Eggplant (aubergine)
In plain English
Eggplant is a nightshade, like potatoes and tomatoes, and it makes its own : about 0.96–1.77 mg per 100 g in commercially unripe to ripe fruit, rising to about 15 mg in overripe fruit (converted from dry weight). EFSA could not characterize the risk, because there is too little data. Eggplant also contains a trace of nicotine: even at the highest published figure, you would need 70–210 kg a day to match one nicotine patch.

Ripe fruit is the one part of a plant that 'wants' to be eaten, so its seeds get spread, and it drops its defenses as it ripens. Green tomatoes carry 0.9–55 mg of tomatine per 100 g; red ones 0.03–0.08 mg (Friedman & Levin 1995). Seeds, roots, tubers and leaves stay defended.

Daily amounts per 100 g raw
The same 100 g against five sets of daily amounts for adults aged 31–50: US/Canada (National Academies), UK (PHE 2016), EU (EFSA), Australia/NZ (NHMRC) and WHO/FAO. Your choice is highlighted. Each line names its type (RDA, RNI, PRI, RDI, AI, and so on) and links to its source. Label amounts, with no absorption factors. Where a body sets no value, it says so; no other body's figure is used instead.

What comes with it: what the carbohydrate becomes
Per 100 g as eaten, from UK CoFID 2021 (McCance and Widdowson). CoFID gives starch and sugars as monosaccharide equivalents, so half of sucrose counts as glucose and half as fructose. This is a different measure from USDA's “carbohydrate, by difference” in the table above, and the two are never mixed.
eggplant
Most of the carbohydrate in raw eggplant is sugar. 100 g ends up as about 1.35 g of glucose and about 0.85 g of fructose.

- Threshold
- No established threshold [source]EFSA 2020: 'For tomato and aubergine GAs, the risk to human health could not be characterised due to the lack of occurrence data and the limited toxicity data.'
- Effect
- Risk not characterized by EFSA. Levels rise sharply in overripe fruit. Regulatory assessment
Nicotine (trace)
- As the source gives it
- 0.0002–0.01 mg/100 g, fresh [source]
- Dose
- raw: 0.0002–0.01 mg in 100 gboiled: 0.0002–0.01 mg in 100 g (raw value; the source gives no cooking figure)
- Threshold
- No established threshold
- Effect
- Trace. Even at the higher figure, you'd need 70–210 kg of aubergine a day to match one nicotine patch. Human observational study
