Sleepy Surgeons
Scalpels Slip
You might want a good nights sleep if youre headed for surgery, but what
really counts is whether your surgeon is well-rested. Using a virtual-reality
surgery simulator, London researchers found that surgeons who stayed up all night made 20
percent more mistakes and took 14 percent longer to complete surgical tasks. They also
showed more signs of stress and poorer dexterity. Going without sleep impairs performance
as much as a blood alcohol level of 0.10 percent, which itself is enough to have a driver
arrested in many states.

Give us your tired, your poor, and
well probably ruin their health, too
Welcome to Americaits all downhill from here. A 271-page report from
the National Research Council shows that arrival in America marks the beginning of
gradually worsening health for immigrant families. McDonaldization, said one
of the researchers, is not necessarily progress when it comes to nutritious
diets. Recent immigrants eat more fruits, grains, and vegetables, a pattern soon
lost with assimilation. Despite having less access to prenatal care, new immigrants also
have lower rates of infant mortality and low-birth-weight babies than U.S. mothers of
similar ethnic background and social class, presumably due to healthier diets and less use
of tobacco, alcohol, and drugs. The longer they are in America, however, the more they
lose these advantages. Mental health problems, including suicide, also increase as new
immigrants lose touch with family traditions. The good health of new arrivals is found
despite their often being impoverished, or perhaps, in part, because of it.
And ketchup is a vegetable,
too!
Americans are eating 19 percent more vegetables, 22 percent more fruit, and 47
percent more grain products than they did in 1970, according to the October 1, 1998, issue
of Cancer. Thats the good news. The bad news: fully a quarter of our
vegetables are french fries.
The Pharmaceutical Flush
In 1992, German researchers looking for herbicides in water found traces of an
unidentified chemical. Eventually, tests proved it to be the cholesterol-lowering drug
clofibrate, a cousin of the weed-killer 2,4-D. Now so many Europeans are using clofibrate
to lower their cholesterol levelsand excreting it into domestic sewage
linesthat detectable levels are found throughout the entire North Sea, which
receives an estimated 50 to 100 tons of it each year. Researchers are also concerned about
estrogen supplements which are excreted in the urine and can alter sex characteristics of
certain fish at concentrations of just 20 parts per trillion, well below levels triggering
governmental scrutiny.
A Not-So-Healthy Appetite
The National Agricultural Statistics Service of the U.S. Department of Agriculture
reports that the number of animals killed for food in the U.S. hit a new record in 1998,
at 9.4 billion. These included:
| Broiler chickens |
8,470 million |
| Laying hens |
446 million |
| Turkeys |
297 million |
| Pigs |
119 million |
| Cows and calves |
41 million |
| Ducks |
24 million |
Sheep |
5 million |
| Total |
9,402 million |
An estimated 10 percent, or 900 million, of these animals died of
stress, injury, or disease before slaughter. Also reaching new peaks in 1998 were the
amount of animal manure produced (2.6 trillion pounds) and the total combined weight of
human adipose tissue.

Americas collective medical bill will reach $2.1 trillion per year by 2007,
according to the Health Care Financing Administration. The figure is growing at 6.5
percent per year.
Wheres the Beef? Who Cares?
Gardenburger, the nations leading vegetarian burger, is projecting sales
in the neighborhood of $250-300 million in 1999.
Carcinogens Really Are Unhealthy
Eating well-cooked beef or bacon on a regular basis is linked to a
substantial increase in breast cancer risk, says the November 18, 1998, Journal of the
National Cancer Institute, presumably because of the carcinogens that form as meat is
cooked. Apparently the folks at the Breast Cancer Coalition didnt read the report.
On November 20, they were busy lambasting Dr. Bob Arnot for suggesting that dietary
factors can help prevent breast cancer in his book The Breast Cancer Prevention Diet.

breast cancer. J Natl Cancer Inst 1998;90:1724-9.
Americans Arent Buying the
Milk Mustache
Milk consumption continues to tumble, according to the U.S. Department of
Agriculture. From 35.5 gallons per person in 1966, milk consumption fell to 31.6 in 1976,
then to 28.6 in 1986, and 26.2 in 1997. Likely reasons: health considerations, the
availability of juices and bottled water beverages, and aggressive soda marketing.
