What is this ingredient?

Eggplant (Solanum melongena) belongs to the nightshade family, the same family as tomato, pepper, and potato. The vegetable originally comes from India and has been cultivated for over 4000 years.

What makes eggplant special is its deep purple skin. This color comes from nasunin, an anthocyanin that is among the most widely recognized antioxidants. Nasunin is unique because it can 'chelate' iron - bind and remove it - which acts as an antioxidant, especially in the brain.

Expert Tip: Eat the skin! That's where 90% of the nasunin is. Cut the eggplant and sprinkle with salt to remove bitter juices before cooking.

How does it taste?

Mild and slightly bitter raw, creamy and meaty with umami when grilled or roasted.

Pairs well with:

Pairs well with tomatogarlictahinimiso and feta.

Did you know...?
  • The name 'eggplant' comes from early European varieties that were white and egg-shaped.
  • The aubergine is botanically a berry, not a vegetable.

What's being researched?
Cardiovascular

Nasunin and cholesterol research

Nasunin, an anthocyanin in eggplant skin, is being researched for potential effects on cholesterol levels. Animal studies show promising results, but human studies are limited.

Supported by: [1] Noda (2000) , [2] Noda Y (1998)

Other

Chlorogenic acid and oxidative stress

Chlorogenic acid in eggplant is being studied for protective effects against oxidative cell damage. Laboratory studies are promising, but more clinical research is needed.

Good Combinations (Synergy)

Combine eggplant smartly to enhance the effect:

Complementary
Eggplant Eggplant Chickpeas Chickpeas

Complete vegetarian meal: protein + fiber + nasunin

Technical: Eggplant contains only 1g protein per 100g but is rich in nasunin (antioxidant) and fiber (3g/100g). Chickpeas provide 19g protein per 100g with all essential amino acids. Combined fiber (10g+) feeds Bifidobacterium in the gut.

What does this mean for you? Eggplant curry with chickpeas perfectly complements the missing protein and provides a substantial fiber boost. Chickpeas bring the protein, eggplant the fiber and nasunin. An ideal complete vegetarian meal.

Synergy
Eggplant Eggplant Garlic Garlic

Chlorogenic acid + allicin: complementary NF-κB modulation

Technical: Eggplant contains chlorogenic acid (NF-κB modulation) and nasunin (iron chelator influencing lipid peroxidation). Garlic's allicin (formed when cut) has bioactive action via thiol enzyme inhibition. Together they modulate NF-κB signaling through complementary pathways.

What does this mean for you? Baba ganoush or imam bayıldı — classic combinations that have existed for centuries. Cut garlic 10 minutes before heating for maximum allicin formation.

Absorption 3×
Eggplant Eggplant Olive Oil Olive Oil

Fat makes nasunin (purple antioxidant) absorbable

Technical: Nasunin in the purple eggplant skin is a fat-soluble anthocyanin that crosses the blood-brain barrier. Olive oil's unsaturated fats (73% oleic acid) form micelles that increase nasunin absorption up to 3x.

What does this mean for you? Eggplant absorbs oil like a sponge — that's actually an advantage! The oil makes nasunin absorbable. Fry in olive oil for maximum effect.

Synergy
Eggplant Eggplant Tomato Tomato

Nasunin + lycopene: complementary carotenoid-polyphenol pathways

Technical: Nasunin (eggplant) and lycopene (tomato) work through different mechanisms. Nasunin chelates iron, influencing lipid peroxidation, while lycopene quenches singlet oxygen. Studies show combined polyphenols and carotenoids work synergistically — the combination works through complementary mechanisms. With olive oil, both are optimally absorbed.

What does this mean for you? Parmigiana, ratatouille, zaalouk — Mediterranean and North African dishes always combine eggplant, tomato and olive oil. Culinary tradition backed by science.

Storage

Location:Refrigerator

Shelf life:5-7 dagen

Store in the crisper drawer, not in plastic. Eggplant is sensitive to cold - don't store below 10°C. Cut just before use.

Preparation

Fry in olive oil — this helps fat-soluble nutrients like nasunin come into their own. Sprinkle with salt and let rest 30 min to remove bitter juices. Grill or bake until soft.

Time15-20 minuten Temp180-200°C (oven)

Conversions

82g= 1 cup 400g= 1 piece

Substitutes

courgette 1:1 Similar texture when cooked

Smart preparation

1Sprinkle slices with salt and drain for 30 minutes before frying.

Why?

This draws out moisture and bitterness and reduces oil absorption.

2Pierce a whole eggplant before grilling to prevent steam explosions.

3Fry eggplant on high heat; low heat causes it to absorb too much oil.

Caution / Warnings

Eggplant is very safe, but there are scientific considerations:

Nightshade sensitivity Mild

People with a known sensitivity to nightshade plants (solanaceae) may experience discomfort when consuming eggplant.

Kidney stones (oxalates) Moderate

Eggplant contains oxalates, which in susceptible individuals may contribute to the formation of kidney stones. Consult a doctor if you have a history of kidney stones.

Traditional use

Ayurveda

Ayurvedic use in India

In Ayurveda, aubergine was valued for helping to balance Kapha. It has been cultivated in India for over 1500 years.

Traditional Chinese Medicine

Traditional Chinese cuisine

In traditional Chinese medicine, aubergine was considered a cooling food that dispels heat from the body and promotes blood circulation.

Summary

Eggplant is an underrated vegetable with a secret weapon: nasunin. This powerful antioxidant in the purple skin protects your brain cells and binds excess iron.

To benefit maximally: always eat the skin, fry in olive oil (the antioxidants are fat-soluble), and combine with garlic and tomato for a classic Moroccan zaalouk. Eggplant is also perfect for weight loss: extremely few calories for lots of volume.
