Eggplant Nutrition Facts and Health Benefits (2024)

Eggplant (Solanum melongena) is a very popular and versatile ingredient in a variety of cuisines. The vegetable is believed to have originated in India. In South Africa and parts of Asia, eggplants are referred to as "brinjal." In the UK and Ireland, they are called "aubergine."

Eggplants are a member of the Solanaceae family, also known as nightshades. Other common nightshades are tomatoes, peppers, and potatoes. While these veggies are nutrient-dense, some people avoid them because they may cause inflammation, especially in those with certain types of inflammatory conditions, such as arthritis or psoriasis.

Eggplant Nutrition Facts

One cup of cubed raw eggplant (82g) provides 20 calories, 0.8g of protein, 4.8g of carbohydrates, and 0.1g of fat. Eggplant is a good source of fiber, manganese, and potassium. The following nutrition information is provided by the USDA.

  • Calories:20.5
  • Fat:0.1g
  • Sodium: 1.6mg
  • Carbohydrates:4.8g
  • Fiber:2.4g
  • Sugars:2.9g
  • Protein:0.8g
  • Manganese: 0.2mg
  • Potassium: 188mg


One cup of raw eggplant contains 4.8 grams of carbohydrate, about half of which comes from fiber (2.4 grams).There are also almost 3 grams of naturally occurring sugars in eggplant.

Eggplant is a low-glycemic food. The glycemic load of eggplant is estimated to be 1 for a single serving.


Eggplant is almost completely fat-free.


There is less than 1 gram of protein in a single serving of eggplant.

Vitamins and Minerals

Eggplant is not a significant source of most vitamins and minerals. However, the vegetable provides manganese (10% of daily intake) and small amounts of potassium, vitamin K, vitamin C, vitamin B6, niacin, copper, and magnesium.


Eggplant is a low-calorie, naturally fat-free source of complex carbohydrates with plenty of fiber. It also offers manganese and small amounts of potassium and vitamin K.

Health Benefits

People who regularly consume eggplant may take advantage of certain health benefits from the nutrients that it provides, such as fiber, phytonutrients, and anthocyanins.

Supports Bone Health

Eggplants are a good source of manganese, a mineral needed for several functions in the human body, including processes that keep bones healthy.

Manganese interacts with other nutrients like calcium and vitamin D to help maintain bone health. Researchers don't exactly know how much manganese plays a role, but animal studies have shown that manganese deficiency can impair bone formation and reduce bone mineral density. Manganese supplementation, on the other hand, can increase both bone mineral density and bone formation.

Reduces Cell Damage

Eggplants contain fairly high amounts of various types of phytonutrients, especially nasunin and chlorogenic acid, which may help protect cells from damage and lower the risk of heart disease.

Also, the skin of eggplants contains anthocyanins, which give them their purple hue. Anthocyaninshave been shown to have antioxidant power by combating oxidative stress. Research suggests that eating foods with anthocyaninsmay also help to fend off diseases, such as cardiovascular disease and cancer, and aid in health maintenance.

Benefits of Phytonutrients

Improves Digestion

The fiber in eggplant may help to keep your digestive system healthy. Fiber is the indigestible part of carbohydrates. It helps to regulatebowels by regulating food ingestion, digestion, absorption, and metabolism.

Most adults should consume about 25 to 38 gramsof fiber each day. One cup of raw eggplant provides about 10% of your daily fiber needs.

Reduces Risk of Disease

Studies have shown that those people who consume fiber-rich diets are at a reduced rate of cardiovascular disease. Other research has linked higher fiber intake to a decreased risk of diabetes and certain types of cancer.

Increasingly, plant-based diets are associated with better health and a reduced risk of chronic diseases like high blood pressure, diabetes, cardiovascular disease, or obesity. Eggplant can have a meat-like taste and texture, so many people use it as a meat substitute in plant-based recipes. However, unlike meat, it doesn't provide much protein.

Helps With Weight Maintenance

Plant-based diets and diets rich in fiber are associated with healthy weight maintenance and a reduced risk of obesity. And studies have shown that people who eat high-fiber diets tend to be at healthier weights.

Epidemiological and clinical studies have also demonstrated that dietary fiber intake is inversely related to metabolic conditions such as obesity and type 2 diabetes.


Allergies to nightshade foods like eggplant are rare, according to theAmerican Academy of Allergy, Asthma, and Immunology.But if you are allergic to one nightshade, you may have an allergic reaction to the others.

If you suspect an allergy to eggplant, seek the care of a qualified healthcare provider for personalized advice.

Adverse Effects

Some people avoid nightshades, like eggplant, to reduce inflammation in the body. One anti-inflammatory (AI) diet excludes nightshades and many other foods including wheat, corn, soy, dairy, and citrus. Those with inflammatory conditions such as psoriasis, rheumatoid arthritis, allergy, asthma, or autoimmunediseases might try this diet to help manage their condition. The diet has been studied with mixed results.

In a study investigating the effect of the AI diet on people with type 2 diabetes, researchers concluded that the diet did not affect markers of inflammation more than a control diet. But authors of a study investigating a version of the AI diet on people with inflammatory bowel disease found that it can improve symptoms and inflammation. Those researchers suggested, however, that more research is needed to fully understand the benefit.

Anti-Inflammatory Diet: Pros, Cons, and How It Works


Eggplants come in many shapes and sizes. Most of the eggplants that you see at the grocery store are globe eggplants (also called American eggplants). These are usually the most inexpensive and easy to find.

Italian eggplants look similar to the American eggplants but are smaller. Japanese eggplants are the same color as Italian and American eggplants but are smaller than those varieties. Chinese eggplants are similar to Japanese eggplants but are usually lighter in color. Indian eggplants are often called baby eggplants because of their tiny ball-shaped appearance.

Other types of eggplant include graffiti eggplant, little green eggplant, white eggplant, Thai eggplant, and fairytale eggplant.

When It’s Best

Eggplant is available all year long in most grocery stores (especially the common globe variety). Peak season is during the late summer to early fall.

When buying eggplant, choose an eggplant that is heavy for its size. The eggplant should appearplump, with smooth, shiny skin. Avoid eggplant with blemishes.

Storage and Food Safety

Store eggplant whole in the refrigerator. Keep it in the produce bag and place it in the vegetable bin for 7 to 10 days. Once cut, eggplant begins to deteriorate quickly, so do not slice into it until you are ready to cook with it.

You can freeze eggplant either cooked or uncooked. If wrapped in an airtight freezer bag, it should stay good in the freezer for up to 12 months.

How to Prepare

Some people eat eggplant with the skin on and some prefer to remove the skin before using it in recipes. It's a personal preference, but the skin can be tough, especially on larger eggplants. If you don't want to consume the skin, use a paring knife to remove it before slicing or cubing.

Many people also salt eggplant before cooking with it. Eggplants can become soggy if they are not salted before cooking. This is because they are filled with cells that contain water. Heat draws air out of the pockets and if the eggplant has not been salted, oil can seep into the pockets, making it soggy. A small amount of salt can draw water out of the cells, which causes the air pockets to collapse.

Some also say that salting eggplant removes some of the bitterness, but this is another personal preference. Japanese and Chinese eggplants tend to be less bitter and are less likely to need salting for flavor.

Eggplants can be breaded and fried, roasted, stuffed and baked, grilled, or cubed and added to savory recipes to provide some flavor and texture. There are countless ways to use this versatile and nearly fool-proof vegetable. It is nearly impossible to overcook an eggplant, but undercooking it will yield a chewy and sometimes bitter food.
