Deep Dive

Aubergine brings satisfying bite and deep-purple goodness to any raw bowl. Beneath the glossy skin are protective plant pigments but keep the skin on for that nasunin boost and enjoy the gentle fibre and potassium lift that supports everyday heart, blood-sugar and digestive balance. This nutrient-rich fruit offers distinctive neuroprotective, metabolic, and cardiovascular benefits through its unique anthocyanin and polyphenol profile, making aubergine an exceptional component of a health-promoting diet.

Why You'll Love It

• The polyphenols in aubergine slow the absorption of glucose, supporting balanced blood sugar levels after meals.
• Light yet satisfying: Very low in calories and fat, with gentle fibre and high water content - making aubergine great for fullness and texture without heaviness.
• Antiangiogenic activity: Nasunin inhibits micro-vessel outgrowth, suggesting potential to prevent tumour angiogenesis and disease progression.
• Antioxidant-rich skin: The deep purple peel is packed with nasunin, an anthocyanin that helps protect cell membranes - especially in the brain - from oxidative stress. Keeping the skin on means keeping the benefits.
• Skin health: Chlorogenic acid and nasunin are also protecting skin cells from UV-induced oxidative damage and may reduce photoaging.
• Chlorogenic acid for cell defence: This phenolic acid in the flesh has been linked with reduced LDL oxidation and gentle anti-inflammatory activity, adding cardiovascular support.

Health Benefits

Neuroprotection and cognitive health
Eggplant’s purple pigment, nasunin, can cross the blood-brain barrier and helps protect brain cell membranes from oxidation. Nasunin also improves cerebral blood flow and safeguards nerve cell function, supporting memory, learning, and potentially preventing neurodegenerative diseases such as Alzheimer’s and Parkinson’s. Keep the skin on to capture most of this pigment.

Cardiovascular support (fibre + potassium + polyphenols)
Aubergine contributes potassium, which supports healthy blood pressure, plus fibre that helps a heart-smart pattern by improving overall lipid quality and fullness.

Cholesterol regulator
Chlorogenic acid and nasunin in aubergines contribute to lowering LDL cholesterol through inhibition of cholesterol synthesis and enhanced bile acid excretion. Research indicates that eggplant extract reduces total cholesterol by 10–17%, and LDL by 8–15% in animals. Their antioxidant compounds also prevent LDL oxidation, a key step in atherosclerosis development.

Blood sugar regulation and diabetes prevention
High fibre (3.0g per 100g) and the presence of chlorogenic acid help slow carbohydrate absorption, improving glucose control. Clinical studies show that regular aubergine consumption reduces fasting blood glucose by up to 12% and improves insulin sensitivity through modulation of glucose transporters in the intestine.

Weight management and satiety
With only 25 calories per 100g and 92% water, aubergines are extremely low in energy density while providing 3.0g of fibre to promote fullness and reduce overall calorie intake. The fibre bulks in the gut, enhancing satiety hormones without spiking blood sugar, aiding weight loss and maintenance.

Gut health and prebiotic effects
The combination of insoluble fibre (cell wall polysaccharides) and polyphenols in aubergines supports gut microbiome diversity. Studies report increased abundance of Bifidobacteria and butyrate-producing bacteria after aubergine intake, leading to improved colon health and reduced inflammation.

Anti-inflammatory and antioxidant support
Aubergine flesh is naturally high in chlorogenic acid, while the peel concentrates anthocyanins - a duo repeatedly identified as the main phenolics in eggplant. Together they contribute to the vegetable’s overall antioxidant capacity and reduction of pro-inflammatory cytokines.

Bone health
Manganese (0.24mg per 100g) and chlorogenic acid support bone metabolism. Animal studies indicate increased bone mineral density and reduced fracture risk with regular aubergine extract supplementation.

Everyday mineral lift
Small but useful amounts of magnesium and potassium support normal muscle and nerve function alongside heart rhythm - nice extras from a low-calorie addition.

Why It Works – Scientific Insight

• Nasunin (anthocyanin) → membrane protection: Demonstrates superoxide/hydroxyl radical scavenging and iron-chelating activity, mechanisms relevant to oxidative stress in neural tissues.

• Chlorogenic acid → dominant polyphenol: Identified as the main phenolic in eggplant flesh across cultivars; contributes antioxidant activity and is implicated in cardiometabolic pathways in broader literature.
• Fibre & potassium → cardiometabolic nudges: Dietary fibre helps curb hunger and supports healthy blood lipids; potassium intake from fruit and veg patterns helps maintain normal blood pressure.
