• Bread: The Evil Staff of Life
    Jul 10 2024
    Should I eat bread?

    The low carbohydrate movement has demonized bread. But is bread fattening? Does it cause inflammation? And if so, why do we call bread the Staff of Life?

    The Staff of Life

    Imagine calling white bread the staff of life. And yet bread is more responsible for humans ending a nomadic existence. The cultivation of wheat and barley, both in the Nile and in the Euphrates/Tigris rivers, led to civilization.

    Calendars, Art, Religion

    Not having to forage meant there was time to build a more permanent shelter. It also meant a steady supply of food.

    This also meant a calendar was needed because when is the optimal time to plant?

    The calendar helped predict when the rivers would swell and recede. The bottom land, with its rich topsoil, is ideal for growing crops.

    When you don't need to spend time looking for food, you have time to develop other things:

    • Make a religion around grains - the god of the weather, of the earth of the river
    • Grain can become the first currency, facilitating trade
    • Art because you spend less time seeking food
    • Storage systems to overcome times of famine.
    • Mathematics, weights, and measures are needed to buy and sell grain
    • Writing to make contracts and facilitate trade of the grain
    • A government is needed to settle disputes

    Storage Systems

    Harvested grain can be stored. Storing grain in Egypt was easier because of the dry climate. Joseph, of the Hebrew Bible, prophesied to the Pharoh of an upcoming famine. As a result, the Pharoh built silos and stored a portion of each harvest. Seven years later, the harvest failed. But

    The silo system was complex. Filling from the top and arranged in a way that winds would keep the grains cool. Where did Egyptians get the idea for such an invention? From bees. You can see the bees' natural ventilation system here:

    Bees were the symbol of royalty in ancient Egypt. Their honey was tears from the sun god. Bee architecture was copied for the ventilation system for the silos storing grain. Thus, the storage of grain allowed society to thrive during the time of famine.

    Bronze Age to Iron Age

    Bread was portable. Served as currency. Allowed armies to march. Facilitated trade between city states. The grain rich regions of the Nile produced grain traded with Mycennians for olive oil and wine.

    The Roman emperors gave bread to the poor as welfare. Part of the bread and circus program to keep Romans happy. Bread was imported to Rome, and ultimately, Roman citizens were given "their daily bread."

    Rome fell, but bread continued to be important.

    Bread until 1920

    Grains, including bread, were the major source of calories for most of Europe. From the fall of Rome through the Middle Ages, bread was the main source of calories, along with other grain products.

    Bread in the Industrial Age

    White bread was considered pure, hygienic, the whiter the better. Brown bread could be contaminated. The ability of mills to separate wheat from chaff, and to make bread without a human hand touching it was irresistible. Industrial bread slicing resulted in "best thing since sliced bread."

    White bread became the preferred style of bread from the 1920s until 2009.

    Fortification of bread with vitamins in the 1940s made bread a health food. Pellagra (vitamin B 3 deficiency) and beriberi (thiamine deficiency) had sadly become common in the US and were eliminated by fortification. So it was indeed revolutionary, but calling it a health food? Even the Federal Trade Commission had issues with this "12 ways campaign" and sued Wonder Bread. The Feds lost.

    Age of Aquarius Beats Bread

    In spite of the world loving white bread,

  • Seed Oils: Toxic or Not?
    Jul 1 2024
    Seed Oils: Toxic or Not?

    Today, the low-carb/carnivore community has a new enemy. It is seed oils. Here is their argument:

    • There were no seed oils in ancient lands
    • Seed oils are highly inflammatory
    • Seed oils are extracted with hexane, a cancer-causing agent
    • The rise of seed oils correlates with the rise of obesity
    • Seed oils are high in omega-6 fatty acids, which are inflammatory

    That is the summary of their logic. Now, let's get to the science.


    What are Seed Oils?

    See those beautiful seeds, in them are bits of oil. This is the rapeseed plant, which we have covered before. From rapeseed came canola oil. And this has been used as a source of oil starting about 4000 years ago. A much misunderstood oil, please see our previous podcast.


    Seed Oils

    Every seed has oil. Nuts are a type of seed, and their caloric density comes from oil. Oddly, low carb/keto types tend to eat nuts, the carnivore crowd avoids them.

    Seed oils are another name for vegetable oils, and they are used often in cooking because they have a neutral taste and high smoke point. The more common ones include corn, peanuts, sunflowers, grapes, and others.


    Seed Oils and Ancient Humans

    Besides the logical fallacy about what ancient humans ate, seed oils have been cultivated and used for the whole of written humanity. Ancient Egyptians used oils for cooking and perfume. Even the Bible talks about the use of oils, including the gifts sent to the birth of Jesus. To summarize, humans have recorded the use of oils from seeds through all recorded history.


    Components of Seed Oils

    There is no one "oil" that can chemically be called a "seed oil." Rather, every seed contains different compositions of oils, and it is how the body uses those particular oils that makes us interested in them. Thus, seed oils as a term is silly. I wonder why the carnivore/keto crowd decided to use "seed oils" instead of vegetable oils? After all, they don't call beef tallow "meat oil."


    Oleic Acid: Olives to Butter

    Oleic acid is the main fatty acid in olive oil (55-85% of the oil). This is a mono-unsaturated fatty acid, which everyone seems to agree is heart healthy. Hence, the more oleic acid in something, the better.

    • Peanut oil 48%
    • Canola oil 65%
    • Palm oil 39%
    • Soybean oil 23%
    • Coconut oil 7%
    • Beef Tallow 47%
    • Butter 24%

    But are Vegetable Oils Inflammatory?

    The short answer is no. To be inflammatory, they would have to elicit an inflammatory response. This means that inflammatory markers in the blood would be elevated for those who use vegetable oils over meat oils. In contrast, there is no increase in inflammatory markers of those who use vegetable oils.

    Want to see the data? Take a look at this paper where they look at foods, like vegetable oils, with high ratios of omega-6 fatty acids. What didn't they find? Higher levels of inflammatory markers. Thus, seed oils are not inflammatory.

    Atherosclerosis and Seed Oils

    Do vegetable oils increase your risk of atherosclerosis, or do they decrease it? If the carnivore crowd is correct, they have not been yet, then their view of the vegetable oils is that it would increase your risk of atherosclerosis

  • Ancestral Diets and Logical Fallacies
    Jun 19 2024
    Ancestral Diets and Logical Fallacies

    There is an appeal to ancient history: the idea that ancient beings were either "designed"—as from a creator—or "evolved" to eat in a certain way. Both are logical fallacies, but both are meant to be the "ex-cathedra" in a debate.

    You read these logical fallacies in communities that claim they understand this. Here are some comments you will get:

    • Our ancestors ate xyz (fill in the blank) and never had the modern chronic diseases
    • Our teeth have (canines/molars), so we were designed to eat only (meat/plants)
    • You won't see broccoli on the walls of caves
    • If we ate like our ancestors, we would be in great health.

    Appealing arguments, but they are as flawed as they are simply incorrect.


    What Do We Know About Early Humans?

    Of the early human records, they are based on precious little data. Consider in the fossil record we have about our ancestors? And by the way, where do we start?

    If we begin with homo sapiens, we have been around as a species somewhere between 70,000 to 250,000 years.

    Often the "low-carb" community will conflate distant cousins of homo sapiens as direct ancestors. Most of them were not but were a branch on the tree of evolution that are only related to us.


    Homo Erectus

    Perhaps the best adapted was the homo erectus, which was around for two million years. It is doubtful that homo sapiens will make it that long, but we can hope.

    Most fossil finds come from Australia and Asia - where they not only foraged but also established some organized hunting.


    Fossil Records

    There are about 6000 fossils of early man. That's it. Just 6,000. When we look for fossils of our particular, such as early homo sapiens, we have enough fossils that we might fill up a school bus.

    How long did they live? It turns out we know. Many died around the age of 35 years. So why do we want to eat like they did?

    At this point, someone in the audience will be bound to say - "They lived longer if you take into account infant mortality."

    When we date a fossil and see when it died, we don't average the infant mortality of the time.


    Recent Discoveries

    Bones and teeth from seen people, and isolated teeth, were reported recently. These came from a cave in Morocco. As these teeth are from about 15,000 years ago. Hence, the diet was before the advent of agriculture.

    Evidence points to plants being a major part of these hunter-gatherer's menu. As plants can be stored by hunter-gatherers all year round to protect against seasonal prey shortages. Thus, there is a regular food supply.


    Hunter-Gatherers

    The famous caveman diet- life wasn't so simple.

    When people of the carnivore tribe try to convince you about their diet, they invoke the mighty hunter.

    A better term was that our ancestors survived by being fishers, gatherers, and scavengers.

  • Rice and Fruit or Carnivore
    May 8 2024
    Rice and Fruit or Carnivore

    The rice diet successfully treated malignant hypertension. Today, we have medications that treat malignant hypertension. Before the 1940s, there were no drugs available to treat this disease, resulting in death from untreated malignant hypertension within six months. Despite the best medical care available, President Franklin Delano Roosevelt died from this disease.

    History of the Rice Diet

    Walter Kempner developed the rice diet to treat malignant hypertension. For example, failing kidneys would be given a reprieve with a diet low in sodium and protein. Then removal of saturated fat would allow some recovery of the heart.

    In a disease that had 100 percent death in six months, Kempner's results were amazing. For example, in Kempner’s original cohort of 192 people, only 25 patients died. In addition, 107 patients showed significant improvement (from 200/112 mm Hg to 149/96 mm Hg) with the diet. Equally important, heart size decreased in 66 of 72 patients. Moreover, cholesterol was reduced in 73 of 82 patients. Finally, retinopathy improved or disappeared completely in 21 of 33 patients.

    "Therapeutic results are little short of miraculous," noted an editorial in the New England Journal of Medicine.

    The Rice Diet

    Patients were first hospitalized. The diet consisted of white rice, sugar, fruit, fruit juices, vitamins and iron. Total calories were 2,000 with 20 grams of protein and 150 mg of sodium.

    Kempner kept careful records of his patients. Reporting success and failure is a key to academic transparency. Finally, the ability to reproduce the data in other centers provided the final key to Kempner's work.

    Contrast the Carnivore Diet

    The carnivore diet is popular among young, buff men whose living is made by promoting and coaching this diet. They sell the diet based on classic marketing techniques used for overweight patients.

    • Lose weight without trying
    • No need to log your food
    • Eat as much as you want
    • Hunger isn't an issue

    Marketing phrases used by hucksters for years to trap people unhappy about their weight.

    No Science in the Carnivore Diet

    The carnivore diet relies on anecdotes, not evidence. Testimonials rule Facebook and YouTube sites. There are no publications about the diet. Finally, many in the carnivore community push against medicine. Conspiratorial thinking is strong, with phrases like this:

    • Doctors want you to be sick
    • The Medical Community wants to push pills
    • Vegetables have anti-nutrients

    Try to raise a concern about how this diet would increase the risk of heart disease, and they double down with misinformation. They will deny the evidence showing that high cholesterol leads to heart attacks and strokes. Or make the claim that if you are "metabolically healthy," you don't need to worry about cholesterol.

    No Academic Researchers

    There are no academic research scientists following people trying the carnivore diet.

    That means there is no transparency about the results. In addition, there is no accountability for any bad results.

    Those who promote the diet include Paul Saladino, a physician who doesn't see patients and makes his income selling supplements.

    The Liver King, who doesn't follow the diet, was caught using performance-enhancing drugs.

    Shawn Baker is an orthopedic-trained surgeon who lost his medical license and makes his money promoting the carnivore diet. The New Mexico Medical Board ordered the "voluntary and permanent...

  • Grains on the Mediterranean Diet
    Apr 10 2024
    The Benefits of Whole Grains in Your Diet

    I want to take you back in time. While we talk about the Mediterranean diet not being a diet of culture but a pattern of eating – it still had its origins in the Mediterranean.

    The original Mediterranean diet was described as far back as 500 BC in the Ilead. The ancient Greeks ate whole grains, fruits, vegetables, pulses, and a bit of fish. Red meat was rare.

    While red meat may not have been a dietary staple for the Ancient Greeks, it was consumed during feasts, festivals, and special occasions.

    Cows were considered sacred gods, like Zeus, and their slaughter was for religious ceremonies and consumed during feasts

    The majority of the population received protein from fish, poultry, legumes, and whole grains.

    The First Olympics

    This was the diet of the first Olympians, as well as the Romans. Ancient Greeks worshiped the body, as you can see from the statues, as well as our language.

    We get the word gym from the Greek word “gymnasion," which translates to a place to exercise naked. But those gyms not only had a place to train but also schools, where literature, philosophy, math, and music were taught, as well as a social gathering place.

    We also get Diet from the Greeks, which originates from “diaita,” meaning the “way of life” or a manner of living. The Greeks had a balanced approach to health and well-being, emphasizing diet, exercise, and the mind.

    Gym bros and bro science were yet to be invented.

    Ancient Grains

    Could those Olympians of old who ate diets filled with whole-grain cereals have been wrong? Or could it be that those grains of the past were different from today’s grains?

    If you’ve ever been on a “low carb” diet, one of the first food groups you eliminate are grains.

    As you dutifully got rid of the last bit of joy in your life, you feel it was the cost to have your weight drop.

    You might have thought – "Grains are evil."

    Low Carb Life Without Grains

    Eating burgers without the bun, breakfast without toast, no pastries, no bread, no pasta, no rice, and you were losing weight. Lots of confirmation bias.

    Oh those heady early days of a low carb diet, losing weight, feeling better, maybe even noticing cholesterol improved. Hard to sustain though, and did you ever get tired of steak?

    Finding Joy in the Mediterranean Diet

    Now you come here and find the best diet is the Mediterranean diet. Lots of peer reviewed literature to support it.

    Then you wondered what in grains was evil. The first easy thought was that it all breaks down to glucose, and glucose is evil.

    Unless you know biochemistry and realize no, that’s not it. Your body runs on glucose.

    It's the Gluten

    And maybe you read about celiac disease and gluten as its trigger. Maybe some blogger convinced you that wheat in America is filled with gluten, and this is the problem.

    Unable to sustain a low-carb diet, you return to the joy of the morning pastry or dessert, all the while thinking grains are what caused the weight to return.

    Now you come to the Mediterranean Diet, and whole grains, not refined grains, are on the menu.

    Still, you are suspicious, and you think – maybe it was the gluten.

    Celiac Disease

    Or what happens if you come to the Mediterranean diet and have Celiac disease and gluten causes horrific issues?

    But should we all avoid gluten? And can we have a Mediterranean diet if we must be gluten-free?

    Should the ancient Greeks become Carnivores instead of those grizzly men who are on a diet now associated with the healthiest people on planet Earth?

    Clearly not. Eating too much red meat is associated with increasing heart disease and cancer, while the Mediterranean diet is associated with less heart disease and cancer.

    Carnivore's Take

    Carnivores like pointing to the ancient...

  • Health Benefits of Fish Consumption
    Mar 1 2024
    Health Benefits of Fish Consumption

    Fish consumption has been linked to various health benefits due to its rich nutritional profile. The health benefits of fish consumption include cardiovascular health, brain function, and well-being. Because fish are a rich source of omega-3 fatty acids, vitamins, minerals, and other nutrients, they are an important part of a balanced diet.

    Fish, the Most Ancestral Food

    Fish has long been recognized as a valuable source of essential nutrients beneficial for human health. Seafood is a staple part of the diet across different cultures and regions. Since most of the first human communities were coastal, fish were a common source of food.

    Cardiovascular Health Exceeds Risk

    Regular fish intake reduces the risk of cardiovascular diseases, such as coronary heart disease and stroke (Mozaffarian & Rimm, 2006). That study showed that the benefits of fish intake exceed the potential risks. Even for women of childbearing age, the benefits of modest fish intake, excepting a few selected species, also outweigh the risks. The heart health effect comes from the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) found abundantly in fatty fish species (Kris-Etherton et al., 2002). These fatty acids exert anti-inflammatory, antiarrhythmic, and vasodilatory effects, lowering blood pressure and triglyceride levels and reducing the formation of blood clots (Calder, 2015).

    Brain Function

    Fish consumption has also been associated with improved cognitive (brain) function and a reduced risk of brain disorders such as Alzheimer's disease. The omega-3 fatty acids EPA and DHA play a crucial role in brain health (Gómez-Pinilla, 2008). Epidemiological studies have consistently shown a positive correlation between higher fish consumption and better memory (ref). Moreover, research suggests early-life exposure to seafood has long-term brain benefits and decreases age-related cognitive decline (Wurtman et al., 2009).

    Nutrient Profile, Such as Vitamin D

    But omega-3 fatty acids are not the only benefit of eating fish. Fish are also a rich source of various essential nutrients vital for human health. Vitamin D, in particular, is naturally abundant in fatty fish and plays a crucial role in bone health, immune function, and mood regulation (Holick, 2007). These include high-quality protein, vitamins (such as vitamin D and B-complex vitamins), and minerals (such as selenium, iodine, and zinc) (Kris-Etherton et al., 2002). Furthermore, the bioavailability of these nutrients from fish is superior to other dietary sources, including supplements. Thus, fish consumption is an efficient means of meeting nutritional requirements (Rosell & Appleby, 2006).

    Fish Farms

    Aquaculture, the farming of fish and aquatic organisms, has undergone significant advancements in recent years, leading to improvements in sustainability, efficiency, and product quality. Fish Farms have had significant problems in the past. In the last fifteen years, there has been an improvement in environmental management strategies and sustainable farming practices.

    Those practices have changed my mind about seafood. Consequently, you can now buy quality farm-raised seafood, which adheres to the high standards of any food. Hence, I now recommend some...

  • Reducing Dementia with Diet
    Feb 15 2024
    Three Great Diets

    The Mediterranean diet, the DASH diet (Dietary Approaches to Stop Hypertension), and the MIND diet (Mediterranean-DASH Intervention for Neurodegenerative Delay) are all great eating patterns. Each diet focuses on different aspects of health.

    Mediterranean Diet

    The Mediterranean diet comes from the traditional dietary patterns of countries bordering the Mediterranean Sea, such as Greece, Italy, and Spain. High in the consumption of fruits, vegetables, whole grains, nuts, seeds, legumes, olive oil, fish, and moderate amounts of poultry, dairy, and red wine. Shown to decrease the risk of heart disease and cancer and to improve longevity.

    DASH Diet

    Discussed in last week's podcast (ref). DASH (Dietary approach to stop hypertension) was developed to prevent and manage hypertension (high blood pressure). Focuses on increasing intake of fruits, vegetables, whole grains, lean proteins, and low-fat dairy products while limiting sodium, saturated fats, and cholesterol.

    MIND Diet

    Developed by researchers at Rush University Medical Center as a hybrid of the Mediterranean and DASH diets, with a focus on brain health and reducing the risk of neurodegenerative diseases like Alzheimer's disease. It also emphasizes the consumption of fruits, vegetables, whole grains, nuts, olive oil, fish, poultry, and beans while limiting the intake of red meat, butter/margarine, cheese, pastries/sweets, and fried/fast foods.

    Three Diets are Branches of the Same Tree

    The Mediterranean, DASH, and MIND diets share some common elements. All focus on whole foods and plant-based sources of nutrients. The Mediterranean diet emphasizes health and longevity. While the DASH diet targets hypertension and cardiovascular health. Finally, the MIND diet specifically supports brain health to reduce the risk of neurodegenerative diseases.

    1. Rush Memory and Aging Project:

    A study conducted by researchers at Rush University Medical Center followed over 900 older adults for an average of 4.5 years. Findings showed that individuals who closely adhered to the MIND diet had a substantially lower risk of developing Alzheimer's disease, with a reduction in risk ranging from 21% to 53%, depending on the level of adherence. (ref )

    2. Columbia University Medical Center Study:

    Researchers at Columbia University Medical Center examined the dietary habits of over 1,000 participants. Individuals who closely followed the MIND diet had a 53% lower risk of developing Alzheimer's disease than those with low adherence to the diet.

    3. Alzheimer's Disease Neuroimaging Initiative (ADNI):

    The ADNI study found that adherence to the MIND diet was associated with better cognitive performance and a reduced rate of cognitive decline over time.

    4. Systematic Reviews and Meta-Analyses:

    Several systematic reviews and meta-analyses have summarized the findings of multiple studies investigating the association between the MIND diet and dementia risk. Overall, these reviews reveal that adherence to the MIND diet is associated with a significant reduction in Alzheimer's disease and dementia.

    5. Mechanisms of Action:

    Components of the MIND diet, such as leafy greens, berries, nuts, whole grains, fish, olive oil, and poultry, have been linked to improved cognitive function and a lower risk of dementia.

    More research is needed to elucidate the mechanisms underlying the protective effects of the MIND diet. Current evidence suggests that...
