  • Stop Buying Organic on the Wrong Foods

    Stop Buying Organic on the Wrong Foods
    2026/03/20
    Chef Martin Oswald and I filmed this live from two different continents (he was in Austria, I was in the U.S.) and we spent over an hour fighting technical issues before we actually got the thing to work. So if you watched live and stuck around through all of that, thank you. Genuinely.Once we got going, we covered three things. The dirty dozen. The clean 15. And then a conversation Martin wanted to have about what he calls “beyond organic,” which turned out to be the part I found most interesting. The video is above if you want to watch us actually cook. What is below is everything we talked about, organized so it is easier to use.The Dirty DozenThe Environmental Working Group publishes an annual dirty dozen list, which identifies the twelve produce items most contaminated with pesticide residues. Research consistently shows that pesticide exposure, even at low chronic levels, is associated with hormonal disruption, metabolic dysfunction, and increased inflammation. For anyone focused on metabolic health, this is not a footnote.The current U.S. dirty dozen includes strawberries, spinach, kale, grapes, peaches, pears, nectarines, bell peppers, cherries, blueberries, green beans, and apples. These are the items where buying organic makes the biggest practical difference, and where Martin and I both agree you should not compromise if budget allows.One thing worth knowing is that the dirty dozen varies by region. What is highly contaminated in Colorado may not match what is sprayed heaviest in California, and international listeners will have their own regional variation to consider. The EWG list at ewg.org is updated each year and is a reliable starting point, but it reflects primarily U.S. data.Potatoes deserve a special mention because people often assume that anything growing underground is somehow protected. Martin explained pesticides applied at the soil surface do penetrate down, and the bugs that target root vegetables are prolific. Conventional potatoes are consistently among the more contaminated options, so organic matters there too.During the live, Martin put together what he called a Dirty Dozen Salad. It is a spring arugula base with blueberries, raspberries, and roasted pistachios and almonds, topped with quinoa he had seasoned during cooking with clove, cinnamon, black pepper, and a little chili. The dressing was something I want to make every week. Strawberries, garlic, yogurt (plant-based works fine), a splash of vinegar, lemon zest, lemon juice, and optional mustard and basil, all pureed into a vivid pink dressing. I know garlic and strawberry sounds counterintuitive. I had the same reaction. Martin’s point is that garlic works beautifully with greens in a Caesar, so when you think of it as dressing the greens rather than pairing with the strawberries, it clicks. His one technique rule is to dress only about two-thirds of your greens, never the full amount. Over-dressing weighs the salad down and makes it go soggy fast.Click here for the recipe. The Clean 15On the other end of the spectrum, the clean 15 are the items least contaminated with pesticide residues. These are produce with thick skins, natural pest resistance, or growing conditions that make heavy spraying unnecessary. Buying conventional versions of these is a reasonable, evidence-informed way to save money and redirect it toward the dirty dozen.The current clean 15 includes avocados, sweet corn, pineapple, onions, papaya, sweet peas, asparagus, honeydew melon, kiwi, cabbage, mushrooms, mango, sweet potatoes, watermelon, and carrots.Martin added some nuance here that I found useful. Radicchio and bitter greens generally have some of the lowest contamination levels of any produce you will find, not because they are grown organically but because insects do not want them. Bitter compounds are a natural defense mechanism. Martin said it simply during the session: “Bitter is better.” These are also some of the most potent liver-supportive foods available, and in his view, underused by people who could benefit most from them.White asparagus is worth a specific note. In Austria, it is grown completely covered by mounded soil to protect it from light, which also means it is naturally shielded during growing. As a result, it tends to have very low contamination even in conventional form. Green asparagus is equally good. Both are clean 15 options that are also nutritionally strong.For the Clean 15 Salad, Martin demonstrated a technique I am now going to use regularly. He cut cabbage, carrots, asparagus, and English peas into small, even pieces, then steamed them in a covered pot with just a splash of water for three to four minutes. After steaming, he immediately transferred them to cold water to stop the cooking and preserve the color. He then dressed them with whole grain mustard, flat-leaf parsley, and an avocado-based dressing he had prepared with sesame, ginger, soy, miso, rice vinegar, and lime juice. In lieu of salt, ...

  • Why Can a 150-Pound Man Get Diabetes When a 300-Pound Man Does Not?

    Why Can a 150-Pound Man Get Diabetes When a 300-Pound Man Does Not?
    2026/03/18

    Why can a 150-pound man develop Type 2 diabetes… while a 300-pound man does not?

    For decades, we were told a simple story: gain weight, get sick. Stay thin, stay safe. But that story falls apart the moment you look at real patients.

    In this episode, I walk you through the concept that changed how we understand diabetes: the Personal Fat Threshold.

    I explain why the issue isn’t how much fat you carry — it’s where your body can safely store it. Some people are born with a metabolic “bathtub” the size of a swimming pool. Others have a kitchen sink. When your personal storage limit is exceeded, fat spills into places it doesn’t belong — your liver, your pancreas, your muscles — and that’s when the real trouble begins.

    We unpack:

    * Why BMI is a blunt and often misleading tool

    * What “ectopic fat” is and why it drives insulin resistance

    * The Twin Cycle hypothesis and how liver fat and pancreatic fat feed each other

    * Why beta cells in Type 2 diabetes may be stunned — not dead

    * And why early diabetes can often be reversed

    Then I explain something hopeful.

    When you “drain the tub” — often by losing 10–15 kilograms — liver fat drops within days. Blood sugar can normalize within a week. Over weeks, the pancreas begins to recover. In many cases, diabetes goes into remission.

    This isn’t about perfection. It’s about crossing back below your personal threshold.

    Finally, I share how we translated this science into the 30-Day Blood Sugar Reset — a simple, daily micro-habit approach designed to lower the pressure on your liver and pancreas without turning your life upside down.

    Because diabetes isn’t a moral failure.It isn’t a willpower problem.And it isn’t always about how you look.

    It’s about overflow.

    And overflow can be drained.Dr. Marbas Substack: https://drlauriemarbas.substack.com/

  • Is Your Brain Getting Fed? The Micronutrients Most of Us Are Missing

    Is Your Brain Getting Fed? The Micronutrients Most of Us Are Missing
    2026/03/13
    Chris Miller MD and I went deep on this one. We sat down for a Friday live and covered something that gets overlooked in the constant noise about macronutrients, protein targets, and which diet trend deserves your attention this week. We talked about the micronutrients that actually keep your brain and body running, the ones most people never test for, and what happens when they quietly fall short.If you watched the replay, this is your reference guide. If you haven’t watched yet, start with the video above and come back here for the details.Your Brain Has a BouncerBefore we got into specific nutrients, Dr. Miller explained something worth understanding: the blood-brain barrier. Your brain is picky about what it lets in. Unlike your gut lining, which is one cell layer thick and held together by tight junctions, the blood-brain barrier is roughly 400 times tighter. It has to be. Your bloodstream carries immune cells, toxins, and pathogens that would cause serious damage if they reached your brain tissue.Specialized cells called astrocytes, pericytes, and microglia wrap themselves around the blood vessels that supply the brain, creating a filtration system that only allows through what the brain actually needs: glucose via dedicated transporters, oxygen, carbon dioxide, and select nutrients. Everything else gets turned away.When this barrier is working well, the brain stays protected while the glial cells on the inside handle cleanup and maintenance. That is a healthy brain. And the nutrients that make it through that barrier are exactly the ones we spent the rest of the session talking about.Vitamin DDr. Miller started here because it is one of the most common deficiencies she sees, regardless of diet. You may not feel it right away, but signs can include slower wound healing, getting sick more often, autoimmune flares, and declining bone density.The test to ask for is a 25-hydroxy vitamin D level. I aim to get my patients into the 40 to 60 range. Below 20 is clearly deficient, and most physicians will agree with that. Research during the pandemic showed that individuals with levels closer to 46 to 50 had less severe infections, which tracks with what we know about vitamin D’s role in immune and cardiovascular protection. It functions more like a hormone than a simple vitamin, and your whole body depends on it.Here is the thing that surprised me about my own levels. I have lived in sunny places for most of my life. I run outside regularly without sun protection (yes, I know). And I have never been able to get my vitamin D above 30 without supplementation. There are genetic variations that affect your ability to convert sunlight into usable vitamin D, which is why testing matters more than assumptions.Most of my patients do well on around 2,000 IU daily, but this is individual. I would not take over 4,000 IU without a physician monitoring your levels, because toxicity is real. NatureMade is a reliable, affordable brand you can find at any pharmacy or Walmart.MagnesiumThis one comes up constantly. Even people eating a solid plant-based diet can fall short. The challenge with magnesium is that blood tests are unreliable. Only about 1% of your total magnesium circulates in your blood, so a serum level can look normal while your tissues are depleted. An RBC (red blood cell) magnesium test is somewhat better, but still imperfect.Pay attention to symptoms: muscle cramps, especially if you are on a diuretic like hydrochlorothiazide. Difficulty sleeping. Muscle twitching. Anxiety. Heart palpitations. Migraines. Headaches. Constipation. As we get older, the cramping and sleep disruption tend to be the most common complaints.For food sources, pumpkin seeds are a powerhouse. I eat them every single day. Dark chocolate (you are welcome), avocado, almonds, and leafy greens are all solid sources. But if you have gut issues, if you are gassy or bloated or dealing with loose stools or constipation, there is a good chance you are not absorbing well. Aging also reduces stomach acid, which compounds the problem.Someone asked during the live what the best form of supplemental magnesium is for muscle twitching. Dr. Miller and I both recommend magnesium glycinate (or bisglycinate), 200 to 400 milligrams. It absorbs well and is less likely to cause the GI side effects you might get from other forms.Omega-3 Fatty AcidsDr. Miller brought this one up because of her focus on inflammation and healthy aging. What your body really needs are EPA and DHA, the two omega-3 fatty acids that do the heavy lifting for joint health, cardiovascular protection, and brain function. DHA in particular is critical for the brain, and people who carry the APOE4 gene may need even more of it to get adequate amounts across the blood-brain barrier.If you eat fatty fish like salmon, mackerel, anchovies, sardines, or herring, you are getting pre-made EPA and DHA. If you eat plant-based, you can get ALA from flax seeds, chia seeds, walnuts, hemp seeds,...
