High carb wouldn't be good for me under any circumstances because I would become a diabetic (runs in my family). Years ago, the governmnet foisted the pyramid food plan on us. It is interesting to note that dietitions and other experts of that day believed the pyramid to be dangerous to health and so it is. Even children get type II diabetes today. Also, many Americans have sedentary (office) jobs: no need to pile on carbs which become fat. Eating a high carb low fat diet caused me to be constantly hungry and gain 35 lbs in four years. I have now lost 25lbs of this weight low carbing. I have no sympathy for these food companies. It has been known for quite a while that corn syrup is very bad for you, but they continue to use it. By the way studies have now shown that low carb is healthier than high carb. You may not want to hear this, but pasta is not good for you. You were lied to.
This started out as an economy related thread. I said that those who excercised alot or had manual labor jobs got the most out of pasta carbs. Therefore, the worldwide pasta industry should not suffer much because of our diet fads. I took into account the relative affordability of pasta carbs and the physical energy benefit per dollar/pound/peso/whatever. I stand behind that.
If you have medical problems of course the equation changes and you are the exception. As far as me getting lied to, I didn't depend on anybody else and my personal results are truer than anything you can recite.
