What Are The Health Benefits Of Eggplant?

1. May Promote Heart Health

Eggplants are said to possess antioxidant properties that may help promote heart health (2).

A study conducted by the University of Connecticut School of Medicine found that raw and cooked eggplant had cardioprotective properties. Nasunin, a polyphenolic component in eggplant, is beneficial for the heart (3).

Another study conducted on hypercholesterolemic (high cholesterol) rabbits found that eggplant juice may lower plasma and aortic cholesterol levels (4). Also, daily ingestion of eggplant could control high blood pressure in stressed individuals (5).

2. May Control Blood Sugar Levels

Eggplant is a rich source of fiber and low in soluble carbohydrates. It can help improve blood sugar control and regulate the absorption of glucose. In vitro studies of eggplant found that the phenolics in this vegetable act as inhibitors of enzymes involved with type 2 diabetes (6).

A study conducted by the German Institute of Human Nutrition found that dietary fiber consumption and its metabolic effects may help prevent diabetes. Fiber can slow down the absorption of sugar and control the blood sugar levels (7).

The polyphenols in eggplant may help control blood sugar levels (8).

3. May Reduce Cancer Risk

Eggplants may play an important role in cancer prevention. Extracts found in the eggplant peel are rich in solasodine rhamnosyl glycosides (SRGs). These compounds have cancer-fighting properties and may help treat skin cancer (9). A study conducted by the Australasian Medical Research found that the SRGs may induce cancer cell death (10).

Another study conducted by the University of Queensland found that a standard mixture of solasodine glycosides has been shown to be effective in the treatment of malignant and benign human skin tumors (11).

4. May Improve Cognitive Function

The phytonutrients in eggplants may protect the brain cell membranes from damage. They can also facilitate message transfer from one cell to another, thus preserving memory function.

Free radicals in the brain may be responsible for neural degeneration, Alzheimer’s, and dementia. Nasunin, the potent antioxidant in eggplant peels, may inhibit neural issues by scavenging these free radicals. This improves brain function and reduces the risk of neural ailments (12), (13).

5. May Aid Weight Loss

Is eggplant good for you if you are trying to lose weight? Yes, because it has high water content and is low in calories. This makes it ideal for people who want to reduce weight. The spongy texture of the vegetable facilitates these characteristics.

Hence, you must consume eggplant in its natural form as much as possible. The vegetable also has a high fiber content. The fiber boosts satiety and may help with weight loss (14). Anecdotal evidence suggests that it may also help improve digestion and metabolism. However, further studies are warranted to support this claim.

6. May Promote Eye Health

Eggplant is rich in lutein (15). The antioxidant may prevent age-related macular degeneration, which is the main cause of blindness and vision impairment (16). More long-term research is needed to understand the potential vision-protective effects of eggplant in humans.

7. May Enhance Bone Health

Eggplant may help improve bone mineral density and reduce the risk of osteoporosis (17). This vegetable contains nutrients like calcium, magnesium, and potassium that help promote bone strength (17), (18).

8. May Help Treat Anemia

The world has seen an unbelievable surge in the number of people with anemia over the last two decades. As per the WHO, a whopping 1.62 billion people today are affected by anemia (19).

Iron deficiency is one of the root causes of anemia, which has symptoms such as headaches, weakness, and difficulty concentrating (20). Therefore, doctors suggest a diet rich in iron to combat anemia.

Talking about eggplant nutritional value, it contains around 0.2 mg of iron per 100 grams. This nutritional vegetable is also rich in copper (about 0.173 mg in 100 grams) (18). These two minerals work together effectively to aid the proper production and distribution of RBCs, thus boosting the energy and hemoglobin levels (21).

9. May Prevent Birth Defects

Eggplants contain folic acid that is essential for pregnant women (22). The intake of a folic acid-rich diet may help prevent birth defects. Folate deficiency leads to abnormalities in both mothers and fetuses (23).

10. May Improve Skin Health

Eggplants are rich in vitamins, minerals, anthocyanins (natural plant compounds), and antioxidants. Anecdotal evidence suggests that these may help improve skin glow and help slow down aging. However, there is no scientific evidence to prove this claim.

Including eggplant in your diet is easy. In the following sections, we have discussed how to prepare and use brinjal in your diet.

What Is The Best Way To Prepare An Eggplant?

Eggplants are versatile, low-calorie vegetables. They have smooth, glossy skin and are purple. They have a slightly bitter taste. Soaking an eggplant in salt will draw out the moisture and also the compounds that contribute to the bitter taste. Also, this process will reduce oil absorption during cooking.

To do this:

  1. Always use a stainless steel knife to cut an eggplant. Carbon steel can react with the nutrients present in the eggplant and make the vegetable go black.
  2. Have the eggplant with its skin to enjoy complete nutrition.
  3. Cut the eggplant into the required size and shape. Sprinkle some salt over it and let it sit for at least 30 minutes. This will reduce its water content and make it absorb less oil while cooking.
  4. Salting eggplants will also help reduce their bitter taste to some extent. Rinse eggplants after you have salted them. This will help remove the excess salt from them.
  5. If you choose to bake the eggplant as a whole, make sure you pierce a lot of small holes on the skin with a fork. This will help the steam to pass through and escape. After baking, pass a knife through the eggplant. If it passes through easily, it is ready to be eaten.

Eggplants have a few risk factors associated with them. Excess consumption of eggplant may lead to side effects, such as allergies, solanine poisoning, and oxalate kidney stones.

  • May Cause Allergies

Eggplants belong to the nightshade family of vegetables that are associated with allergic reactions.

In very rare cases, they may cause allergic reactions in some people due to a specific lipid transfer protein (24). The symptoms include difficulty in breathing, swelling, and hives. In rare cases, eggplant may also cause anaphylaxis (a hypersensitive condition). If you experience any allergic reactions, stop eating eggplant and consult a doctor.

Insufficient Information For

  • May Disrupt Iron Absorption

Nasunin is an anthocyanin in eggplant peels that binds with iron and removes it from cells. In other words, it chelates iron (25). It may reduce iron absorption. Though more research is warranted in this regard, it is better if people with low iron levels avoid eggplants.

  • May Cause Solanine Poisoning

Solanine is the natural toxin found in eggplants. Excess intake of eggplants may cause vomiting, nausea, and drowsiness (26).

Consuming eggplants in low-to-moderate levels may not cause any harm. However, consult a health care professional in case of any emergency.

  • May Increase Risk Of Kidney Stones

Eggplants contain oxalates, which may increase the risk of kidney stones in some people. However, there is insufficient data available. If you have a risk of kidney stones, stop use and consult your doctor.
