I've read a couple of things claiming that allowing your pasta to cool and then reheating it significantly changes its glycemic index resulting in a much lower blood sugar spike after eating.
This sounds too good to be true to me, I enjoy eating pasta and would choose to eat it on a more regular basis if it was less likely to result in that 'post-lunch tiredness' due to no sugar crash. Also, considering my day job is sitting at a desk all day, would this likely aid weight loss (or rather, reduce weight gain)? Is this a big deal?
