How many calories are in an aubergine?

A whole medium aubergine (around 230g) contains approximately 46 kcal. Per 100g, raw aubergine provides just 20 kcal — making it one of the lowest-calorie vegetables available. This is comparable to celery and cucumber. However, aubergine readily absorbs oil during cooking, so fried or roasted aubergine dishes can be significantly higher in calories.

Is eggplant good for blood sugar?

Eggplant (aubergine) is excellent for blood sugar management. It has a very low glycaemic index (estimated around 15), just 2.2g of carbohydrates per 100g, and 2.0g of fibre. An entire medium aubergine delivers only 5.1g of total carbs — negligible glucose impact. It is one of the safest vegetables for anyone managing diabetes or trying to avoid blood sugar spikes.

What is the difference between eggplant and aubergine?

Eggplant and aubergine are exactly the same vegetable (Solanum melongena). 'Aubergine' is the term used in the UK, France, and much of Europe, while 'eggplant' is the standard term in the US, Canada, and Australia. In Tesco and all UK supermarkets, you will always find it labelled as 'aubergine'. The nutritional profile is identical regardless of the name.

Nutritional Information for Eggplant (Aubergine)

Eggplant — known as aubergine in the UK — is one of the lowest-calorie vegetables available, at just 20 kcal per 100g. From a SpikeSaver perspective, it is essentially glucose-neutral: very low carbohydrates (2.2g per 100g), a very low GI, and zero processing in its whole form (NOVA 1). It is rich in fibre relative to its calorie content and contains virtually no fat, sugar, or salt. The main nutritional watch-point is prepared aubergine dishes (bakes, quiches, pickles) which can be significantly higher in calories and processing level.

Glucose impact

Glycemic Index

Very Low

Glucose risk

Aubergine has a very low glycaemic index (estimated below 20) and contains just 2.2g of carbohydrates per 100g, almost all of which is natural sugar. With 2.0g of fibre per 100g — nearly matching its total carb content — the glucose impact is negligible. An entire medium aubergine delivers only 5.1g of carbs. This makes aubergine one of the safest vegetables for blood sugar management.

Processing level

NOVA 1 (unprocessed)

A whole raw aubergine is an unprocessed single-ingredient product — just aubergine. It has no additives, preservatives, or flavourings. Tesco sells whole aubergines and baby aubergines with no ingredient list beyond the vegetable itself. However, prepared aubergine products such as Tesco Finest Roasted Aubergine Bake (NOVA 3) or Patak's Aubergine Pickles (NOVA 3) contain added oils, salt, sugar, and other ingredients that increase processing level.

What to watch for when shopping

Whole aubergines are always NOVA 1 and glucose-safe. The watch-point is prepared dishes: Tesco Finest Roasted Aubergine Bake jumps to 120 kcal/100g (6x the raw vegetable) due to added oils, and Patak's Aubergine Pickles hits 381 kcal/100g with 25g fat and 35g carbs per 100g. If buying whole, Tesco Aubergine Each at £0.95 is the best value. Note: in UK supermarkets this vegetable is always labelled 'aubergine' — the term 'eggplant' is used in American, Australian, and international contexts.
