Eggplant is very low in calories and fats but rich in soluble fiber content. 100 g provides just 24 calories but contributes about 9% of RDA (recommended daily allowance) of fiber.

Research studies conducted at the Institute of Biology of São Paulo State University; Brazil suggested that eggplant is effective to control high blood cholesterol.

The peel or skin (deep blue/purple varieties) of aubergine has significant amounts of phenolic flavonoid phyto-chemicals called anthocyanins.

Scientific studies have shown that these anti-oxidants have potential health effects against cancer, aging, inflammation, and neurological diseases.

Total antioxidant strength measured in terms of oxygen radical absorbance capacity (ORAC) of aubergines is 993 µmol TE/100 g. At value 15; they are one of the low glycemic index (GI) vegetables.

It contains good amounts of many essential B-complex groups of vitamins such as pantothenic acid (vitamin B5), pyridoxine (vitamin B6) and thiamin (vitamin B1), niacin (B3).

These vitamins are essential in the sense that body requires them from external sources to replenish and required for fat, protein and carbohydrate metabolism.

Further, this vegetable is an also good source of minerals like manganese, copper, iron and potassium. Manganese is used as a co-factor for the antioxidant enzyme, superoxide dismutase.

Potassium is an important intracellular electrolyte that helps counter pressing (hypertension) effects of sodium.
