A small pilot study achieved
big results, reducing symptoms
of coeliac s disease---the auto-
immune disorder that requires a
gluten-free diet---by infecting par-
ticipants with hookworms.
"By the end of the trial, with
worms onboard, the trial subjects
were eating the equivalent of a
medium-sized bowl of spaghetti,
with no ill effects," says Paul Gia-
comin, an immunologist at James
Cook University (JCU) in Australia.
"That s a meal that would usually
trigger a debilitating inflammatory
response, leaving a coeliac patient
suffering symptoms like diarrhoea,
cramps and vomiting."
In the 52-week study, 12 par-
ticipants received hookworms and
although four were withdrawn
from the study for reasons not
pertaining to gluten, or even to
hookworms, the remaining eight
showed a highly increased tolerance
to gluten---and to hookworms.
Over the course of the year,
researchers launched micro-chal-
lenges in which they asked par-
ticipants to eat increasing portions
of pasta and they were able to con-
sume 60 to 75 straws of spaghetti
on a daily basis at the end.
The researchers believe the result
of their study is due to a protein
in the hookworms and aim to cre-
ate a powder version of it, although
the biggest question likely to arise
is whether or not "gluten-free"
will retain its hold after a solution
arrives for coeliac patients.
The study was published in the
Journal of Allergy and Clinical
Gluten-free could be entirely
optional thanks to...worms?
Walking may never become as
trendy as CrossFit, as sexy as mud
runs or as ego-boosting as Ironman
races but for fitness experts who
stress daily movement over work-
outs and an active lifestyle over
weekends of warrior games, walking
is a super star.
For author and scientist Katy Bow-
man, walking is a biological imper-
ative like eating. In her book, Move
Your DNA: Restore Your Health
Through Natural Movement, she sug-
gests there are movement nutrients,
just like dietary nutrients, that the
"Walking is a superfood. It s the
defining movement of a human," said
Bowman, a biomechanist based in
Ventura, California. "It s a lot easier
to get movement than it is to get
Researchers say emerging evidence
suggests that combined physical
activity and inactivity may be more
important for chronic disease risk
than physical activity alone.
"Actively sedentary is a new cat-
egory of people who are fit for one
hour but sitting around the rest of
the day," Bowman said. "You can t
offset ten hours of stillness with one
hour of exercise."
Last year researchers at the Uni-
versity of Texas School of Public
Health asked 218 marathoners and
half marathoners to report their train-
ing and sitting times. Median training
time was 6.5 hours per week. Median
total sitting time was eight to 10.75
hours per day, suggesting that recre-
ational distance runners are simul-
taneously highly sedentary and highly
Leslie Sansone, creator of the Walk
at Home: Mix & Match Walk Blasters
DVD, said too many people believe
that spending gruelling hours at the
gym is the only way to fitness.
"There s this Biggest Loser idea out
there that if you re not throwing up
and crying you re not getting fit," she
said, referring to the popular television
She added that a small study of
non-obese men published in the jour-
nal Medicine & Science in Sports and
Exercise by scientists at Indiana Uni-
versity suggests that three five-minute
walks done throughout three hours
of prolonged sitting reverses the harm-
ful effects of prolonged sitting on
arteries in the legs.
Three miles (five kilometres) per
hour is a good beginning, gradually
working to four miles per hour, she
said about walking.
Dr Carol Ewing Garber, president
of the American College of Sports
Medicine (ACSM), notes that fitness-
walking guidelines of 10,000 steps
per day may be too much for many.
"About 7,500 steps may be more
accurate," she said, adding that current
ACSM recommendations call for at
least 150 minutes of activity each week.
Garber, a professor of movement
sciences at Columbia University in
New York, said research suggests that
even one bout of exercise causes ben-
eficial physiological effects.
But she concedes that walking does
not do everything. It is less beneficial
for bones than running, and for
strength, it is better to lift weights.
"Still," she said, "If you re going to
pick one thing, research says it should
'Walking is the
superfood of fitness'
Scientists suggest that three five-minute walks done throughout three
hours of prolonged sitting reverses the harmful effects of prolonged sitting
on arteries in the legs.
