The way you chew food is enough to change it from being high GI to very low GI. This alone makes the whole index completely useless. http://www.nature.com/ejcn/journal/v68/n1/full/ejcn2013231a.html
The solution should be isotonic to allow rapid emptying of the stomach and therefore absorbtion
Glycemic Index importance depends on the athlete's insulin sensitivity.
Straight maltodextrin is not too bad during exercise.
Wheat is evil unless you want a leaky gut and associated toxic effects and various automimmune diseases.
Interesting! I had no idea chewing had any effect on GI. Too bad that study is hidden behind a paywall, do you you have another link that isn't? Do you have a copy of the study you can share?
I am going to do a little google-fu and see if I can come up with some other sources or journals about this subject.
I don't follow you about wheat being evil. Wheat has been a staple in the human diet since the great leap forward. My 80 year old grandfather eats wheat daily and he is in great shape, he doesn't have to take a single type of any medication yet. He doesn't have a leaky gut or any autoimmune disorders.
I have not yet come across any legitimate sources that back up the notion that gluten or wheat is bad for you.
I have noticed there has been a lot of fad misinformation in the media lately. Gluten-free diets for non-celiacs, vaccines being bad for you, irrational fears about microwaves, a push back against dairy(people are now trying to tell me that milk is bad for us, ha) people who think here is some "cure" for cancer other than combination therapy via medical oncology
NONE of these fears are back by any legitimate studies (double-blind and peer reviewed.)
I love the internet, but I am dismayed by it's power to spread dangerous misinformation.
