The Thrive Nutrition App lists UK potato varieties and several potato states per 100 g, but they do not each have their own lab row.
Agria potato, Maris Piper potato, King Edward potato, Desiree potato and Baking potato all use USDA FDC SR Legacy 170026 (Potatoes, flesh and skin, raw) — the variety cards as a Closest match. Baking potato is Measured: it is that raw flesh-and-skin row itself. It stays on this row; this page does not treat it as a russet-specific analysis or swap it for another record.
Two other raw rows are distinct: Red potato uses USDA FDC SR Legacy 170029 (Potatoes, red, flesh and skin, raw), and New potatoes uses CoFID 2021 13-618 (Potatoes, new and salad, flesh only, raw), which Charlotte potato also uses as a Closest match.
The generic Potato card is not raw: it is CoFID 2021 13-490, Potatoes, old, boiled in unsalted water, flesh only (peeled, boiled in unsalted water). That fact belongs in the lead because the slug simply says “potato.”
The table shows each distinct source row once. A blank cell means Missing. Raw flesh-and-skin, raw flesh-only, and boiled flesh-only are different states and parts, from different datasets, and should not be read as a like-for-like variety test.
The cards already name the plant as Solanum tuberosum.
Which cards share a row
- USDA FDC SR Legacy 170026 — raw, flesh and skin. Representative: Baking potato (Measured). Closest match: Agria potato, Maris Piper potato, King Edward potato, Desiree potato.
- USDA FDC SR Legacy 170029 — red, raw, flesh and skin. Red potato (Measured). Not a named UK cultivar card.
- CoFID 2021 13-618 — new and salad, raw, flesh only. New potatoes (Measured); Charlotte potato (Closest match).
- CoFID 2021 13-490 — old, boiled in unsalted water, flesh only. Potato (Measured).
Floury versus waxy is a taste and kitchen-use note (Agria and Maris Piper are often used for roasting, frying or mash; Charlotte and red potatoes hold a salad). It is not extra nutrient data. Varieties on the shared raw row do not differ in the Thrive Nutrition App’s recorded figures.
USDA and CoFID are different datasets. Small differences between rows are not described here as a cooking effect or a variety effect, because the rows are not the same state, part and source.

Named varieties on the Thrive Nutrition App
- Agria — floury; a common frying and roasting potato in Spain, also sold in the UK. Recorded data: USDA FDC SR Legacy 170026 as a Closest match.
- Maris Piper — floury UK roast, mash and chip potato. Same shared raw row.
- King Edward — same shared raw row.
- Désirée — the card slug is potato-desiree; same shared raw row.
- Charlotte — waxy salad potato. Recorded data: CoFID 2021 13-618 as a Closest match.

What these cards do not cover
The named variety cards already exist. What is missing is variety-specific composition data, and some cooked states. These are candidates for a later batch only; they are not rows on this page.
- A USDA or CoFID row actually analysed as Agria, Maris Piper, King Edward or Désirée.
- A CoFID raw old-potato row (distinct from both the boiled card and the USDA raw flesh-and-skin row).
- A cooked baked or jacket potato. Baking potato is raw flesh and skin, not a baked row.
- Roasted potato.
- Mashed potato. A CoFID mash-with-butter record would not be a generic mash card.
This page does not list russet as a missing card. The baking-potato card already covers that slot on USDA FDC SR Legacy 170026.
How to read the numbers
- Values are per 100 g in the state and part named on each card.
- USDA 170026 and 170029 are flesh and skin, raw. CoFID 13-618 is flesh only, raw. CoFID 13-490 is flesh only, boiled in unsalted water.
- A dash is Missing. Blank is not zero.
- Measured means the representative card is the source row itself. Closest match means a variety card shares that row.
- % NRV (UK) is shown only for potassium and vitamin C. Energy and protein have reference intakes; fibre has no NRV.

FAQ
What is the nutrition of Agria / Maris Piper potatoes?
The Thrive Nutrition App uses USDA FDC SR Legacy 170026 (Potatoes, flesh and skin, raw) as a Closest match on Agria potato and Maris Piper potato. The figures match the other cards on that row, including Baking potato. Taste and use are not in the table.
How do raw and boiled potatoes compare per 100 g on the Thrive Nutrition App?
Compare USDA FDC SR Legacy 170026 (raw, flesh and skin) with CoFID 2021 13-490 (old, boiled, flesh only). Different state, different part, different dataset — not a simple before-and-after of one potato.
Are new potatoes a different variety in the data?
New potatoes uses CoFID 2021 13-618, Potatoes, new and salad, flesh only, raw. Charlotte potato shares that row as a Closest match. It is a different record from USDA FDC SR Legacy 170026, not a second analysis of Maris Piper.
Is /foods/potato/ a raw potato?
No. It is Potatoes, old, boiled in unsalted water, flesh only (CoFID 2021 13-490).
Do you have a baked jacket-potato row?
Baking potato is raw, on USDA FDC SR Legacy 170026. A cooked baked row is a gap.
Where do the nutrient numbers come from?
Each card’s USDA FoodData Central or UK CoFID 2021 record per 100 g, taken from the built card. See About our data.
