Answer To 20 Of Your Biggest Health Questions #2

11. Does coffee cause cancer?
Short answer: No
Coffee got a bad rap in the 1980s when a studylinked drinking coffee to pancreatic cancer.
The preliminary report was later debunked.
More recently, health studies have swung in favor of the caffeinated beverage.
Coffee has been linked to a lower risk of type 2 diabetes, Parkinson’s disease, liver cancer, and even suicide.
12. 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.
14. 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.
15. 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.
16. 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.
17. 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.
18. 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,
TVs emitted radiation that could increase an individual’s risk of eye problems after excessive TV viewing.
Modern TVs have special shielding that blocks these harmful emissions.
19. Is 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
20. 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
more likely to be contaminated than water from your faucet 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.
