Identifying food intolerances

Somewhere along the way, you learned to override your body. To push through the after-lunch fog, to explain away the bloating, to treat discomfort as background noise. So let's slow down here, because the reactions you've been ignoring aren't random. They're data. Your gut has been keeping notes, and this lesson is about learning to read them.

A food intolerance isn't the same as a food allergy. An allergy is an immediate immune response — fast, sometimes dramatic. An intolerance is quieter and more delayed: your body struggles to fully break down or tolerate a food, and the fallout shows up hours or even a day or two later. That lag is exactly why intolerances are so easy to miss. You blame the afternoon slump on your workload, not on breakfast.

What an intolerance actually feels like

Intolerance symptoms are often nonspecific, which is part of why they get dismissed. Common signals include:

• Bloating or a visibly distended belly a few hours after eating
• Fatigue or brain fog that arrives after meals
• Loose stools, constipation, or unpredictable digestion
• Headaches, joint achiness, or skin flare-ups
• A racing or unsettled feeling — your nervous system reading the disturbance as a low-grade alarm

The usual suspects are gluten, dairy (lactose), eggs, soy, corn, and high-FODMAP foods like onion, garlic, and certain legumes. But your suspects are yours. This isn't a list to fear — it's a starting point for curiosity.

How to test without guessing

The gold standard here isn't expensive lab work. It's the elimination and reintroduction protocol — and it's the closest thing we have to a conversation with your gut.

Here's the shape of it:

1. Remove the most common trigger foods for two to three weeks. Long enough for inflammation to settle and your baseline to emerge.
2. Notice how you feel. Sleep, energy, digestion, mood. This is where a simple symptom journal earns its keep — because you can't reintroduce well if you never established a clear "before."
3. Reintroduce one food at a time, every two to three days, and watch for a response. One food. One window. Otherwise the data gets muddy.

This is deliberate work, not a crash cleanse. You're not punishing your body — you're listening to it. If elimination feels overwhelming or you have a history of restrictive eating, this is a moment to move slowly and, ideally, with a practitioner. Restriction is not the goal here. Understanding is.

A gentle 3-day microbiome-friendly reset

While you're gathering information, you can also give your gut lining and its bacterial community a calmer environment. Think of these three days as a soft landing, not a detox.

Day 1 — soothe. Simple, cooked, warm foods. A gentle soup or bone or vegetable broth, well-cooked white rice or quinoa, steamed zucchini and carrots, a piece of white fish or a soft-cooked egg if you tolerate it. Cooked over raw eases the digestive load.

Day 2 — nourish. Add colour and easy plants. Roasted root vegetables, a small serving of ripe banana, blueberries, olive oil, herbs like ginger and parsley. Keep portions moderate and chew slowly.

Day 3 — diversify. Gently expand your plant variety — leafy greens, a modest amount of cooked lentils if they sit well, fermented foods in small amounts (a spoonful of sauerkraut, a little plain kefir if dairy is tolerated).

Small, warm, unhurried meals. Eat when your body is calm — not standing at the counter answering messages.

A word on prebiotics and binders

Two tools you'll hear about, and how to hold them wisely.

Prebiotic fiber — foods like cooked and cooled potato, green banana, oats, asparagus, and flaxseed — feeds your beneficial bacteria. But add it slowly. If you're already bloated, flooding the system with fiber can amplify the noise before it quiets. A little, then a little more.

Binders — such as activated charcoal or certain clays — can bind to compounds in the gut and are sometimes used to ease symptoms during a reset. These are more clinical tools, and they can also bind nutrients and medications. Please only use binders with the guidance of a qualified practitioner. This is not a self-experiment lesson.

A small practice for today

Before your next meal, pause for three slow breaths. Notice how your body feels before you eat — not to analyse, just to register a baseline.

Then, afterward, jot down one line: what you ate and how you felt two hours later. That's it. One line, one meal. You're not diagnosing yourself today. You're simply beginning to listen — turning years of override into the first quiet page of understanding.
