The eggplant is a staple vegetable in almost every Israeli kitchen – from fire-roasted salads to a perfect spread. Of course, behind the purple vegetable hides a particularly interesting nutritional world: Health benefits, unique antioxidants, surprising nicotine content, and also a variety of traditional dishes from all over the world.

Basic nutritional value: It contains only about 20 calories per 100 grams, and therefore is considered a diet-friendly food. The eggplant provides dietary fiber in a nice amount (about 3 grams per 100 grams), which contributes to proper digestion, balancing blood sugar levels, and also to a feeling of satiety that lasts over time.

In eggplant there is a variety of B-group vitamins, including B1 (thiamine) which is important for energy production and nervous system activity, and B6 (pyridoxine) involved in the activity of hundreds of different enzymes in the body. The eggplant also contains vitamin C, which is known as a central antioxidant and helps in protecting cells and strengthening the immune system. In terms of minerals: The eggplant provides potassium – a vital mineral for balancing blood pressure and heart muscle function, as well as manganese and copper, which play an important role in metabolism and the body's antioxidant system.

Unique antioxidants: The true wealth of the eggplant is actually found in its purple skin. The skin contains anthocyanins – natural pigments that give the plant its intense color and serve as powerful antioxidants. One of the main components studied is Nasunin, which is found in eggplant skin and is considered unique in protecting cell membranes from oxidation.

A study published in the
Journal of Agricultural and Food Chemistry
showed that an antioxidant substance found in the purple eggplant skin helps protect body cells from oxidative damage. Such damage is linked to premature aging and the development of chronic diseases, and therefore eggplant may have a unique contribution to health. A review in
Food Chemistry
found a link between eggplant consumption and a decrease in inflammatory markers and an improved blood lipid profile. An animal experiment (
Journal of Nutritional Biochemistry
) showed that eggplant skin extract significantly reduced cholesterol levels and decreased oxidative damage in blood vessels.

Fat absorption in cooking: Eggplants are known as "natural sponges" – during frying they absorb a very large amount of oil. As a result, a single eggplant slice can jump from 20 natural calories to more than 100 calories, depending on the amount of oil. This explains why dishes like moussaka or fried eggplant are considered high in calories. To enjoy the taste without overloading, the recommendation is to use other methods – grilling over fire, baking in the oven, or a light sear with an oil brush.

Nicotine content and effect on mood: Less known, but the eggplant contains small amounts of natural nicotine. It belongs to the Solanaceae family (like tomato and potato), all of which actually contain tiny amounts of nicotine. Does it have the same effect as smoking? The answer is unequivocally no.
To reach a nicotine amount equal to one cigarette – a person would have to eat about 9 kilograms of eggplants at once!

In a review published in the New England Journal of Medicine, the researchers emphasized that the nicotine content in vegetables does not constitute a health hazard, and it has no effect on mood or addiction. So if it affects... Then actually for the better. Not like smoking.

Sensitivities and side effects: Like other members of the Solanaceae family, eggplant can also cause sensitivity in some people. This usually involves discomfort in the digestive system – bloating, gas, or heartburn. There are also rare reports of a true allergy to eggplant, mainly in India, where it is one of the most common vegetables. However, for most people – eating eggplant is completely safe and involves no risk.

The eggplant in different cuisines around the world: Few vegetables have won so much fame in different cuisines as the eggplant. In the Middle East – the classic dishes are roasted eggplants with tahini (baba ghanoush), eggplant salad with chopped vegetables, or grilled eggplant slices. The combination with tahini provides protein, calcium, and unsaturated fats – which makes the dish richer and more balanced.


In Greece and Turkey: Moussaka is the most identified dish – layers of fried or baked eggplants, combined with meat, yogurt, or béchamel. The eggplant there is the base that holds all the flavors.
In India – a dish named "Baingan Bharta" includes a mashed roasted eggplant with intense spices, tomatoes, and onions.
In France: The eggplant appears in the dish "Ratatouille", alongside zucchini, peppers, and tomatoes, and it also grants the colorful variety a depth of flavors.
The common denominator of all these dishes is the ability of the eggplant to "absorb" flavors – it itself is relatively neutral, but integrates wonderfully with olive oil, spices, yogurt, or tahini.

Tips for choosing a fresh eggplant: To enjoy the taste at its best, it is important to know how to choose correctly.

  • Shiny and tight skin – indicates freshness.
  • Green stem – is a sign that the eggplant did not sit for a long time in the warehouse.
  • An eggplant that looks heavy relative to its size, is usually juicy and has fewer seeds, a light eggplant – fresher.
  • Small eggplants tend to be less bitter – and therefore are particularly suitable for salads and roasting.
  • It is advisable to avoid eggplants with brown spots or soft indentations – these are signs of flaws or too long storage.
