Eggplant for Dinner - Garnering Interest in Fruit Phenolic Constituents

Tonight I added an eggplant to our chili just to see if my husband would say anything. Eggplant holds a position of some importance in the menu choices at our house as it is a staple of the Mediterranean diet. When we go out (or order out) for Persian food we usually include an order for some eggplant stew (with or without the veal in it). During Lent this is my husband's favorite meal- vegetarian eggplant stew from our favorite Persian restaurant.
I looked up the nutrition information about eggplant on the Internet and found this:

Eggplant is:

• Low in Saturated Fat, Sodium, and Cholesterol
• High in Dietary Fiber, Folate, Potassium, Manganese, Vitamin C, Vitamin K, Thiamin, Niacin, Vitamin B6, Pantothenic Acid, Magnesium, Phosphorus and Copper

The nutritional value and health benefits of eggplant makes it ideal for:

• Maintaining optimum health
• Weight loss

Don't include too many eggplants in your diet if you're interested in:

• Weight gain

 Since I am currently still losing pregnancy pounds this piqued my attention. Is there any chemical in particular that makes eggplant good for weight loss? I'm really interested.
Here is a quotation from the chemical literature about eggplant:
"Eggplant (Solanum melongena L.), fruit commonly known as
aubergine, melanzana, garden egg, brinjal, or patlican is ranked
amongst the top ten vegetables in terms of oxygen radical absorbance
capacity due to the fruit phenolic constituents (Cao, Sofic,
& Prior, 1996). The colour, size, and shape of the eggplant fruit vary
significantly with the type of the eggplant cultivar, and its fruit is
commonly cooked as a vegetable in many parts of the world. The
cultivated eggplant has significant economic importance in many
tropical and subtropical parts of the world. In the United States,
the consumption of eggplant is increasing due to growth in ethnic
diversity and greater awareness of the health beneficial effects
associated with increased consumption of fruits and vegetables."
