Food myths: Which ones make you crazy?

I have so many items in this category. I think I'll list only my top ten (see next post).

31 Comments:

Animal shortening is evil. Lard is 45% monounsaturated fat, butter is only 21%. I have lots more info – it’s a pet subject of mine. This needs its own thread.
Mayo speeds spoilage. It’s acidic, thus a preservative. Commercial mayo is pasteurized, so even safer.
Beans must be soaked before cooking. Discarding soak water removes a small percentage of gassy agents, but cooking is unaffected.
Never salt beans until they’re cooked. Salting at the beginning results in saltier beans. That’s it.
Pork must be cooked well-done. Math. Trichina die at 137 degrees, medium doneness is 150-155 degrees. Besides, they occur in • Use the pit to prevent avocado browning. Keep oxygen away (plastic wrap on the surface) or add lots of lemon juice. Period.
Salting meat before cooking makes it dry/tough. Brined poultry, salted marinades, etc. Was it dry/tough? ‘Nuff said.
Eating before bed makes you gain weight. Too many calories + too little exercise = weight gain. Timing doesn’t. It’s been proven over and over again.
Milk makes scrambled eggs/omelets tough, watery. Was it Cooks Illus that proved eggs made with water were less fluffy, less soft, less tasty? Use milk. Cream works even better.

Ooops. I accidentally cut off my pork tirade. It's supposed to say:

"...besides, they occur in less than 1% of US pork. If you've never been keen on pork, try it cooked to medium instead of shoe-leather!"

You made me think of the episode of Good Eats where Alton Brown disproves various myths...such as the one about not washing mushrooms because they'll absorb water and get tough. Foolishness...where do people get these things?

-Fat is bad.
(Truth: Our bodies need a certain amount of fat to function properly.)

-Peanuts are bad.
(Only true if you're allergic.)
A woman I used to know who had body image problems once got angry with me for suggesting that peanut butter makes a good afternoon snack. My reasoning: Peanut butter is full of protein, vitamin D, iron, zinc and magnesium. She saw peanut butter as evil, full of fat that will make her fat. This exchange happened in her blog, and her friends vehemently backed her up. I don't recall if I provided links for back up proof but I suspect not.

Not long after that a report was released stating that peanuts act as an appetite suppressant. I felt like throwing that in their faces.

See this link for more healthy peanut facts.

Well, my late ex-mother-in-law believed that eating fish and drinking milk at the same meal would poison the eater, so that was a source of some contention when we visited with our kids.

And I agree with all the above except the salt and cooking beans. It may be the water here, but salt or even tomato products in the bean-cooking water makes them take three or four times longer to cook. I fought this for years, thinking that it was just me. Finally stopped adding the ham bone or anything else to the beans until they were nearly done. (Simmered the bone separately, and reduced the broth while I stripped the meat off the bone; added broth at the "nearly done" spot.)

Most scientific information about food, health and fitness has a half life of around a couple of years, compared with the science of physics where the half life can reach well into many decades. What this means is its very easy to support/disprove information about health food and fitness- which is evident at all the new 'discoveries' that scientists and researcher have been making. But its VERY hard to disprove the effects of gravity for example. So yea, there's a hell of a lot of food myths out there and will continue to grow because people believe a lot of what they hear in the media.
One personal favorite of mine is the whole 'carbs are evil' craze which has really taken off down here in Australia. WHAT THE? We need carbs! Glucose is the main energy source for our brain people!!

I believe the "myth" you criticize about eating before bed is in fact partially true, in that in a sleeping state calories are metabolized much slower (eventually being stored as fat) than at any other time. Even sitting idly for several hours after a meal is healthier.

I always cringe when people insist that MSG is affecting them after eating. Didn't we disprove this a long time ago?

Milk causes phlegm---absolutely false!

My least favorite food myth is that cooking your own meals is more expensive than eating out. I know lots of people here in NYC who believe this, because when you buy groceries for lots of meals at once, you lay out more money than you'd pay for one cheap meal out. Tons of city folks truly believe this, even though it defies logic utterly - I had to explain the math of my weekly food budget to a friend of mine so she'd stop exclaiming about how much money I must have to eat at home all the time.

Also, that old one about how vegetarians are usually listless and weak because it's so hard for them to get enough protein...that one sticks in my craw.

Sear the meat to seal in the juices...AAArrrrghggh. Searing meat carmelizes the sugars in the juices, creating deeper flavor - but juice will still escape.

* Salting meat before cooking makes it dry/tough. Brined poultry, salted marinades, etc. Was it dry/tough? ‘Nuff said.

This is actually true. The act of salting meat by sprinkling salt on raw meat, then storing it, will leach out all the moisture as evidenced by the pool of blood on the bottom of the container. The act of brining is different because the meat is immersed and there is pressure which ...does stuff that Shirley O. Corriher explained on an ep of Good Eats. when he raised the same question.

The use of "myth" to mean "lie" or "misconception" makes me crazy.
But also:
Fat is BAD. (No, we have to have fat in our diets. If we ate no fat, no matter how much protein and carbs we took in, we'd starve to death.)
Leaving the avocado pit in the guacamole because it has "enzymes" which help keep the guac from oxidizing -- already mentioned.
Veganism is healthier than ominvorism. (No, sorry, no evidence to support this. There is evidence to support the notion that diets low in or free from red meat are healthier than diets rich in red meat, but there is no evidence that cutting out animal products altogether provides any health benefits. There is, however, evidence that it makes it a great deal more difficult to get all of the nutrients humans need to survive. If some people choose that diet for ethical reasons, well, ok, they can have fun with it. But there's no evidence that it's healthier.)
Caramelized garlic is bitter. (I hear this frequently at school, but it's just not true. Try it some time, preferably in a dish that is designed for it.)
The French created fine dining and high cuisine. (Crap. There was a tradition in Italy of incredibly elaborate and diverse feasts dating back to centuries before the common era -- you know, the classical Roman period -- while the French still ate mostly with knives and hands until the Renaissance. Not to mention all of the Asian cultures that had highly elaborate cuisines, and probably the Incas and other American empires.)

The myth that meat and dairy form the only good sources of protein, iron, and calcium. My relatives periodically freak out about my not eating chicken or beef, like fish (which I still eat), beans, grains, vegetables, and nuts don't contain any protein.

As far as calcium goes, Marion Nestle put it terrifically. To paraphrase, cows stop drinking milk after they're weaned as babies, yet their skeletons manage to support their 1000-plus pound bodies through adulthood. So are bones dependent on a constant milk supply? Probably not.

Children's Version:

Myth: If you eat all your food you'll grow up big and strong.
Fact: "Like You Daddy?"

Myth: Eating bread crust will make your hair curley.
Fact: I don't know. (I wish I still had hair, straight or curley!)

Myth: There are starving children in Africa who would be happy to eat all the lovely food left on your plate!
Fact: African children are no doubt as fussy as our own. (I wonder what African mothers tell their kids to get them to eat?)

Myth: If you don't finish your dinner you'll get no dessert.
Fact: This may work for some parents, but kids know it will never happen with grandparents.

I'd say it's a myth that any diet is, by necessity, healthier than another. As we have discussed on this board a jillion times, a good vegan or vegetarian diet is healthier than a bad omnivorous diet, while a bad veg diet is worse than a good meat-eating diet. Likewise, it's a myth that vegetarians and vegans can't get adequate nutrition...a much more commonly-held belief than that veganism is healthier than other diets.

On another note, what about the idea that olive oil is bad for cooking? I hear this all the time, due to its purportedly low smoke point. Maybe people who say this just mean deep-frying or something? I sautee with olive oil all the time and "off flavors" never result. Is this a myth?

producestories: in regards to the olive oil like you said, I think people are trying to deep fry with it, which will result in the fatty acid chains breaking down because of the high temperature and giving it a weird taste/look.
You should be fine with the sautee business ^^

Hmmmm, I have a friend who deep fries everything in olive oil, from French fries to tortilla chips. They always taste fine. I've never heard the myth about olive oil before . . . so interesting.

How about the idea that margarine's so much healthier than butter? I know the scientists are split on this one, but personally, I can't see how globs of highly-processed hydrogenated oil prove so much healthier than butter, which is really just shaken milk (obviously, I'm not going to include Frankenbutter in this comparison). In baked goods, especially simple ones dependent on minimal ingredients, you can't beat butter for taste.

My family deep fries everything in olive oil...dunno what the big deal is...always works out fine

Excellent posts!

"Fat is bad" -- Yes, along with "cutting fat is all you have to do to lose weight"
"Fish and milk" -- I remember once being told, 'You can't put parmesan on your linguine and clams... you don't even want to know what it will do to you.' Huh? And what about herring in sourcream?
"Salted beans" -- I've seen recipes that specify bottled water for beans if yours is hard, so maybe that's when it matters?
"Milk and phlegm" -- I'm cracking up... my mom always said that! Great one!!!
"Salting meat: -- Should've been more specific. I meant just before cooking. Many people insist it CANNOT be salted till it's cooked. Hogwash.
"Bread crust" -- Wow. I've never heard THAT one! Too funny.
"Olive oil" -- Seem to remember reading that the best way to deep fry in it is not using extra virgin. Most refined oils have much higher smoke points.

"Eating before bed" -- not to be argumentative, but based on what I've learned over many years in healthcare...

On average, it takes 8-10 hours for food to be metabolized into usable nutrients and energy. It’s highly variable depending on food type, portion size, individual eater, etc., but that's the generally accepted standard. Many medical tests require a 12-14 hour fast to ensure baseline levels of blood sugar, lipids, etc. Athletes typically do their calorie-loading about 5-8 hours before an event, depending on the type of loading (carbs shorter, protein longer). Part of the importance of breakfast is preventing the common afternoon "crash".

The energy powering your body right now has typically been provided by food you ate half a day ago. With few exceptions (e.g., simple sugars), calories consumed now are irrelevant to current activities. The main drawback to eating right before bed is possible sleep disruption (heartburn, discomfort from fullness, etc.). I seem to remember something about it being bad for asthmatics, but I don't remember why.

Most studies indicate no link between meal timing and weight-gain with proper calorie consumption. HOWEVER, people tend to misjudge their calorie intake earlier in the day, and then consume too many calories at dinner or late-night snacking, relative to their overall caloric intake. And we all know if your overall caloric intake exceeds your overall energy expenditure, you will gain weight. But, it doesn't matter whether the calories were consumed at bedtime or breakfast.

In regards to eating before bed: I have an extremely inefficient metabolism. so I just burn and burn energy from food to heat without transferring energy to metabolic needs, which keeps me on the wrong side of thin (don't be jealous, its excruciating) and i find that if I don't have a big meal at least 2 hours before bed then i get hypoglycemia during the night. I'm also along distance runner, so I have high energy needs anyway. Its all matter or individual needs ^^ some people would benefit from eating less at night. I have a big breakfast (after training), a few small snacks during the day and a good sized dinner.

Many of my German friends soldiered their way through childhood and early adulthood without eating sugar snap peas, because they had been told by their parents that raw green beans were poisonous. I'm not sure where the truth lies in this, or why it's a particularly German thing (I've never heard this in the Netherlands or Scandinavia or Britain). Obviously sugar snaps aren't poisonous, but said German friends insist that raw fava beans and raw string beans are. If anyone knows the about this, I'd be interested to hear.

all carbs are fattening- funny how all the people I know who eat low carb have a weight problem.

Remember this oldie...chocolate and fried foods make your face break out! I know...I'm dating myself here!

Pizza was another alleged acne-producer. Also soda, i.e., anything teenagers loved to eat!

JEP - explain why the milk & phlegm myth is incorrect? I'm not being contentious, I'm just curious. It's always been a problem for me ... but then again, I think I'm mildy lactose intolerant.

Kimc54 - you can't be that old; I'm only 20 and I've heard that more times than I can count!

Nothing personal but
Myth: There are starving children in Africa who would be happy to eat all the lovely food left on your plate!
Fact: African children are no doubt as fussy as our own. (I wonder what African mothers tell their kids to get them to eat?)

That offended me. You see, I live in Indonesia and while it might not be as bad as Africa but yes there are starving children here. We're not talking about the rich/well-off kids who could afford to be fussy eater like US kids, but the kids who did not go to school and hit the street to beg, who scrounge around week old trash can to find sthg, ANYTHING to eat, no matter how bad they are. so YES, they would be happy to eat ANYTHING you did not eat. Most people here live poverty, which means not only they can't eat well (well as in nutritious AND hygienic, let's not talk about taste), they can't eat all.

Therefore Indonesian mothers don't really have to tell their kids to 'get them eat'. provide stale rice and salt on the table would make a happy meal.

It pains me beyond belief when someone casually mentions that the food they had were not up to par with their 'foodie' standard and threw them away, after one or two bites. This is nothing personal and I could understand that, but try coming here for a couple of days and see if you could still do the same.

It's stupid I know to get upset of things on the net, but this does me beyond belief.

Again, sorry, nothing personal.

RE: winny: " That offended me. You see, I live in Indonesia and while it might not be as bad as Africa but yes there are starving children here. "

Sorry.

There are obviously starving children, and adults, everywhere, including here in this Country.

The good news is that progress to fight famine and improve nutrition is being made world-wide. Hopefully some day children everywhere will be afforded the luxury of being fussy eaters, much to the chagrin of parents everywhere.

actually i wasn't offended about not mentioning my country, but more of the wasting food thing, ah.. all good now though

Interestingly, dried shelly beans (like kidneys and such) are toxic before cooked....

Pulled this from Wikipedia:

http://en.wikipedia.org/wiki/Kidney_bean#Kidney_bean

"Before they are eaten, the raw bean seeds should be boiled for at least ten minutes to degrade a toxic compound - the lectin phytohaemagglutinin - found in the bean which would otherwise cause severe gastric upset. This compound is present in many varieties (and in some other species of bean), but is especially concentrated in red kidney beans. Although in the case of dry beans the ten minutes required to degrade the toxin is much shorter than the hours required to fully cook the beans themselves, outbreaks of poisoning have been associated with the use of slow cookers whose low cooking temperatures may be unable to degrade the toxin. Sprouts of pulses high in haemaglutins should not be eaten. Red kidney beans, especially, should not be sprouted."

"This is actually true. The act of salting meat by sprinkling salt on raw meat, then storing it, will leach out all the moisture as evidenced by the pool of blood on the bottom of the container"

Uh, Judy Rodgers of Zune Cafe would probably beg to differ-and having had incredible meals at Zune Cafe, I'm a convert of pre-salting meat.

I once read somewhere that a common Japanese superstition is that myoga makes you forgetful. I've never had myoga, can anyone back this claim up?
