Also, when my daughter had braces her orthodontist told me to keep pain down after tightenings, get get her some non-stick gum and let her chew it immediately after the tightening. It worked for my daughter after several painful tightenings. I would also give her the motrin 30 minutes before her appointment.
Whatever he typically eats can be dumped into a blender for a few seconds to puree it for him to eat.

It all looks yucky, but it still tastes great.
Meatloaf with mashed potatoes
Buffalo chicken strips
Hamburgers with baked beans
etc.
You get the point. If he can eat it in its' original state, he can eat it coming from a blender. He'll need to get over the "looks" department, but if he's hungry enough, he'll eat it.
He'll probably turn his nose up to a warm chicken nugget shake, but I guess if he gets hungry enough, he'll eat it. 
Would he drink smoothies (strawberries, bananas, blueberries, etc.)
I used to had braces when I was a teenager and I never cried about tightening. After 2 weeks, the doctor wanted to check on me and asked if I'm in any pains and I said no. She retightened the wiring in the braces and I never said a word. To tell you truth, I didn't even know she was retightening them. I found out after she told me what she did.
I was supposed to have the braces on for five years, but it came off after almost two years. The doctor was so surprised because I never complained and told me that I had high tolerate for pains. She was able to speed up the process of braces wearing and to this date, my teeth are still straight and perfect.
