inter99 looked at the association with diabetes, and found none . We know that brown bread causes less of an incretin effect than white bread, but what you seem to have is the assumption that in healthy people that that is bad. Populational assumptions seek to show correlation with diabetes, but this is a long bow to draw.
It may well be that complex as a rule is better than simple - but at the same time compare and contrast the commonly held view that complex is good in sport because of uptake with the AIS view on these things when they actually studied performance rather than applied a set of logical arguments. Its the test that matters.
If there is positives in complex carbs that is a strong, its that they tend to correlate with increased fibre - but you must remove fibre from the experiment to identify whats going on. Hell, taking protein with simple carbs has the same effect on slowing uptake as well - but no-one screams that one from the rooftops (nor labels their food as such)
Behaviourly, its a complexity that doesnt help - people think they can therefore eat more carbs as long as they are complex rather than simple - this is the wrong message IMO - thats why i wrote it above, not for the minutae of the argument but from the practical perspective of its not worth persuing - total energy is however. A carrot is carb, and so is a tablespoon of sugar, as is a banana.
Another one that jumps out for me is "organic" <<enter product you want to sell here>> for 1.4*normal price - we live in the age of widespread paranoia - "natural" is not better, its just an adjective that people get warm fuzzy feelings about and associating it makes people feel better.
The place where you will live longest, is the western country with modern medicine loads of high tech processed foods, and technology/pesticide driven agricultural practices. Within those countries, you can be at the RHS of the bell curve by exercising a little everyday and not being overweight. living to a hundred sux btw, you're body might make it, but chances are your brain will be farked by 85.
