I am really superficial with my food. What does that mean exactly?
It means that I am in love with my food, and go great lengths to eat the best food available to me.
Breaking it down even further, if I don't like the taste of it, I don't eat it. I only get so many calories a day, why should I waste it on something that's rubbery, over salted, and just plain so-so? If I'm getting fast food -- it's made to order. If it's fresh fruit and vegetables, it's peak season and rightly priced. You get the idea; you don't have to be as "selective" as I am, but don't just eat anything because it's in front of you.
My food it also really pretty. It's probably the most inane detail, but it's very important. When you watch TV ads, do you ever see an ad for mushy, overcooked food? You eat with all your senses, even your ears, why not appeal to each one? I find the easiest way to achieve this is to add color to your food. How? For starters, eat an array of fresh fruits and vegetables.
Chees-y tag line: Nature's rainbow is your natural vitamin! (Or cocktail, depending on how you roll, I guess.)
Warning: music is terrible, but overall point is good.
You can also choose to eat off of great stuff. You don't have to hire a violinist or have dinner by candlelight. Functional & cool items can also make your food pretty. This is my lunch bag:
People at work love my lunch bag. It's a, *ahem*, conversational piece. Haha. Honestly, it's so weird looking, so they often ask what it is and I end up blabbing about it. (I had this one before hand, but I destroyed it :/) My point, it's okay to be a little vain about your food. In the long run, it can be worthwhile. You'll eat better, feel better, move better, etc. You'll be better.
However, I wouldn't recommend vanity for other aspects of your life.
