Please expand on your point.
I may not be educated on the topic but I've spent a lot of time with two people that are very very well educated on the topic and I can't say I've ever heard them say it's antiquated.
If people actually followed it they would be eating much more nutritious and healthier than any fad diet.
Shirk is right. What my mom made for meals in the house and for pack lunches had everything we needed. There was minimal pre made stuff. And despite all the Ass Tripe about blood diets and whatever nonsense we where all healthy. We even ate gasp butter and whole eggs. We ate rice all the time and no problems.
Stuff like this is all about selling books nothing more. And please tone down the whole eating grains is evil crap. Many cultures around the world eat alot of this. Kalenjin eat rice by the pound while the Tarrahumara eat corn. Personally I think the problem around grains is individual tolerance levels.
