Advances in alternative health

So it's amazing to me how much the field of alternative health has advanced -- both in terms of its popularity and in terms of how much more we know now and the products that're available.

We've gone from cod liver oil as a source of Vitamins D and A to pharmaceutical grade fish oil that's had almost every molecule of PCBs refined out of it as a source of Omega 3. Try to find any reference to Omega 3 oils in an Adele Davis book.

We've gone from getting calcium in smoothed down tablets of limestone rock to highly sophisticated, bio-available liquid vitamins.

We've gone from relying solely on vitamins and minerals to having a vast array of herbs from all over the world at our disposal. I could be wrong, but I doubt if any herbs are mentioned or recommended in any of Adelle Davis' books. Now we know that although certainly vitamins and minerals are important, that complex molecules can perform very useful functions in our bodies.
