T. R. Reid has just published a new book called The Healing of America that compares American health care to health care in other countries. One comparison is with Japan:
The world champion at controlling medical costs is Japan, even though its aging population is a profligate consumer of medical care. On average, the Japanese go to the doctor 15 times a year, three times the U.S. rate. They have twice as many MRI scans and X-rays. Quality is high; life expectancy and recovery rates for major diseases are better than in the United States. And yet Japan spends about $3,400 per person annually on health care; the United States spends more than $7,000.
Life expectancy is better. Even though the Japanese smoke more than Americans. Is it all those MRI scans? (Which in Japan cost a small fraction of what they cost in America?) Or all those trips to the doctor (where, by American standards, nothing appears to happens — that is, expensive drugs are rarely prescribed — judging by overall costs)?
I believe that that Japanese do so much better because of a factor that Reid probably doesn’t consider: They eat tons more fermented food than Americans do. In a Tokyo restaurant, the woman sitting next to me, a nurse, said she believes that regular consumption of fermented foods is important for health. Does everyone in Japan think this? I asked. A large minority, she said.
The eating habits of the Japanese, as far as I could tell, bear this out. On a Japanese food blog, the writer described a breakfast that had five fermented foods: pickles, miso, yogurt, natto, and kimchi. The Japanese eat miso at every meal, more or less. They also eat lots of pickles. Natto is popular in some parts of the country but not others. They eat lots of yogurt; they are the country that gave us Yakult. They drink vinegar drinks. (Whereas in America only health nuts drink apple cider vinegar.) In other words, their diet is loaded with fermented foods. If I’m right about this, Japanese rates of autoimmune diseases should be much lower than American rates.
When people get sick much less, health care costs go way down.
