Hey Kello, that was good advise. You've covered most of what I wanted to say.
Louise,
It's hard to explain how we feel when we have a flareup.
I'm the same as Kello and a lot of others on this site, I tend to go for comfort foods. You've got to remember that we have a love/hate relationship with food.
A lot of us get diagnosed with anorexia alongside Crohns.
This is simply because our brain tells us that if we eat, we get pain... so don't eat.
Then we get cravings, through lack of nourishment.
I was told by a dietitian once to eat whatever I can during Flareups, simply to keep myself nourished. (She was a girlfriend at the time, so perhaps she was telling me what I wanted to hear 
)
I tend to eat little and often, I snack all day during a flareup. That way I don't starve myself.
It's so hard to explain to laymen/women how our relationship with food works. Or doesn't work.
Don't be too hard on him. As Kello earlier, traditional foods that are supposed to be beneficial, are actually the opposite for us.
A very good example she has given, is fibre. You even mentioned in your post the he doesn't eat a high fibre diet.
This isn't helpful to a lot of us.
We are sometimes advised not to eat too much fibre to avoid blockages.
This is a good example of a food type most people associate with a healthy diet for bowels.
My wife knows that my diet is not ideal for a healthy lifestyle, but she also recognises that my body tells me what I need. So in general, she leaves me to it.
It's not easy living with a Crohnie, he's lucky you care enough to seek us out.
I hope you'll find enough information here to understand our predicament.
