Toxin Binders and Cellular Health: What You Need to Know Before Detox

If you've ever sat across from a child who will only eat five foods—and watched their parents' exhaustion and guilt—you know this isn't just a phase. As a functional registered dietitian who works primarily with Spanish-speaking families raising children on the autism spectrum, I see this every single week. And what I've come to understand, both clinically and through the science, is that extreme food selectivity in neurodivergent children may be influenced by what’s happening beneath the surface, including at the cellular level.

The Body Before the Behavior

When a child with autism refuses most foods, the conventional response is behavioral therapy. And while therapeutic support absolutely has its place, functional nutrition approaches food aversion from a different angle. We want to know what is happening inside the body that makes eating so overwhelming. What's the root cause of this food refusal?

A 2025 study by Mora et al., published in Children (Basel), examined food selectivity and sensory profiles in children with ASD in Chile. They found that food selectivity is strongly associated with sensory hypersensitivity—particularly in the oral, social-emotional, and somatic domains. Textured foods were a barrier for 78% of children, and colorful foods for 53%. But here's the science we want to break down: sensory processing is both neurological and cellular.

How Mitochondrial Dysfunction Leads to Overwhelmed Children

Mitochondria are the energy producers of every cell in the body—including neurons. When mitochondrial function is compromised, the nervous system lacks the fuel it needs to regulate sensory input. The brain is easily overwhelmed, so food (texture, smell, taste, and color) becomes a trigger for big emotions. 

One study analyzed data from hundreds of children and found that mitochondrial dysfunction is up to 500 times higher in ASD patients. More recently, a 2024 systematic review and meta-analysis found that mitochondrial biomarker abnormalities—including elevated lactate and pyruvate—are present across a broad spectrum of children with ASD, not just those with a formal mitochondrial disease diagnosis.

This matters for how we think about (and treat) picky eating. A child who is mitochondrially stressed is a child whose entire nervous system is running on low battery—and food, with all its sensory demands, becomes one more input the system cannot handle.

The Gut–Brain Connection We Can't Ignore

Unfortunately, food sensitivity may worsen mitochondrial function. Highly restricted diets eventually lead to lower gut microbial diversity, which can create a snowball effect.  

Recent autism research found that 55% of these children with autism also had gastrointestinal symptoms and gut dysbiosis. According to the study, interventions targeting the gut microbiota produced measurable improvements in both GI and behavioral outcomes. This is consistent with research suggesting the gut and brain are in ongoing communication.

Another large human study found that the restricted dietary preferences characteristic of ASD directly reduce microbial diversity. The selectivity feeds the dysbiosis, and the dysbiosis feeds the selectivity. It becomes a self-reinforcing cycle that shows up at meal times.

Gut dysbiosis in ASD is also associated with increased intestinal permeability—commonly referred to as "leaky gut"—which allows inflammatory signals to reach the brain, potentially exacerbating both sensory and behavioral symptoms.

The Real Nutritional Cost of a Five-Food Diet

The downstream consequences of extreme food selectivity are significant. In 2023,  scientists documented cases of scurvy re-emerging in children with ASD whose diets are so restricted that vitamin C intake falls to critically low levels. This is a signal of how deep the nutritional gaps can go.

When essential fatty acids, phospholipids, and key micronutrients are chronically insufficient, cell membrane integrity suffers. And when cell membranes are compromised, mitochondrial function declines further—closing the loop on a cycle that begins at the table and reverberates throughout the body.

Where Cell Membrane Health Fits In

This is where we bring phospholipids into the conversation.

Phosphatidylcholine (PC) is the most abundant phospholipid in mammalian cell membranes, and research shows that the PC-to-phosphatidylethanolamine ratio in mitochondrial membranes plays a direct role in energy production. When this ratio is off, cellular energy output is affected.

Additionally, long-chain polyunsaturated fatty acids like DHA are critical for neurodevelopment. One study found that reduced bioavailability of n-3 PUFAs during development is linked to neurodevelopmental conditions including ASD and ADHD.

In my practice, supporting cell membrane integrity is one of the foundational steps I take with neurodivergent children. BodyBio PC is one of the tools I reach for in this context—it provides a concentrated source of phosphatidylcholine that may help support membrane structure, mitochondrial function, and the body's natural detoxification processes. I use it as part of a broader, individualized lifestyle and nutrition protocol, always alongside dietary changes and gut support.

BodyBio Balance Oil is the other foundational product in my basic protocol, providing omega-6 and omega-3 fatty acids in a targeted ratio. Balance Oil can be easily incorporated into familiar foods or drinks. For a child who already enjoys a chocolate protein shake or smoothie, adding Balance Oil to that familiar food can be a practical way to introduce essential fatty acids without creating another major sensory hurdle.

Don’t Overlook Mineral Balance 

Another important piece of the picky-eating puzzle is mineral balance. When a child’s diet becomes highly restricted, we often focus on calories, protein, and vitamins—but minerals can be just as important, particularly when it comes to taste, texture, and nervous system regulation. 

Zinc is one mineral I pay particular attention to. Inadequate zinc intake or status can affect taste perception and appetite, which may make food acceptance even more difficult for a child who is already sensitive to certain flavors and textures.

Magnesium, potassium, and other minerals and electrolytes are also important because of their roles in normal nervous system and cellular function. In my clinical experience, addressing mineral intake can be an important foundational step for children eating a very limited range of foods. 

For families who need broader mineral support, BodyBio ReMineralize is one option I use in practice. With particularly sensitive children, I prefer to introduce mineral support gradually rather than starting with a full serving. For example, I may begin with just 1–2 drops of ReMineralize in a glass of filtered water two to three times per day and gradually increase the amount based on the child’s individual needs and tolerance. 

A Whole-Body, Whole-Family Approach

The families I work with are navigating a complex diagnosis in a healthcare system that often doesn't speak their language, and they need more than an approved food list. They need a framework that makes sense of why their child eats the way they do and gives them concrete, culturally relevant steps that target the root cause.

That framework starts by recognizing that picky eating in neurodivergent children doesn't always come down to willpower, parenting failures, or behavioral quirks. Instead, the mitochondria, gut, and cell membranes may be signaling that the body needs foundational care.

In my clinical experience, when nutrient gaps are addressed as part of a broader plan, some families report more flexibility around new foods over time. Children who once refused entire food groups begin to engage with new textures. Mealtimes become less of a battleground. Parents begin to breathe again.

But getting there doesn't require changing everything at once. The goal isn't to overwhelm a child—or their parents—with a long list of supplements. It is to identify nutritional gaps, introduce support gradually, and work within the child's existing sensory comfort zone. Minerals, essential fatty acids, phospholipids, gut health, and overall nutrient adequacy are all pieces of the same larger picture.

For parents, this can also mean shifting the question from “How do I get my child to eat this food?” to “What might be making this food so difficult for my child in the first place?” When we start there, we can support the child from the inside out while continuing to work toward a more varied and nourishing diet.

That's the power of starting at the cell.

As the long, warm days of summer begin to wind down, many of us are still trying to soak up the last moments of the season: hiking, gardening, walking outside, traveling, and spending more time in nature. But with that time outdoors comes something many people do not think about until it happens: tick exposure, whether the bite is seen or never noticed at all.

Tick-borne illness can be subtle in the beginning. A person may feel like they have a summer flu, a few days of fatigue, a headache, body aches, swollen glands, or vague joint pain, and then feel well enough to move on. Because the early symptoms can be nonspecific, many people never connect them to a tick bite.

Lyme Disease Is Only One Part of the Tick-Borne Picture

Lyme disease is a bacterial infection caused by Borrelia bacteria and spread through the bite of an infected blacklegged tick, often called a deer tick. In the United States, Lyme disease most commonly refers to infection with Borrelia burgdorferi. However, other Borrelia species and related tick-borne infections also exist, which is one reason a thoughtful exposure history and a physician who understands the broader tick-borne landscape can be so important.

Lyme is not the only illness clinicians consider after tick exposure. Depending on geography, symptoms, immune status, and the type of tick involved, evaluation may also include other tick-borne or vector-associated infections such as babesiosis, anaplasmosis, ehrlichiosis, Rocky Mountain spotted fever, Powassan virus, and, when clinically appropriate, Bartonella or other co-factors.

Lyme Disease Acute and Chronic Symptoms

Early Lyme symptoms may include fatigue, fever, headache, body aches, swollen lymph nodes, and sometimes an expanding rash. The classic target-like or “bull’s-eye” rash is well known, but not everyone develops it, and not everyone notices it. That is one of the reasons Lyme disease can be missed in the early stages.

When Lyme disease is not recognized and treated appropriately, it can progress beyond the initial flu-like phase and may affect the joints, nervous system, heart, and overall energy regulation. This is why so many patients associate Lyme and tick-borne illness with fatigue, brain fog, pain, migratory symptoms, inflammation, and a sense that their body no longer feels like their own.

In my own practice, I have seen many patients with persistent joint pain, neurologic symptoms, or unexplained inflammatory patterns whose tick-borne evaluation had been delayed or never considered. Not every orthopedic or neurologic symptom is infectious, of course. But persistent, unexplained symptoms deserve a complete history, appropriate testing, and a clinician willing to look at the whole picture.

My Personal Experience with Lyme

I have personally had Lyme disease. At the time I was diagnosed, nothing dramatic was happening. I was exhausted at night, but I had two young children, so that seemed easy to explain. I had joint pain that came and went, but it did not stop me from exercising. I also had a history of headaches that I had learned to manage.

After treatment, which took about a month, those symptoms resolved and have not returned. That experience shaped the way I listen to patients. Sometimes the body whispers before it screams. The earlier we listen, the more opportunity we have to intervene before the system becomes deeply dysregulated.

The Cellular Terrain Matters

After more than 20 years of treating complex chronic illness, including thousands of patients with Lyme and tick-borne illness, one lesson has become very clear to me: recovery is not only about fighting a pathogen. It is also about restoring the terrain.

The body is made of trillions of cells, and each cell is surrounded by a membrane composed largely of specialized fats called phospholipids. These membranes are not passive walls. They help regulate what enters and leaves the cell, how cells communicate, how inflammatory signals are transmitted, and how mitochondria function.

I often describe DNA as the hard drive and the cell membrane as the keyboard. If the hard drive contains the instructions but the keyboard is damaged, the message can become distorted. In the same way, when cell membranes are stressed, inflamed, oxidized, or depleted, the body’s communication system can become less efficient.

Borrelia and other chronic infections can interact with the body’s lipid and membrane systems in complex ways. In clinical practice, this helps explain why some patients experience neurologic symptoms, brain fog, nerve irritation, hypersensitivity, and nonspecific symptoms even when the question is no longer simply, “Is there active infection?” The deeper question becomes: “How do we repair the system that has been under stress?”

From Fighting Infection to Rebuilding the Body

A great deal of the conversation around Lyme disease focuses on killing or suppressing the infection. That can be necessary. But if we only focus on the pathogen and ignore the terrain - the cells, membranes, mitochondria, nervous system, immune system, detoxification pathways, and inflammatory signaling — then full recovery may remain incomplete.

I often compare it to a battlefield. Once the battle is over, even if the offenders are gone, the field still needs to be cleaned, repaired, and restored. The same is true of the body. The body needs support. It needs nourishment. It needs the right building blocks to restore balance.

This is where phospholipids and balanced essential fatty acids can become a valuable part of a comprehensive recovery and maintenance plan.

The Role of Phospholipids in Cellular Support

BodyBio PC is one of the foundational supplements I use for cellular support. It is a full-spectrum phospholipid complex that provides essential lipids such as phosphatidylcholine and phosphatidylethanolamine, which help support healthy cell membrane structure and function.

Phospholipids are essential for maintaining strong, fluid, responsive cell membranes. We can obtain some phospholipids through foods such as egg yolks and sunflower seeds, but the body’s need may be higher after prolonged illness, inflammation, oxidative stress, or cellular depletion.

BodyBio Balance Oil is another important tool because it provides a thoughtful balance of omega-6 and omega-3 essential fatty acids. Omega-6 is often misunderstood, but certain omega-6 fatty acids are necessary for healthy membrane function and mitochondrial support, including the production and maintenance of cardiolipin, a key phospholipid found in mitochondrial membranes.

Healthy membranes support clearer cellular communication. Clearer cellular communication supports immune balance, nervous system resilience, mental clarity, mitochondrial function, and the body’s ability to return to homeostasis.

Reclaiming Vitality

Living with the lingering effects of Lyme or tick-borne illness can feel isolating. Fatigue and brain fog can make you feel disconnected from your body, your routines, and even your sense of self. Patients often say, “I just do not feel like myself.” I understand that. I have lived it, and I have treated it for decades.

But your body is not broken. It is asking for support.

As summer winds down, take a moment to listen to what your body may be asking for. If you have had a tick bite, unexplained flu-like symptoms, a new rash, migratory joint pain, neurologic symptoms, or lingering fatigue, do not dismiss it. Seek evaluation from a clinician who understands Lyme disease, tick-borne illness, and the importance of rebuilding the whole system.

True health is not simply the absence of illness. It is the return of vitality, clarity, energy, and the feeling of being fully present in your own body again.

In my practice, BodyBio PC and Balance Oil are part of the cellular support and maintenance programs I use to help patients rebuild resilience at every stage of life.* Because healing is not only about what we remove, it is also about what we restore.
