What the tomatoes numbers show

498 of the 558 tomatoes products carry 20 calories or more per 100g, which is the floor below which protein per 100 calories stops being a real number. Across those the median is 4.3g of protein per 100 calories. Not one of them clears 10g of protein per 100 calories, which is the line Keith uses for a food that pays for its calories.

Calories run from 20 to 580 per 100g inside this one group, a 29-fold spread, so “tomatoes” on its own tells you almost nothing about what a portion costs you.

Name brands do lead this one: 4.4g of protein per 100 calories at the median across 338 products, against 4g for the 160 own-label ones.

The chains are not equal on this: Lidl runs a median of 3.9g of protein per 100 calories across its 56 own-label tomatoes products, Dunnes Stores 3.5g across 27.

What to actually pick

Nothing here is a protein food, so treat it as calories. At a median of 4.3g of protein per 100 calories this group is a taste and energy decision, not a macro one.

13 of the 498 carry 400 calories or more per 100g — the ones worth weighing rather than eyeballing.

Where this fits

That chain-by-chain gap is why the biggest ranges get their own page: Lidl Tomatoes covers 56 products, and everything else Lidl sells sits alongside it.

Front-of-pack claims on this stuff rarely match the back, so scan it with the label checker.

For one specific product rather than the whole group, the 20,000-product database is searchable on Calories in Ireland, and the same figures are built into the calorie app.

Real barcode-matched products with a confirmed photo — the same rule as Calories in Ireland: a photo only shows where we have a confirmed Open Food Facts match, never a guessed stock image.

FAQ

How many tomatoes products are in this database?

We track 558 tomatoes products across Irish supermarkets and brands. 498 of them carry 20 calories or more per 100g, which is the point below which protein per 100 calories stops being a real number, so those are the ones ranked and averaged here.

What's the most protein-dense tomatoes product?

The table is sorted highest protein per 100 calories first, so the answer is the top row. The more useful number is that the median for the whole group is 4.3g per 100 calories and 0 products clear 10g — that tells you whether tomatoes is worth buying for protein at all, which protein per 100g does not.
