Smart Choices — If You're Going to Do It, Do It Informed

The Harm Reduction Principle

Here's something I believe that puts me at odds with a fair number of practitioners in this space: not all "bad" things are bad, and the dose makes the poison.

I've watched too many clients — motivated, intelligent people — burn out on perfection. They eliminate gluten, dairy, sugar, alcohol, caffeine, seed oils, lectins, oxalates, and histamine all at once, then wonder why they're miserable, socially isolated, and not actually feeling any better. The stress of dietary perfection can do as much cortisol damage as the foods they're avoiding.

That doesn't mean everything is fine. It means the clinical approach should be targeted, evidence-informed, and proportional — not ideological. If your anti-tissue transglutaminase antibodies are elevated and there's blood in your stool and you eat bread daily, we need to talk about gluten. That's testing-driven. If your blood markers are clean and your gut is healthy, the occasional sourdough isn't going to kill you.

The same principle applies to coffee, wine, air quality, and everything else in this article. I'm not telling you what to do. I'm showing you what the data says and pointing you toward smarter options — so that when you make a choice, you make it informed.

The Air You Breathe

Most people obsess over what they eat and drink but never think about what they breathe — and yet you take roughly 20,000 breaths a day. If your indoor air contains elevated volatile organic compounds, particulate matter, or excessive CO₂ (common in poorly ventilated offices and bedrooms), that's an invisible detoxification burden your liver processes every hour of every day.

I started monitoring my own indoor air quality a few years ago and the data was genuinely surprising. CO₂ levels in a closed bedroom overnight regularly exceeded levels associated with cognitive impairment. VOC spikes after cleaning products were measurable for hours. These aren't theoretical concerns — they're quantifiable exposures that contribute to the detox burden I measure on functional tests.

Your Gut, in Real Time

The GI-MAP tells me what's living in your gut. But it doesn't tell you which specific foods ferment excessively for your individual microbiome on a given day. That's where breath testing comes in — and until recently, it required a clinical visit and a lactulose challenge test.

FoodMarble changed that. It's a personal breath hydrogen and methane monitor that lets clients track their fermentation responses to specific foods at home. If your GI-MAP shows dysbiosis and you're symptomatic, this device identifies which fermentable carbohydrates are driving the bloating, gas, and discomfort. It bridges the gap between stool test findings and daily food decisions.

Coffee — The Mycotoxin Question

I'm not anti-coffee. For most people, moderate coffee consumption is a net positive — antioxidant-rich, neuroprotective, and one of the genuine pleasures of daily life. The issue isn't coffee itself. It's what's in the coffee.

Conventional coffee is one of the most heavily pesticide-sprayed crops in the world, and it's susceptible to mycotoxin contamination — specifically ochratoxin A and aflatoxin. If your OAT test shows elevated mycotoxin markers, one of the first questions I ask is about your coffee source. For clients drinking two or three cups daily, switching to a tested, mycotoxin-free source is one of the simplest environmental load reductions available.

Wine — If You're Going to Drink

This is where some practitioners lose me. The absolute prohibition of alcohol in every clinical context ignores the reality that most adults — including many very healthy adults — drink moderately, and the stress of social abstinence can outweigh the biochemical cost of a sensible glass of wine.

What I will say is that not all wine is equal. Conventional wine carries a sulphite load that burdens liver detoxification pathways, a histamine load that triggers reactive clients, and pesticide residues that biodynamic and organic options avoid. The difference is measurable — clients with histamine intolerance or elevated liver markers notice it immediately.

If you're going to have a glass, make it one that minimises the biochemical cost. Low-sulphite, organic, or biodynamic wines are a reasonable harm-reduction strategy. I'm currently researching specific UK sources and will add recommendations here when I've found ones I'm confident in.

The Principle

Every recommendation on this page follows the same logic that drives everything else I do: test, don't guess. If your OAT shows mycotoxins, switch your coffee. If your GI-MAP shows dysbiosis, track your fermentation. If your detox markers are elevated, check your air. If your liver is clean and your gut is solid, enjoy your evening without guilt.

The goal isn't perfection. The goal is informed, proportional, testing-driven decision-making applied to the choices you were going to make anyway.

A little of what you like does you good — as long as you know what "good" actually means for your specific biology.
