As much as I love the idea of eating mass quantities of soy and seitan to stay on the zone, I'm afraid it'll never happen. I like my food to suffer before I eat it.
Back on topic though, it has always been a belief of mine that research all too often simply reinforces the status quo. Scientists, doctors, researchers, etc are afraid of losing credibility by challenging accepted beliefs, and so their research is therefore biased and typically aimed at further proving previously determined "facts." This is why I love the studies where they're testing something and inadvertently find something else.
According to all the books I have and all the men's health, men's fitness, men's whatever articles I've collected over the years, we should all be eating high carb and low fat diets. This is simply not true. I've done high carb diets. I've done 3,500 calories a day with pastas, breads, and sports drinks. I let the numbers speak for themselves. Since abandoning high carb "sport" diets, my strength has gone up, I've gained considerable muscle, and I've lost body fat. My performance on a high carb diet doesn't even compare to my performance on a high fat diet. For whatever reason though, the medical field and much of the sport world still think that high carb diets are the way to go. But you're absolutely right, research and reality say two different things. Alot of things are that way though, just like how helicopters and bumblebees can't fly.
