Fibre promotes fullness and satiety by moving through the digestive tract slowly. It reduces calorie intake and helps to maintain a calorie deficit for weight loss. Therefore, eggplant can be a healthy alternative to higher-calorie ingredients. 

Helps Treat Anaemia 

WHO estimated that 1.92 billion people globally suffer from anaemia. Patients who have anaemia suffer from headaches, fatigue, depression, migraines, weakness, and cognitive malfunction. Eggplants contain a fair amount of copper and iron. Copper with iron assists in increasing the count of red blood cells. Eating foods that have iron will help in managing anaemia.

Helps Fight Cancer

Eggplant is rich in antioxidants. Investigations show bioactive components in eggplants help prevent cancer. Chlorogenic acid is an antioxidant found in eggplants that is antiviral and antibacterial and helps fight against cancer. Moreover, solasodine rhamnosyl glycosides (SRGs) are a unique plant compound found in eggplants that have anti-cancer properties.

Nevertheless, the majority of research now only involves tests on animals. More research is necessary to determine how eggplants could improve human heart health.

Risks of Overconsumption

The recommended amount of eggplants per day is less than 100 grams daily. One can get almost 7% to 10% of the daily fibre needs from one cup of eggplant. Overconsuming eggplants may have a few adverse effects. Such as:

Kidney Stones

Due to its high oxalate content, eggplant should be consumed in moderation by those who suffer from kidney stones. The crystal formations of calcium oxalates are extremely painful and inflammatory.

Allergic Reactions

Allergic reactions are one of the most frequent adverse effects of eggplant. Although it is uncommon, eating eggplant may induce anaphylaxis in certain people. Additional potential allergic reactions to eggplant include rashes or skin irritation, gastrointestinal pains, asthma, or trouble breathing. 

Solanine Poisoning

Eggplants naturally contain a poison called solanine. Vomiting, nausea, and sleepiness are all signs of solanine toxicity that can result from overconsumption. However, to reach potentially dangerous solanine levels, one would need to consume more than twelve whole eggplants (at least!) in a single sitting. 

Iron Deficiency

Iron is bound to nasunin, a kind of anthocyanin found in eggplant peels, which extracts iron from the cells. It may impair the body’s absorption of iron and result in a deficiency.


Overeating eggplants might result in solanine toxicity and allergies. The compound found in eggplant peels called nasunin, a kind of anthocyanin, binds to iron and extracts it from the cells. It can lower iron absorption and result in an iron shortage in the body. Eggplants naturally contain a poison called solanine. Vomiting, nausea, and sleepiness are all signs of solanine toxicity that can result from overeating. In addition, because of the oxalates they contain, kidney stones can also develop. Though uncommon, another potential eggplant side effect is an allergic reaction. It might trigger hives, rashes, skin irritation, anaphylaxis, swelling, and abdominal cramps. 

HealthifyMe Suggestion

If you aren’t a fan of eggplants, instead of cooking them separately, you can combine eggplants with other foods to improve their palatability. For example, a non-vegetarian could add cubes of eggplant along with root veggies while cooking a chicken stew or add eggplants with mince in a tomato base as seen in a Shepherd’s Pie. A vegetarian could make a brinjal spiced mash (bharta) and pair it with pooris or stuffed parathas rather than plain rotis or rice.

The Final Word

It’s no secret that eggplants are an excellent addition to almost any meal, and there are many different varieties to pick from. Eggplant’s high fibre content is an ideal way to support gastrointestinal health because fibre is essential to a balanced diet. There are other possible health advantages as well. But it’s also necessary to incorporate a range of veggies in your diet to ensure you are getting a variety of nutrients.
