I suppose its dependant on what we considered "comfort"........
Actually, this has more to do with how you were raised, which I guess is where most people get the idea of comfort food. Over time the body becomes accustomed to certain spices, sugars, flavor profiles, and fat content. It's especially an issue with low income families, or people with no time.
The cheapest, fastest food you can get in America is almost ALWAYS fatty and fried. It usually uses lower grade products and over spice them so you can't taste it. However, it's easier and cheaper, so it's often what's purchased. And things like this is one of the leading causes of obesity.
Many times, if you see someone who is extremely obese but having trouble making ends meet, they are not spending money on food like it seems. They're spending 48 cents on a packet of Ramen instead of $10 on good noodles, a healthy tomato sauce (made with real tomatoes, not processed paste), and a salad with a light dressing.
When I was born, two of my aunts had gotten a divorce and lived with my parents. There was 4 adults and 13 kids in one home while they tried to get their lives together. Food was filling, with lots of carbs and fillers, and could be made in a few easy steps.
Chicken nuggets and mashed potatoes were staples because they could be done while corralling an army of children and teenagers. So it's a comfort food to me because it's what I grew up on. That's not to say that's my favorite meal. I, now, love the taste of raw vegetables, sushi, and most Weight Watchers recipes are pretty good.
But when I think comfort, I think warm, filling, fattening, and usually some form of potatoe because we've got a lot of Irish in us.
