Not everything you put in your mouth is good for you.

There’s a lot of medical information thrown around out there. How are you to know what information you can trust, and what’s just plain old quackery? You can’t rely on your own “google fu”. You can’t count on quality medical advice from Facebook. You need a doctor in your corner.

On each episode of Your Doctor’s Orders, Dr. Terry Simpson will cut through the clutter and noise that always seems to follow the latest medical news. He has the unique perspective of a surgeon who has spent years doing molecular virology research and as a skeptic with academic credentials. He’ll help you develop the critical thinking skills so you can recognize evidence-based medicine, busting myths along the way.

The most common medical myths are often disguised as seemingly harmless “food as medicine”. By offering their own brand of medicine via foods, These hucksters are trying to practice medicine without a license. And though they’ll claim “nutrition is not taught in medical schools”, it turns out that’s a myth too. In fact, there’s an entire medical subspecialty called Culinary Medicine, and Dr. Simpson is certified as a Culinary Medicine Specialist.

Where today's nutritional advice is the realm of hucksters, Dr. Simpson is taking it back to the realm of science.

    Whole Grains Reduce Obesity

    Whole Grains Reduce Obesity

    Whole Grains Reduce ObesityWhile the low-carb world and its extremists will tell you that grains are evil, they are wrong. There is a significant difference between refined and whole grains.
    The differenceWhole grains contain the bran, a fiber-rich outer sheath. Further whole gains have the germ cell and the endosperm. But the refined grain is just the endosperm.
    Compare whole grain bread, which contains substantially more fiber and vitamins than the white bread. Consuming refined grains increases the risk of heart disease. But consuming whole grains decreases risks of heart disease, diabetes, and cancer.
    The BranBran is rich in fiber.  Additionally, bran is a source of B vitamins, iron, copper, zinc, magnesium, and phytochemicals.
    Fiber is EssentialFiber is an “essential nutrient.” An essential nutrient is defined as a nutrient your body cannot make and must get from your diet.
    But carnivore aficionados disagree; they believe fiber is not an essential nutrient. Carnivores note that you really don’t digest fiber. And they opine that people can live without fiber. However, they forget one key, the microbiome.
    The MicrobiomeThe microbiome are the trillions of bacteria, yeast, and fungi that live in your gut.  Many scientists consider the gut microbiota another “organ” of our body.
    There is a clear difference in the type and number of bacteria that occupy the guts of people with obesity compared to those who are not obese.
    Some bacteria will increase hunger hormones. Those same bacteria also decrease satiety hormones, need more food to feel "full." Finally, they increase the ability of fat cells to increase in size, leading to obesity.
    Interesting Functions of Gut BacteriaSynthesize vitamins K and BMake Conjugated Linoleic Acid (CLA) that reduces obesityCLA decreases inflammationIngestion of some fiber promotes the growth of bacteria that decrease the secretion of ghrelin in obese humans.
    In the microbiome, what feeds the bacteria that decrease obesity includes the fiber from whole grains. The bran of whole grains contains powerful fibers like oligosaccharides.
    How much to eat?What is a serving of whole grains? It seems confusing, especially since some products are a mix of both whole and refined grains. In the Mediterranean Diet, you might notice 9 ounces, but is that grain when it is dry or wet or both?
    So it turns out there is a whole grain council that has done the work for you, and they tell you right on the package.
    This makes your math simple. You either need three stickers of the 100% whole grain or six of the other stickers.

    Are Vegetables just BS?

    Are Vegetables just BS?

    Are Vegetables BS?If you have ever seen Paul Saldino, his famous line is that Kale is BS. He even sells the shirt. But are they? Saldino isn't the only one who proposes this.
    Dr. Gundry, a former heart surgeon, has his own take. Gundry claims modern health problems come from eating lectins. Lectins are compounds found in beans that are natural pesticides.  Thus, Gundry claims lectins harm people. Copying destroys lectins.
    Toxins in VegetablesPlants make compounds to protect them against predators - other plants, pests, and the like. But do they harm humans?
    It turns out that some plant defense compounds are beneficial to humans. Take coffee. Yes, coffee - the caffeine is a defense mechanism. Some people will tell you that coffee is bad for you - but they don't get up in the early morning or have kids.
    List of the "Toxins"GlutenPeople who don't have celiac disease or gluten sensitivity do not need gluten-free diets (ref).OxalatesPotassium-rich vegetables such as Brussels sprouts, broccoli, and kale reduce calcium loss and prevent kidney stones from forming. These vegetables are rich in antioxidants that decrease the risk of bladder, prostate, and kidney cancer. Check with your local dietician for a diet based on the type of kidney stone you have. (ref)CaffeineIf you don't drink coffee, you will lose all joy in life. (reference is me)Polyphenols Plant polyphenols have antioxidant, anti-inflammatory, anti-allergic, anti-atherogenic, anti-thrombotic, and anti-mutagenic effects - they are healthy for you (ref)PhytatesConsuming a phytate-rich diet, such as a colorful, plant-based diet, the benefits exceed the impacts on mineral absorption. In addition, phytates are anti-oxidants. (ref)SaponinsThese compounds are among the most well-studied compounds to decrease risk and help treat cardiovascular diseases. (ref)IsothiocyanatesBrassica vegetables contain many valuable metabolites that are effective in chemoprevention of cancer (ref)salicylatesThese anti-inflammatory compounds are the basis of aspirinPhytosterolsphytoestrogen-containing foods, such as legumes, grains, seeds, nuts, fruits, and vegetables, are rich sources of vitamins, minerals, fiber, and other health-promoting phytochemicals.LectinsCooking destroys lectins. Lectin-rich foods, legumes, and whole grains show reduced inflammatory biomarkers in both animals and humans (ref).
    What the literature saysWhat do human trials say about vegetables? They improve health, reduce the risk of heart disease, and reduce the risk of cancer.
    Do some of them contain anti-nutrients? Well, some do bind them, but health benefits outweigh any potential harm.
    Who to believe?You can believe a shirtless salesman of supplements and scams. Someone who was trained as a psychiatrist, who goes into a grocery store shirtless and yells at kale - or you can believe science.
    Fiber as an essential nutrientFiberThe most abundant solid ingredient in breast milk is a fiber. That fiber is human milk...

    The First Vitamin

    The First Vitamin

    The term vitamin was coined by the chemist Casimir Funk as he revealed the Thiamine structure to the world. So while you may think – isn’t vitamin A (it is the alphabet) the first vitamin – we take our poetic license here to point out that the first compound to be called a vitamin was Thiamine, now known as vitamin B1. But the story of that vitamin was made possible by two individuals – but the most noteworthy was Takaki Kanehiro.
    Our podcast today discusses the education of Kanehiro and how that influenced his view. But let’s work backward a bit.
    Vitamin B1 and Beriberi
    Beriberi is caused by a lack of vitamin B1 (thiamin) in the diet. This vitamin is essential in the biochemical process of utilizing fats, carbohydrates, and proteins for energy. The nerves are particularly affected because of their metabolic pathways – hence, a wide range of symptoms from difficulty with walking (motor function) then sensory function of the legs, and finally, it affects the conduction in the heart, which leads to death.
    White Rice and Beriberi
    White polished rice was the fad food not only in the cities of Japan but also in China. To polish the rice, the husk and germ are removed, but this is also where the vitamins are. When people eat just one food item, they are likely to develop a deficiency disease, and this was the case with sailors and white polished rice.
    The officers would not only eat rice but were given a variety of foods and thus avoided beriberi. But the crew typically only ate white rice.
    Beriberi in Mid-1800’s Japan
    In Japan in the mid-1800s, especially in the city, polished white rice was the calorie source of choice. White rice is easy to store, looks clean, is faster to cook, and eating it is less chewy. White rice was considered what the wealthy people ate – it was beautifully displayed, and unlike brown rice, did not go rancid. What they didn’t know was the processing of the rice led to stripping the rice of the vitamin-rich portion. 
    In the rural areas of Japan, there was little beriberi as they mostly ate brown rice (barley rice). 
    This led to a major problem in their Navy, where beriberi was endemic. White polished rice was the caloric source for the Navy, and often one third of the crew would develop beriberi and be unable to carry out their duties.
    There were many thoughts as to the cause of beriberi, but none of them had panned out well.
    Eastern Traditional Cures for Beriberi
    On occasion, Eastern healers would recommend various teas and herbs. But, some would recommend barley rice. Some of these cures are retrospective, meaning once the traditional Japanese medical folks learned that barley rice was a cure for beriberi, they stated that they had prescribed it for years. Barley rice does have vitamin B1 (1 cup contains a day’s supply). But during the time, the cures from these village doctors were rare and not enough for the Japanese Navy, in spite of losing more people to beriberi than to war – would adopt. Also, note that barley rice is not as transportable as white polished rice and has a shorter shelf life. During this time, Japan was becoming westernized, and they were working on importing medical ideas from Germany, although they had a fair bit of influence from the British method. 
    Kanehiro’s training
    When Kanehiro was being trained, his initial training was from the Eastern Medicine part of his province. This training was apprentice-like, and he heard someone say that “There are no good doctors in Sustama.” When William Wills opened a medical school in his province, he jumped at the chance – but Wills encouraged him to go to London for further training.
    In order to do this, Kanehiro joined the Navy in 1872. He remained in the Japanese Navy for the rest of his...

    The Green Mediterranean Diet

    The Green Mediterranean Diet

    The Green Mediterranean DietImagine being able to improve the Mediterranean Diet with a few changes. Is the new "Green" Mediterranean Diet the ultimate hack? The Green Mediterranean Diet  (Green-Med) has become the hottest version of the MED diet yet.
    Advantages of the Green Mediterranean DietThere are three advantages to Green-Med
    Less Fatty LiverDecreased risk of heart diseaseLess Visceral Fat
    Fatty LiverNon-alcoholic fatty liver disease is the number one cause of liver failure in the United States. It surpassed alcoholic liver disease as the number one reason for liver transplants. But how do you get fatty liver?
    Is fatty liver caused by sugar or fat or both?Low-Carb enthusiasts blame fructose, or almost any sugar, as the cause of fatty liver disease. Although the latest boogyman is "seed oils." On the other hand, vegans will blame saturated fats.
    But sugars in mice are not the same as sugars in men.
    Fatty liver appears to be a byproduct of obesity, excess calories, and genetics.
    Reducing fatty liverAfter weight loss surgery, people rapidly lose weight, including in their liver.
    But people on the Green Mediterranean Diet lost more weight in their liver than those with the standard Mediterranean diet.
    Visceral FatBelly fat is one of the hardest fats to get rid of. As people age, belly fat increases. So when women go through menopause, they increase belly fat.  And lowering belly fat is best done through weight loss with a high-fiber diet and cardiovascular exercise. But Green-Med appears to lower it even more.
    Cardiovascular Risk FactorsAlthough MED is known for reducing the risk of heart disease, Green-Med seems superior.
    Implementing the green Mediterranean DietThe difference between the green and standard Mediterranean diet
    28 grams of walnuts a day - about one ounce3-4 cups of green tea per day100 grams per day of frozen MankaiReduction in red meat
    Green Tea is Easy
    There are more polyphenols in it than in black tea - so it's easier to drink.
    Adding walnuts is easy; they are also a great source of omega-3 fatty acids.
    Decreasing red meat isn't difficult.
    Finding Mankai or duckweed - well, you can't in the United States
    No one has reproduced the data about the Green Mediterranean Diet - perhaps because they can't find those frozen cubes of duckweed.

    LiverKing Falls From Grace

    LiverKing Falls From Grace

    LiverKing Falls From Grace
    Not that anyone was surprised the so-called Liverking was using steroids. But he fooled many people that his diet and intense training led to this frame. The diet he recommended was some form of an "ancestral" diet. We have covered the carnivore-type diet before. So how did this all happen?
    The Rise of LiverKingLiverKing's rise was meteoric. He began posting on Instagram in 2021 and now has almost 2 million followers.
    His trademark was showing off his abdominal muscles on his five-foot-five-inch frame. All the time advocating eating raw liver.
    Isn't that a hook? Eat raw liver, get abdominal muscles, and look like him.
    But his rise was anything but an accident.
    Powering up the MediaIn his emails, he whines about how he wants to build his following but was concerned that the steroids he had were not enough. So he was begging for help from someone in the UK. He was taking thousands of dollars of steroids a month.
    His plan? Getting over a million followers and selling supplements.
    He had a "live-in" video recorder to follow his antics.
    Guess who his partner was in supplements?
    The Supplement IndustryHow do most scam artists in the medical field make money? Selling supplements. Be that Joseph Mercola, or Mark Hyman, or Ken Berry. All people who make millions a year selling supplements.
    So what to do if you are trained in psychiatry but don't want to see people? You sell supplements. So the business partner is one Dr. Paul Saldino - aka Carnivore MD.
    Since the revelation about Brian Johnson's (LiverKing) steroid use Saldino said he would have to distance himself from him. Good friend, eh? That is a business decision. If you are a friend of mine and have a fall from grace, I will be at your door to help, not distance.
    This was pure theater and pure business - well, not so pure.
    Supplements can kill.
    But so can their diet.
    The Diet They Don't EatMake a following eating raw liver. Yell at the dinner table about how raw liver is good for you. Makes great content for your videos. Eating raw liver can kill you.
    Carnivores and extreme keto types always like pointing to hunter-gatherer societies for optimal "primal health." But my cousins in Alaska don't eat liver.
    There is enough vitamin A in polar bear's liver to kill 52 people. But the biggest outbreak of trichinellosis in the United States came from eating grizzly bear liver.
    Wait, can I get sick from too much Vitamin A?Vitamin A toxicity symptoms include drowsiness, irritability, abdominal pain, nausea, and vomiting. Then you lose your hair; then your skin starts to peel. Not to mention it can damage your liver - ironic, eh?
    The tolerable limit of vitamin A is 10,000 units a day. Beef liver has 15,000 units in 3 ounces.
    But LiverKing didn't eat liver in real life. What did he eat?
    The Maple Syrup and Hormone DietLiverKing ate 120 grams of maple syrup, 50 grams of dextrose, and ONLY 2 ounces of red meat a day.
    Why - he was taking insulin and needed to take a lot of sugar.
    He said he was super strict, working out - and his emails had his diet. Almost none of it was organ meat. He was specific and precise.

    Leaky Gut: Facts and Fads

    Leaky Gut: Facts and Fads

    Leaky Gut: Facts and FadsThe latest fad of supplement makers is to talk about "gut health." The latest boogyman for the gut is the "leaky gut." The other name for leaky gut is intestinal permeability.
    A Surgeon's ViewAs a surgeon, a "leaky gut" is a devastating surgical emergency. Surgeons emergently operate to remove the gut that no longer has a barrier function.
    The dark gut is dead and needs to be surgically removed. This gut has no barrier function and will allow bacteria from the inside of the small bowel to easily enter the patient's bloodstream. Leading to septic shock and death.
    The Non-Surgical Emergency or Chronic Leaky GutBut a leaky gut doesn't have to be so dramatic.  Not leading to septic shock or needing to be removed. In this model, the intestinal barrier is "leaky," not to the point of causing sepsis. But the leaky gut enables small molecules to leak out of the gut into the bloodstream. Thus producing chronic inflammation.
    Chronic inflammation may cause obesity. Emphasis on "may."
    Emulsifiers and ObesityRodent studies have provided fascinating insights. Certain emulsifiers, when added to the diet of mice or rats, lead to obesity.  In one experiment, rodents were fed identical amounts of kibble. But one group, emulsifiers, was added to their water.  These emulsifiers, like polysorbate 80, not only produced obesity but also disrupted the microbiome of the gut (ref). But mice are not men.
    When dietary emulsifiers are examined in humans, high levels cause disruption of the gut. However, there is little evidence that small amounts found in the food supply cause issues. (ref 4)
    Non-Humans and Leaky GutWhile animal models are interesting, human studies provide useful information. That a rat or mouse has a leaky gut based on some intervention is not an equivalence in humans.
    Functional Medicine and Leaky GutIf you searched "leaky gut," you will find a host of "functional medicine" doctors providing supplements, bone broth, probiotics, and other scams.  On the shelves of drug stores and "health food stores," you will find abundant supplements to "support gut health."
    Disease States and Leaky GutFunctional medicine physicians associate many disease states with leaky gut. The following have little or no good evidence to be caused by a leaky gut:
    Alcoholic cirrhosisAsthmaAutismChronic fatigue syndromeDepressionEczemaEnvironmental enteropathyEosinophilic esophagitisFibromyalgiaKwashiorkorMetabolic syndromeMultiple sclerosisNon-alcoholic fatty liver disease (NAFLD)ObesityPancreatitisParkinson's diseasePsoriasisRheumatoid arthritis
    Non-Controversial Causes of Leaky GutThere is no doubt celiac disease, Crohn's disease, radiation, and ulcers from non-steroidal anti-inflammatory drugs; certain bacteria can cause a change in intestinal permeability (another name for leaky gut). Celiac disease and Crohn's disease have been studied for years (ref 2, ref 3). While we know gluten exacerbates the auto-immune function of those with Celiac disease, we do not yet have a mechanism for Crohn's disease.

Knowledge is power

Dr Simpson pulls no punches when giving you the facts but delivered in a way that is interesting with heaping scoops of wit and humor.

world Extreme chef ,

Great stuff here! Or not stuffed

Great podcast Terry appreciate your myth busts always learning

KatrinaGS ,

Love this food podcast!

If you're an avid fan of all things food, biology and science - this is a GREAT podcast. Not only is the host a Doctor - but if you look deeper - he's a bariatric surgeon - which really helps with his view on how food works within our bodies - not just tastebuds! I especially LOVE the food myths he continually busts! A true and verified show - with not just some "host" but a man who's gone to the University of Chicago, and backs all his facts with anotated notes - love it.
