An article in Scientific American has raised the question as to whether drinking eight glasses of water a day is fact or fiction. I would like to offer some insights into this. Originally George Ohsawa recommended limiting liquid consumption. This recommendation was changed years ago by Michio Kushi to drinking a comfortable amount to satisfy your thirst.
In the modern American diet almost everything is dry. Meat, chicken, cheese, pizza, bagels and chips are all dry. Coffee, alcohol and caffeinated drinks are dehydrating. When you have a plant that is too dry, water runs right through, even though the water is what it needs most. It takes time until the plant can accept and utilize the water. It is a similar situation with the modern diet. When we consume so many dry foods, liquids tend to run through us. We have more of a need to drink continually as see all the time these days.
In traditional diets as well as the macrobiotic way of eating most foods are wet. Cooked grains, beans, vegetables, soups, salads, fruits, etc. all have a high water content. The most important liquid we consume is through our food, especially when well chewed. This liquid does not just pass through us. When we drink some water or mild tea we easily become well hydrated.
In order to stay well-hydrated, try to consume a variety of cooked foods that are naturally moist and refreshing in addition to drinking a comfortable amount of liquid.
