Uprooting Top 10 Health Myths
The roots of
International Women's Day began almost 150 years ago on March 8,
1857. On this date, one of the first real organized actions of
women's solidarity took place in New York City. Hundreds of women
staged a strike against the garment and textile factories in New
York City, protesting low wages, long working hours and inhumane
working conditions.
International Women's
Day is a special day reserved to address the issues and needs of
women around the world. In this article we catch up on some Women
health and fitness myths in order to help them better understand
themselves.
Myth #1:
Young women don't have coronary disease.
While
it is true that before the age of
menopause, women without risk
factors (family history,
diabetes,
high cholesterol, for example) do
have an advantage over men in rates of
heart disease. Younger female
patients with classic symptoms are sometimes overlooked even by
their physicians, because of the myth. It is key to know your family
history and the symptoms of heart disease.
Young women
really should be
physically active, watch what they're eating,
reduce
saturated fats in their
diet, eat more fruits and vegetables,
whole grains and good fats, and not smoke. Keep a regular check on
blood pressure and cholesterol levels. It is also important to check
for diabetes if you are
overweight,
obese or have close relatives
with premature coronary heart disease.
Myth #2:
Women should be more concerned about
breast cancer than heart
disease.
A
healthy heart is vital for living life to the full. The majority of
women, over 60 percent, identify breast cancer as their greatest
health concern, yet heart disease and stroke claims more than
eighteen times the number of lives.
Cardiovascular
disease, or heart disease, includes many conditions, but the most
common type is coronary artery disease, which is also the most
preventable. Coronary artery disease involves blockages in the
arteries caused by plaque buildup. If this plaque progresses or
ruptures, heart attack or sudden death can result.
Hypertension,
which is under the umbrella of cardiovascular diseases, can have
many serious effects on the heart, the blood vessels and the kidneys
and, if untreated, is a major cause of stroke. It occurs when the
blood pressure is greater than 140/90 mm Hg. Other types of heart
disease include diseases of the heart rhythm, which can cause either
a very slow heart rate or a fast heart rate. One could also be born
with an abnormal heart, a condition called congenital heart disease.
And heart failure occurs when the heart can't pump properly because
it has been damaged or weakened, or because of high blood pressure
or hypertension.
Myth #3:
Load up on protein for muscle mass
If
the aim is to build
muscle mass, engage in a
strength training
workout and increase
caloric intake by as much as 500 calories . Not
all of these additional calories must come from
protein sources,
especially if the aim of the meal is to replenish what has been
utilized in exercise. About 60 percent of a weightlifting session is
fueled by fats, 35 percent by
carbohydrates, and 5 percent by
protein, according to Essentials of Exercise Physiology.
Consuming more
than 30 percent of food intake as protein may cause a buildup of
ketones, which the kidneys must flush out of the body. This may
stress the kidneys and the heart, lead to dehydration, calcium loss
from the
bones, and a loss of muscle mass. While protein is
essential for building muscle, skin, and hair, synthesizing
hormones, and blood clotting, it is important to remember that even
the most avid athlete benefits most from a balanced diet consisting
of no more than 25 percent fat, 55 percent carbohydrates, and 20
percent protein
Myth #4:
Sweating gets you in shape
The
basic rule of working out is to avoid excessive sweating whenever
possible. Energy is required to cool the system. This energy comes
from the activity of your sweat glands, millions of them lying just
under your skin that use metabolic energy to secrete sweat. This
energy is drained from the total energy you have at your command to
do the work of your body. Your muscles have to share in this energy
in order to function properly. If a disproportionate share of that
energy is used to secrete sweat, then there isn’t enough left for
your other bodily functions. The amount of work you can do lessens
when sweat glands use energy. When exhausted, they stop secreting,
and you are in peril of a heat stroke.
The second loss of energy when you are over-heated is in the
cardiovascular system. When the skin gets hot, the peripheral
vessels leading to the skin open. Blood supply rushes to the surface
of your body. This deprives the muscles of the blood they need. The
heart tries to make up for the loss by pumping harder. The load
becomes so great that if it is maintained for a prolonged period you
could collapse. Inducing sweat is dangerous- and it makes no
contribution to fitness.
Sweating does make the heart work harder, which is an objective of a
fitness workout, but it does so in a hazardous manner. Sweating does
burn calories, but it is a dangerous way to reduce weight.
Myth #5:
Never drink water while exercising
This
is wrong. You shouldn’t even wait until you are thirsty. If you feel
you are losing
water, you should immediately replace it. And if you
intend to exercise the first thing in the morning, you should drink
a glass of water before you start.
The body cells depend on circulation in order to get the energy they
need, and to get rid of their waste products. When you become
dehydrated, the fluids that bathe the cells diminish. The cells
cannot function properly until it is restored. When that happens,
your muscles cannot keep up the work they are doing and your heart
receives an added strain. Part of the fluid you’ve lost is blood
fluid. This means that the heart has to pump that many more times to
re-circulate the diminished supply of blood.
Myth #6:
Women and men can safely drink the same amount of alcohol per day.
The
safe limit for women is one drink a day, fewer than men's two
drinks. Researchers at the Harvard School of Public Health have
found that women who are nondrinkers have a 40 percent lower risk of
getting breast cancer than women who consume two to five
alcoholic
beverages a day. A woman's cumulative lifetime risk is about one in
eight and women who consume more than two drinks a day raise their
risk to one in six. Women who are lighter drinkers (one per day)
have a much smaller added risk and that one drink a day can help
actually reduce the risk of heart disease. A woman should evaluate
her risk factors for breast cancer and heart disease before deciding
about the appropriate level of alcohol in her diet.
Myth #7:
I'll lose
weight if I eat low-fat foods.
This
widespread myth explaining why women are eating less fat yet getting
fatter. National surveys find that despite carving 7 percent of the
fat from our diets, the number of us who are overweight has
increased by 9 percent during the last 14 years. You can put on
pounds even if you eat
low-fat versions of your favorite high-fat
foods. Though you're consuming less fat, you may be eating more
calories. Remember, low-fat doesn't necessarily mean low-calorie.
Low-fat, not
necessarily low-calorie For example, the difference between one-half
cup of vanilla ice cream and one-half cup of low-fat vanilla ice
cream is only about 40 calories. But even if you save calories by
dishing up a 100-calorie, half-cup serving of the low-fat version,
you may be tempted to eat more because it's low-fat and too tasty to
pass up. Eating more equals more calories. By all means,
reduce the
fat in your diet. But if you're watching your weight, remember to
count calories — because calories still count. The average woman
needs between 1600 and 2000 calories a day. You can figure out how
many calories you need each day by multiplying your weight (in
pounds) by 12.
Myth#8:
I had one normal mammogram, so I don't need another one.
One
is not enough. Women should have mammograms done as recommended.
Mammography is the most advanced and cost effective way to detect
early breast cancer. It can detect breast cancer when it is in its
earliest, most treatable stages. However, approximately 15-20
percent of all breast cancers will not be identified by mammography
alone. For this reason, monthly
breast self-examination (BSE) and a
yearly physical exam also are recommended as part of a complete
breast health program.
The American
College of Radiology and the American Cancer Society recommend women
between the ages of 35 and 40 have a baseline mammogram; women
between 40 and 49 should have an annual or biannual mammogram and
should consult their personal physicians about their need for
mammography; and women over 50 should have a mammogram every year.
Myth#9:
Just because headache is common doesn’t mean that it’s normal.
This
is the most significant
headache myth. Despite the out-dated stigma
about people with
migraine or other recurrent headache being
malingerers, weak, neurotic, or having a mental illness, headache is
a real, legitimate, biologic syndrome that can be prevented,
treated, and managed.
Myth#10:
Food eaten late at night is more fattening.
Many
diets tell you not to eat after a certain time in the evening in the
belief that the body will store more fat because it is not burned
off with any activity. However, a study at the Dunn Nutrition Centre
in Cambridge suggests otherwise. Volunteers were placed in a whole
body calorimeter (which measures calories burned and stored) and
were fed with a large lunch and small evening meal for one test
period, then a small lunch and large evening meal during a second
test period. The results revealed the large meal eaten late at night
did not make the body store more fat – it's the total amount eaten
in a 24-hour period that's important, It is true that people who
skip meals during the day, then eat loads in the evening are more
likely to be overweight than those who eat regularly throughout the
day. This may be because eating
regular meals helps people regulate
their appetite and overall food intake.
