the kind of bread/ dough that makes your heart rate go up (in a bad way)
the two kinds of overly processed bread that make me feel the blood pumping in my veins are store-bought naan and some kinds of pizza dough. I love eating em, but damn - my body reacts bad to that over-enriched flour (at least i think that's what causes it)
Happens to me, too. As I've gotten older, I've noticed that food items made from refined carbohydrates (the white stuff) can make my heart rate go up (and then I get really sleepy); pasta, bread, rice, any white carbohydrate causes this reaction. Same thing happens when I drink wine -- two glasses and I'm done. I'm not giving those foods up, but I do have to practice moderation with them. But, that's not really a bad thing.
