49 Health “Facts” You’ve Been Told All Your Life That Are Totally Wrong

MYTH: Eating chocolate gives you acne.

False.

For one month, scientists fed dozens of people candy bars containing 10 times the usual amount of chocolate, and dozens of others fake chocolate bars.

When they counted the zits before and after each diet, there was “no difference” between the two groups. Neither the chocolate nor the fat seemed to have any effect on acne.

MYTH: An apple a day keeps the doctor away.

Apples are packed with vitamin C and fiber, both of which are important to long-term health, but they aren’t all you need.  cool stuff for guys cool stuff to buy cool stuff for kids cool stuff to make

And if certain viruses or bacteria get into your system, an apple will unfortunately do nothing to protect you.  cool stuff for guys cool stuff to buy cool stuff for kids cool stuff to make

Go ahead and get that flu shot, even if you eat apples.

MYTH: Natural sugar like honey is better for you than processed sugar.

A granola bar made with honey instead of high-fructose corn syrup is not better for you.

That’s because sugar in natural products like fruit and synthetic products like candy is the same: “Scientists would be surprised to hear about the ‘clear superiority’ of honey, since there is a near unanimous consensus that the biological effect of high-fructose corn syrup are essentially the same as those of honey,” professor Alan Levinovitz told Business Insider.

The problem is that candy and other related products typically contain more sugar per serving, which means more calories — a difference you should actually be watching out for.  cool stuff for guys cool stuff to buy cool stuff for kids cool stuff to make

MYTH: Coffee stunts your growth.

Most research finds no correlation between caffeine consumption and bone growth in kids.

In adults, researchers have seen that increased caffeine consumption can very slightly limit calcium absorption, but the impact is so small that a tablespoon of milk will more than adequately offset the effects of a cup of coffee.  cool stuff for guys cool stuff to buy cool stuff for kids cool stuff to make

Advertising seems to be largely responsible for this myth: Cereal manufacturer named C.W. Post was trying to market a morning beverage called “Postum” as an alternative to coffee, so he ran ads on the “evils” of Americans’ favorite hot beverage, calling it a “nerve poison” that should never be served to children.  cool stuff for guys cool stuff to buy cool stuff for kids cool stuff to make

MYTH: Eating ice cream will make your cold worse.

If you’re home sick with a cold, you can totally go ahead and comfort yourself with some ice cream.

The idea that dairy increases mucous production is very fortunately not true, according to researchers and a doctor at the Mayo Clinic, who says “in fact, frozen dairy products can soothe a sore throat and provide calories when you otherwise may not eat.”

MYTH: Sugar is as addictive as heroin.

In the 2009 book “Fat Chance,” the author, Dr. Robert Lustig, claims that sugar stimulates the brain’s reward system the same way that tobacco, alcohol, cocaine, and even heroin does, and therefore must be equally addictive. Lustig even cites studies that show parts of our brain that light-up from a sugary reward are the same parts that get excited for many types of enjoyable activities, from drinking alcohol to having sex.  cool stuff for guys cool stuff to buy cool stuff for kids cool stuff to make

The problem, however, with these types of scientific studies of the brain is that “In neuroimaging, there is no clear-cut sign of addiction,” Hisham Ziaudden, an eating behavioral specialist, told Levinovitz.

So, scientists don’t know what addiction in the brain looks like, yet, and until that mystery is solved we should not be living in fear from something as fanciful as sugar addiction.  cool stuff for guys cool stuff to buy cool stuff for kids cool stuff to make
