Gut Science 101: Why Food Isn’t the Problem

When your digestive system is working well, you should be able to tolerate a wide variety of foods. If everything makes you feel bloated, foggy, or tired, something upstream usually needs healing.

Here are the most common root causes I see in clients:

1. Low Stomach Acid

Stomach acid is the first step in digestion.
If it’s too low (very common in stressed, postpartum, or chronically dieting women), food doesn’t break down properly—leading to bloating, reflux, and nutrient deficiencies.

2. Insufficient Digestive Enzymes

Enzymes help break down protein, fats, and carbs.
If you’re low on enzymes, foods like meat, dairy, and beans can feel heavy or uncomfortable—not because they’re bad, but because your body needs more support to digest them.

3. Gut Microbiome Imbalance (Dysbiosis or SIBO)

Your gut bacteria help ferment and break down fiber and complex carbs.
When the microbiome is off, foods like onions, garlic, broccoli, or fruit can cause gas, bloating, or brain fog.

4. Inflammation or “Leaky Gut”

Chronic stress, ultra-processed foods, infections, or antibiotics can irritate the gut lining.
This can make your body react to foods that used to feel totally fine.

5. Stress & Nervous System Dysregulation

Digestion literally shuts down when you’re in fight-or-flight.
Busy mom life, trauma, under-eating, and poor sleep can all reduce digestive capacity—no matter how “clean” you eat.



The Goal Isn’t to Avoid Foods Forever

The goal is to heal your gut so you can enjoy food without symptoms.

Elimination diets simply reduce the digestive load while we rebuild your gut’s ability to digest, absorb, and tolerate a wide range of foods again.
