They assume, to appeal to people, that they will go back to those foods, and probably want to show them how to proberly do it.
These are published books, they say things like the fiber comment becuase it is believed by almost everyone, and like someone eles mentioned, they need to appeal to the consumer. Plus, fiber is good for you...BUT that in no way would mean you have to have it to be healthy. I think just want to show it can be had, or is healthy, but it prob. is not NEEDED per say.
Honestly, they prob. have tons of studies shown for super healthy/happy people eating only meat/fat/protien...lol...BUT no one would ever start screaming that from the hill tops, becuase the economy would crash.
People are not stupid though, anyone can try and see for themselves, (anyone who has tried meat/eggs type things can see how after a week or so your health, mind and body improve DRASTICALY) someday it will be common knowledge that these things were never needed, but people will always eat them. Becuase they are EVERYWHERE, tempting and people like the pleasure of eating. That is also my guess to why they would give a plan to eating them agian.
Even I, after knowing the benefits of Meat/eggs type eating, still fall off from time to time...but I always go back to a very low carb way of eating.
What have you guys found in your diets?? What are your thoughts??
Remember, how much money is made from junk, sugar, food and such in the world...I don't think anyone would be promoting something that goes agianst the big power houses, like "healthy" grains, fruits and Veggs., and stuff like that, becuase it has been around and regarded as healthy for so long...but I bet if that stuff was taken away, all the sudden sickeness and mental health problems would plumet, there would be no such thing as fat people and crime would probably drop.
Honestly though, food is food, but what the world really needs....is GOD.
He is our only hope...for ANYTHING in life. Everything else will leave you empty...fiber or no fiber
