Obesity May Trigger Earlier
Puberty for Girls
MONDAY, March 5
(HealthDay News) -- Childhood obesity may lead to earlier onset of
puberty for girls, a U.S. study concludes.
The study of 354
girls from 10 different regions in the United States found that
increased body fat in girls as young as age 3 and large increases in
body fat between the age of 3 and the start of first grade were
associated with earlier puberty, defined as the presence of breast
development by age 9.
"Our finding
that increased body fatness is associated with the earlier onset of
puberty provides additional evidence that growing rates of obesity
among children in this country may be contributing to the trend of
early maturation in girls," study lead author Dr. Joyce Lee, a
pediatric endocrinologist at the University of Michigan, said in a
prepared statement.
Her team
published the findings in the March issue of Pediatrics.
Lee noted that
girls in the United States are entering puberty at younger ages than
they were 30 years ago. Over that same time, there's been a
significant increase in obesity rates among American children.
"Previous
studies had found that girls who have earlier puberty tend to have
higher body mass index (BMI), but it was unclear whether puberty led
to the weight gain or weight gain led to the earlier onset of
puberty. Our study offers evidence that it is the latter," said Lee,
who is also assistant professor in the department of pediatrics and
communicable diseases at the U-M Medical School.
"Beyond
identifying how obesity causes early puberty, it's also important to
determine whether weight control interventions at an early age have
the potential to slow the progression of puberty," she noted.
Is Your Colon Making You
Sick?
by Tamekia Reece
Some experts
claim that routine maintenance of your large intestine can help
stave off serious disease
Like most men,
Ed Bradley, a forty-something Decatur, Georgia, resident, was
somewhat reluctant to get a colonic, a process that cleanses the
colon by irrigating it with water. Yet he had heard of a connection
between poor colon health and disease, especially colon cancer. So
he gave it a try. “If garbage stays in your house, it rots,” he
says. “So why wouldn’t colon ‘garbage’ in your body create
problems?” He believes a colonic (also called colon hydrotherapy or
colon cleaning) helps the body “take out the trash.”
Although health
professionals often dispute the usefulness of colonics, countless
Americans are concerned about their eliminatory health. When Michael
Roizen, MD, and Mehmet Oz, MD, bestselling authors of You: The
Owner’s Manual (HarperCollins) and You: On a Diet (Free Press),
appear on The Oprah Winfrey Show, viewers frequently quiz them on
the indelicate subject of feces and bowel movements, which the
doctors state offer a vital window into our health.
Some holistic
practitioners take this even further, professing, “All disease
begins in the colon.” These providers encourage people to cleanse
their large intestine proactively. But do illnesses really begin in
our bowels? And does the colon really need routine maintenance?
The process of
elimination
The colon, part
of the large intestine, is five to six feet long and connects the
small intestine to the rectum and anus. “Its main job is to take
digested foods [which are liquids], suck out the water and then
package the poop” so you can move your bowels, says Patricia
Raymond, MD, a Chesapeake, Virginia–based gastroenterologist. It
also transports chemicals and toxins ingested through food, water,
medication, air and other sources out of the body.
Eating plenty of
high-fiber foods, like whole grains, fruits and vegetables; drinking
lots of water; and exercising can help keep your colon healthy.
Feces that form an S or C, the shape of the rectum near the anus,
usually mean your colon is operating well, say Drs. Mehmet and Oz.
“Gumball-size pellets” tell you that your colon is temporarily not
functioning optimally, they write in You: The Owner’s Manual.
In addition to
the curvy stools Drs. Mehmet and Oz describe, naturopath Roni Deluz,
RN, ND, PhD, of Martha’s Vineyard, Massachusetts, considers
wholesome those that are four to ten inches long and “golden brown”
in color. If we see “little clumps in the toilet,” we should ask,
“Where’s the rest?” Deluz suggests. Dark, rocky stools should cause
us to question: “Why is it so hard? Where’s the moisture? Where’s
the fiber?” she says. And “a horrible smell like it’s been hanging
around forever,” should spur us to improve our eating habits.
Other signs of
colon health headed downhill include any change in bowel
habits—either going more or less or battling diarrhea or
constipation. While the American Gastroenterological Association (AGA)
defines constipation as more than three days without a bowel
movement, many holistic practitioners believe the bowels should
empty following every meal. “Whatever is typical for you, whether
it’s five times a day or once every three days, any change in that
is concerning,” Dr. Raymond says. Additional warning signs include
frequent indigestion and gas and bloating.
The cause of all
disease?
But health
practitioners disagree on whether the colon is ground zero for a
host of illnesses.
“I don’t know
where that statement came from, but I don’t think there’s any
evidence to say ‘all diseases start in the colon,’?” says Frank
Hamilton, MD, chief of the Digestive Diseases Program Branch of the
National Institutes of Diabetes and Digestive and Kidney Diseases (NIDDK).
Deluz believes a
congested large intestine undermines many other bodily functions and
can even cause colon cancer. “Not having a clean colon contributes
to backup in the entire system. When you can’t clean out your colon,
your liver suffers. If your liver suffers, then your kidneys can
suffer. If your kidneys suffer, then your lymphatic system suffers,”
she says of the body’s other waste-elimination systems. “There’s a
connection [between organs]. That’s why diseases start in the
colon.”
Dr. Hamilton
and Deluz do agree that a healthy colon is important. “If it’s not
functioning properly, it can lead to other disorders of the
gastrointestinal [GI] tract,” Dr. Hamilton says. “For instance, you
can subsequently have out-pouchings within the large bowel, from
longstanding constipation.” Such out-pouchings, called diverticular
disease, can cause bloating, mild cramping and abdominal pain. If
untreated, surgery may be needed. Research has shown an association
between diverticular disease and cancer on the left side of the
colon.
Is cleansing
the colon the answer?
As a substitute
for (or complement to) dietary changes and increased physical
activity, some people turn to holistic approaches, like colonics, to
improve their large intestine’s health.
During a colon
cleansing, “a small tube or speculum is inserted into the rectum and
warm, filtered water is introduced into the colon to start the
release of waste, gas, mucus and undigested food,” says colon
therapist Dorothy Chandler, RN, of Chicago’s Chandler’s Health
Emporium. Practi-tioners believe the procedure eliminates toxic
buildup on the colon wall, reducing the risk of illnesses.
“Cleansing
removes toxicity from the body and allows the colon to have good
muscular contraction,” says Deluz. “Your entire digestive system is
helped, and removing the toxins takes a load off your liver.”
But not all
experts agree with the practice. “When the colon empties, there is
still a thin layer of stool coating it; however, there is no need to
‘steam clean’ it,” says Dr. Raymond. “It’s sort of like plumbing,”
she explains. “You don’t need Drano un--less there is a problem such
as blockage or near blockage.”
Others disagree
or ask where the proof is. “Colonic cleanings have never been done
in a rigorous, scientific manner to evaluate that approach versus
just nutritional intervention,” Dr. Hamilton says. While on Oprah,
Dr. Oz stated that he doesn’t believe colonics are necessary.
Still, “It’s a
good idea to keep your colon healthy because when it’s not happy,
you’re not happy,” Dr. Raymond adds.
Other colon
care options include taking fiber or herbal supplements that claim
to “scrub” or irritate the colon wall to remove hardened mucus and
feces. The AGA believes laxatives “should be taken as a last resort
and only under a doctor’s supervision.” However, Deluz likes the
natural laxative aloe vera, which she says softens impacted stools.
Bradley is
sticking with colonics. “Afterward, your whole body feels lighter,
you feel more awake and aware that you’re managing your health,” he
says. “If this helps even a little to prevent colon cancer and other
problems, I’m all for it.”
PREVENT COLON
CANCER
With a few
lifestyle changes, you can reduce your risk
Colorectal
cancer (cancer of the colon and/or rectum) is the third most common
cancer and second leading cause of cancer deaths among Americans.
The American Cancer Society estimates that colon cancer rates among
African Americans are about 15% higher and deaths about 40% higher
than among whites. No one is certain why. Yet several lifestyle
habits common to black Americans overlap with colon cancer’s risk
factors—being overweight, being physically inactive and eating lots
of fat and red meat and few fruits and vegetables, for instance.
Smoking, a family history and having an inflammatory bowel disease,
such as ulcerative colitis or Crohn’s disease, also increase one’s
probability. To reduce your chances of developing the disease, try
implementing these lifestyle changes.
Eat less fat.
“Diets high in fat, predispose one to colon cancer,” says Edith
Mitchell, MD, clinical professor of medicine and oncology at Kimmel
Cancer Center in Philadelphia. “One should increase the amount of
fresh fruits and vegetables in the diet.”
Eat less meat,
particularly if it’s processed. One American Cancer Society study
found that men who ate three ounces (about the amount in a small
hamburger) of red meat (beef, pork, lamb) daily and women who ate
two ounces were 30% to 40% more likely to develop colon cancer.
Women who ate one ounce (one slice of lunch meat or four slices of
bacon) of processed meats (bacon, sausages, lunch meat) two to three
times per week and men who ate one ounce five to six times per week
were 50% more likely to develop colon cancer than people who ate
less.
Eat more fish
and chicken. Research has shown that diets high in fish and chicken
actually reduce the risk of colon cancer.
Take vitamins.
“There’s been some evidence that increasing vitamin D and calcium
intake can reduce the chance of developing polyps in the colon,” Dr.
Hamilton says.
