I recently learned that there’s a day called National Dessert Day. Honestly, I don’t think most people even know it exists. But when I heard about it, my first thought wasn’t, “Yum, let’s celebrate.” It was, “How many people would actually be afraid to celebrate this?”

We’ve been programmed to believe dessert is bad. Sugar causes disease. Certain ingredients are dangerous. Eat the “wrong” thing and you’ll inflame your body, damage your gut, feed illness, or set yourself back in your healing. That’s the message coming at you from every direction, all day long.

Then you add chronic symptoms and food sensitivities on top of that. Now you’re not just hearing that sugar, gluten, dairy, or seed oils are “bad.” You’re also living with the fear of how your body might react if you eat them. For a lot of people, National Dessert Day isn’t fun or cute. It’s just another reminder of what they can’t eat and how fragile their body feels.

How Fear Of Food Quietly Takes Over Your Life

Whether you have symptoms or not, fear around food is everywhere. Open your phone and you’ll see it: “Don’t eat sugar. Don’t eat dairy. Don’t eat gluten. Don’t eat carbs. Don’t eat seed oils. Don’t eat processed food.” The list never ends, and half of it contradicts itself. One person says never eat meat, the next tells you meat should be most of your diet. So you’re not starting from a neutral place with food. You’re starting from confusion and fear.

“When every bite feels like a test, your nervous system never really gets to relax around food.”

That programming usually starts early. Maybe you grew up hearing food called good, bad, healthy, unhealthy, or fattening. Maybe you watched adults diet, restrict, count calories, or talk about how guilty they felt after eating certain things. So long before you ever had chronic symptoms, you already had plenty of reasons to believe that food could harm your body and that you needed to be careful with it.

Then you start having health issues, and it feels natural to look at food as the bad guy. You take out one thing to see if it helps. Maybe you remove gluten or dairy. Your symptoms don’t go away, so you go to a practitioner who tells you to remove something else. Because you feel a tiny bit better, or you’re desperate, you double down. You get a food sensitivity test. The results come back and suddenly you’re “sensitive” to 20 different foods. Now your safe list fits on two hands, maybe less.

This is the domino effect I see with so many of my Mind Body Rewire clients. Eating, which is supposed to nourish you and bring you together with people, becomes miserable.

  • You can’t go to a restaurant without studying the menu days ahead.

  • You worry about traveling because you don’t know what you’ll be able to eat.

  • You bring your own food to gatherings or skip them completely.

  • You don’t trust anything you didn’t prepare yourself.

Your safe food list keeps getting smaller while your fear keeps getting bigger.

💡 Pro Tip: If planning what you’ll eat takes more energy than the actual meal, it’s a sign food fear is running the show—not you.

What Food Fear Really Teaches Your Body

The biggest problem with food fear isn’t just the limited diet. It’s what it teaches you about your body. Every meal becomes another time to scan, analyze, and search for something wrong. If your symptoms increase, you look back and try to figure out what you ate. If you feel better, you credit the restriction and become even more afraid to step outside of it. Either way, food stays in control and your body feels weaker and more unpredictable in your mind.

You may believe all this attention is protecting you. It feels like you’re being responsible: finding the perfect diet, identifying every trigger, following every rule. But I want you to really look at what it’s giving you. If more control were healing the problem, you’d feel safer as your diet got more restricted. In my experience, the opposite usually happens. The more foods someone removes, the more afraid they become of making a mistake. One “wrong” bite feels like a threat.

When symptoms show up, you wonder if you ate something wrong, ate too much, combined foods incorrectly, or weren’t careful enough. So you go to an even stricter plan. And at some point, you have to ask yourself some hard questions:

  • Do I trust my body more than when I started all this?

  • Do I actually have fewer symptoms?

  • Do I have more freedom, or just more rules and a smaller life?

This isn’t about judging the choices you’ve made. You were trying to help yourself with the information you had. But if this approach isn’t taking you toward healing, it’s okay to question it. Healing should not make your world smaller. The whole point is to get your life back, not trade symptoms for a prison of food rules.

Food Sensitivities, Subconscious Tracks, And Why Avoiding Isn’t The Answer

I want to make something really clear: food sensitivities are 100% real. If you eat something and experience bloating, pain, digestive issues, skin reactions, fatigue, or any other symptom, I’m not saying you’re imagining it. The reaction is real. I also want to be very clear that I’m not talking about diagnosed food allergies or medical conditions that truly require you to avoid certain foods. Those are different conversations and those boundaries matter.

What I’m talking about are the sensitivities that develop or multiply over time. The foods you used to eat that now suddenly seem to cause symptoms. The long list of “I can’t eat that anymore” that keeps growing. In my work and in my own life, I’ve seen that there are subconscious tracks connected to those sensitivity reactions. That means the food itself is not the core problem. The subconscious is. This is true for food sensitivities, chemical sensitivities, and a lot of other “I react to everything” patterns I see in clients.

Your subconscious learns through association. It connects what was happening around you with what your body was experiencing at the time. A food can become linked to a stressful experience, an illness, a symptom, or simply the fear that something bad will happen when you eat it.

  • Maybe you ate that food during a period of high stress.

  • Maybe you happened to have a symptom after eating it once and your brain connected the two.

  • Maybe a practitioner or a test told you the food was a problem, and from that moment on you expected a reaction every time you ate it.

Often, you don’t even know you “have” a sensitivity until a test tells you. Then, because you’re aware of it, you start expecting a reaction. You brace yourself. You scan your body. You interpret every sensation through that lens. That expectation and fear reinforce the subconscious track. The more you fear the food, tense up before eating it, and monitor yourself afterwards, the stronger that track becomes. You’re teaching your system, “This is dangerous. Watch out.”

Avoidance may shrink your symptom list on paper, but it often shrinks your whole life along with it.

This is why simply removing the food doesn’t truly resolve the sensitivity. Yes, your reaction might seem to “go away,” but only because you’re avoiding the track. If you bring the food back without changing that subconscious pattern, your body responds the same way. So when people say, “Well, removing foods resolved my issue,” what often actually happened is their world just got smaller, and they never addressed what was driving the reaction in the first place.

💡 Pro Tip: At Mind Body Rewire, we don’t ask, “What else do you need to cut out?” We ask, “What did your subconscious learn to fear—and how can we safely retrain it?”

Why Fear Is The Glue (And What I See In My Clients)

In my Mind Body Rewire program, I’ve watched people come in reacting to almost everything they eat. Some are down to two foods. Two. And I’ve watched those same people bring back any food they want before they finish the program. Not by forcing themselves to eat something while they’re terrified, but by changing what’s driving the reaction in the first place: the fear and the subconscious tracks connected to it.

From what I’ve seen again and again, fear is the glue. If you never address the fear, all the work you do for the symptom doesn’t really stick, because fear is still running the show. So the process I use with clients starts with fear. You work on the fear, you work on the subconscious tracks attached to the symptom and the food reactions, and then you retrain your subconscious that the food is safe. After that, you can eat the food. That’s the process. Simple to describe, not always quick, but it works over and over in the people I work with.

To me, your current sensitivities are not a life sentence. Your subconscious learned an association, and what it learned can be changed. I’m not promising anything to you personally; I’m sharing what I’ve seen consistently with the people who come into my world and do this work. There’s also the mental load to consider: the label reading, planning, tracking, preparing separate meals, analyzing every reaction. Even when you’re not eating, you’re thinking about food. Over time, it can quietly become part of your identity. You stop seeing yourself as someone experiencing a sensitivity and start believing you are someone whose body can’t handle anything.

That’s not a small shift. That belief shapes every choice you make. And again, healing should not make your world smaller. The point of healing is for your world to get bigger, not for you to be scared of your next meal or skip out on your life because of it.

📌 Key Takeaway: Fear holds the entire pattern together. When you soften the fear, your body finally has room to respond differently.

My Own Beliefs About Food (And How They Changed)

Where I stand on food today is very different from where I used to be. I don’t believe food causes disease or chronic symptoms. In my view, symptoms are biological adaptations for survival, not punishment for eating the “wrong” thing. I know that challenges a lot of what you hear in the wellness world. It challenged me, too, because I didn’t always believe this.

Your body is not out to punish you for eating a slice of cake. It’s trying to protect you based on what it’s learned.

When I had my wellness center, I was terrified of sugar. I taught people how bad it was. I wasn’t trying to scare anyone; I truly believed I was helping based on what I knew at the time. But here’s what happens when you’re constantly told that sugar feeds disease, causes inflammation, and prevents healing: sugar stops being an ingredient. It becomes a threat. And you can swap sugar for gluten, dairy, seed oils, whatever the current villain is. The pattern is the same.

So you eat a piece of cake or a piece of bread and immediately think about what it might be doing inside your body. If you feel anything afterwards, you blame the cake or the bread. That reaction becomes more “proof” that the food is bad and that you need to be even more careful. When I stepped into the belief that food does not cause disease or symptoms, I was finally able to fully embrace eating anything. And that freedom feels frickin’ amazing, I’m not gonna lie.

I can eat cake without believing it’s harming me. I can go to a restaurant, enjoy a vacation, or eat what someone else prepared without being afraid I’ll “pay for it” later. That doesn’t mean I think eating cake all day is a great idea. For me, it’s everything within reason. I don’t see food as good or bad. I look at what kind of fuel it’s going to give me. Some foods give me more energy and nutrients. Some are simply enjoyable. Food also gives us pleasure, connection, tradition, and shared moments with people we love.

If I ate cake all day, I probably wouldn’t feel my best because it wouldn’t give my body all the fuel it needs. That’s very different from believing one piece of cake is bad and could cause disease in my body. I can choose foods that support me without being afraid of the foods I eat just because they’re fun or comforting. There’s no guilt, no need to “make up for it” later, and no belief that I’ve done something wrong. That’s the kind of relationship with food I want for you. You can care about what you eat without being controlled by it.

💡 Pro Tip: Try shifting from “Is this good or bad?” to “How does this fuel me—physically, emotionally, and socially?” The answer is often much kinder and more truthful.

Becoming Aware Of The Pattern (And A Question To Sit With)

If food has become your enemy—because of sensitivities or just general fear based on everything you’ve been told—I’m not asking you to go force yourself to eat all the things from a place of panic. The first step is to become aware of the entire pattern, not just the food and the reaction. Start noticing what you tell yourself before you eat. What do you expect the food to do? Where did that belief come from? Was it your own experience? Something you’ve heard over and over? A practitioner? A test result?

Then look at what you do after you eat. Do you immediately start checking for a reaction? How long do you monitor yourself? Do you automatically connect every sensation to the food? You can notice a symptom without turning it into another permanent restriction. Just start being an observer of you—of what you’re telling yourself before and after you eat. Awareness is the first step. Then you have to change the behaviors that keep reinforcing the fear. If you still approach every meal expecting danger and scanning your body afterwards, you’re teaching your subconscious the same pattern again and again.

📌 Key Takeaway: Awareness + different choices = new subconscious tracks. You can’t bully your way out of food fear, but you can gently retrain it.

If you’re currently down to a small number of foods, the thought of changing any of this might feel overwhelming. I get that. But where you are now is not proof of where you’ll always be. Your reactions can be real without becoming your identity. Your current safe food list does not have to be a life sentence. I want you to imagine going to a restaurant and choosing what actually sounds good. Imagine traveling without planning the entire trip around food. Imagine eating a piece of cake without spending the rest of the day waiting for something bad to happen or beating yourself up for it.

Imagine food just becoming food again. Not a test. Not a threat. Not good or bad. Just food. And if your first response to every symptom has been, “What do I need to cut out next?” I want you to pause and ask yourself a different question:

What if food is not the whole story here?

What if the fear, the body scanning, and the subconscious tracks connected to your reactions are also part of this cycle? You don’t need to blame yourself for the choices you’ve made. You made them because you were trying to protect yourself. Now that you can see more of the picture, you get to choose something different. Healing should not leave you afraid of the very thing your body needs to live. It shouldn’t keep you sitting out of dinners, holidays, travel, and moments with the people you love. Your subconscious can learn something new. Your relationship with food can change. And your world can become bigger again.

Wish healing didn’t feel so complicated?

With so much conflicting advice and another diet, tool, or protocol always being recommended—it’s easy for healing to become a full-time job. Especially when no one has taught you your body's language or how to use it to build a clear healing strategy.

Healing doesn’t have to be as complicated as you’ve been led to believe.

For the past 10 years, we’ve helped thousands of people resolve chronic symptoms by focusing on one thing: subconscious patterns.

In MBR, we focus on three core patterns that interrupt healing. Understanding these patterns helps you make sense of what your chronic symptoms are communicating—and gives you a clear place to focus your effort.

That’s what I’ll teach you inside the 5-day Breaking the Symptom Cycle Challenge.

Discover the three patterns and leave with a clear healing strategy—so you can stop pouring time and energy into everything and know what actually moves the needle.

Its time to make healing simple.
