Meals built soft and small-particle, which is the dietary lever a recipe can genuinely control and one current guidance supports. Portion size is yours to set: these are written at an ordinary serving and divide in two if you are eating smaller and more often. Diagnosing, curing or treating gastroparesis is not something food does. If eating is not going in, if you are dehydrated or losing weight without meaning to, that needs a clinician rather than a different recipe.
A registry of 305 people with gastroparesis found average intake at 58% of energy needs and 2% following the recommended diet. What that does to how the usual advice should be read.
Low fat and low fibre travel together in every gastroparesis handout, as though they had the same evidence standing behind them. They do not, and knowing which is which changes how tightly you should hold each one.
Liquid and blended meals get treated as the bottom of a ladder people feel ashamed to be standing on. The clinical logic runs the other way, because the realistic alternative to a blended meal is very often no meal at all.
One randomised trial sits underneath the advice, and what it randomised was not a menu. It was twenty weeks of teaching people to change what their food does after they have swallowed it.
The advice is one line long and its consequences fill a week. Splitting a day of nutrition across six sittings changes shopping, cooking, work and appetite, and the word doing the heavy lifting in it is nutritious.
Small meals, low fat, low fibre, small particles: the gastroparesis diet is four rules that get handed over as one. Only one has a randomised trial behind it, two are guideline implementation notes, and all four take food away from people who, in the largest registry study, were already eating far too little. Here is the whole picture on one page.
In diabetic gastroparesis the diet has two jobs that pull against each other: the stomach needs small, soft, low-fat meals, and the blood glucose needs carbohydrate that arrives when the insulin does. The only randomised trial of the small-particle diet was run in exactly this group. What it found, and how to eat so both jobs get done.
Every statement in these guides is recorded as a claim with its sources and the rule attached to it. Read the claim ledger for gastroparesis — 10 claims, each separately citable.
Rolled oats simmered well past the usual point and then blended with ripe banana, milk powder and a knob of butter into a pourable porridge with no grain left in it.
A whole tub of cottage cheese blitzed until the curd disappears and it turns to pourable cream, under pear poached soft and finished in a buttery honey syrup.
White rice simmered slowly in a little over three times its weight in liquid until the grains burst and dissolve, with beaten egg poured in at the end so it sets in fine threads.
Tinned peaches, Greek yoghurt and full-cream milk blended thin enough to drink, with milk powder stirred in first so the glass carries protein and energy rather than only sweetness.
A cornflour-set milk pudding, enriched with butter and milk powder and chilled until it just holds the shape of a spoon, with dried apricots stewed and blended smooth over the top.

Mushrooms cooked down hard with leek and thyme, thickened with potato and milk powder rather than cream, and served with a small round of soft cheese toast to dip and soften.
Cauliflower simmered with potato and leek until it crushes without resistance, blended smooth and enriched with butter, milk powder and Parmesan, with buttered toast fingers to go alongside.
Poached chicken chopped to a fine mince in a broth thickened with sweetcorn blended and pushed through a sieve, so the corn gives its flavour without its hulls.

Small pasta cooked well past al dente in a tomato sauce blended and sieved until it pours, with the rest of the ricotta tub whipped loose and spooned over.
Beef mince broken down to crumbs in a thickened gravy under a soft potato and cauliflower mash finished with cheddar, baked only until it is heated through rather than crusted.
A block of silken tofu slid into a mild tomato sauce thick with finely broken chicken mince, spooned over rice cooked past the point of separate grains.
Fish steamed until it falls into flakes, dressed with hot oil poured over shredded ginger and chives, with soft rice and zucchini cooked to giving point.
Capsicums roasted until the skins lift away, blended with milk into a sweet orange sauce, folded through turkey mince broken to crumbs and pasta cooked past al dente.
