10 More Food Myths That Just Won't Die

Do vegans struggle to get enough protein? Does skipping meals affect your metabolism? Should pregnant women avoid eating sushi? Are all saturated fats bad for you? Here are ten more food misconceptions that have been thoroughly debunked by nutrition experts.

Last week, we tackled the topic of food myths that refuse to die. Our inbox quickly filled up with follow-up questions from readers, indicating that we had barely scratched the surface of this topic. We asked our nutritionists back to debunk some more common misconceptions about food, health and nutrition that are still widely believed, even though there's overwhelming evidence to the contrary. Here's what they said.

Myth 1: Skipping Meals Affects Your Metabolic Rate

Many of you brought this one up after our last article. You rightfully pointed out that when we debunked the "Don't Eat After X:00pm" myth, we said that skipping a meal will cause the body to enter starvation mode and encourage overeating the next day. We went back to Boston-based nutritionist and wellness counselor Alannah DiBona, who made the initial claim, with your skepticism.

"I love being taken to task," she said, and went on to explain that your suspicions were correct. Skipping a meal does not appreciably change your metabolic rate and it certainly doesn't send your body spinning into a fat-saving "starvation mode". However, that doesn't mean you should skip eating if you're hungry and the clock happens to be have passed an arbitrary time.

When you do, your blood sugar plummets, which results in cravings and increased hunger pangs. When you do sit down to your next meal, your body will send you messages that you're hungrier than you actually are and you're likely to overeat. The best advice? Eat when you're hungry and eat something appropriate for the time of day. If it's 9pm and you're not headed to bed for another three hours, have a light snack instead of going to bed hungry.

As for the so-called "starvation mode"? DiBona notes that it actually takes two-to-three weeks of consistently low caloric intake and at least 24 hours of no caloric intake for your body to compensate with significant metabolic shifts. The United Nations University has an excellent (if not old) paper on the effect of low and no-calorie diets on people of otherwise normal weight that illustrates exactly when the basal metabolic rate begins to trend downward after a dietary change.

Myth 2: Eat A High-Protein Diet To Gain Muscle Mass

You've probably heard the myth that gulping down thick protein shakes and letting meat take over your diet will help you bulk up faster. Not so, says Seattle-based Registered Dietitian Andy Bellatti. He explains, "gaining muscle mass requires two things: weight training that stresses the muscles and consuming extra calories. Eating a high-protein diet that doesn't meet increased caloric needs is not conducive to gaining muscle mass. By simply eating more calories from healthful, whole foods (grains, nuts, seeds, fish, etc.), you will take care of all the necessary nutrients that support muscle growth."

This myth has been circulating for so long — even among bodybuilding circles — that there's an excellent article at Bodybuilding.com explaining that while protein is a needed component in any healthy diet, there's entirely too much emphasis on it when it comes to adding muscle. In fact, the American Dietetic Association and the FDA have specific guidelines for an appropriate diet conducive to resistance training. They suggest limiting your protein intake to no more than 1.7g per kilogram of body weight.

Worse, too much protein in your diet can actually be a bad thing. Alannah DiBona noted that too much protein can stress the digestive system,and the Physicians Committee for Responsible Medicine (PCRM) points out there's research to support the position that super-high-protein diets actually lead to other health problems. While that research isn't conclusive, everyone agrees: a balanced diet — of which protein is a component — that scales with your resistance training is the key to building muscle mass.

Myth 3: Salt Is Bad For You

This myth has its roots in scientific fact. Part of the problem is that salt has been painted as all good and all bad over the years, as both the cause of high blood pressure and heart disease in some cases, and a maligned source of added deliciousness in others. Alannah DiBona explains, "In the 1940s, Duke University researcher Walter Kempner, M.D. famously used salt restriction to treat people with high blood pressure. As the average American diet grew increasingly processed and pre-packaged, excessive levels of sodium became difficult to avoid and salt quickly became demonised."

As with many things, the key with sodium is moderation. The problem with the myth is that it speaks in absolutes. People with hypertension and high blood pressure can and should monitor and limit their salt intake to help control their blood pressure. People with normal blood pressure, on the other hand, have no reason to fear or limit their sodium intake aside from the FDA's daily recommended amount. There's mounting evidence to support the notion that salt isn't all bad.

That said, don't reach for the salt shaker just yet. We said moderation was key and unfortunately most American diets are bereft of moderation. Salt definitely has an impact on the body's ability to regulate blood pressure. Most food prepared in kitchens and restaurants is incredibly over-salted, and the amount of sodium in preserved and processed foods is remarkably high. One 2006 study (PubMed, login required) points out that while normal salt intake may not cause hypertension, the increasing amount of salt in our diets may be a contributing factor, especially among people already at risk.

The National Heart, Lung and Blood Institute at the National Institutes of Health stands by a 1998 statement on the matter advising most people reduce their sodium intake and last year the FDA agreed. If you're worried about your salt intake, DiBona has a suggestion for you: "It's been common scientific knowledge for 20 years that potassium and sodium balance each other; consuming more potassium (in the form of spinach, broccoli, bananas and beans) can have a regulatory effect on blood pressure."

It's a delicate balance. Too little sodium in your diet is unhealthy. Too much sodium in your diet is also unhealthy. A good, moderate amount (at or around the FDA guidelines) is fine. People who already have high blood pressure or are at high risk for hypertension and heart disease should monitor their sodium intake carefully and talk to their doctor about their particular case. Either way, don't be afraid of the salt, just enjoy it sensibly.

Myth 4: Never Freeze Coffee To Store It

Whether or not it's OK to freeze coffee is so hotly debated that there's very little consensus on it, but not for the reasons you might think. Most purists will tell you to never ever freeze coffee, and their intentions are good. We've even tackled the topic before on more than one occasion. Contrary to popular belief, coffee is not a shelf-stable product. The oils on the surface of the beans that give coffee its delicious flavour go rancid very quickly when exposed to light, heat or open air. Coffee beans are also porous, so anything that gets on the surface of the beans may check in and never check out.

The problem with storing your beans in the freezer is that they can absorb odours from other foods, they can grow ice crystals that will damage the beans and impart unwanted flavours and the change in temperature has a negative effect on those delicious oils. The reason most coffee fans will tell you not to freeze coffee is because it's so incredibly difficult to control for these possibilities. They're right, if coffee tasted better and kept longer frozen, you'd buy it in the frozen food section. That said, it may be difficult, but it's not impossible to properly freeze coffee and it shouldn't keep you from freezing coffee if you have a little more than you'll be able to use in a week or two.

First of all, don't grind it — keep it whole bean. Then, make sure you pack it as tightly as you can in an airtight container or bag. Get as much of the air out of it as possible before sealing it up and putting it in the back of the freezer in an opaque container. Only remove it when you're ready to use the whole thing. Don't open the container and subject the coffee to all of those bad influences in the freezer just to get a few beans out. If you do it properly, your coffee can stay good in the freezer for a short while until you're ready to bring it back to room temperature and drink it. Home-Barist.com did a remarkably well-controlled double-blind experiment with experienced coffee tasters and they all were unable to tell the difference between fresh coffee and properly frozen coffee.

The key here though is properly frozen. If you love your coffee, it's probably not a risk worth taking unless you score a huge haul of your favourite bean. If you scoff at coffee snobs and don't really care about subtleties in flavour, it won't matter to you anyway.

Myth 5: Pregnant Women Should Avoid Eating Sushi

This myth comes from the misconception that raw fish and mercury go hand-in-hand. Putting the issue of mercury in fish aside (of which there is an issue, but more on that later) there's nothing in any of the warnings about eating fish during pregnancy that indicates that raw fish specifically is somehow more of a risk than cooked fish. If you're pregnant and love sushi, there's no reason to avoid it unless your favourite sushi involves fish that are generally high in mercury anyway.

Speaking of mercury in fish, yes — current research does suggest that pregnant women avoid fish that are particularly high in mercury during pregnancy. The FDA, the Canadian Food Inspection Agency and the US Department of Agriculture all have a number of published studies on the topic. The FDA also hosts a page outlining the amount of mercury in different fish, updated annually.

If it's parasites or other risks associated with sushi that worry you more than mercury, Andy Bellatti suggests you put your mind at ease. "Fish served in sushi restaurants has been previously flash frozen, which kills parasites as effectively as cooking," he explains. He also points to Steven Shaw's book Asian Dining Rules: Essential Eating Strategies for Eating Out at Japanese, Chinese, Southeast Asian, Korean, and Indian Restaurants, which explains that most fish used for sushi in restaurants around the world are farmed to avoid the problems with parasites in wild fish.

"Fish like tuna are not particularly susceptible to parasites because they dwell in very deep and cold waters. Sushi restaurants typically use farmed salmon to avoid the parasite problems wild salmon have," he explains. The fish that are at times likely to have parasites, like cod or other whitefish, aren't used for sushi anyway and are generally served fully cooked.

Myth 6: Vegetarians And Vegans Don't Get Enough Protein

Protein is protein, regardless of its source and there's nothing to the myth that animal protein is somehow better than plant protein. In fact, all animal protein comes by way of plants somewhere along the food chain. You can get protein from a number of sources other than meat and your body is just as good at absorbing it. Beans, cheese, nuts and even broccoli are all foods high in protein.

"Every single food (except for oils and certain fruits) contains protein. A cup of cooked oats has as much protein as a medium egg," Andy Bellatti explains. "A serving of almonds (23, to be exact) contains the same amount of protein you get in a stick string cheese. Beans are very high in protein. Even spinach, broccoli and potatoes offer protein."

Alannah DiBona concurs. "Most body builders and athletes would probably keel over if they knew the truth: amino acids (the basic building blocks of muscle tissue) are made by plants, not animals. Humans can get these proteins by eating animals, but a properly balanced diet of greens, nuts, fruits, grains and veggies will pack a sufficient amount of protein for muscular development."

The Harvard School of Public Health also supports the point, and explains that it's really the "protein package" that counts, as in the other nutrients and fats that come with the protein that matter. They point out that while a delicious porterhouse is a great source of protein, it's also very fatty. A cup of cooked lentils will deliver the same protein to your plate, with a fraction of the fat (although whether it's as tasty is up for debate!)

Myth 7: Artificial Sweeteners Are 100 Per Cent Safe

This is a tricky myth to tackle, because there's so much active research going on in this department. The important thing to remember is that artificial sweeteners are currently regulated by the US Food and Drug Administration and the FDA classifies them as "GRAS", or "Generally Regarded As Safe". Not very encouraging, is it? It shouldn't be: the FDA will be the first to tell you that the GRAS classification is an industry-applied term, not one the FDA determines through independent testing. Andy Bellatti explains, "Artificial sweeteners are labelled as 'GRAS' by the FDA, but here's the disturbing twist: it is manufacturers that determine that (there is no formal FDA approval process). Some previously 'GRAS' additives, like orange dye #1, ended up being banned due to concerns of their health effects."

He's right: the manufacturers approach the FDA and note that additional research needs to be done, but the components of their sweeteners are all classified as safe, so the sweetener should be as well. Therefore it gets the "GRAS" label, and goes to market unless there's a reason to stop them.

There is good news, however. No organisation that's tested artificial sweeteners to date has found evidence to suggest that artificial sweeteners are linked to illness. The Mayo Clinic does a great job of explaining how artificial sweeteners are made, and suggests some natural sweeteners that impart more flavour, have an equally low glycemic index and can be just as healthy as artificial ones. The Harvard Medical School takes a slightly more conservative approach, and explains that while the American Dietetic Association and the FDA have approved the artificial sweeteners, moderation is key until the matter is fully settled.

Finally, The National Cancer Institute has an excellent page outlining the current state of research into connections between artificial sweeteners and cancer. While some studies have implied there may be a link, nothing is clear and what evidence there is is tenuous at best. 100 per cent safe? No. 100 per cent dangerous? Nope. What should you do? Practice moderation or switch to a natural sweetener. I'm a big fan of agave nectar.

Myth 8: Unsaturated Fats Are Good, Saturated Fats Are Bad

Considering most food labels break the fat content into these two categories, it would be nice if we could say one was good and the other was bad and call it a day. Unfortunately it's just not that easy. The terms "saturated" and "unsaturated" have been co-opted into marketing terms. The truth lies with the type of fat you're eating, where you're getting it, and how much of it you're eating.

"While unsaturated fats like monounsaturated (found in avocados, olive oil, pecans, and almonds) and Omega-3s (found in flax, hemp, chia, seaweed, and fatty fish) are very healthy, a high intake of omega-6 fatty acids (corn, soybean, and cottonseed oils are especially high) is linked with cellular inflammation, which is believed to be a significant factor in the development of many chronic diseases," Andy Bellatti says. Again, it's a lack of moderation that's to blame. "Fast food chains often boast about the use of cooking oils free of trans-fats and low in saturated fat, but the bad news is that the oils they use are generally high in omega-6 oils. Although omega-6 is an essential fatty acid, the typical American consumes an exorbitant amount (the ideal ratio of omega-3 to omega-6 is 1:3, and the average American these days consumes anywhere from 1:20 to 1:25). The saturated fatty acids in coconut and cocoa (either pure unsweetened cocoa powder or chocolates with a cocoa content of 80% or higher) offer many heart-healthy benefits."

The University of Maryland Medical centre has has additional guidelines on the benefits of omega-3s and the issues that arise when the ratio of omega-3s to omega-6 fats are out of balance. For even more reading, the this study by The centre for Genetics, Nutrition and Health (PubMed, login required) goes into deeper detail about the importance of keeping a proper balance, and how badly most western diets are out of that balance.

Myth 9: Lobsters Scream In Pain When Boiled

This one is often conflated with the issue of whether or not lobsters feel pain when boiled, which is another matter entirely. Many people report that when they put a live lobster into a pot of boiling water, they hear noises that sound like tiny screams coming from the pot. One person — likely feeling a little guilty about tossing a live lobster into a pot of boiling water — probably told their friends the poor thing was "screaming", and the myth was born.

In reality, this one is easy to debunk. Lobsters have no vocal chords, no organs of any type for audio communication. It's just not possible for them to "scream" in any way we could hear, in any circumstance. The sound you may hear is expanding air bubbles trapped in their shells expanding and finding an avenue of escape from their bodies while they boil.

Lobsters are invertebrates and have a primitive nervous system. Whether or not they feel pain in the way you or I would if we were injured or burned is debatable, and as none of us will ever be a lobster, it's impossible to know whether the sensory response associated with injury in a lobster is anything like what we would call "pain". A number of recent studies indicate they do feel pain, or at least pain in their own way. After all, every animal has some method of registering dangerous stimuli and responding to it in a way the discourages contact with that stimuli again.

If you love lobster but don't relish the notion of dropping them into a boiling pot of water alive, consider putting them in the freezer first, or splitting their brain in half with a well-placed cut before cooking. Chilling them makes them torpid and sedated and splitting their brain will kill them instantly just before you drop them in the water.

Myth 10: Turkey Makes You Sleepy Because Of Its Tryptophan Content

It's true that turkey is a great source of tryptophan and that tryptophan makes us sleepy. However, turkey isn't the only food that's high in tryptophan. "Chicken, tuna, mushrooms, scallops, shrimp and soybeans contain just as much tryptophan as — and, in some cases, more tryptophan than — turkey," Andy Bellatti says. To boot, after eating, the body diverts blood from other areas of the body to the stomach in order to aid digestion, making us lethargic and warm in the belly. Andy elaborates:

"When the pancreas releases insulin after a meal, blood levels of amino acids decrease — except for tryptophans. So, when amino acids cross the blood-brain barrier, the most abundant one within that pool is tryptophan. Once in the brain, tryptophan stimulates serotonin production, which imparts relaxation and sleepiness.

Here's the catch — the higher our blood sugar levels rise after a meal, the more insulin the pancreas releases (and the more amino acid levels, except for tryptophans, decrease). Simple carbohydrates raise blood sugars more than other foods.

Eating turkey by itself will not impart any sleepiness since turkey is a high-protein, low-carb food (it does not make blood sugar levels rise as much as simple carbohydrates). You'd literally have to eat an entire turkey in one sitting in order for the tryptophan to have an effect.

In essence, it's not just the turkey that makes you sleepy. It's the combination of eating a lot of food and eating a lot of food with high tryptophan content. This one's been debunked so many times that it's surprising it's still around, but it is. The alcohol in that bottle of wine on the dinner table doesn't help matters much either.

This time we wanted to establish a common theme with our myths. Moderation is the key to a good, healthy diet. There are very few absolutes when it comes to food and health, very few things that are all bad or all good. Keep that in mind when you're grocery shopping or re-examining your diet.

Remember, you can debunk your own food myths with a little research and some healthy scepticism about what you read on the internet. As always, these myths just scratch the surface, and we didn't have space for all of the myths that Andy Bellatti and Alannah DiBona submitted. What are some of your favourite food myths that we didn't get to tackle this time around? Share them (and maybe some studies to back up your position) in the comments below.

    Regarding sushi and pregnancy, the risk of Listeria infection should not be overlooked. I suppose it ultimately depends on the freshness and hygiene of where you buy it from, but generally most pregnant women should be avoiding deli/ cold store sections of supermarkets/ shops.

    http://ideas.health.vic.gov.au/diseases/listeria-facts.asp

      +1 to this L.mono is bad, low chance it occuring, but bad

      Agreed - the main reason women are advised not to eat "sushi" (meaning raw fish, but of course not all sushi contains raw fish) during pregnancy is due to the listeria risk, not the mercury content. Listeria risk is low, but consequences devastating for baby, hence the advice to avoid a range of uncooked items unless you've seen it prepared and stored correctly.

        What is interesting is that whereas some countries like the US (and, I presume, Australia) take that very cautious approach, places like Japan consider sushi a healthy meal for pregnant women.

        Also, sushi gets singled out, yet many harmful organisms can grow on food that is stored at incorrect temperatures (Listeria grows when sushi is not refrigerated well). If you eat dairy, meat, chicken, or beans that have been stored at incorrect temperatures, that is also bad news.

        Note, too, that the USDA does *not* list raw fish as an "associated food" with Listeria, but rather smoked fish: http://www.cdc.gov/ncbddd/pregnancy_gateway/infections-listeria.html

          Sushi fish in Japan is sold separately and exclusively for this purpose. It is highly regulated, and has a very short "shelf life" compared to regular 'cooking' fish.

        "Sushi" means sour rice, "Sashimi" is raw, thinly sliced fish.

          Unfortunately, modern society has conflated the two to mean the same thing, rightly or wrongly.

    [Turkey] does not make blood sugar levels rise as much arse simple carbohydrates?

      MC,

      No. Simple carbohydrates affect blood sugar levels more than protein. This is why one good tip for blood sugar control is to have, say, a slice of white bread with something like peanut butter on it (the fat and protein in the peanut butter will help to mitigate the white bread's high glucose-raising effect).

        I believe he was pointing out that it says 'as much arse' instead of 'as much as'. I also found this amusing when I read it in the article.

    Regarding Artificial Sweeteners. . .
    There are three sorts. 950, 951, 952. They are in EVERY food or drink product which uses artificial sweeteners and claim to be sugar free. Like Diet Coke.
    Heres what they mean:

    950, E950: Acesulphane potassium, Acesulphane K
    200 times sweeter than sugar, has a bitter after taste. Used widely as artificial sweetener in low joule gums, drinks, diet foods, etc. Possible carcinogen in humans, caused cancer in test animals. Suggested that it is worse than Aspartame or Saccharin. AVOID IT!

    951, E95: Aspartame
    Artificial sweetener, too many adverse effects possible to list, 92 documented with the US FDA!, Some people are allergic to aspartame, migraine headaches are a common reaction in these people. Research currently in the USA in regard to incidence of brain tumours. Diet drinks containing it are banned for U.S. Airforce pilots and in an pilots magazine, commercial pilots are told to avoid it. In 9,000 products from low joule to pharmaceuticals. AVOID IT!
    See separate article: http://www.mbm.net.au/health/worst_additives.htm

    E952: Cyclamic acid and its Na and Ca salts
    Calcium & sodium cyclamate, artificial sweetener; known to cause migraines and other reactions, can be carcinogenic, caused damage to rats testicles and mouse embryos in tests.
    Banned in the US and UK due its links with cancer. AVOID IT!

    From here: http://www.mbm.net.au/health/900-1520.htm

    Theres also a few more like 954 and 955 which are even worse.

      What about Xylitol? I know it's a natural sweetener, but everyone seems to leave it out when refering to sugar substitutes. Research seems to indicate it's even beneficial for your teeth.

      You have to remember the possible carcinogen list (2B) is a LOT different to the PROBABLE carcinogens list (2A) and it includes a lot of crazy stuff.

      The possible carcinogen list is made up of items that have never had any evidence that it is a carcinogen for human, but it might be possible.

      It includes things like Coffee and Pickled Vegetables.. and I sure aren't giving up coffee and pickles!

      Also it should be noted that artificial sweeteners haver NEVER been found to cause cancer in the many extensive trials used.

      Can't say that site looks at all legit. Youhave any peer reviewed journal articles on the adverse effects of those chemicals?

      Neither of those links works and the base URL does not allow access.

    When there are studies showing significant links between ingested quantities of leucine (which I believe is a rare/low amino acid in the proteins found in plants) and Muscle Protein Synthesis rates and triggers, how could the statements in myth 2 and 6 be true?
    I do agree that the bodybuilding world especially underrates protein from plant sources, but it is provable that some amino acids in proteins are very low in plants and abundant in animal proteins (which are considered "whole" compared to plant proteins), so that would imply that animal proteins are indeed "superior".
    I believe there was also a study where muscle growth occurred at a greater level (though it was a rat study) when rats received egg and whey proteins compared to soy?
    Sorry, don't have the references on hand though; leave that to Mike T. Nelson (Google for website, I won't post a link here).

      Piers,

      Some vegetarian sources of protein (like quinoa and soy) contain all essential amino acids and are considered complete proteins like meats.

      However, the essential amino acid low in beans is high in grains (and the one low in grains is high in beans). As long as vegetarians/vegans eat a varied diet, they have absolutely nothing to worry about re: protein intake or essential amino acid insufficiency. In fact, a vegetarian or vegan can never have a bite of soy and still not have a problem from an amino acid standpoint.

      While fruits, vegetables, and grains are not good sources of leucine, beans, nuts, and seeds are. So, not all plants foods are low in that essential amino acid.

        Thanks for covering this re #6. Exactly the point I was going to make.

        It's not that vegans don't get enough protein per se, but they do have to be careful to make sure their protein intake provides all of the essential amino acids.

        The same goes for essential fatty acids which again require some know-how to make sure the right seeds/pulses are included in the diet to provide these.

        For the rest of us, a bacon and egg sarnie will sort you out.

    As an earlier commenter noted, the risk of raw meats like sushi for pregnant women is bacteria like listeria, not mercury. Listeria can survive freezing, and salt- and vacuum packing. Though the likelihood of picking up the bacteria is probably low in clean and reputable establishments, the severity of an infection (possibility of septicemia, meningitis in an adult and / or miscarriage in an unborn child) means its a risk not worth taking for me, a pregnant woman. PLEASE don't peddle inaccurate information as 'fact' when the consequences of lack of caution can be so devastating.

      Kellie,

      I want to share a response about the Listeria issue by the Alan Henry, the author of this article:

      ""There's a *lot* of concern over the Listeria issue, and in trying to research it, I find tons of mom-blogs and parenting sites that are horrifically afraid, (because frankly, Listeriosis is a horrible disease and pregnant women are more susceptible to it than others) but there are no studies, journal articles, or real independent research that says you should avoid fish or raw fish while pregnant because of it or to reduce your exposure to it. Some people also express concern over deli meats, which is more legitimate because of their processing - same with smoked fish, but not raw fish.

      Here's a little info to the point, and when I brought up the issue to Andy Bellatti after this story was published, he sent me this:
      [www.livestrong.com]

      That said, if any risk is too much, avoid it! Unfortunately, this is one of those things we hear repeated often because the risk may not be worth the reward, and some doctors will warn against it mostly for safety's sake. However, it's worth keeping in mind that people in Japan, Southeast Asia, and the Pacific Rim eat sushi every day, including pregnant women, per doctor's orders. If it were that harmful, there'd be an epidemic of Listeriosis in pregnant women over there."

        "there are no studies, journal articles, or real independent research that says you should avoid fish or raw fish while pregnant"

        That's true - however there's plenty of studies, journal articles and independent research that says Listeria monocytogenes grows on raw fish products at 4 degrees C.

        "If it were that harmful, there’d be an epidemic of Listeriosis in pregnant women over there."

        Nationwide survey of human Listeria monocytogenes infection in Japan.
        A. Okutani, Y. Okada, S. Yamamoto, and S. Igimi
        Epidemiol Infect. 2004 August; 132(4): 769–772.

        "there is an average of 83 cases of listeriosis per year and an incidence of 0·65 cases per million of the population in Japan."

        That's no epidemic, but if you're the 1 in a million that gets it because you read some "expert" on a blog that said he looked up journals and said it was ok....

        Ask any Infectious Diseases doctor and they will advise against eating pre-prepared sushi when you're pregnant. That's standard of care.

        The Benefits do not outweigh the Risks.

          What is interesting is that whereas some countries like the US (and, I presume, Australia) take that very cautious approach, places like Japan consider sushi a healthy meal for pregnant women.

          What is interesting is that sushi gets singled out, yet many harmful organisms can grow on food that is stored at incorrect temperatures. If you eat dairy, meat, chicken, or beans that have been stored at incorrect temperatures, that is also bad news.

            As a PS, the issue of risk is also an interesting one. Almost every medical procedure has some risk of death (we all have to sign those long legal documents!), but doctors aren't accused of dispensing 'dangerous' advice if they, say, recommend someone have a stent put in.

            Similarly, would people consider telling a pregnant woman that she can drive as dangerous advice , since statistically there is a chance she may have an accident?

              Sushi is really bait! Cook your food!

              Interesting comparison, but falls apart when you consider that there is usually an essential reason for most operations. In the case of stenting, yes there's the risk of complications etc. but if the alternative is dying of a heart attack down the line?
              Whereas there isn't any essential reason to eat sushi so negative consequences are comparably worse because not eating it would not lead to negative consequences.

    "it does not make blood sugar levels rise as much arse"

    Regarding the coffee.. It's not a bean it's a seed.

      All beans are seeds.

        then all seeds are beans? Can I ask for some Pumpkin beans?

        Beans are seeds of a certain plant group not all seeds.

    The wording is this article is so awful - particularly the 'protein' myth - caloric stacking does not necessarily induce muscular growth, it does however respond to physical parameters, ie what goes in must come out. So just because you stack calories does not mean you'll gain muscle - but you will gain weight.
    Also "limiting" to just 1.7g per KG per day? do you know how much protein that is? anyone doing more than that is of course not going to see results as it messes with the intestinal tract.

    For instance, A 75KG male (a little on the lower side) is 127.5g a day, which is a significant portion (on top of the carbs you should be taking to maintain a healthy nutrient ratio) to be eating.

    The myth regarding the wholeness of plant proteins also seems a little dubious.

      An increase in calories is absolutely essential for muscle growth. Without additional calories, you really have an uphill battle if gaining muscle mass is the goal.

      Of course, stacking calories alone does not result in muscle gain. That is why my quote mentions that there are *two* things that must happen -- weightlifting exercises that stress the muscles so they grow *and* an increase in caloric intake.

      As far as 1.7 grams of protein per kilogram; it is certainly high. But, I can tell you that in the United States, the average person (not athletes, but the average person) is consuming around 1.1 or 1.2 grams of protein per kilogram of body weight -- without even trying. In the case of bodybuilders, they consume so many calories (ie: 4000 or 5000) that 1.7 grams of protein per kilogram is something they can achieve without even having to think about it.

      I am not sure why you find the debunking of the "plant protein myth" dubious. Is something in particular puzzling you? Not only are some plant foods complete proteins (ie: soy and quinoa), but incomplete proteins are only a concern if someone eats exclusively from one food group (ie: only beans, only grains, only vegetables). The essential amino acid low in grains is plentiful in beans (and vice versa).

      There is no need to have complementary incomplete proteins at the same meal, either -- that has long been debunked. We now know that as long as a vegetarian or vegan eats a variety of foods throughout the day (as almost everyone does!), they get all the essential amino acids the body requires. This is not a "fringe theory" or hypothetical; this is well-established science.

    "Myth 1: Skipping a Single Meal Will Slow Your Metabolism and Force Your Body into “Starvation Mode”"

    I've been following the BodyTrim diet for about 4-6 months now, it's entirely based on eating protein every 3 hours so your body does not go into 'starvation mode' and starts storing fat.

    It works though, I've lost 20kg and it is something I preach to people now, eat every 3 hours so your body keeps burning and not storing.

      So no additional exercise changes or dietary changes. Just eating the same meals but at 3hr intervals?

      That's not exactly how BodyTrim works.

      It's near enough a very low calorie diet (VLCD). The high protein content is mainly there to make you feel full. Beyond that the idea IS to push the body into starvation mode most days so that fat and protein become the principle fuel sources not carbohydrate.

      With only a small supply of carbohydrate, fat will not be deposited and existing adipose tissue will be consumed ( i.e. what happens during starvation). This is a variation of Atkins but the deliberate intention to induce and maintain ketosis remains.

      The jury is still out on whether these very calorie restricted diets cause any long-term damage. But being overweight is definitely is harmful. So if this is working for you, keep going and good luck hitting your target weight.

    While I know it is not the sound of lobsters screaming. I also know that they feel pain, like any animal you need to know something is damaging you, so that you can react to the threat and run away.

    Yes they are also stupid, but seriously when you feel pain do you start screaming the alphabet or doing simple math? I believe even the simplest of creatures experience pain and the awareness of it as much as we do.

    "turkey by itself will not impart any sleepiness since turkey is a high-protein, low-carb food (it does not make blood sugar levels rise as much arse simple carbohydrates). You’d literally have to eat an entire turkey in one sitting in order for the tryptophan to have an effect."

    Read this paragraph, especially the brackets.
