I think y'all are off track. Here are my thoughts, since you asked...
1)People with a crap balance of bacteria do great with low carb, until they can restore healthy flora: they're no longer feeding the beast. Logically, if you have relatively healthy gut flora, low carb would weaken the good guys.
2)Some of the problems with wheat are not from hybridization, but from the relatively new technique of spraying roundup on a ripe crop, full coverage, to kill all the plants so they can be harvested more efficiently. Does roundup affect health? Hmm, I wonder. Does it interact with wheat lectins and all that good 'healthy whole grain' goodness? I'm hypothesizing yes.
What other crops get the royal roundup treatment? Chickpeas, lentils, beans, potatoes, canola--all those "problematic" foods. Maybe it's not our macronutrients making us sick. Maybe it's herbicide exposure? Who knows.
3)Breast milk is the ideal food for mewling little 8 lb. babies (unless mom can't get off the gin and Virginia Slims). Its composition changes--it's a subtly communicative 'food' that changes as baby's needs change. To take its macronutrient profile and extrapolate that to grown men is probably not useful. Insert breast puns here.
4)Sugar is AWESOME. By my tag, you can see I'm a mom, and there is nothing funner for kids than to go batshit crazy on sugar (free-trade, ethically sourced, etc, etc). They love it! Come babysit two hours later. It's not pretty.
