What the Research Says

Nasunin and NeuroprotectionModerate Evidence

Studies indicate that nasunin, an iron-chelating phytonutrient, may help prevent cellular oxidative damage, which is a known factor in age-related cognitive decline.

Diabetes ManagementLimited Evidence

While eggplant is low-glycemic, most research on its blood-sugar-lowering effects has been conducted in animal models or in vitro, requiring more clinical human trials to confirm efficacy.

How to Cook It

Preparation Tips

  • •Salt the sliced eggplant for 20 minutes before cooking to draw out moisture and remove any potential bitterness.
  • •Use a brush to lightly coat with oil rather than letting it soak up large amounts, which helps keep the dish lighter.
  • •Roast whole until the skin collapses to achieve the creamiest texture for dips like baba ganoush.

Flavor Pairings

  • •Garlic and Tahini
  • •Fresh Tomatoes and Basil
  • •Cumin and Coriander
  • •Lemon juice and Parsley

Storage Tips

  • •Keep eggplant away from ethylene-producing fruits like bananas to prevent rapid softening.
  • •Do not wash until ready to use, as excess moisture on the skin can lead to premature decay.

How to Pick the Best One at the Store

Selection Tips

  • •Look for skins that are tight, glossy, and free of blemishes or brown spots.
  • •The eggplant should feel firm and heavy for its size, indicating high water content and freshness.
  • •Gently press the surface; if the flesh springs back immediately, it is perfectly ripe.
  • •Ensure the green stem cap is vibrant and not shriveled or dry.
