Comparison of serum glucose, insulin, and glucagon responses to
different types of complex carbohydrate in noninsulin-dependent
diabetic patients
PA Crapo, J Insel, M Sperling and OG Kolterman

We have studied the acute effects of oral ingestion of dextrose, rice,
potato, corn, and bread on postprandial serum glucose, insulin, and
glucagon responses in 20 diabetic subjects with nonketotic, noninsulin
requiring fasting hyperglycemia. The carbohydrate loads were all
calculated to contain 50 g of glucose. The data demonstrate that 1)
dextrose and potato elicited similar postprandial serum glucose
responses whereas rice and corn elicited lower responses, with bread
intermediate; 2) postprandial insulin responses were relatively flat
but rice ingestion led to significantly lower insulin responses than
did potato; 3) urinary glucose excretion during the 3 h after
carbohydrate ingestion was greatest following dextrose and least after
rice and corn. In conclusion, there is a range in the magnitude of
postprandial hyperglycemia after ingestion of different complex
carbohydrates in diabetic patients with fasting hyperglycemia and
emphasis on the use of the less hyperglycemic starches could be of
therapeutic value in controlling hyperglycemia.

Inside Japan: Surprising Facts About Japanese Foodways
By Sally Fallon and Mary G. Enig, PhD

Japan is presented to the American public as a nation benefitting from
all the dietary paradigms deemed politically correct. Their diet is
low in fat, high in carbohydrates, devoid of dairy foods and rich in
soy foods, we are told, and for this reason the Japanese enjoy the
longest life-span in the world, with much lower rates of heart
disease, osteoporosis, breast and prostate cancer than the US.

These are partial truths and the relationship between diet and disease
in Japan is more complex than we are led to believe. Close examination
of the traditional Japanese diet proves that, although very different
from Western diets, Japanese cuisine embodies all the principles of
nourishing traditional foodways. It is rich in fat-soluble vitamins
from seafood and organ meats and in minerals from fish broth, and
contains plenty of lacto-fermented foods. Japanese preparation
techniques eliminate most of the antinutrients in grains and legumes.
As long as the Japanese get enough to eat, their diet is a healthy
diet in surprising ways.

Staples
Rice is the main carbohydrate food in Japan, consumed with every meal.
For the poor, it is the chief source of calories. However, the real
basis of the Japanese diet is not rice but fish, consumed at more than
154 pounds per person per year1-almost one-half pound per day. This is
about the same amount by weight as rice, but in terms of calories,
fish provides a greater amount for most of the Japanese.

Fish consumed in Japan come from waters surrounding the island nation
and from around the world. Japan imports millions of dollars worth of
shrimp, salmon, trout and tuna every year. In addition, carp is farmed
in fresh inland waters.

Fish is usually eaten fresh-even delivered to the door by fishmongers-
but it is also consumed in salted, dried and pickled form. Fresh fish
is grilled or baked and also eaten raw (sashimi). Generally there are
two fish courses at each meal, one of cold fish and one of hot.

A typical fish dish is hoshizakana, which is fish that has been
marinated for 20 hours in a mixture of soy sauce and sweet white wine,
then hung up for one day to dry. Then it is baked in the oven and
served plain, without any sauce.2

Soups made of fish, including the organs and bones, are considered
strengthening foods and good for anemia. Carp soup is traditionally
given to women after childbirth. It is made from the whole carp,
including the head, bones, eyes and all the organs except the gall
bladder, and cooked four to eight hours with barley miso and burdock
root. It is eaten four days in a row after the birth of the child,
even longer if the mother has difficulty producing plentiful milk.3

The Japanese also eat many other animal foods including beef, pork,
chicken, duck and eel. Beef consumption has climbed in recent years,
some of it locally raised but much of it imported. The famous Kobe
beef is tender and full of fat. The Japanese even import large
quantities of beef offal.4 Consumption of beef liver, tripe and other
organ meats is commonplace. Various organ meats are usually served at
specialty restaurants. Eel served at restaurants is often accompanied
with a soup containing eel innards.

Beef, pork and chicken are usually grilled and served with a sauce
that contains soy sauce along with other ingredients such as merin (a
sweet wine), sake (rice wine), vinegar or sugar.

Soy beans are a distinguishing feature of the Japanese diet,
particularly fermented soy sauce used in most prepared dishes. Almost
without exception, Japanese sauces and marinades are based on soy
sauce. But it would be a mistake to call soy a “staple” in the
Japanese diet, in the way that fish and rice are staples. Dietary
surveys indicate that the Japanese consume an average of about 1/4 cup
of soy products per day, including the ubiquitous soy sauce.5 Other
soy foods include tofu, a precipitated product, and fermented soy
foods such as miso, tempeh and natto. Until recently, these foods were
produced at home or by artisans. They are added in small amounts to
soups or used as seasonings. Natto has such a strong smell that
restaurants serving it have separate natto-eating sections so that non-
natto eaters can be spared the overpowering odor.

Almost all the soybeans used in Japan today are imported and there is
a big demand for organic, non-GMO soybeans.

A typical recipe for homemade miso calls for 5 kg soy beans, a
whopping 3 kg salt and 8 wafers of malted rice (about 1″ by 5″ by 10″
each).6 The beans are cooked, mashed, mixed with the malted rice and
salt and formed into balls. The balls are put into a big bucket lined
with a thick plastic bag. The bag is then closed and a 5 kg weight put
on top. Six months later the miso is ready.

A 1935 recipe for tofu calls for soaking dry soybeans in water for a
day, pounding them with a stone mortar, straining into square molds
and mixing with brine.7 They are then boiled until they become hard
and firm.

The Japanese recognize that soybeans need careful processing to remove
naturally occurring toxins. When they eat beans that are simply
cooked, they use small red ones called azuki. A dish of cooked rice
and red beans is made for festive occasions, such as weddings and
births. Red beans are also used to make sweet cakes.

The Japanese are said to avoid milk products but the statistics prove
otherwise. Average consumption of dairy foods in Japan is about 186
pounds per person per year, more than the total for fish.8 This is
only one-third the amount consumed in the US, but it is not
negligible. Dairy products used in Japan include milk, yoghurt and
butter. Japan has a small dairy industry but also imports milk
products from Australia and New Zealand.

In general, the Japanese do not like sugary desserts. But they enjoy
pounded rice (mochi) covered with sweet bean paste. They also enjoy
mashed sweet potato or chestnuts covered with breading.

Noodles made with wheat flour, egg yolks and salt are an important
feature in the Japanese diet. They may also be made with rice, sweet
potato or buckwheat. Noodles are usually eaten with chicken or duck,
sometimes with lobster and often in broth.

A great variety of vegetables and fruits are sold in the shops and
markets. Favorites include daikon radish, eggplant, bamboo shoots and
many types of mushrooms. Most vegetables are consumed cooked, not raw.
Instead of salads, boiled spinach or watercress is served cold and
seasoned with soy sauce.

The Japanese diet may seem monotonous to Westerners, but the Japanese
actually put a great emphasis on variety. In nutrition classes,
Japanese children are taught to eat thirty different foods a day, and
to aim for 100 different foods a week.9

Making Broth
A fundamental component of the Japanese diet is fish broth, made in a
variety of ways. Japanese chefs take much pride in developing an
individual style with broths. Fish soup made from arajiru, the
discarded portions of the fish such as the head and bones, was
traditionally a common breakfast food. (The meat is deftly removed
from the head with chopsticks, especially the meat behind the eye,
which is extremely rich in vitamin A.) Usually, however, fish stock is
made with dried sardines (niboshi) or dried bonito flakes or powder
(katsuobushi). In the old days, the bonito could be purchased as a
block of dried fish. The block was shaved into flakes with a “shaving
box,” a wooden box with a thin slot lined with a blade. The block of
dried fish was run along the blade and the shavings would fall into a
drawer inside the box. When the desired amount of shavings had been
produced, the drawer was pulled out and the contents dumped into a pot
of boiling water.

Sometimes broken-up chicken bones are added to the stockpot. The broth
is transformed into soup with the addition of vegetables, chicken,
pork, tofu or eggs.

Other nourishing broths are made with dried kelp (kombu) or dried
shiitake mushrooms. The mushrooms are placed in a pot of water and
just before the water comes to a boil, the mushrooms are taken out and
the dried sardines or bonito flakes are added.

Brain Foods
Egg consumption in Japan is higher than in America (40 pounds per
person per year, versus 34 in the US).10 The Japanese consider eggs to
be a brain food. The story is told of a woman whose husband was killed
during the war. She had an infant son and throughout the following
years she gradually sold off all of her furniture to provide her boy
with one egg per day, “so that he could go to college.” The boy grew
up to be an intelligent child and, in fact, did go to college in the
postwar years. Eggs are consumed as omelets, custards and in soups.
They are also an important ingredient in noodles and batters.

Another brain food in the Japanese diet is seaweed, added to soups and
used for wrapping sushi. It is also served as a vegetable. Agar-agar,
a gelatin-like product used extensively in Japan, is derived from
seaweed.

Seaweed provides an abundance of minerals, particularly iodine so
vital for normal thyroid function. Normal thyroid function is, in
turn, vital for normal brain function. It is the presence of adequate
iodine in the traditional Japanese diet that makes it possible for the
Japanese to consume soy products on a daily basis without adverse
effects on the thyroid gland.

Fats and Oils
The Japanese have traditionally used a variety of fats and oils.
Delicious tempura-vegetables and fish dipped in batter and then deep
fried-was cooked in sesame oil, rapeseed oil, whale oil, lard or beef
tallow. That was in the olden days. Today, the Japanese are more
likely to fry in cheap commercial vegetable oils. But even today, lard
is available at the grocery stores in squeezable bottles and skillets
in the better restaurants are greased with beef fat and lard. Use of
shortening and margarine is rare.

Since World War II, the pattern of lipid intake has changed markedly
in Japan. There has been a threefold increase in the intake of
saturated and monounsaturated fatty acids, a reflection of increased
prosperity that has allowed the Japanese to subsist on more than fish
heads and rice. Unfortunately, with the advent of cheap vegetable oils
and processed foods, there has also been an increase in omega-6 fatty
acids along with a lowering of the levels of omega-3 fatty acids. In a
milestone review, published in 1997,11 Japanese investigators blamed
the increase in cancer, heart disease, inflammatory disease such as
asthma and allergies, and even behavioral problems in Japan not on
increases in saturated fat, but on increases in omega-6 vegetables
oils. “Decreasing the n-6/n-3 ratio of foods is recommended for the
suppression of ageing, carcinogenesis and atherosclerosis,” they said.
“This is because n-3 fatty acids suppress but n-6 fatty acids
stimulate ischaemia/inflammation which causes increased free radical
injuries. We suggest that a relative n-3 deficiency as evidenced by
the very high n-6/n-3 ratios of plasma lipids might be affecting the
behavioral patterns of a significant part of the younger generations
in industrialized countries.”

Fermented Foods
Fermented vegetables in the form of pickles are served with all
traditional Japanese meals. They range from pickled cabbage to
eggplant to daikon radish. Pickled foods are an important adjunct to a
diet that includes raw fish because they help protect against
intestinal worms, which can be a frequent problem in Japan. One folk
custom is to consume pickled daikon radish with sushi and sashimi, to
“neutralize toxins.” Daikon radish is one of the best vegetables for
supporting the growth of protective lactobacilli.

A typical recipe for pickling lettuce, cucumber and turnips calls for
sprinkling them with salt and allowing them to stand for about two
days.12 This combination is eaten as a separate course with rice.
Pickled melon is prepared by covering melon slices with sake (rice
wine) and merin (a sweet wine) and sprinkling them with salt. It is
allowed to stand for five days and then eaten as the last course of a
meal.

In the mountainous regions where salt was not available, ingenious
methods for producing pickles evolved. One of these is sunki or
pickled leaves of a type of turnip.13 The leaves are boiled and then
inoculated with zumi, a small wild apple, and fermented for 1-2
months.

An interesting fermented fish product called kusaya comes from the
island of Izu. Mackerel and similar fish are soaked in a brine or
“kusaya gravy” that is used over and over again because salt was a
rare material. After soaking, the fish is dried. In the unused period,
the “gravy” was kept alive by adding just one fish fillet. Kusaya is
distinguished from other dried fish by its strong, unique, peculiar
odor. “If you broil kusaya in your house, the odor will not leave for
three months.”

The typical Japanese dish of sushi originated in funazushi, a type of
round shellfish from Lake Biwa in the Shiga prefecture of Japan. The
shell fish was cleaned, salted, washed and fermented for 4-12 months.
During fermentation, funazushi develops several kinds of organic acids
such as lactic acid, acetic acid, propionic acid and butyric acid, all
of which contribute to its distinctive sour taste and peculiar odor.
The pickled crustacean was sliced and served on rice. In former times,
it was said that if you could enjoy funazushi, you were recognized as
a gourmet. Once an important dish in the area around Lake Biwa, the
catch of the shellfish is decreasing year by year, due to water
pollution, introduced species and shoreline destruction, thus making
funazushi a rare and expensive food.

The main fermented drink in Japan is a rice drink called amazake,
prepared by boiling a block of malted rice until it becomes soft and
drinkable. Salt and sugar are added to taste. In winter, amazake can
be bought from vending machines.

Surprisingly, a fermented milk drink is sold in Japanese vending
machines right next to Coke or Pepsi. Unfortunately, the first
ingredient listed is sugar.

Beverages
All meals in Japan are served with a weak green tea, made with one
teaspoon of tea to six teacups of water. Black tea, coffee and milk
are also common beverages. Milk is available to school children and is
recognized as a healthy food, one that helps Japanese children grow
taller than their ancestors.

The Japanese have interesting ideas about beverages. On a hot day,
most Japanese people, especially older Japanese, prefer hot green tea
to anything cold. They say they want something the same temperature as
their body or that something cold will make them sweat more. In winter
time, they often add ginger to warm drinks as ginger is said to be
warming. Water is avoided as it is said to make one fat!

Beer is a common beverage, and also recognized as one that causes
weight gain. Sumo wrestlers, who can weigh as much as 500 pounds, put
on weight by consuming large quantities of beer, as well as lots of
rice and a nourishing stew called chankonabe.

Factory vs. Traditional Foods
While the Japanese diet is held up as the paradigm of natural eating,
Japan is also home to the world’s quintessential imitation flavor,
MSG. Originally extracted from seaweed, MSG or monosodium glutamate
activates glutamate receptors on the tongue and tricks the body into
thinking it has eaten meat. Today most of the world’s MSG is produced
by Ajinomoto, a Japanese company, through a chemical process. It is no
longer derived from a natural food.MSG is used to make cheap soy
sauces, thus driving out artisanal producers who traditionally took
great care and up to three years to produce the delicious fermented
elixir. Factory-produced soy sauce can be turned out in the space of
three days and contains, besides neurotoxic MSG, many carcinogens.

MSG was used to flavor Japanese rice rations during the war and it is
said that Americans who loved the taste of these rations helped
introduce the flavoring into the US. Today it is found in almost all
processed foods, including those now manufactured in Japan. Yet health-
conscious Japanese recognize the dangers and the more expensive
noodles and processed foods there are labelled “No MSG.”

Many Japanese also recognize the dangers of McDonald’s and other fast
foods that are making inroads in Japan, and they deliberately adhere
to traditional foodways. Some housewives still make all traditional
foods at home, from amazake to miso. Typical of foods still produced
by housewives and artisans are various preparations of the famous
umeboshi plum. The plum trees grow in the region of Mito Ibaraki where
a park is home to 2000 plum trees, attracting three million visitors
per year. Each year thousands of Japanese ladies gather the famous
umeboshi plums to make all sorts of plum delights, including salty
pickled plums. Well-aged pickled umeboshi plums are a great delicacy-
some of them are fermented for as long as 30 years!

Presentation Is Everything
The manner in which food is presented in Japan is always attractive
and distinctive, usually with handsome serving dishes and a great
sense of proportion and harmony. Meals are often served with elaborate
ceremony. On ceremonial occasions and at banquets, a number of bowls
and dishes are set before each guest, so that he may have a wide
choice. Those dishes not partaken of are carefully packed in decorated
boxes and presented to the guest as he leaves.

Even lunch boxes are an art form in Japan, containing beautifully
decorated foods such as large prawns, rice rolled in seaweed, fish and
pieces of fruit. One company in Japan prepares as many as 50,000 of
these lunch boxes per day.14 Many Japanese mothers get up very early
to make lunch boxes containing neatly arranged portions of fish, meat,
rice balls, pickles, and fruit for their children and husbands.

The Japanese Paradox
The Japanese suffered greatly before and during World War II. There
were many food shortages, particularly of fats and animal foods. TB
was common. Many Japanese lived almost entirely on rice during the
war.

It was during the postwar years that the American researcher Ancel
Keys wrote his famous Seven Countries Study in which he included
groups from the Japanese districts of Tanushimaru and Ushibuka. He
noted that the Japanese in these two regions had very low levels of
serum cholesterol, consumed a diet extremely low in saturated fat and
cholesterol and had low rates of coronary heart disease. It was
primarily the Japanese data that allowed Keys and others to conclude
that consumption of saturated fat and cholesterol caused heart
disease.

Keys has been criticized for omitting from his study many areas of the
world where consumption of animal foods is high and deaths from heart
attack are low, including France. This is the so-called French
paradox, one of many. But there is also a Japanese paradox. In 1989,
Japanese scientists returned to the same two districts that Keys had
studied. In “Lessons for Science from the Seven Countries Study,”15
they noted that per capita consumption of rice had declined while
consumption of fats, oils, meats, poultry, dairy products and fruit
had all increased. Between 1958 and 1989, protein intake rose from 11
percent of calories to about 15 percent and fat intake rose from a
scanty 5 percent to over 20 percent. Mean cholesterol levels increased
from 150 in 1958 to 188 in 1989. During the period, mean body mass
gradually increased, with overweight rising from 8 percent to about 13
percent of the population. High blood pressure became more common
while the percentage of smokers decreased from 69 percent in 1958 to
55 percent in 1989.

During the postwar period of improved nutrition the Japanese average
height increased three inches and the age-adjusted death rate from all
causes declined from 17.6 to 7.4 per 1000 per year. Although the rates
of hypertension increased, stroke mortality declined markedly. Deaths
from cancer also went down in spite of the increased use of animal
foods.

The researchers also noted-and here is the paradox-that the rate of
myocardial infarction (heart attack) and sudden death did not change
during this period, in spite of the fact that the Japanese weighed
more, had higher blood pressure and higher cholesterol, and ate more
fat, more beef and more dairy.

Misconceptions
Misconceptions about the state of health in Japan abound. It is true
that the Japanese have lower rates of cancer than the US, although
they are by no means cancer-free. For all types of cancer, the death
rate for Japanese males is 149.8 per thousand versus 163.2 per
thousand in the US. For Japanese females total cancer deaths are 78.1
per thousand versus 109.7 per thousand for the US.16 Japanese have low
rates of lung cancer (even though they smoke far more than Americans)
and low rates of breast, prostate, reproductive, colon and rectal
cancer compared to the US. This is said to be due to the fact that
they consume more soy and less meat, fat and dairy than Americans. But
cancer rates went down in Japan during the period when consumption of
animal foods went up. And the Japanese actually consume far less soy
than Americans because even today, they do not consume much partially
hydrogenated soybean oil. In fact, the most likely explanation for
high levels of breast and prostate cancer in the US compared to Japan
is the high levels of trans fatty acids from partially hydrogenated
soybean oil in American convenience foods.

Fresh fish, rich in vitamin A and omega-3 fatty acids, is one
component of the Japanese diet that protects them against lung cancer.
A study carried out at the Cancer Centre Hospital in Aichik Mapan
looked at the diets of more than 4,000 healthy people and another
1,000 with lung cancer.17 They found that both men and women who ate
large amounts of fresh fish were significantly less likely to develop
lung cancer. A diet that included salted or dried fish in place of
fresh fish did not confer the same protective qualities.

The Japanese do suffer from very high rates of stomach cancer, and
relatively high rates of cancer of the pancreas, liver and esophagus,
the so-called Asian types of cancer. There are many explanations for
this trend, none of them proven. The most common theory is that the
use of highly salted foods such as soy sauce and salted fish is the
cause of stomach cancer. But other dietary components are equally
suspect, including high levels of irritating talc present in white
rice and carcinogens in modern processed soy sauce. A final
explanation is the widespread use of microwave ovens by modernized
Japanese. Japan was the first country to adopt the microwave, which
seemed to many Japanese housewives a safer and more sensible way to
cook food in tiny Japanese kitchens than the old-fashioned gas burner
or stove.18

Japan has many lessons to teach us about the risk of generalization in
scientific studies. All claims about heart disease in Japan should be
viewed with skepticism because the Japanese consider it shameful to
die of heart disease but honorable to die of stroke. Predictably,
deaths reported as due to stroke are much higher than deaths reported
as due to a heart attack.

Japanese women are said to be free of hot flashes but some
investigators believe that hot flashes are “under-reported,” due to
the shyness of Japanese women. Soyfood promotion material states that
“there is no word for hot flashes in Japan” without acknowledging that
there is no word for hot flashes in English either. We use two words
to describe the condition and it is likely that Japanese ladies use
some sort of euphemism.

Another claim is that the Japanese do not suffer from osteoporosis.
But according to a 1998 study carried out by the Tokyo Institute of
Gerontology,19 Japanese women have much higher rates of osteoporosis
than American women-one in three versus one in eleven. Furthermore,
they found that bone mass deterioration begins much earlier in
Japanese women, at age 20 versus age 34 in the US.

According to the statistics, the Japanese have the longest life-span
in the world. Built into those numbers is a very low rate of infant
mortality compared to the US. The Japanese were one of the first
countries to practice widespread birth control and they deliberately
keep their families small. Great care and attention is lavished on
children, starting with the mother’s diet during pregnancy, and
outright poverty in Japan is rare. When the high infant mortality rate
in America is discounted, American men have life-spans equal to
Japanese men and American women have longer life-spans than Japanese
women.20

Stress-Free Living?
In his doctoral thesis about coronary heart disease in Japanese
emigrants, British physician Dr. Michael Marmot also described a
Japanese paradox.21 Dr. Marmot discovered that when the Japanese in
Hawaii maintained their cultural traditions, they were protected
against heart attacks, even though their cholesterol increased as much
as in Japanese emigrants who adopted a Western life-style and who died
from heart attacks almost as often as did native-born Americans. The
most striking aspect of Dr. Marmot’s findings was that emigrants who
became accustomed to the American way of life, but preferred lowfat
Japanese food, had heart disease twice as often as those who
maintained Japanese traditions but preferred high-fat American food.

Dr. Marmot proposed the theory that certain factors in the traditional
Japanese culture protected the Japanese from heart attacks in spite of
a high-fat diet. He noted that the Japanese place great emphasis on
group cohesion, group achievement and social stability. Members of the
stable Japanese society enjoy support from other members of their
society and thus are protected from the “emotional and social stress”
that Marmot believed to be an important cause of heart attacks. The
Japanese traditions of togetherness contrast dramatically with the
typical American emphasis on social and geographic mobility,
individualism and striving ambition, said Dr. Marmot.

But is life less stressful among the traditional Japanese? “Group
cohesion” and “group achievement” can also translate into unrelenting
pressure and stress. Is the traditional Japanese family man, striving
to perform and bring honor to his family, under less pressure than the
westernized Japanese bloke who has decided to chuck it all and hang
out on the beaches? And is the Japanese-American living under
America’s wide open skies, where opportunity abounds, under more
pressure than his relatives in Japan, where opportunities are fewer
and where crowding is commonplace? The Japanese people, including
school children, work long hours, travel miles to school and work and
often have only one day a week free. The pressure on children to do
well in school is intense and the suicide rate among Japanese young
people is among the highest in the world.

What Dr. Marmot’s study really tells us is that increased animal fat
in the Japanese diet protects them from heart disease in spite of
their stressful life-style, not the reverse. High rates of heart
disease among Americans should be blamed on processed foods based on
vegetable oils, not animal fats and a high-stress life style.22

Saturated Fat
Saturated fat from animal sources is said to be the enemy in the
American diet. Researchers espousing this dogma have consistently
ignored evidence that saturated fats actually protect against heart
disease and cancer. The many studies of the Japanese also ignore two
very important sources of saturated fat in their diet.

One of these sources is spam, a canned pork product provided to
American soldiers during the war. Americans may have loved the taste
of Japanese rice rations, but the Japanese loved our rations even
more. Spam provided exactly those dietary components that had been
missing through the years of poverty and privation-animal protein and
fat. In a nation that has been unusually resistant to foreign
influence, spam was quickly embraced and transformed into a popular
snack food. Spam musubi consists of a slice of spam soaked in soy
sauce on top of a bed of rice and wrapped in seaweed-a convenient
morsel resembling sushi. Spam musubi can be purchased in local
convenience stores, including 7-11 stores, in Hawaii. In fact, spam
consumption in Hawaii is higher than the total spam consumption in all
the other 49 states combined due to its popularity among Japanese
Americans.

The other source of saturated fat in the Japanese diet is . . . white
rice, a refined carbohydrate that the body efficiently turns into
saturated fat. As long as the diet is rich in fat-soluble vitamins
from fish and organ meats, and minerals from broth and seaweed, white
rice can be consumed without adverse effects. In fact, for the
Japanese, it is beneficial, providing the substrate for saturated fats
that the diet still lacks. Macrobiotic proponents claim that the
traditional Japanese diet was based on whole brown rice, not refined
white rice. It is said that the first Samurai warriors ate brown rice
while the rest of the nobility ate white rice. Then the samurai slowly
“softened” and started eating white rice. But the true explanation for
the use of white rice may be somewhat different. Brown rice that is
not soaked and fermented, as was done traditionally in India, may
block mineral absorption and cause intestinal problems. The Japanese
prefer the taste and texture of white rice and this preference may
reflect a profound intuition that when rice is consumed on a daily
basis, it should be refined not whole, unless a long and careful
preparation is observed.

The Modern Challenge
The challenge for the Japanese, like the challenge for all countries
in the process of modernization, will be to resist the temptations of
processed foods. But Japan faces an additional challenge and that is
to resist the advice of meddling American health researchers who are
telling them to eliminate vital components of their traditional diets-
beef, pork, lard, tallow and even white rice. Better to pay attention
to a few problematic additives such as talc in rice and impurities in
salt, and to protect artisanal food protection from the cutthroat
policies of the food processing industry.

And one more piece of advice to the Japanese: throw out the
microwave.
