Honestly, most people look at an eggplant and see a sponge. They think it’s just a vessel for oil or a slightly rubbery filler for a Parmesan bake. But if you actually look at eggplant nutritional information, you’ll realize this nightshade—which is technically a berry, by the way—is doing a lot more heavy lifting than your average side dish. It’s low-calorie. It’s dense with specific phytonutrients. And it has a glycemic profile that makes it a literal superstar for blood sugar management.
Stop calling it a vegetable. It's a fruit. It belongs to the Solanaceae family, sharing a lineage with tomatoes and potatoes. But unlike its cousins, the eggplant (or aubergine, if you're feeling fancy) carries a very specific set of antioxidants that you won't find just anywhere else in the produce aisle.
The Macro Breakdown: It's Mostly Air and Water
Let’s get the basics out of the way. One cup of raw eggplant (about 82 grams) is basically a rounding error on your daily caloric intake. We’re talking 20 calories. That’s it. You get about 5 grams of carbohydrates, 3 of which are fiber. It has almost zero fat and a negligible amount of protein (around 1 gram).

Why does this matter? Because volume eating is a real thing. If you’re trying to manage weight without feeling like you’re starving, the eggplant nutritional information profile is your best friend. You can eat a massive portion of roasted eggplant for the same caloric cost as a single bite of a bagel.
However, you have to be careful. Because eggplant is porous, it acts like a sponge. If you fry it in a pool of olive oil, that "low calorie" status evaporates instantly. It’ll soak up every gram of fat you give it. To keep the nutrient density high, you’ve got to master the roast or the steam. Salt it first. Let the water sweat out for 20 minutes. This collapses those air pockets so the fruit doesn't drink the oil bottle dry.
The Purple Power: Nasunin and Anthocyanins
The skin is where the magic happens. If you’re peeling your eggplant, you’re throwing away the best part. That deep, royal purple color comes from anthocyanins. Specifically, a potent compound called nasunin.
Nasunin is a major player in the world of antioxidants. Research, including studies cited by the National Institutes of Health, suggests that nasunin is an iron chelator. It helps protect the lipids (fats) in brain cell membranes from damage. Basically, it’s brain food. It keeps your cell walls flexible and functional so nutrients can get in and waste can get out.
Beyond the brain, anthocyanins are famous for cardiovascular support. They help with endothelial function—the way your blood vessels dilate and contract. If you want your heart to work less to move blood through your body, eating purple stuff is a pretty solid strategy.
What about the "Toxic" Solanine?
You might have heard people whisper that eggplants are inflammatory because they’re nightshades. This is mostly overblown. Yes, eggplants contain solanine, a natural alkaloid. In massive, concentrated doses, solanine can be toxic. But you would have to eat an ungodly amount of raw eggplant to even feel a twinge of a stomach ache. For the vast majority of people, the anti-inflammatory benefits of the antioxidants far outweigh any theoretical risk from alkaloids. If you have a specific autoimmune sensitivity, sure, be cautious. Otherwise? Eat the purple fruit.
Blood Sugar and Fiber: The Metabolic Win
When we talk about eggplant nutritional information, we have to talk about manganese and fiber. One cup gives you about 10% of your daily manganese requirement. Manganese is a trace mineral that’s essential for bone health and metabolism.
Then there's the fiber. It’s mostly soluble fiber, which is the kind that turns into a gel-like substance in your gut. This slows down the absorption of sugar into your bloodstream. If you’re pre-diabetic or just trying to avoid that 3:00 PM energy crash, adding eggplant to your lunch is a tactical move. It lowers the overall glycemic load of the meal.
- Calories: 20
- Fiber: 3g (11% DV)
- Manganese: 10% DV
- Potassium: 5% DV
- Folate: 5% DV
- Vitamin K: 4% DV
The potassium levels are decent, too. It’s not a banana-level powerhouse, but at 188mg per cup, it contributes to that electrolyte balance that keeps your blood pressure from spiking. It’s a quiet overachiever.
Common Misconceptions: Bitterness and Nicotine
Did you know eggplants contain nicotine? It’s true. It’s a tiny, tiny amount—about 100 nanograms per gram of eggplant. To get the nicotine equivalent of a single cigarette, you’d have to eat about 20 pounds of eggplant in one sitting. So, no, you won't get a "buzz" from your Moussaka, and you won't get addicted to Baba Ganoush.

As for the bitterness, that’s usually a sign of age. Smaller, younger eggplants are sweeter. The big, "globe" varieties you see in standard grocery stores can get bitter if they’ve been sitting in cold storage too long. Look for skin that’s shiny and tight. If it’s dull or wrinkled, the nutritional quality is starting to degrade, and it's going to taste like a penny.
How to Maximize the Nutrients
To actually get the most out of the eggplant nutritional information, you need to think about bioavailability. Some vitamins are fat-soluble (like Vitamin K), meaning you actually need a little bit of healthy fat to absorb them.
Don't boil it. Boiling leaches the water-soluble vitamins (like B6 and Folate) right into the pot, and unless you’re drinking the eggplant water, they're gone. Grilling or roasting at high heat (around 400°F or 200°C) caramelizes the natural sugars and keeps the fiber intact.
- Keep the skin on. No exceptions unless the recipe absolutely demands a puree.
- Use a "dry" prep. Salt the slices, wait for the beads of water to appear, and pat them dry.
- Pair with Vitamin C. Eating eggplant with lemon juice or tomatoes helps your body absorb the non-heme iron present in the plant.
Real World Impact: Heart Health
There was a study published in the journal Food & Function that looked at how eggplant juice impacted cholesterol levels in animals. While human trials are always more complex, the results showed a significant decrease in LDL (the "bad" cholesterol) and triglycerides. The researchers pointed back to those anthocyanins and the fiber content. While you shouldn't swap your statins for a side of eggplant, it’s a powerful dietary tool for long-term maintenance.
Actionable Steps for Your Next Meal

- The "Steak" Method: Slice a large eggplant into 1-inch thick rounds. Brush lightly with avocado oil (high smoke point), sprinkle with smoked paprika and garlic powder, and roast until the center is creamy.
- The Dip Strategy: Roast a whole eggplant until it collapses. Scoop out the insides and mix with tahini, lemon, and garlic. You've just made a nutrient-dense Baba Ganoush that's loaded with healthy fats and fiber.
- The Pasta Swap: Use cubed, roasted eggplant to bulk up a pasta sauce. You get the volume and the "chew" without the heavy carb load of extra noodles.
The reality of eggplant nutritional information is that it’s a low-risk, high-reward food. It’s one of the few things you can eat in massive quantities that actually helps your heart, your brain, and your waistline simultaneously. Next time you're in the produce section, look for the heaviest, shiniest purple one you can find. Your cells will thank you.
Summary of Daily Value (DV) Contributions
One medium eggplant (approx. 500g) provides a surprising amount of your daily needs. It covers nearly 40% of your fiber, 35% of your manganese, and 15% of your potassium. It’s a dense package wrapped in a low-calorie skin. For those tracking micronutrients, it's also a respectable source of copper and B-vitamins, which are crucial for energy production.
Ready to use this? Start by incorporating eggplant into two meals this week. Don't peel it, don't deep fry it, and watch how it changes your satiety levels. You’ll feel fuller longer, and you’ll be fueling your brain with the kind of antioxidants that are hard to find elsewhere.
