 Answer To 20 Of Your Biggest Health Questions

Does  olive oil prevent heart disease?
Description: Description: 9EB519C5-8E93-4100-9F18-91D5275D5B10

 Short answer: Yes


The health  benefits of olive oil come from the presence of polyphenols, antioxidants
That reduce the risk of heart  diseases
Polyphenols; flavonoids; antioxidants; health; cardiovascular diseases; cancers; Polyphenols are the most abundant antioxidants in the diet.  
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 have low levels of  polyphenols

Do  cough syrups work?
Description: Description: 8A07AF15-6161-4C9B-BE1C-AC425022B715
Short answer: No

In 2006, the nation’s chest  physicians agreed <http://www.nbcnews.com/id/10777506/ns/health-cold_and_flu/t/doctors-discourage-use-cough-medicine/#.UgqsK2T70Wc>
that  the majority of over-the-counter cough medicines don’t actually work.
These colourful 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? 
Description: Description: 3BBA6900-A397-483E-ADDF-FA054592A8AC
Short answer: Yes

The majority of health  research is stacked against  sugar-sweetened soda <http://www.businessinsider.com/why-soda-is-bad-for-you-2013-5> . 
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?
Description: Description: 6D2458E8-DC99-4189-A01E-17D7C240CDA5
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.
Sunbathers also need to apply a  generous amount  of sunscreen <http://onlinelibrary.wiley.com/doi/10.1111/j.1365-2133.2006..07684..x/abstract%3bjsessionid=5863DBDE73CFD6CC3689B914B9F2B7AB.d04t01>
in  order to get the full benefit of the SPF.
 
Is  the MSG in Chinese likely to give you a headache?
Description: Description: CBA001C8-4B21-4904-9E1B-03579DA72A08
Short answer: No

A  review of 40 years of clinical trials, published in the  journal of the  American Academy of Nurse Practitioners in  2006
<http://onlinelibrary.wiley.com/doi/10.1111/j.1745-7599.2006.00160…….x/abstract> ,
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 1960’s  that seemed to  connect
MSG with a variety of  maladies that people experienced after eating at Chinese restaurants.

Do  nuts make you fat?
Description: Description: 6BD30499-6F2D-42F6-A37E-3B49A509A8C9
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 <http://www.businessinsider.com/calorie-counts-arent-accurate-2013-7>

than  previously thought because
A lot of the fat is excreted from the body.
 
Is  walking as effective as running?
Description: Description: C94EC0C7-2C13-41DD-AD88-FF0A198155D1
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 <http://atvb.ahajournals.org/content/early/2013/04/04/ATVBAHA.112.300878.abstract>  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?
Description: Description: C9E53001-D870-4511-96E6-4833E8D3FA80
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?
Description: Description: BB71CEAD-0ADF-4F2D-AC4A-91BD797383AB
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?
Description: Description: D007083B-F061-4E1E-8AFA-3D54F5AC0260
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.
This is what  reportedly  sickened more than 100 people  at the PlayboyMansion back in 2011.

Does  coffee cause cancer? 
Description: Description: E17E9F8C-9AF1-48F4-8BEB-0D4696874D1E
Short answer: No

Coffee got a bad rap in the  1980’s when a study linked drinking  coffee to pancreatic cancer

<http://www.nytimes.com/1981/03/12/us/study-links-coffee-use-to-pancreas-cancer.html> .
The preliminary report was  later  debunked <http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3063915/> .
More recently,  health studies have swung in favor of the caffeinated beverage.
Coffee  has been linked to a lower risk of type 2  diabetes <http://www.ncbi.nlm.nih.gov/pubmed/20008687> ,

Parkinson’s  disease, liver cancer, and  even suicide.

Do  eggs raise cholesterol levels?
Description: Description: 16E65D31-9B0E-4E9B-9F76-9ABADBFF3560
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

<http://cals.arizona.edu/impacts/2000/cholesterol.html>.

Can  you drink too much water?
Description: Description: ACD11361-0D55-4658-B69E-A6CE48800B75
Short answer: Yes

It is very rare for someone  to die from drinking too much water, but it can happen.
Over-hydrating  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?
Description: Description: 76CED05A-6DE3-40EA-BA77-63DF6F3FED1C
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 <http://www.activia.us.com/> , are  marketed exclusively to treat tummy issues.


Do  whitening toothpastes whiten teeth more than regular  toothpastes?
Description: Description: 173FFD5A-43EE-48ED-A4CC-228BA9F299EC
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?
Description: Description: 79D6A43F-14FB-4100-9DF6-0EECA2F62B0F
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 <http://www.health.harvard.edu/healthbeat/HEALTHbeat_081606.htm> 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?
Description: Description: E3945846-1B1A-453F-A506-7B1369FB2AA5
Short answer: No

Watching TV will not destroy  your rods and cones as the outdated myth suggests. Before the  1950’s, TVs emitted radiation that could increase  an individual’s risk of eye problems

<http://www.utsandiego.com/uniontrib/20050823/news_lz1c23fact.html>

after excessive TV viewing.
Modern TVs have special shielding that blocks these harmful emissions.
 
Is  red wine better for you than white wine?
Description: Description: 4F5DE5F7-A4BA-4427-A4D7-45E0AF122715
Short answer: Yes

Red wine contains much more  resveratrol than white wine, an antioxidant found in the skin of grapes
that has been shown to fight  off diseases associated with aging <http://www.businessinsider.com/health-benefits-of-resveratrol-in-red-wine-2013-3> .
 
Is  bottled water better for you than tap water?
Description: Description: 9D32EAAF-1338-4B4E-B0C3-E8D89415DEC5
Short answer: No

Bottled water is no safer or  purer than tap water, although it is substantially more expensive.
A  recent study by GlasgowUniversity in the U.K. found that bottled water is  actually more likely to be contaminated than water from your  faucet <http://www.businessinsider.com/bottled-water-is-more-dangerous-than-tap-water-2013-1>

because it is less  well-regulated.
Bottled water and tap water typically come from the  same sources — natural springs, lakes, and aquifers.
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.
