Eating green isn't the whole diet

A green score means "gentle on the gut" — not "nutritionally complete". If you only ever ate the greenest foods, you'd be comfortable, but you'd miss some things that matter. Here's what to watch, and gentle ways to fill the gaps.

This is general information, not medical or dietary advice, and it can't tell you whether you're personally low in anything. Only a blood test can do that. Use it to have a better conversation with your GP or dietitian.

What a green-only diet looks like

Across our database, the green band is dominated by lean proteins, oils, gentle starches (white rice, peeled potato), some plant-milks and most herbs. But almost no fruit, vegetables, legumes, nuts or seeds make it into green — they tend to land in yellow or orange because of their fibre and fermentable-carb load.

Green covers these well

Protein, energy, and the nutrients that ride along with animal foods — iron, B12, calcium and vitamin D (from canned fish with bones), and omega-3s. You can eat very gently and still cover these.

Green struggles with these

Fibre and prebiotics, vitamin C, folate, and the broad plant variety behind antioxidants. These live mostly in fruit and veg, so you have to reach into yellow on purpose — in gentle, cooked, small-portion forms.

Gentle ways to fill the gaps

None of this means abandoning a gentle diet. It means topping it up thoughtfully. Pick the softest, best-tolerated source, keep portions modest, and reintroduce one new thing at a time.

Potassium

gentle sources exist

Fluid and electrolyte balance — especially if your output is high.

Try: Banana, peeled or mashed potato, cooked pumpkin, soft-cooked carrot.

Soluble fibre & prebiotics

gentle sources exist

Feeds the gut microbiome and gently firms output — the thing a low-residue diet loses most.

Try: Oats and oat bran, psyllium, a just-ripe banana, soft-cooked carrot. Add slowly with plenty of fluid.

Calcium & vitamin D

gentle sources exist

Bone health — a real risk if you limit dairy for lactose.

Try: Canned salmon or sardines with the bones, fortified plant milks, hard cheese; daylight for vitamin D.

Iron

best sources sit in yellow

Energy and red blood cells — iron-deficiency anaemia is common in IBD.

Try: Red meat, canned fish, eggs (gentle haem iron); cooked spinach paired with a vitamin-C food to absorb it.

B12

gentle sources exist

Nerves and blood cells — often poorly absorbed after ileal surgery, so worth testing.

Try: Eggs, fish, meat and dairy are all gentle sources. Ask your team to check your level.

Omega-3 fats

gentle sources exist

General and anti-inflammatory health.

Try: Oily fish — salmon, sardines, tuna — all score green.

Vitamin C

best sources sit in yellow

Immunity, wound healing, and helping you absorb plant iron.

Try: Strawberries, mandarin, papaya, cooked red capsicum — in small, tolerated portions (these sit in yellow).

Folate

best sources sit in yellow

Building blood cells and tissue repair.

Try: Soft-cooked spinach and gentle greens in modest amounts (yellow band).

Plant variety (the “rainbow”)

best sources sit in yellow

Polyphenols and antioxidants for long-term gut and general health.

Try: Rotate soft-cooked, peeled, colourful veg and fruit as you tolerate them — widen the range over time.

You don't have to fix every meal

If lunch and dinner are all beige, you don't need to force greens onto the same plate. Spread it across your day instead — a banana or oats at breakfast covers potassium and fibre, tinned salmon at lunch covers calcium and omega-3, a few strawberries as a snack add vitamin C. Small, gentle additions in the easiest part of your day add up.

The real fix: broaden over time

A very gentle diet is the right tool early after surgery or during a flare. But it's a starting point, not a destination. As your gut settles, most "non-green" foods can come back in gentler forms and smaller portions — cooked instead of raw, peeled instead of skin-on, a few berries instead of a bowl. Our Long-Term Health mode leans this way on purpose.

What about supplements?

We deliberately don't recommend specific supplements or doses — that's a medical decision, and getting it wrong has real downsides (iron can upset the gut, fat-soluble vitamins can build up to harmful levels, the wrong fibre can make things worse).

What we'd suggest instead:

•Ask your team to check your levels. B12, iron, vitamin D and folate are routinely monitored in pouch and IBD patients — so this is "please test me", not a big ask.
•See a dietitian for anything you do need to top up — they'll match it to your bloods and your gut.
•One that often does double duty: gel-forming fibre like psyllium can both firm output and add gentle fibre. Many people with a pouch or IBS use it — but introduce it slowly, with plenty of fluid, and check with your team first.
