Send us Fan Mail “I’m allergic” is the fastest way to get taken seriously at a restaurant, but it can also keep you stuck in confusion about what’s really happening in your body. I’m Teresa Christensen, a functional medicine certified health coach living with histamine intolerance, and I’m breaking down the real difference between true food allergies, food intolerances, and everyday food choices that get mislabeled as both. We start with the clearest line in the sand: an IgE-mediated food al...
Send us Fan Mail What if the flare you blamed on dinner wasn’t a food reaction at all, but a blood sugar swing that pushed your mast cells over the edge? We pull back the curtain on the hidden link between glucose variability, inflammation, and histamine symptoms—and why the path to calm often starts with steadier meals, not deeper restriction. First, we map the biology in plain language. Chronic high blood sugar fuels oxidative stress and advanced glycation end products, turning up cytokine...
Send us Fan Mail What if your body isn’t broken, but brilliant at surviving—and ready to learn safety? We unpack how epigenetics and nervous system regulation shape MCAS and histamine intolerance, showing why genes are not destiny and how daily choices flip the switches that guide inflammation and immune tone. We start by reframing the “Is MCAS genetic?” question. While rare mast cell diseases can be mutation-driven, most MCAS looks multifactorial: inherited tendencies meet environment, stre...
Send us Fan Mail What if relief from histamine intolerance comes not from avoiding every trigger, but from meeting the right ones in the right dose? We dig into the gentle art of hormesis—small, intentional stressors paired with real recovery—to help your body adapt, calm inflammation, and rebuild trust with food, movement, and daily life. Through a personal story of winter cold, sauna heat, and the surprising ease of a cool rinse, we unpack how temperature contrast, short fasting windows, an...
Send us Fan Mail Your body notices structural change before you do. A small shift in the spine can ripple through fascia, nerves, and organs, and the result might look like eased headaches, a heavier yawn, digestive changes, or a brief spike of anxiety hours later. We unpack how structure guides function and why these responses are messages worth decoding, not red flags to fear. With clear, nonjudgmental language and practical steps, we turn vague discomfort into a readable map you can use to...
Send us Fan Mail What if the real trigger isn’t the food on your plate, but the way it’s cooked? We dig into the hidden link between high-heat browning, advanced glycation end products (AGEs), oxidative stress, and the histamine symptoms that make your day feel unpredictable. Without fear or food rules, we break down how heat, time, and moisture change your body’s response and how small tweaks can rebuild trust with meals you already love. We start with flavor—because browning tastes great—a...
Send us Fan Mail When your body feels unpredictable and the answers don’t come fast enough, where do you place your trust? Teresa invites you into a quieter lane of healing—one that starts with belief, connection, and the gentle rituals that help the nervous system feel safe. Drawing on early memories of church pews, the hush of a campus chapel, and the stillness of snowy sunrise walks, she shares how spiritual grounding—religious or not—can soften fear and steady the mind when symptoms surge...
Send us Fan Mail Your tomato isn’t the problem—your histamine bucket might be. We dig into a persistent myth around organic produce and grass-fed meats: they don’t lower histamine in the food, but they can lower the overall stress on your body so you react less. With a clear, friendly breakdown of DAO versus HNMT, we connect the dots between pesticides, environmental load, and the internal histamine your tissues release when inflammation runs high. We explore the ripple effect that many wome...
Send us Fan Mail What if detox had nothing to do with juice cleanses and everything to do with feeling safe in your body? We take a clear-eyed look at the hidden sources that keep histamine symptoms flaring—heat plus plastic in the kitchen, nonstick fumes, synthetic fragrances, stale indoor air, and the emotional pressure of jobs and relationships that drain your energy. We start in the everyday places people overlook: oils and syrups stored in warm plastic, takeout containers popped into mi...
Send us Fan Mail What if your toughest histamine symptoms aren’t just about what’s on your plate, but what’s happening inside your cells? We dig into the surprising link between mitochondrial function and histamine intolerance, showing how your body’s energy system shapes reactions like headaches, flushing, itching, and brain fog—even when your diet looks dialed in. I break down how DAO and HNMT—the enzymes that clear histamine in the gut and inside cells—depend on energy, nutrients, and ant...
Send us Fan Mail We explore how the fall time change disrupts circadian rhythm and why women with histamine intolerance often feel foggy, wired, and fatigued. We share light-based strategies, gentle movement, hydration, and steady meals to steady mood and energy and reframe the season as a reset. • why the brain follows light, not clocks • how time change triggers fatigue, mood dips, brain fog, and flares • light therapy lamps and morning sunlight as anchors • benefits of brief, gentle movem...
Send us Fan Mail What if power isn’t about hitting 100%—but about staying plugged into what gives you energy, confidence, and calm? Teresa opens up about a raw, unforgettable moment of feeling “battery exhausted,” then walks through the simple, steady practices that rebuilt trust with her body and made daily life with histamine intolerance feel possible again. We explore a clear framework for recharging: meal planning that removes fear and decision fatigue, sleep routines that stabilize hist...
Send us Fan Mail Your body isn’t confused—you’re watching a delicate tug-of-war between rising estrogen, steadying progesterone, and mast cells that decide how loudly histamine speaks. We unpack that push–pull with clear, compassionate guidance so you can tell the difference between “just pregnancy” and histamine overload, and make small choices that add up to big relief. From first-trimester queasiness through late-term flushing, we explain how immune recalibration shapes symptoms, why DAO a...
Send us Fan Mail Stepping away from medication dependence doesn't happen overnight. For years, antihistamines were my constant companions—seven different prescriptions daily that I believed were essential to my survival with histamine intolerance and mast cell activation syndrome. My medicine cabinet told the story: H1s, H2s, PPIs, asthma inhalers, eye drops, and nasal sprays, each addressing different symptoms of the same underlying condition. When my allergist announced his retirement, I f...
Send us Fan Mail The mysterious connection between perimenopause and histamine intolerance finally explained! If you've wondered why your perimenopause symptoms feel more intense than what friends describe, this episode reveals the hidden mechanism making your experience uniquely challenging. Perimenopause isn't the steady hormone decline many expect—it's a rollercoaster where estrogen spikes trigger mast cells to release histamine while simultaneously reducing your body's ability to break i...
Send us Fan Mail Ever found yourself wide awake at 3 AM, itchy and restless, wondering why your body seems to sabotage your sleep? The connection between histamine intolerance and disrupted sleep patterns runs deeper than most realize. Sleep isn't just about rest—it's a foundational element of histamine regulation. During quality sleep, your brain undergoes a crucial "rinse cycle" called glymphatic flow, washing away inflammatory compounds and resetting your system. For those of us navigatin...
Send us Fan Mail Ever wondered why your symptoms seem to flare right before your period? The answer lies in the fascinating and often overlooked connection between female hormones and histamine intolerance. Women are twice as likely to suffer from histamine-related issues compared to men, and it's not by chance. Your body's natural hormone fluctuations create a perfect storm for histamine sensitivity. When estrogen rises before ovulation and menstruation, it activates mast cells throug...
Send us Fan Mail Mysterious skin reactions happen to many women with histamine intolerance, but the source often remains elusive. Through years of painful trial and error, I discovered a common culprit lurking in countless everyday items: latex. What began as unexplained "burns" from ordinary bandages evolved into a broader understanding of how this ubiquitous material was triggering my histamine system. The detective work started when bandages left my skin inflamed and irritated for days. L...
Send us Fan Mail When the mercury rises, those of us with histamine intolerance face unique challenges. Recording this episode during a brutal Midwest heat wave without air conditioning gave me a visceral reminder of how temperature extremes can wreak havoc on our sensitive systems. Heat stress triggers mast cell degranulation and histamine release, causing blood vessels to dilate and creating a cascade of symptoms many of us know all too well: swelling in the extremities, debilitating heada...
Send us Fan Mail Have you ever felt something was wrong with your body long before any test could confirm it? That gut feeling isn't just intuition—it's your body's intelligence speaking directly to you. When fire ants attacked me during what should have been a relaxing day in South Beach, my body sounded an alarm I couldn't ignore. Within minutes, my hands swelled, my legs failed, and I lost consciousness in the park grass. That terrifying experience with anaphylaxis completely transf...
