Healthier food swaps

Pick a food and see the alternatives in the same category that are lower in calories, higher in protein or higher in fibre — 150 foods covered, every difference computed from the same database.

How a swap is worked out

A swap here is a comparison, not a recommendation. For any food, the page takes every other food in the same category of the database and sorts it three ways: lower energy per 100 g, higher protein per 100 g, and higher fibre per 100 g. Each table shows the alternative’s own figure and the difference against the food you started with, so you can see the size of the change rather than a verdict.

Staying inside one category is what makes the comparison mean anything. Swapping a cheese for a cucumber saves a lot of calories and does not replace the cheese; swapping a cheese for a lighter cheese might. The category boundary is the database’s own, and every alternative links to its full page so you can check the numbers rather than take them from a table.

The candidate list is filtered mechanically to plainly-named foods: no comma in the name, at most three words in the identifier, and no cooking, canning, drying or reconstitution qualifier. That removes the long laboratory variants of the same food and leaves the entries you would recognise in a shop. It also means a swap table is a subset of the category, not all of it.

The weekly arithmetic is deliberately plain multiplication. A saving per portion, times three times a week, times fifty-two weeks. It is what the numbers say, and it assumes you change nothing else — which is exactly the assumption that usually fails in practice.

These are per-100 g database averages for whole foods, not a diet plan. Energy is only one property of a food: protein, fibre, salt, cost, satiety and whether you will actually eat it all matter, and none of them is settled by a calorie column. Nothing here is medical or dietary advice and nothing here is a diagnosis. If you are managing a condition, an allergy or a prescribed diet, speak to a clinician or a registered dietitian.
