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.

    The Beer and Sausage Diet

    The Beer and Sausage Diet

    The Beer and Sausage DietThere are a lot of crazy diets out there. All of them you can lose weight with. Weight loss has many advantages. But the beer and sausage diet was fun. Here is what we learned:
    A calorie is just a calorieBeing in calorie deficit is difficultMeticulous journaling is importantYour lab values will improve with weight lossA beer is a good unit measureWeighing your food is important
    Episode Sponsor: Modifyhealth.com
    I'm The DoctorIf you hear Evo Terra on national television talking about the beer diet, you will hear my name. I'm the doctor.
    Late one September, I get a call from my friend, Evo Terra. He said, "October is coming; I want to lose some weight and want to do a beer fast. "
    So we devise a diet, not just beer - but let's add sausages. After all, what is beer without sausages?
    Careful SupervisionThis was a medically supervised diet. It ran for the month of October every year for four years. Every week he would come into my clinic.  Every week he would have blood draws.
     cholesterol levels liver enzymesWeekly weightWe would check muscle mass vs. fat mass inflammatory markers
    We were prepared to stop the experiment and return him to a normal diet. For Evo, a normal diet is maybe not your diet.  Since Evo likes the food I make, I assume he has a great diet.  For many years, one of my great joys in Phoenix was when Evo and his wife would come over for dinner Sunday nights. Damn, I miss those days.
    There are advantages to beer and sausagesA beer is a single unit. There is little variation in terms of caloric intake.
    Sausage can easily be weighed, and Evo was strict regarding the weight of his sausages.
    We added vitamins and fiber to his regimen.
    He had six beers a day, and a designated driver at all times.
    Science WinsFor those who say grains are evil and you can never lose weight or you would have horrible inflammation, well, Evo didn't fit with that. Because no one does. The idea that grains are evil is a myth of the low-carb community.
    Vegans didn't like the idea of Evo eating sausages: "Pure processed meat will lead to inflammation and all the evils associated with eating meat."
    It didn't happen.
    Calorie deficit led to weight loss, despite drinking beer and eating sausages.
    His inflammatory markers didn't rise; they went down.
    His cholesterol went down.
    His liver enzymes decreased - not that they were high to begin with.
    Every year he kept his weight off - we are now over ten years past the last experiment.
    Conclusions:I don't recommend this as a weight loss method. I do recommend weight loss by the simple principles of calorie restriction, a well-rounded diet, and vigorous exercise. Which diet, you ask? Either the Mediterranean or the DASH diet.
    Evo wrote a book, and you can buy it here.

    Losing Weight with Apps

    Losing Weight with Apps

    Losing Weight With AppsCan a phone app help you lose weight? How about with your cholesterol, blood pressure, or waist size?
    Perhaps you've heard the latest Noom ads, where they boast forty publications showing that their app will help you lose weight.
    Apple is coming out with more ways to have their new watch track your heart rate and steps, with apps even looking at your yoga workout and eventually telling your blood glucose.
    Episode Sponsor: Modifyhealth.com
    What the Studies ShowA recent meta-analysis of randomized controlled trials showed that the average weight loss in the first three months was slightly below five pounds (2.18 kg).
    Unfortunately, the weight loss didn't last.  Nine months later, they had regained a pound and a half for a total loss of 3.5 pounds (1.63 kg).
    Blood Pressure, Cholesterol, and CaloriesThere was a slight improvement in blood pressure at three months. But cholesterol and total energy intake, as well as waist circumference and blood glucose, remained the same.
    The Proliferation of AppsThere are over 500,000 applications on Android and Apple phones to track various health data points. In addition, there are other devices just measuring fitness. The theory of measuring fitness behaviors with calorie tracking to provide feedback to improve health is appealing.
    Many Apps With Poor QualityMany apps had a lack of behavioral coaching and poor quality of scientific information. Tracking over a three-day period found that the accuracy of energy intake among apps was only fair in terms of total calories and amounts of macro- and micronutrients.
    What About NoomNoom is one of the more popular paid apps. They boast over 40 peer-reviewed articles. A quick glance at the articles showed some surprising flaws:
    One article compared Noom in pancreatic cancer patients to a control group who received no coaching.
    Another article used Noom data for their references.
    Article after article that Noom sites are little more than using Noom's data without dropout rates.

    Decreasing Cholesterol drugs and diet

    Decreasing Cholesterol drugs and diet

    Decreasing cholesterol: drugs and dietThere is a persistent belief that lifestyle can take care of all cholesterol problems. Lifestyle can make things worse, but once things are worse, it cannot make things better.
    Once you have disease, or cholesterol is higher, you need treatment often beyond lifestyle management.
    This distresses many people, who wish to have control over their fate.
    High cholesterol is one of the main causes of heart attacks, strokes, and peripheral vascular disease. You can lower cholesterol through diet and exercise by as much as 15 percent. Lifestyle changes are the first choice to decrease cholesterol. Modern drugs, however, will lower cholesterol levels far more than diet or exercise.
    The progressive changes of a vesselThe normal artery, as shown below, is a free-flowing blood vessel. When a person is in their late teens, there is already fatty formation on the inside of the vessel wall.
    As more fat is deposited in the vessel wall, blood flow decreases, leading to ischemia in the end organ.
    Angina, or heart pain, occurs when there is insufficient blood flow to the heart secondary to an artery narrowed by plaque.Factors contributing to atherosclerotic plaque formationDamage to the blood vessel begins the process of
    SmokingHypertensionHigh blood sugarsDiets rich in saturated fats and refined grains
    However, the lower the level of LDL, the less risk those factors become, as you shall see.
    Anatomy of the Blood VesselIf you examine the autopsy specimen of the coronary artery above, the blood flows through that lumen. The inner wall, the wall the blood comes into contact with, is called the endothelium. There are three layers to the wall of an artery:
    Tunica intimaTunica MediaTunica Adventicia
    Atherosclerosis begins when the cholesterol transport protein enters the wall of the tunica media, whose first layer is the endothelium.
    Discovery of LDLIn 1954, Dr. John Gofman reported the discovery of LDL and HDL. These were the particles found when he separated plasma cholesterol-carrying lipoproteins with an ultracentrifuge. Gofman was the first to note that heart attack patients had high LDL levels. The correlation of high LDL and heart attacks has been called “one of the most profound epidemiologic correlations in all of medicine.”
    High LDL levels have been shown to correlate with atherosclerosis in all species studied.
    High LDL and AtherosclerosisThe higher the LDL level, the faster atherosclerosis develops. Factors that increase atherosclerosis are those which injure blood vessels: smoking, hypertension, hyperglycemia, and genetic factors that predispose endothelium to early injury.
    High LDL levels can lead to heart attacks in children as young as 6 years old. This rare form of homozygous familial hypercholesterolemia inspired Brown and Goldstein to elucidate the genetic defect in the receptor for LDL.

    Alcohol and the Mediterranean Diet

    Alcohol and the Mediterranean Diet

    Alcohol and the Mediterranean DietAlcohol consumption is controversial.  No one disputes that excess alcohol consumption leads to dire consequences. But what about moderate alcohol consumption? Can we define moderate alcohol consumption? Is there a safe and therapeutic level of alcohol consumption?
    Alcohol is a component of the Mediterranean Diet. However, the consumption is limited to 10 ounces of red wine for men, which translates to 14 grams of alcohol. Half that amount for women. In a number of articles, this amount of alcohol is beneficial.
    Bias from AuthorsConfirmation bias is ingrained in all humans.  Treatment programs for alcohol addiction teach that there is no safe level of alcohol consumption.  Fundamentalist Christians, Muslims, and other organized religions have taboos regarding alcohol consumption. Finally, consumers of alcohol will be biased against abstinence.
    Components of WineIn their article, Wine, Polypenols and Mediterranean Diet, the authors note that one can get polyphenols from other sources in the diet, and thus the alcohol may be unnecessary.  They conclude that moderate consumption is likely an important component of a mechanistic as well as social norm.
    Dose Dependent Effects of Polyphenols on the BodyDecreased risk of cardiovascular diseaseDose-dependent reduction of LDL-CIncrease HDL-C and decrease triglycerides in patients with diabetesReduction of Blood PressureIncrease production of nitric oxide (NO), which increases blood flow and reduces blood pressureImprove LDL/HDL ratioResveratrol inhibition of pro-inflammatory agentslower risk of type 2 diabetesResveratrol improves glucose homeostasisModulate gut microbiotaImprovement in blood vessel wall function (endothelial function)Reduction of drugs in diabetic patients
    Mechanistic vs HolisticThe issue with the Mediterranean Diet is always those who approach from a mechanistic view versus those who approach nutrition and lifestyle from a holistic view. The original data from the Mediterranean Diet came from the Seven Countries Study. This was a holistic examination, not only of their diet but also their lifestyle.
    Alcohol Toxicity is in the DoseA bit of wine is good, a lot of wine is not.
    If you look at every improvement in human physiology with alcohol listed above, the opposite effect happens when the dose is beyond about 50 grams of alcohol.

    Mediterranean Diet After Weight Loss Surgery

    Mediterranean Diet After Weight Loss Surgery

    Mediterranean Diet after weight loss surgerySuccess after weight loss surgery doesn't end with an operation. It just gets started.
    The most recalcitrant people to diets are those who undergo weight loss surgery. Weight loss surgery patients were on multiple diets prior to surgical intervention.  The Mediterranean Diet is the best post-operative diet one can have.
    Weight Loss and the Mediterranean DietThe Med Diet is favorable for health. Multiple studies have shown decreased risk of cardiovascular disease, cancer, and autoimmune disease. What about weight loss? Systematic reviews have shown the Med Diet is equal or superior to other diets for weight loss. However, we found no post-operative program to adopt the Med Diet after weight loss surgery.
    Preoperative Med DietWe began coaching patients with the Med Diet before surgery. Many insurance companies require a preoperative, physician-supervised diet. In 2010, we began to use the Mediterranean Diet as a template for our patients using the 9-point scale.  Contrary to weight loss plans, our emphasis was learning the Med Diet.
    Weight Loss Surgery Protocol Liquid PhaseThe immediate post-operative diet emphasized soups and smoothies rich in legumes, vegetables, and fruits. Modular, unflavored protein supplements (whey or pea-based) were used to augment the protein content during this time, as were standard chewable vitamins.  Thus, the beginning of the post-operative plan was already a rich Mediterranean-style diet.
    Early Solid Food PhaseLegumes and fish were emphasized during the early solid food phase, which were universally easy to digest. One of the favorite Mediterranean-style foods were tacos.  Contrary to popular belief, the Med Diet is not foods commonly eaten in the Mediterranean. Instead, it consists of foods rich in whole grains (corn tacos), fruits (homemade salsa), legumes (lentils), some dairy products (cheese), and fish.
    We noted lettuce was problematic for some in the early phase, but spinach was easy to digest. Thus salads were based upon spinach rather than lettuce.
    Later Solid Food PhaseAs the stomach continued to heal, we stressed the increase in food with multiple fiber types.  We de-emphasized red meats, cautioned against excess alcohol, and worked on olive oil as the primary source for fats.
    Follow upCooking classes were a constant feature of our support group, often bringing in guest chefs from the area and the Food Network. We emphasized the importance of patients learning to cook.  Many of our patients believed that cooking was the most important aspect of their postoperative care. We found that those who learned to cook their meals had better weight loss than those who did not.
    Validated Food Frequency Questionnaires (FFQ) were used to follow a group of patients. The FFQ were validated using dietary logs during follow-up with patients.
    Getting in that quantity of foodStomach capacity after weight loss surgery is limited. How, then, does one get in the required amount of food? It is not difficult.
    All food is measured pre-cooked. Take broccoli. If you take nine ounces of broccoli and bake it, you end up with a small amount of volume but still have the one Mediterranean Diet point.
    The increase of vegetables in the diet is one way to reduce inflammation.
    Food increases over timeFood volume increases over time with both the Gastric Sleeve, Lap-Band, and RNY gastric bypass. The answer is not to eat less or take more protein shakes. The...

    Implementing the Med Diet - Part One

    Implementing the Med Diet - Part One

    Implementing the Med Diet - Part OneDo you think you eat enough plants in your diet? How many plants do you eat in a week? Not refined grains, but plants. You can cook them, boil, bake, microwave, roast them or even eat them raw. How many? Further, it's not just eating more volume of plants, it's diversity.
    Mediterranean Diet and PlantsAdherence to the Mediterranean diet depends more on plants.
    VegetablesFruits, Tree Nuts, SeedsLegumesWhole GrainsOlive oil
    When it comes to plants, more is better. But not just in quantity of plants, but also diversity.
    Think about this: there is no one plant that can provide all the micronutrients and macronutrients a person needs. We tell vegetarians to use several plant sources for complete proteins, the same is true for any nutrient.
    Gut Bugs and PlantsYour gut contains a trillion bugs. There are more of them than of us. But what do they eat? It turns out, most of what they eat are the things we don't. Gut bugs eat plant parts. Without them eating those plant parts, we would be far worse off. Thus, the gut microbiome is an exciting research field.
    Guts break down fiber to chemicals shown to:
    Decrease the risk of colon cancerLower cholesterolDecrease blood sugar spikesDecrease depressionAllow absorption of polyphenols
    Fiber is an Essential NutrientPlants provide vitamins, minerals, macro and micronutrients. A single source of plants cannot provide the nutrients a person requires, which has been the main reason we recommend a diversified diet. Fiber is also a nutrient, an essential nutrient, one that humans cannot make, but without it there is clearly an increase in disease. While those on the extreme of low-carb diets will disagree, the literature is unambiguous.
    MythFiber supplements are not a substitute. Some are expensive, one selling for over $150 a month. But no supplement gives you the diversity of nutrients that you can get from your diet. Mother Nature gives you a better deal. So, eat your fiber, don't buy a supplement.
    Now begin to chart your diversityToday's assignment is simple: begin to chart the diversity in your diet, so that you increase the sources of your plants. One of my favorite dieticians, Dr. Megan Rossie, suggests a person has 30 plant-based foods per week. Sound impossible? Let's try it using the Meditereanean Diet.
    Why 30?It isn't that difficult to implement, but consider that you want to consume the vitamins, minerals, antioxidants, and other nutrients, and there is no one plant that does this. But many will.
    Vegetables:One Mediterranean diet point is achieved by consuming 9 ounces of vegetables per day.  Run through the list of vegetables that you can add to your diet in any given week.

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.
