The General Healing Diet: Food for Everyday Health

General Healing Diet

In the world of functional medicine, the saying "food is medicine" takes center stage. Unlike conventional dietary approaches that may prioritize caloric restriction or macronutrient ratios, the General Healing Diet focuses on the nutrient density, anti-inflammatory properties, and the ability of food to support the body’s innate healing mechanisms. Let’s explore the science behind this diet, its guiding principles, and three recipes to kickstart your journey toward vibrant health.


The Philosophy of the General Healing Diet

“Let food be thy medicine and medicine be thy food.” — Hippocrates

Functional medicine views health through the lens of interconnected systems. The General Healing Diet aligns with this approach by emphasizing whole, unprocessed foods that nurture the microbiome, regulate inflammation, and balance hormones. This dietary framework is not about deprivation but empowerment—teaching your body to thrive by providing it with the nutrients it needs to heal and perform optimally.

Scientific Backing:

  1. Gut Health: A study published in Nature (2019) demonstrated that high-fiber, plant-rich diets improve gut microbiota diversity, which correlates with reduced systemic inflammation. Soluble fiber from foods like oats, beans, and apples has been shown to promote the growth of beneficial bacteria like Bifidobacterium and Lactobacillus, essential for maintaining a healthy gut lining.

  2. Anti-Inflammatory Foods: Research in Nutrients (2020) highlights the anti-inflammatory effects of polyphenol-rich foods such as berries, green tea, and turmeric. Curcumin, the active compound in turmeric, has been studied extensively for its ability to inhibit inflammatory markers such as NF-kB and COX-2, which play a role in chronic disease.

  3. Herbs for Healing: Studies in Phytomedicine (2022) reveal that herbs like rosemary, thyme, and oregano possess antimicrobial and antioxidant properties. These herbs not only flavor food but also combat oxidative stress and support the immune system.

  4. Whole Foods and Longevity: The American Journal of Clinical Nutrition (2021) linked whole food-based diets with a decreased risk of chronic diseases, including cardiovascular disease and type 2 diabetes. Researchers found that higher intake of vegetables, nuts, and legumes is associated with improved metabolic health and reduced mortality.


    Key Principles of the General Healing Diet

    “Every time you eat or drink, you are either feeding disease or fighting it.” — Heather Morgan

    1. Nutrient Density: Prioritize foods packed with vitamins, minerals, and antioxidants. Dark leafy greens, nuts, seeds, and colorful vegetables take center stage. For example, spinach and kale are rich in magnesium, which supports nerve and muscle function.

    2. Anti-Inflammatory Ingredients: Incorporate omega-3-rich foods like salmon and walnuts, and spices like ginger and turmeric. Omega-3 fatty acids from fish and flaxseeds reduce the production of inflammatory eicosanoids and cytokines.

    3. Blood Sugar Balance: Focus on low-glycemic carbohydrates, healthy fats, and quality protein to prevent spikes in blood sugar levels. For instance, combining quinoa with avocado and grilled chicken can create a balanced meal that sustains energy.

    4. Gut Microbiome Support: Fermented foods like kefir, kimchi, and sauerkraut provide probiotics, while prebiotics from garlic, onions, and bananas feed healthy gut bacteria.

    5. Herbal Integration: Use herbs such as basil, cilantro, and dandelion to detoxify and support liver function. Dandelion root tea, for instance, is known to aid in digestion and bile production.

    6. Eliminating Toxins: Beyond avoiding ultra-processed foods, consider the broader sources of toxins in your environment. Conventionally farmed foods are often sprayed with glyphosate and other harmful pesticides, which have been linked to disruptions in gut health and increased cancer risk (Environmental Health Perspectives, 2021). Whenever possible, choose organic produce and pasture-raised meats to minimize exposure.

    7. Environmental and Household Toxins: The average household is inundated with chemical-laden products—from plastic food storage containers leaching endocrine-disrupting chemicals like BPA, to everyday items such as shampoos, body washes, and cleaning products containing harmful parabens, sulfates, and synthetic fragrances. Opt for glass storage containers, non-toxic cleaning products, and organic, chemical-free personal care items to reduce your toxin load.

    8. Factory Farming and Animal Welfare: Factory farming practices pose significant health and ethical concerns. Animals raised in these environments are often confined to small spaces, fed unnatural diets, and treated with antibiotics and growth hormones. This not only raises concerns about animal welfare but also introduces harmful substances into the human food chain. Antibiotics overuse contributes to antibiotic resistance, while growth hormones may disrupt endocrine systems in humans. Factory farming is also associated with significant environmental degradation, including water pollution and greenhouse gas emissions. By choosing sustainably raised, grass-fed, or free-range animal products, you not only support ethical farming practices but also reduce exposure to toxins and promote environmental sustainability.


    The Toxicity of Everyday Products

    “Detoxifying your life isn’t just about food—it’s about the air you breathe, the products you use, and the water you drink.” — Unknown

    Everyday exposure to environmental toxins extends far beyond the food we eat. Plastic products, personal care items, and household cleaning supplies are significant contributors to the toxic burden on our bodies.

    1. Plastics: Plastics used for food storage and packaging often leach harmful chemicals like bisphenol A (BPA) and phthalates, which act as endocrine disruptors. These chemicals can interfere with hormone balance, potentially leading to issues like reproductive health problems, metabolic disorders, and even cancer. Switching to glass or stainless steel containers is a simple way to reduce this exposure.

    2. Personal Care Products: Shampoos, soaps, makeup, and lotions often contain parabens, synthetic fragrances, and other harmful chemicals. Parabens have been linked to hormonal disruption, while synthetic fragrances often contain phthalates, which can exacerbate allergies and other sensitivities. Opting for organic or all-natural products free from these additives can significantly reduce toxin absorption through the skin.

    3. Cleaning Supplies: Many conventional cleaning products contain volatile organic compounds (VOCs), ammonia, and bleach, all of which can irritate the respiratory system and contribute to indoor air pollution. Choosing natural cleaning alternatives, such as vinegar and baking soda, or buying non-toxic, eco-friendly brands can greatly reduce exposure.


    Addressing Nutritional Deficiencies

    “You are what you absorb, not just what you eat.” — Unknown

    Common Deficiencies: Many individuals are deficient in essential nutrients such as vitamin D, magnesium, omega-3 fatty acids, and zinc due to poor dietary choices, soil depletion, and chronic stress. For example, the CDC reports that approximately 10% of Americans are vitamin D deficient, contributing to immune dysfunction and bone health issues.

    Targeting Deficiencies Through Diet: Incorporating nutrient-dense foods like fatty fish, eggs, seeds, nuts, and fortified plant milks can help combat these deficiencies. Dark leafy greens provide magnesium, while shellfish and legumes are excellent sources of zinc.

    Absorption Matters: Gut health plays a crucial role in nutrient absorption. Addressing gut inflammation through probiotics, bone broth, and anti-inflammatory foods ensures you maximize nutrient uptake.

Salt, Sodium, and Blood Pressure: Why the Real Story Is More About Insulin and Metabolic Health

From Villain to Vital NutrientFor decades, sodium was portrayed as a dietary villain blamed for high blood pressure and heart disease. Public health campaigns urged us to avoid salt. Yet modern science reveals a more nuanced truth. Sodium is essential—vital for fluid balance, muscle contraction, and nerve signaling. Too little is as dangerous as too much. Meanwhile, emerging evidence reveals that the real driver of hypertension isn’t sodium alone—it’s insulin resistance, poor potassium intake, and metabolic dysfunction.The Origins of the “Salt = Hypertension” MythThe notion of “salt causes hypertension” traces back to animal studies by Dahl in the 1970s, where high sodium raised blood pressure in salt-sensitive rats. Human data followed, leading to generalized anti-sodium recommendations.Salt sensitivity actually applies to a subset of people—estimated at 25–50%; many individuals exhibit minimal blood pressure changes regardless of sodium intake (salt-resistant) .Large observational studies like PURE (Prospective Urban Rural Epidemiology) found a J-shaped curve: very high sodium was harmful, but so was very low sodium intake. Cardiovascular risk was lowest in moderate intake ranges .Individual variability matters—kidney function, age, insulin resistance, and genetics significantly modify how sodium affects you.So, the blanket statement “salt causes hypertension” is outdated and overly simplistic.Insulin Resistance: The Hidden Driver of Sodium RetentionInsulin controls how your kidneys handle sodium. In hyperinsulinemia states, the kidneys retain more sodium, increasing blood volume and pressure .Additionally, insulin may activate the sympathetic nervous system, tightening blood vessels and further raising blood pressure .This implies many with hypertension are “insulin-sensitive” rather than “salt-sensitive.” Addressing insulin sensitivity—with diet, movement, sleep, and stress reduction—can impact blood pressure independently of sodium intake.Sodium + Potassium: The Balancing ActPotassium counters sodium. It helps the kidneys excrete excess sodium and relaxes blood vessels. Diets low in potassium, which are common in the Western diet, worsen sodium’s effects on blood pressure .Traditional diets rich in fruits, vegetables, beans, and tubers naturally provide this balance.The DASH diet (Dietary Approaches to Stop Hypertension) lowers blood pressure in part by emphasizing potassium-rich foods—even without extreme sodium restriction.How Much Sodium Do We Really Need?General Guidelines (Non-Training Days)The AHA recommends up to 2,300 mg/day (≈1 tsp salt), aiming toward 1,500 mg/day for those with hypertension .The PURE study suggests lowest cardiovascular risk with 3,000–5,000 mg/day, depending on potassium and metabolic health .Training Days / AthletesSweat can lose 500–2,000 mg sodium per liter. Endurance athletes, especially in heat, may need 3,500–5,500 mg/day or more.Guidance:90 min intense/hot: ~500–1,000 mg sodium/hour.Signs You’re Getting It WrongToo little sodium (relative to need):Dizziness, headaches, muscle crampsBrain fog, fatigue, nauseaFrequent urination with very clear urineIn extreme cases: hyponatremia—an emergencyToo much sodium (chronically):Elevated blood pressure in salt-sensitive individualsBloating, swelling (hands, ankles)Constant thirstThe Type of Salt Matters (But Not As Much As You Think)Your body cares about sodium, not crystal color—but the form of salt has context:Iodized table salt: Adds iodine (essential for thyroid health).Sea salt / Himalayan pink salt: Trace minerals present but negligible nutrition-wise; sodium per gram nearly identical to table salt.Kosher salt: Larger crystals, great for cooking; often lacks iodine.Electrolyte salts: Blend sodium with potassium and magnesium—useful for athletes and hot training days.Specialty salts may taste or look different, but they don’t alter sodium’s effect on blood pressure or physiology.Smarter Sodium StrategiesSalt whole foods—not processed ones. 70–80% of dietary sodium comes from packaged and restaurant foods, not your shaker.Boost potassium. Incorporate avocado, beans, leafy greens, yogurt, and squash.Control insulin. Prioritize exercise, protein-forward whole foods, sleep, and stress management for better sodium handling.Use the right salt for your iodine needs. If seafood isn’t in your diet, iodized salt is important.Personalize intake. Monitor blood pressure at home over 2–4 weeks as you adjust sodium and lifestyle.Sample Day FrameworksBalanced Rest DaySodium Targets & Strategy ~2,000 mg sodium totalBreakfastGreek yogurt + salted pumpkin seeds (~250 mg)LunchChicken salad with olives, feta, vinaigrette (~600 mg)SnackCottage cheese with cucumber (~400 mg)DinnerSalmon, roasted potatoes, green beans, pinch of sea salt (~750 mg)Hot Training Day~3,500 mg sodium totalPre-WorkoutWater + pinch of salt + half a banana (~200 mg)During TrainingElectrolyte drink (~1,000 mg sodium total)Post-Workout MealRice bowl with steak, salsa, avocado (~900 mg)DinnerSoupy stew with chicken and vegetables (~1,000 mg)SnacksPickles/olives if craving salt (~400 mg)FAQsQ: Does salt cause high blood pressure in everyone? No. Only 25–50% are salt-sensitive; insulin resistance, age, and low potassium often play larger roles .Q: Should I avoid all processed foods? Not necessarily—but since most sodium comes from processed sources, cooking at home gives you control.Q: Is Himalayan salt healthier? Not for sodium content. Its trace minerals are negligible. If iodized salt isn’t used, ensure iodine from seafood or dairy .The TakeawaySodium is essential, not evil.Insulin resistance and low potassium drive hypertension more than salt alone.Most people do well with 2,000–3,500 mg/day, though athletes and hot-weather exercisers may need more.Personalization beats one-size-fits-all.Prioritize whole foods, metabolic health, and mindful sodium intake.ReferencesSalt sensitivity estimates and individual variation in blood pressure responsePURE study findings on J-shaped sodium-risk curveInsulin’s effect on renal sodium retentionInsulin, sympathetic activation, and blood pressurePotassium’s sodium-excretion effect and guidelinesAHA sodium intake recommendationsNIH iodine guidelines for iodized saltSodium sources — processed vs home-cooked (widely reported estimates) …and based on prior evidence and dietary surveys.

Understanding SIBO: How It Starts and How to Reverse Its Effects

Small Intestinal Bacterial Overgrowth (SIBO) is a condition where bacteria from the colon overpopulate the small intestine, leading to bloating, gas, malnutrition, and a host of frustrating symptoms.1. What is SIBO—and How Does It Begin?The small intestine typically has very few bacteria, thanks to protective mechanisms like stomach acid, bile, digestive enzymes, and intestinal motility. But when these systems break down, bacteria can thrive where they shouldn’t.Protective barriers include gastric acid, bile, digestive enzymes, the migrating motor complex (MMC), intact ileocecal valve, and immune defenses (e.g., secretory IgA) PMC+15NCBI+15Dr Stavy Nikitopoulou+15.When they fail—due to low stomach acid, enzyme insufficiency, anatomical changes, autoimmune conditions, hypothyroidism, diabetes, scleroderma, IBS, or post-infectious gut damage—SIBO can take hold NCBI.Other common triggers include prior food poisoning, medication use (like PPIs or painkillers), and structural issues like surgeries or fistulas Health.2.

Cannabis & Your Brain: What the New Landmark Study Really Shows Published evidence (Feb 2025) has a lot of people talking: a large, carefully analyzed brain-imaging study reports that heavy cannabis use is linked with reduced brain activation during w

Published evidence (Feb 2025) has a lot of people talking: a large, carefully analyzed brain-imaging study reports that heavy cannabis use is linked with reduced brain activation during working-memory tasks—the kind of mental work you rely on to hold instructions in mind, follow a conversation, do mental math, or safely navigate a busy road. JAMA NetworkBelow, I’ll break down what the study did, what it found (and didn’t), what it may mean for women and young adults, and smart, practical takeaways you can use today.Key Takeaways (in plain English)In 1,003 young adults (ages 22–36), people who had used cannabis more than 1,000 times in their life (the study’s “heavy use” group) showed lower activation in key brain regions while doing working-memory tasks—even after excluding those who had recently used. JAMA NetworkMedia and university summaries note that about 63% of heavy lifetime users and about 68% of recent users showed reduced brain activity on the working-memory task. CU Anschutz NewsThe affected regions included the dorsolateral and dorsomedial prefrontal cortex and the anterior insula—areas that help you concentrate, plan, regulate emotions, and make decisions. These regions are dense in CB1 cannabinoid receptors, which THC binds to. JAMA NetworkCausation isn’t proven (the study is cross-sectional), and most other cognitive tasks in the study didn’t meet the strictest statistical threshold. Still, the working-memory result was robust after multiple-comparison corrections. JAMA NetworkRecent use was linked to poorer performance on several tasks (including working memory), and residual cognitive effects from cannabis can persist for 2–4 weeks after stopping—important if you’re about to take an exam, drive long distances, or do high-stakes work. JAMA NetworkWhat Makes This Study “Landmark”?Size & rigor. The research analyzed 1,003 young adults from the Human Connectome Project, using standardized fMRI tasks across seven cognitive domains (working memory, language, reward, motor, emotion, relational reasoning, theory of mind). It measured both lifetime exposure and recent use (via urine toxicology the day of scanning). Analyses adjusted for age, sex, education, income, alcohol, and nicotine. JAMA NetworkClear exposure groups. Participants were classified as heavy (>1,000 lifetime uses), moderate (10–999 uses), and non-users (1,000 uses” is self-reported; still, urine toxicology confirmed recent exposure status. JAMA NetworkAge window: Results in 22–36-year-olds may not generalize to older adults or teens. JAMA NetworkTask specificity: Working memory effects were strongest; other tasks didn’t meet strict thresholds after correction. JAMA NetworkPractical Guidance If You (or Your Teens) Use CannabisThis section is informational and not medical advice.Protect your working memory window. If you must perform cognitively demanding tasks (exams, major presentations, meticulous driving/navigation, high-risk jobs), abstain well in advance—think weeks, not days, especially if you’re a frequent user. JAMA NetworkWatch frequency & potency. The “heavy” pattern (>1,000 lifetime uses) is where the strongest association showed up. Higher-THC products likely increase risk; titrate down or take structured breaks if you choose to use. JAMA NetworkBe extra cautious if you’re under 25. With brains still developing, err on the side of less—and seek healthier sleep/anxiety strategies first (breathwork, morning light exposure, resistance training, omega-3-rich meals, magnesium glycinate as appropriate). National Institute on Drug AbuseFlag red-flags for psychosis risk. Family history of psychosis, early heavy use, and high-potency THC raise risk signals. Seek professional guidance; products with lower THC and/or higher CBD may reduce some risks, but this is not a guarantee. PMC Cycle breaks intentionally. If you’re a regular user, plan tolerance breaks and monitor cognition (focus, memory, task follow-through) during and after a 2–4 week pause. JAMA NetworkFor Women: Any Sex-Specific Data?In this dataset, the working-memory association didn’t differ by sex, although there was a sex interaction on a motor task (recent THC linked with lower activation in men, not women—one dataset, not definitive). We need female-focused studies on dose, hormones, and cycle phase to tailor guidance better. JAMA NetworkThe Bottom LineThe strongest, most conservative signal from the new large study is that heavy, long-term cannabis use is associated with dampened brain activation during working memory, centered in prefrontal and insula circuits. That’s the exact network you need for day-to-day mental performance. JAMA NetworkRecent use can also blunt performance—sometimes for weeks after stopping—so timing matters for safety and productivity. JAMA NetworkNot all cannabis exposure is equal: dose, frequency, age, THC potency, and product type likely determine risk. Some medical-use cohorts don’t show the same neural changes, underscoring the need for personalized, cautious approaches.
