The Definitive
Answer To 20 Of Your Biggest Health Questions
Does olive oil
prevent heart disease?
Short answer: Yes
The health benefits of olive oil come from the presence of polyphenols,
antioxidants
That reduce the risk of heart diseases and
cancers.
But to get these healthy compounds, consumers should buy good-quality, fresh
"extra-virgin" olive oil, which has the highest polyphenol content.
Most commercially available olive oils havelow levels of polyphenols associated
with poor harvesting methods, improper storage, and heavy processing.
Do cough syrups
work?
Short answer: No
These colorful
syrups typically contain doses of codeine and dextromethorphan that are too
small to be effective.
Only cough suppressants that contain older antihistamines seem to relieve
coughs.
That includes
brompheniramine, an active ingredient in Dimetapp.
Do sugary soft
drinks lead to diabetes?
Short
answer: Yes
The majority of health research is stacked against sugar-sweetened soda. A large 2004 study in the
Journal of the American Medical Association found that women who drank one or
more sugary drinks per day increased their risk of developing type 2 diabetes
by 83% compared to those who consumed less than one of these beverages per
month.
Do I need
sunscreen with more than 30 SPF?
Short
answer:
No
Sunscreens with an SPF (sun protection factor) of 30 block about 97% of
ultraviolet rays,
While
sunscreens with an SPF of higher than 30 block 97%-98%.
It's
more important that you choose "broad-spectrum" sunscreen, meaning
it protects against both UVB and UVA rays.
Found that all
previous research "failed to identify a consistent relationship between
the consumption of MSG
And the
constellation of symptoms that comprise the syndrome," including
headaches and asthma attacks.
The misconception spawned from several poorly-done small studies in the 1960s
that seemed to connectMSG with a
variety of maladies that people experienced after eating at Chinese
restaurants.
Do
nuts make you fat?
Short
answer: No
As much as 75% of a nut is fat. But eating fat doesn't necessarily make you
fat.
The bigger
factor leading to weight gain is portion-size.
Luckily, nuts
are loaded with healthy fats that keep you full. They're also a good source
of protein and fiber.
One study even found that whole almonds have 20% less calories than
previously thought because
A lot of the
fat is excreted from the body.
Is walking as
effective as running?
Short
answer: Yes
Studies have shown that how long you exercise — and thus how many calories
you burn — is more important
Than how hard
you exercise. Running is a more efficient form of exercise, but not
necessarily better for you.
A six-year study published
in the journal Arteriosclerosis, Thrombosis, and Vascular Biology in April
found that walking at a moderate pace and running produced similar health
benefits, so long as the same amount of energy was expended.
Is drinking
fruit juice as good for you as eating fruit?
Short
answer: No
Calorie for calorie, whole fruit provides more nutritional benefits than
drinking the pure juice of that fruit.
That's because
when you liquefy fruit, stripping away the peel and dumping the pulp, many
ingredients like
Fiber, calcium,
vitamin C, and other antioxidants are lost.
For comparison, a five-ounce glass of orange juice that contains 69 calories
has .3 grams of dietary fiber and 16 milligrams of calcium, whereas an orange
with the same number of calories packs 3.1 grams of fiber and 60 milligrams
of calcium.
Are all wheat
breads better for you than white bread?
Short
answer: No
Not all wheat breads are created equal. Wheat breads that contain all parts
of the grain kernel,
Including the
nutrient-rich germ and fiber-dense bran, must be labeled "whole
grain" or "whole wheat."
Some wheat breads are just white bread with a little bit of caramel coloring
to make the bread appear healthier,
According to
Reader's Digest.
Can a hot tub
make me sick?
Short
answer: Yes
Hot tubs — especially ones in spas, hotels, and gyms — are perfect breeding
grounds for germs.
The water is not hot enough to kill bacteria, but is just the right
temperature to make microbes grow even faster.
Even though hot
tubs are treated with chlorine, the heat causes the disinfectant to break
down faster
than it would
in regular pools.
The most common hot tub infection is pseudomonas folliculitis, which causes
red, itchy bumps.
A more
dangerous side-effect of soaking in a dirty Jacuzzi is a form of pneumonia
known as Legionnaire's disease.
The preliminary
report was later debunked.
More recently, health studies have swung in favor of the caffeinated
beverage.
Do eggs raise
cholesterol levels?
Short
answer: No
Although egg yolks are a major source of cholesterol — a waxy substance that
resembles fat — researchers have learned that saturated fat has more of an
impact on cholesterol in your blood than eating foods that contain
cholesterol.
"Healthy individuals with normal blood cholesterol levels should now
feel free to enjoy foods like eggs in their diet every day," the lead
researcher from a 25-year University of Arizona study on
cholesterol concluded.
Can you drink
too much water?
Short
answer: Yes
It is very rare for someone to die from drinking too much water, but it can
happen.
Overhydrating is most common among elite athletes. Drinking an excess of
water, called water intoxication, dilutes the concentration of sodium in the
blood leading to a condition known as hyponatremia.
The symptoms of
hyponatremia can range from nausea and confusion to seizures and even death
in severe cases.
To avoid this, drink fluids with electrolytes during extreme exercise events.
Can yogurt ease
digestive problems?
Short
answer: Yes
Our digestive tract is filled with microorganisms — some good and some
bad. Yogurt contains beneficial bacteria, generically
called probiotics, that helps maintain a healthy balance.
Probiotics can
relieve several gastrointestinal problems, including constipation and
diarrhea.
Certain
brands of yogurts, like Activa
by Dannon,
are marketed exclusively to treat tummy issues.
Do whitening
toothpastes whiten teeth more than regular toothpastes?
Short
answer: No
Whitening toothpastes usually contain peroxides and other strong abrasives
that might make
your teeth
appear whiter by removing stains. Unlike at-home whitening strips and gels
that contain bleach,
these
toothpastes do not actually change the color of your teeth.
Is
it safe to microwave food in plastic containers?
Short
answer: Yes
But the plastic container should display the words "microwave
safe." This means that the Food and Drug Administration has tested the container to make
sure no chemicals used to make the plastic leech into foods during
microwaving.
If chemicals do
seep out into food, the amounts are tiny and not dangerous to our health.
As a general guideline, plastic grocery bags as well as most plastic tubs
that hold margarine, yogurt, cream cheese,
and condiments
are not microwave safe.
Can watching TV
ruin your eyesight?
Short
answer: No
Watching TV will not destroy your rods and cones as the outdated myth
suggests. Before the 1950s,
Modern TVs have
special shielding that blocks these harmful emissions.
red wine
better for you than white wine?
Short
answer: Yes
Red wine contains much more resveratrol than white wine, an antioxidant found
in the skin of grapes
Is
bottled water better for you than tap water?
Short answer: No
Bottled
water is no safer or purer than tap water, although it is substantially more
expensive.
A recent study by Glasgow University in
the U.K. found that bottled water is actually
While public
water supplies are tested for contaminants every day, makers of bottled water
are only required
to test for
specific contaminants every week, month, or year.
