Not long ago Sasha Ottey of PCOS Challenge e-mailed me to see if I knew anything about"eggplant water". Seems it had been written up in the Los Angeles Times as a weight loss aid. It sounded strange, and she was looking to see if there was any scientific backing.
I was a little skeptical, but I did go to the National Library of Medicine database to see if anything existed. There was nothing about eggplant water specifically, but I did find a research abstract about the potential benefits of an eggplant-based diet. It appears that the antioxidants in eggplant are especially good for combating the types of degenerative processes common to insulin resistance.
Here it is, along with the reference. And below that, is a recipe for ratatouille, my favorite eggplant recipe. Enjoy!
National Diabetes Education Program of NIH, Mayo Clinic and American Diabetes Association recommend eggplant-based diet as a choice for management of type 2 diabetes. The rationale for this suggestion is the high fiber and low soluble carbohydrate content of eggplant. We propose that a more physiologically relevant explanation lies in the phenolic-linked antioxidant activity and alpha-glucosidase inhibitory potential of eggplant which could reduce hyperglycemia-induced pathogenesis. Results from this study indicate that phenolic-enriched extracts of eggplant with moderate free radical scavenging-linked antioxidant activity had high alpha-glucosidase inhibitory activity and in specific cases moderate to high angiotensin I-converting enzyme (ACE) inhibitory activity. Inhibition of these enzymes provide a strong biochemical basis for management of type 2 diabetes by controlling glucose absorption and reducing associated hypertension, respectively. This phenolic antioxidant-enriched dietary strategy also has the potential to reduce hyperglycemia-induced pathogenesis linked to cellular oxidation stress. These results provide strong rationale for further animal and clinical studies.

Ratatouille
2 1/2 lb tomatoes (4 large)
8 large garlic cloves, thinly sliced
1 cup chopped fresh flat-leaf parsley
20 fresh basil leaves, torn in half
1 cup plus 2 tablespoons extra-virgin olive oil
2 lb eggplant, cut into 1-inch cubes
2 1/4 teaspoons salt
2 large onions (1 1/2 lb total), quartered lengthwise and thinly sliced crosswise
3 assorted bell peppers (green, red, and/or yellow; 1 1/2 lb total), cut into 1-inch pieces
4 medium zucchini (2 lb), quartered lengthwise and cut crosswise into 3/4-inch-thick pieces
1/2 teaspoon black pepper
Garnish: Parmigiano-Reggiano shavings and fresh basil
Cut an X in bottom of each tomato with a sharp paring knife and blanch together in a 4-quart pot of boiling water 1 minute. Transfer tomatoes with a slotted spoon to a cutting board and, when cool enough to handle, peel off skin, beginning from scored end, with paring knife.
Coarsely chop tomatoes and transfer to a 5-quart heavy pot with garlic, parsley, basil, and 1/3 cup oil. Simmer, partially covered, stirring occasionally, until tomatoes break down and sauce is slightly thickened, about 30 minutes.
While sauce is simmering, toss eggplant with 1/2 teaspoon salt in a large colander and let stand in sink 30 minutes.
Meanwhile, cook onions in 3 tablespoons oil with 1/4 teaspoon salt in a 12-inch heavy skillet over moderate heat, stirring occasionally, until softened, 10 to 12 minutes. Transfer onions with a slotted spoon to a large bowl, then add 3 tablespoons oil to skillet and cook bell peppers with 1/4 teaspoon salt over moderate heat, stirring occasionally, until softened, about 10 minutes. Transfer peppers with slotted spoon to bowl with onions. Add 3 tablespoons oil to skillet and cook zucchini with 1/4 teaspoon salt over moderate heat, stirring occasionally, until just tender, 6 to 8 minutes. Transfer zucchini with slotted spoon to bowl with other vegetables.
While zucchini are cooking, pat eggplant dry with paper towels. Add remaining oil (about 1/4 cup) to skillet and cook eggplant over moderate heat, stirring occasionally, until softened, 10 to12 minutes.
Add vegetables, remaining teaspoon salt, and black pepper to tomato sauce and simmer, covered, stirring occasionally, until vegetables are very tender, about 1 hour. Cool, uncovered, and serve warm or at room temperature.
