Apologies for such a late response to your message a while back. Here’s the paper you enquired about.
The story is basically this: that there is increasing evidence that problems with glucose and insulin metabolism may be involved in the development of migraine. A chemical that allows for blood vessels to relax (vasodilate) called nitic oxide (NO) plays a big role in vascular function and it can be measured. They have found in this study that migraineurs show greater NO stress. Furthermore they showed that this stress was correlated with hyperinsulinemia – in other words, excessive insulin levels in the blood.
So how does one keep insulin levels in the normal range and also prevent hyperglycemia (gluocse spikes in the blood) which causes insulin spikes? Don’t eat refined carbohydrate and exercise daily as Bernstein outlines: 30 minutes/day at a moderate pace where you can feel your heart working. Strength training is also important; the more muscle mass you have the better you store glucose and the less you need insulin. Strenght training doesn’t mean going to the gym and becoming Arnold Schwarzenegger but it means using your muscles in a way that you can feel them being worked. Strength training is one of the goals in the Sydney Diabetes Prevention Program I’m involved with. We encourgae participants to buy dumb bells and strap on weights that go around your ankles. They then do a routine about 4 days a week on their arms and legs. Walk up stairs instead of using the elevator etc. There’s lots that can be done to make a difference and increase strength.
In terms of diet, everyone here should be lookig at a low glycemic index version – choosing low GI carbs instead of high. Marci has found that she does well on a low carb diet (not to be confused with low GI). We don’t recommend low carb diets because they can cause problems and are very hard to stay on long-term but if you think you can stick it out, and it reduces migraines then it’s obviously worth it. But see if you can achive the same results with low GI first. Most of us are eating well anyway I’d say because a migraine diet is pretty much low GI anyway.

Let me know if this all makes sense.
