do it fairly reliably. Steaks will more often than other beef meals, but even burgers can do it.
Am I that fucking weird here?
It's a literal high. I get slightly dizzy, euphoric, giggly, and there's a distinct sense of well being and connection to the world. It isn't just being satisfied with a good meal, it's an change in mood, thinking and overall perceptions.
