In reality, the problem isn't that we haven't been putting
folic acid into flour, the problem is that we're stripping out all the folic acid in the first place. In the
United States, people love to buy and eat foods that have been stripped of the majority of their natural
nutrition. The milling process removes virtually everything that's good for you, leaving only empty calories. White flour, sugar, corn syrup... it's all the same disease-promoting stuff after it leaves the mill.
Only
whole grains are healthy grains. Whole grains contain the bran, the fiber, the oils, the vitamins and the minerals that promote human health. Instead of debating over what isolated nutrients we should
put back into the foods sold at grocery stores why don't we stop stripping them out in the first place?
You already know the answer, of course: because
healthy food has limited shelf life. And that makes it expensive for consumers and unprofitable for food producers. Most people won't buy food that's good for them for the simple reason that it costs more than healthy food.
So they'll save fifty cents right now by buying the cheap, processed food, and they'll spend a hundred thousand dollars on
hospital bills ten years later as a result. Of course, few people connect the two events. Most people are short-term thinkers.
In addition, as I'm sure you'll agree, many people just don't know any better. That's why Internet education efforts are so critical to helping people get healthy. Keep reading, keep learning. And spread the word to help others.
