Acai berries, noni juice, sea buckthorn extract, Peruvian maca root, wolfberries, ginseng, gingko nuts, cordyceps or caterpillar fungus, black garlic, ganoderma spores - these are all exotic supplements that claim to cure you of all ills, including cancer.

They are the exotic super foods, their effectiveness often backed by claims that they have kept past civilizations hale and hearty. Many are drawn from the diets of ancient peoples like the Mayans, but just as many have been "discovered" by new Western converts to traditional Chinese medicine.

Many Chinese used to raise amused eyebrows when they saw Western friends popping pills of gingko extract and downing gallons of goji berry (wolfberry) juice.

To the Chinese, these are everyday ingredients, to be taken in moderation, as food. And to the Chinese, food is medicine and medicine is food, a philosophy remarkably similar to that of the ancient Greek physician Hippocrates. (Moderation is part of the prescription. Too much gingko is actually toxic, as every Chinese child has been taught.)

That's the difference between Western and Chinese medicine. One cures the symptoms, while the other seeks out the root of the illness and believes a balanced body is the answer to good health.

That does not mean the Chinese do not believe in health tonics, supplements and super foods. They just have their own lists, mostly herbal, but sometimes animals and minerals.

We really don't know when we started justifying every bite we ate. In times past, mothers from both hemispheres and all longitudes urged their children to "eat more spinach because it's good for you", often pointing to the TV and Popeye the Sailor man as animated proof.

In these days of New Age nutrition, mothers still try to persuade their kids to eat more spinach, only they'll be more likely quoting liberally from online surveys and nutrition charts.

Not that it works any better than Popeye in persuading the young ones to down the dark green stuff.
