Cole names four food categories most likely to disrupt the gut-immune axis in a modern Western diet: gluten-containing grains, industrial seed oils, added sugar, and conventional dairy. The framework's mechanism is an evolutionary mismatch argument — our genetics have barely shifted in 10,000 years while these foods have been refined, sprayed, and industrialised beyond what our microbiome co-evolved with. Rather than banning them, the method is informed consent: for each of the four, learn what it does, then pick the ancestral or better-prepared version (sourdough over bleached wheat, olive oil over corn oil, whole fruit over agave, fermented A2 dairy over regular milk) or reduce the dose. Bio-individuality is explicitly built in — some people tolerate some of these fine, so the output is a personal reduction plan, not a universal prohibition.

Core principles
- 01Informed consent beats moral indictment — know both sides of a food, then choose
- 02Bio-individuality is real: some people tolerate these foods with no symptoms
- 03Most trouble is what modernity did to the food, not the food category itself
- 04Ancestral preparation (soaking, sprouting, fermenting) reduces the mismatch
- 05Swap ratios rather than banning: more omega-3, less omega-6
How to run it
- 1
Reframe from moral to informational
Drop the good-food/bad-food framing. The goal is informed consent: you know what each food does and choose deliberately.
Pro tip Say 'this doesn't love me back' rather than 'I'm being bad' — it makes the choice self-respect, not restriction.
Watch out Moralising food is what feeds the shame spiral that raises inflammation in the first place.
- 2
Address gluten-containing grains
Target mainly modern bleached, refined wheat. Where bread stays, use sourdough — fermentation breaks down gluten the way ancestral soaking and sprouting did.
Pro tip Ask whether the problem is the grain or what has been sprayed on the grain.
- 3
Rebalance the fats
Cut industrial seed oils — vegetable, corn, soybean, canola — which push omega-6 far out of historical ratio. Raise omega-3 via wild-caught fatty fish, grass-fed beef, olives, extra virgin olive oil.
Pro tip Extra virgin olive oil pays twice: fat content plus polyphenols that act as prebiotics for the microbiome.
Watch out Seed oils are not inherently toxic; the issue is the ratio in the modern Western diet.
- 4
Hunt added sugar behind nice names
Read the grams of added sugar on labels. Treat agave nectar and similar as the green-washing of sugar — highly refined and high in fructose.
Pro tip A healthy-sounding label is not a licence for copious amounts.
- 5
Upgrade dairy rather than dropping it
Conventional milk is A1 beta-casein; our ancestors drank A2 for thousands of years. Move to grass-fed organic A2, and prefer fermented forms — kefir, yoghurt, sheep and goat cheeses.
Pro tip Fermentation makes A2 dairy better still.
Watch out The food sensitivity may be to the casein subtype, not to dairy as a category.
- 6
Build the plate back with density
Fill the space with bioavailable nutrient density: 90-100g/day of clean protein, healthy fats, and fibre-rich whole-food carbs like sweet potatoes, parsnips, squashes, and fruit.
Pro tip If your gut is stressed, cook the fibre down — soups, stews, broths, and stewed fruit are easier to digest.
Watch out Do not fear carbs; fibre-rich plants feed microbiome diversity.
- 7
Personalise by reintroduction
Bring items back one at a time and observe. Bio-individuality means your tolerance list will not match anyone else's.
Pro tip Pair the subjective read with labs so you correlate feeling with data.
In the wild
Cole describes patients who are, in his words, the quintessential biohacker — eating the best food under the sun, taking the right supplements, listening to all the podcasts. Their food column is immaculate. Yet their inflammation markers stay elevated, because the core four audit only covers the physical plate; they are still serving themselves a big slice of stress and shame each day. The framework's honest boundary shows here: cleaning up the four foods moves the needle, but it is one input into a bigger system, and Cole pairs it with the mental-emotional work rather than selling it as the whole answer.
→ Food changes alone plateau; the core four is necessary but not sufficient without the shame-flammation work.
For a stressed-out, disregulated, inflamed gut, Cole points at what traditional medicine systems — Ayurvedic, traditional Chinese, folk chicken soup — already knew. The therapeutic part is not the noodles: it is the broth, the vegetables cooked down and easy to digest, the protein cooked down and easy to digest. Someone whose gut cannot handle a raw salad runs a souping and brothing protocol instead, getting fibre-rich vegetables and clean protein in a pre-digested form while the core four come out.
→ Fibre and protein intake stays high without the digestive load that raw whole foods place on an inflamed gut.
Common mistakes
Treating the four as a permanent blacklist
Cole is explicit that this is not a moral indictment and that bio-individuality means some people tolerate some of these with no problem. Blanket elimination misses the point and usually breeds shame.
Swapping sugar for a nicer-sounding sugar
Agave nectar and similar euphemisms are highly refined and high in fructose. A wholesome label does not change the grams of added sugar.
Fixing the plate while ignoring the stress load
People with high shame and stress scores show high inflammation regardless of diet quality. Perfect food with unaddressed chronic stress leaves the inflammation in place.
Is it for you?
Best for
Busy high performers who feel fine-ish but suspect food is capping their energy, mood, and focus.
Not ideal for
Anyone with a history of disordered eating who would turn a four-item list into another rigid rulebook.
