8 Food Myths You Need To Stop Believing

You can find healthy eating advice on every corner. That doesn’t mean it’s good advice, though. Nutrition research can be confusing, and it’s always changing. Throw in the sensationalistic headlines and the rate at which information is spread, and it’s no wonder the nutrition tips or suggestions you get from your friend are unsound. Best-case scenario, following bad advice means you unnecessarily avoid your favorite foods. Worst-case, you end up choosing the unhealthier option all while thinking you’re making a better choice.

We zeroed in on eight myths about healthy eating that especially need to die.


Dietary cholesterol has been wrongly accused of raising our blood cholesterol levels for years. It’s become clearer that saturated fats and trans fats are more influential in raising blood cholesterol levels. And while eggs—the yolks included—are high in cholesterol, they are relatively low in saturated fats. Lots of research has been done in recent years, and the verdict is that the entire egg can actually be a part of a healthy diet and in most people, do not significantly impact cholesterol levels or heart disease risk.


Yes, coffee is a diuretic (aka, promotes urine production), but it’s an extremely mild one. It also has a lot of water in it and therefore actually counts toward your daily fluid intake. The amount it would take to dehydrate you is more than anyone should be consuming in a day—if you have two or three cups daily, your fluid levels will be completely fine.


Sugar is sugar is sugar. On a molecular level, the sugar in an apple is the same as the sugar you spoon into your coffee cup. There can be a difference in how our bodies break down the sugar when it’s combined with other nutrients like fiber and protein, but simply being natural doesn’t cut it. Sugar in a whole fruit comes with fiber and helps slow digestion and prevent blood sugar spikes. That’s better than sugar that comes void of other nutrients. But when you squeeze out the juice and drink it, or eat maple syrup, agave syrup, or honey, your body reacts the same way it would to table sugar or the sugar in a Coke.



The word “organic” comes with a big health halo around it, like everything with the label is automatically good for you. The truth is that organic snacks are still snacks. Eating them in excess isn’t suddenly OK because they meet the requirements for an organic label. “Organic chocolate syrup is still chocolate syrup,” Caroline Kaufman, R.D., tells SELF. Organic cookies, crackers, chips, and candies have the same amount of sugar, fat, and empty calories as non-organic versions. When it comes to produce, choosing organic versions of the “dirty dozen”—the foods that typically have the highest amount of pesticides on them—is a good way to cut back on chemical exposure. But Kaufman adds that conventionally grown produce is still safe to eat, since it’s monitored to ensure pesticide residue stays below a certain limit.


Margarine become popular in the fat-is-bad era, but many actually contain trans fats, which are worse for you than the naturally occurring saturated fat in butter. Butter’s ingredient list is short and sweet and doesn’t contain extra ingredients to make up for lack of taste. Not all fake butter is bad, but you have to be cautious about what you’re buying. “I always look at the ingredient list first,” Lori Zanini, R.D., spokesperson for the Association of Nutrition and Dietetics, tells SELF. “Stick margarines are not recommended due to the fact that they contain hydrogenated oils (aka trans fats). Spreads that are in tubs can be considered, just make sure the ingredients are beneficial,” she adds. Look for ones with olive oil to get a good dose of healthy plant-based fat.


You’d think that choosing the salad is safe. But all the add-ons piled atop a bed of lettuce can make the sugar, fat, and calorie count just as high as the mouthwatering burger you’re trying to resist. “Watch out for tricky salad toppings that add up quickly: creamy, bottled dressings; cheese; bacon; croutons; or sweetened, dried fruit,” Zanini says. Other ingredients, like avocado and nuts, are healthy in small amounts but are usually served in too-large portion sizes, Kaufman says. To make sure your salad is as healthy as possible, look for one with leafy greens, lean protein (fried chicken doesn’t count), a small serving of healthy fat, and an oil-based dressing on the side. The oil helps you absorb all the fat-soluble nutrients you’re eating, and keeps you away from caloric creamy dressing.


If you’re still buying low-fat varieties of naturally fatty foods (I’m looking at you, coffee creamer), you might be doing yourself a disservice. “Fat is a necessary part of a healthy diet. You need fat in your diet. Fat is not bad. Fat does not go directly to your hips,” Kaufman reassures. Any extra calories you eat that your body can’t use can be converted into body fat, not just dietary fat. Fat is more densely caloric, though, which is both a blessing and a curse. “Because fat is so rich in calories, it is also very satisfying. That’s good because ideally it means you could mindfully eat or use a small amount to feel full,” says Kaufman. It also means you need to watch your portion sizes. When fat is removed from foods, it’s usually replaced by sugar or salt, so it’s important to read the ingredients list before choosing the adulterated version. Usually, you’re better off eating a small serving of the full-fat kind so you actually enjoy it and feel satiated, Kaufman says.


“Eating gluten free is not necessarily healthier if you do not have Celiac disease or a gluten intolerance/sensitivity,” Zanini says. It’s also important to note that not all gluten-free foods are created equally, or healthfully. “Gluten-free breads and baked goods may still use nutrient-poor, refined flours,” she explains. They can also be high in sugar. If you think you might be sensitive to gluten, or have any of the symptoms of Celiac disease, see an R.D. to ask about being tested. If wheat products don’t make you feel crummy, swearing them off isn’t going to make you a healthier person.

    This article is no better than the “myths” it’s supposedly debunking

    • Avatar Exadyne says:

      This comment is a lot worse than the article it is criticizing.
      All 8 are indeed myths, so please put your scare quotes away.

      • Avatar nonyabizzz says:

        egg yolks are, in fact, not very good for you. The rest are generally correct.

        • Avatar Exadyne says:

          Egg yolks are fine. Whole eggs contain a number of micronutritents, and are a decent source of protein. As the post says, dietary cholesterol is not really associated with lipoprotein levels or cardiovascular risk.

          • Avatar nonyabizzz says:

            There is no dietary requirement for saturated fat. Cholesterol certainly elevates risk. Maybe not if you have a high fat diet anyway. That would be akin to the risk difference between jumping off a 9th floor as opposed to an 11th floor.

          • Avatar Exadyne says:

            There’s no established requirement for saturated fat. There’s also no established requirement for carbohydrates, but that isn’t an argument that people should eat vegetables. There are studies that suggest eliminated saturated fat may negatively impact hormone levels. Admittedly, it is hard to say how much is just the total reduction in fat.
            Saturated fat does have some association with CVD, but in a very, very dose dependent fashion. Again, I could say enough raffinose can poison a person but that isn’t an argument for never eating a single piece of broccoli. Dietary cholesterol’s risk profile is very debated, though definitely downgraded in the general consensus to not of concern in populations that are not at risk.
            The article doesn’t say a diet of nothing but eggs is okay or that one should eat huge amounts.
            I could also argue the studies that actually do show positive benefits for eggs. There are studies showing that eating at least one egg a day is beneficial to testosterone and strength gains in healthy, weight training young men.

          • Avatar Jon Hartley says:

            Everybody has a high fat diet. If you’re getting a very low percentage of your calories from fats, what are you getting them from? Are you chowing down on carbs or are you loading up on hundreds of grams of protein per day?

          • Avatar nonyabizzz says:

            No, everyone doesn’t have a high fat diet. Just most westerners. And the rest of the world is catching up and getting fat. Most all plant foods have at least trace amounts of fat, and there is plenty of protein in plants as well. Whole food, plant based.

          • Avatar Exadyne says:

            It is the increase in all macronutrients that are seeing the world increase in weight, not just fat.

          • Avatar Jon Hartley says:

            Are you under the assumption that fat in foods literally makes you fat? And what percentage are you advocating that people take in from carbs and protein?

          • Avatar Jon Hartley says:

            Westerners who are fat are mostly that way because of excess amounts of sugar. It’s not because they’re eating too much peanut butter or eggs, lol.

          • Avatar Jon Hartley says:

            Sorry for the 8-month necro post, but I rarely check my replies. Again, there are three ways to get calories: protein, carbs, fat.

            If carbs are bad (m’kay) as we’re consistently told, people are either filling up with hundreds upon hundreds of grams of protein each day or getting plenty of fat in their diets. Fat doesn’t literally make you fat…you know that, right?

          • Avatar Bonnie Miller Barber says:

            Too much protein can be a problem. On a high fat diet (KETO) you need to keep the protein to around 20% – too much protein and it’s stored as fat. I live 75% fat, 20% protein, 5% carbs – I’m 110 lbs, 5’2″ – your body harvests the visceral fat and you are seldom hungry. Best way of eating I have ever tried – and I’m a lacto-ovo vegetarian.

          • Avatar WolfmanYX says:

            You are wrong. Our bodies do require saturated fats because that’s what protects our brain cells, joints, cartilage, etc. what our bodies have actual no dietary requirement for is carbohydrates. Our bodies are made of fat and protein, so we need fat and protein to live. We are not made of carbohydrates, therefore they are not a necessary food source. Look up the ketogenic diet and you will be amazed at the lies we’ve grown up with.

          • Avatar nonyabizzz says:

            actually, you are wrong. We need carbohydrates as fuel. All the fats and proteins we need are contained in plants.

          • Avatar Bonnie Miller Barber says:

            No, you’re wrong. We do NOT need carbs when we have enough fat.. You adapt to burn your own fat – healthier without all the visceral fat that people carry around their middle. Check out Dr. Mercola’s Fat as Fuel for the science behind it.

          • Avatar nonyabizzz says:

            Mercola is a huckster.

          • Avatar Pauline Roberts says:

            Wolfman, you are generalising. I have just gone through 3 months on lowering my macro carbs just to see what happened following all the hype. The result was as I expected although I kept an absolute open mind. I was doing protein and fat at 25% each and carbs 50%. I adjusted this to around carbs at 30% with protein and fat at around 35% each although this could vary of course. Within a month I had an even bigger ‘spare tyre’ and even less energy than I already had. I have gone back to what is was and already the spare tyre etc has diminished. What is right for one is not necessarily right for another. The moral here is get to know your own body and what works for you.

          • Avatar Bonnie Miller Barber says:

            Too much protein will get stored as fat. Your macros are way off for a Keto diet. 75% fat, 20% protein and 5% carbs – my blood chemistry improved a ton. I have gotten down to 110 lbs – no visceral fat now, more energy, clearer thinking. You got your macro info from the wrong sources. Check out Fat as Fuel,. Dr. Mercola for the science behind the diet.

          • Avatar Pauline Roberts says:

            Did you not read properly what I put? When I lowered my carbs and highered my fat I went fatter! Not only that, I felt even more sluggish. I have health conditions that when altering my macros it does affect them. I wasn’t doing a Keto diet, I was merely adjusting the macros to see if it had any effect on my spare tyre.

            Interestingly even when I was much younger and actually went a little way below my recommended weight (to the effect of having dizzy spells) I still had a spare tyre. The shape of one’s body has a lot to do with the distribution too. My mother although the same height as me, was longer in the torso and had no flab at all.

            As for Dr Mercola, I certainly wouldn’t credit him for going for advice. Everything is aimed at buying his products. You can’t even look at his website without pop up boxes aimed at selling you his stuff. He isn’t even a proper MD. Since adjusting my carbs back up which I know I need, I have felt much better. As I said, what works for one can be very different for another. Seventy five percent fat may have worked for you and I don’t dispute that. But please don’t go telling everyone else that they should too; this could be dangerous.

            By the way, the source re trying adjusting your macros to see if there is any difference, was here on MFP!

          • Avatar Damo says:

            Dr. Mercola is a known quack.

          • Avatar Bonnie Miller Barber says:

            Best way of eating!! I’ve been eating Keto for almost a year and have never felt better! No grain, no sugar – in any form. I’m a lacto-ovo vegetarian, so it’s not the easiest diet for me, but the benefits are worth the trouble! My doctor agrees – interestingly, his phlebotomist went on the diet based on my health results (blood chemistry). My daily goal is 75% fat, 20% protein and 5% carb. Lots of energy and seldom ‘hungry’ – my memory has actually improved, too!

          • Avatar nbgiant25 says:

            There’s no dietary requirement for gluten or wheat, either, but I’m going to go ahead and guess you don’t have any issues with that intake…

          • Avatar nonyabizzz says:

            If you aren’t celiac, or sensitive to gluten, there is no reason not to eat whole grains

          • Avatar nbgiant25 says:

            That’s not the question. There is no dietary requirement or need to consume them. So there is no reason TO eat them, either.

          • Avatar nonyabizzz says:

            many whole grains contain at least 10% of the RDA of protein and fiber. Some minerals too. Not the only source, but a source.

          • Avatar nbgiant25 says:

            Good for them. That doesn’t make them required, since there are other sources. An individual can avoid them entirely with no negative health impact.

          • Avatar Alberto Liberato says:

            Eggs are nature’s perfect food. Ask any reptile, small mammal or bird. It is their first food of choice. I eat six eggs per day for decades. Cholesterol 145. Triglycerides = 50. That’s not a typo. 50!

          • Avatar Christopher Ryan Seaton says:

            @Alberto how do you cook your eggs?

        • Avatar Jon Hartley says:

          So you have a problem with one of the 8 items on the list and you say the article is no better than the myths? Mind you, your initial post didn’t even include any specific criticism of the article.

  5. Avatar Joseph Piscitelli says:

    I went Gluten Free around 2009, because it was causing Inflammation of my Joints. I have Osteoarthritis. As soon as I looked at the Gluten Free Breads, I was in Shock. Most are like eating a couple of handfuls of Sugar with 37 Grams of Carbs and more. So I just started using Lettuce as my Bread instead.

    • Avatar Shanghaidilly says:

      And I believe that is what the author was getting at. However, I think the author should have added that the biggest problem with people going “Gluten-free” is that most simply want to substitute what they are currently eating with gluten-free versions. This is the wrong way to go about it. I never thought of myself as gluten intolerant, however since my wife is, I went gluten-free 2 1/2 years ago and I have seen health benefits from doing so. But we do what you do, we substitute a lettuce wrap for bread – or simply do without bread of any form, gluten-free or not. We don’t look for gluten-free alternatives, we look for gluten free products that typically unnecessarily add gluten (here’s looking at you soy sauce). And here’s the catch – if you never go gluten-free, you’ll never know whether it is beneficial to you.

    • Avatar Bonnie Miller Barber says:

      Try Smart-Baking Company rolls. I don’t eat grain or sugar (in any form) and their buns are sugar free, starch free, zero carbs – great stuff. (No, I don’t work for them – but I am a big fan.)

  6. Avatar Kaitlin Alexander says:

    The Myth 3 info is not accurate. Not all sugar is the same on the molecular level, the sugar in an apple is not the same as the sugar in your coffee and your body does not react the same way to all sources of sugar. The bit about Coke is especially misleading as HFCS is made up of free, not connected, fructose and glucose molecules and metabolizes differently. “Sugar” is a layman’s term but on the molecular level we are talking about saccharides. There are three monosaccharides: Fructose, Glucose, and Galactose, which are organic chemical structures found in all disaccharides and polysaccharides (aka carbohydrates), including sugar. Most of what we call “sugar” (cane sugar, maple syrup, honey) are disaccharides with varying compositions of two of the monosaccharides, but primarily are made up of varied amounts of fructose and glucose. Each saccharide metabolizes differently in the body and produces different metabolic responses. For instance, glucose signals the release of insulin, while fructose does not. Depending on the monosaccharides that make up sugar, it will require different enzymes (brush order hydrolases such as maltase, sucrase, lactase) to digest and break down into the monosaccharides as only monosaccharides can cross the cell wall. Even then, fructose does not take the same pathway as glucose and galactose. This is basic nutrition science.

    • Avatar Exadyne says:

      Except free fructose and glucose molecules exist in fruits too. The “high” in high fructose corn syrup can mean as little as 5% more than other sources. In order to be digested, all the sucrose bonded together already had to be cleaved in the intestines, it won’d enter the liver as sucrose anyway.
      The point it is making is that the same sugar molecules are the same whether they exist in an apple or in coffee. There absolutely are people that believe there is some difference in a sucrose molecule in a piece of fruit and in a packet of sweetener.

    • Avatar KnowingOneify . says:

      The body processes are sugar the same – this comes from current world renowned physicians from various medical disciplines. Fruit is natures CANDY, it has been genetically modified to be sweeter than the fruit or ancestors ate.

  7. Avatar Food for thought says:

    This article is a disaster starting with Myth #1

    • Avatar Exadyne says:

      Yeah, I know. As someone who makes a living deceiving people about nutrition to get them to buy the latest recycled diet fads, this is a disaster. It means I’ll have to come up with new myths to scare people with in order to sell that won’t work.
      Now, if you’re actually someone looking to improve their health, this article is great.

      I thought the same thing, saturated fat is still labeled as a bad guy for some reason.

      Well hey, feel free to make a broad, sweeping statement without providing substantial evidence to support it.

  8. Avatar thinkfirst says:

    @kaitlin_alexander:disqus You are correc about Myth 3. However, I believe the writer was saying that as long as it is sugar (not HFCS or an artificial sweetener) then it mostly the same. IMHO
    There also seems to be some people here who would like to refute the rest of the myths but don’t even bother to give facts. If you have references to why the rest of these myths are wrong, please submit the links and state your argument. Otherwise, troll somewhere else.

  11. Avatar GiveMeLiberty1787 says:

    Disproven Myth 10: Saturated Fat is bad for you.

    Wrong. Wrong. Wrong. Like dietary cholesterol, recent scientific research is proving more and more that saturated fat IS NOT the cause of poor blood markers. Some of the casual statements made in this article perpetuate this myth created by the sugar industry decades ago. The sooner we get people past the lies our government nutritional overlords have told us the sooner we will no longer be one of the fattest countries on earth.

    There are, though, fats that are absolutely terrible for you. We’re all aware of the dangers of Trans Fats, but the silent killers are the Polyunsaturated Fats found in the junk (very non)vegetable oils that we’re told to cook with and that make up margarine. The inflammatory properties of those fats are doing almost as much damage as grains and sugar.

    Wipe your slates clean, people. It’s time to re-learn nutrition.

  18. Coffee was a major diuretic for me my whole life. Then all the sudden at age 28 it stopped having that effect on me. Does anyone have an idea what changed in my body chemistry to allow for that?

  19. Avatar Ayana Sioux Art says:

    Hahaha this is a terrible article. I never lost weight eating this way. Here’s the truth:

    – Calories in vs. Calories out only works when the count isn’t too low, like 1200.

    – coffee is a stimulant that masks true fatigue. Fatigue needs to be addressed, not ignored by coffee.

    – the study on eggs regarding how it “doesn’t” raise your cholesterol used test subjects with already high cholesterol. Your cholesterol can only get so high. However, the old study on cholesterol and how it can raise your levels was done on someone with normal cholesterol levels and the test subjects levels raised significantly after introducing cholesterol into their diet. Everyone is going crazy over this “new finding” having never read the study and not even realizing that is was conducted horribly. Also many of these studies are funded by food companies and the egg industries themselves.

    – unless eaten in excess quantities, is is impossible for sugar to make you fat. It doesn’t matter where it comes from. Sugar converts to glucose in the body which is used as energy for all the cells in your body. Fat, on the contrary, it’s simply stored as fat unless your body goes through ketosis which is an awful stage to go through. But at that point it’s too much fat and it begins to line your arteries which will lead to a heart attack or stroke.

    – dairy products are horrible products to consume. It is not natural for humans to drink in the first place. Cows milk is made for babies cows, just like cat milk is made for kittens. Would you suck the tit of your cat to get milk and call it healthy?

    None the less, dairy is high in hormones (which are naturally occurring), saturated fat, pus, and ceasin. Thus is why dairy has been linked to cancer such as breast cancer (because dairy is extremely high in animal estrogen) and prostate cancer. It also raises ones risk of heart disease and stroke. It just wreaks havoc on the body.

    This entire article is terrible and full of lies. I’m beginning to think that mfp has a sponcer of some sort, other than the obvious one. Perhaps an egg and dairy company because this isn’t the first time they’ve spread these harmful lies.

  20. Avatar Miranda Penney says:

    I’m glad to see a step away from the usual pseudoscience that is found in “health” articles.

    Although The Dirty Dozen means nothing, organic is a marketing scam at best and uses way more pesticides than conventional farming methods- not that it makes a difference as it is all at safe levels. Avoiding fresh food or opting for a more expensive option b/c it’s on that list is harmful for low income families and in no way affects your “chemical exposure.”

    Also gluten sensitivity is not a thing. I don’t care how much you think it makes you bloated. Celiac is a serious auto-immune disease that can be diagnosed by a healthcare professional.

    Remember: Everything is a chemical, organic is a scam, and don’t drink raw water 😉

    • Avatar James A Tillman says:

      I don’t think organic is a scam especially as it relates to whole fresh vegetables. What you are really trying to avoid is glyphosate found in herbicides like Roundup. This chemical effects your gut microbes essentially killing them. Some of these microbes are critical to health and well being. This chemical also causes leaky gut which allows lectins and bacteria into your body spiking your immune system which leads to many auto immune diseases. This is a known fact which is why a person who became riddled with cancer due to heavy exposure recently sued Monsanto and was awarded a multiple hundred million dollar lawsuit.

    This the worst article I have ever read!!
    No basis on anything and clearly lots of false info!!!!!
    Sugar in your coffee is not the same as sugar in your fruit … your liver runs on glucose turns it into glycogen and feeds your nervous system , heart and brain !!!!!! Glucose from fruit is vital to your health !!! Eggs are horrible for your liver !!! It makes it hard for the liveyr to function and creates fatty liver and thicker blood which in turn affects your cholesterol and heart !!! I will never take info from this page again !!! Horrible how people think they can write on their personal views and. Not on facts !
