ODO’S EXPERIMENT

We think of seawater as salt water, but when we think of salt, we think of just one thing: sodium chloride. In truth, the sea contains many salts—and many other things. Sodium chloride represents only about 78 percent of the mineral content of seawater, yet refined salt is very nearly 100 percent sodium chloride. In other words, the mineral content of refined salt is wildly disparate from that of seawater, in which life thrives.

The salt maker Koshin Odo once performed an experiment to explore the value of natural salt to living organisms. He picked up a bunch of crabs off the beach. He put some of them in salt water made from a refined salt manufactured through ion exchange and vacuum evaporation. The crabs died almost right away. Some of the crabs he put in salt water made by combining fresh water and unrefined rock salt. The crabs died within two days. Then he made salt water using some of his own Aguni salt. The crabs lived. Furthermore, the aquarium holding the crabs began to produce more life, presumably from microscopic organisms already living on the crabs. Koshin Odo believes that the same subtle chemistry essential for the very survival of marine animals offers benefits to humans as well.
