Warning, conspiracy theory!
I have been pondering why the Government is so dead set on high carbohydrate diets. After reading books such as In Defense of Food, and Fast Food Nation. I have been starting to think its about control as opposed to health. With all the Subsidies already paid to farmers directly and indirectly. Its cheaper to feed us carbs and seed oils. Keeping us working and paying our taxes.
If you can produce even a small portion of your food, thats money you don't have to earn to support a lifestyle of ever increasing consumption. The man who can produce his own food is a radical who cannot be controlled.
That is all. Thank you.
