Eat Seasonal

Eggplant, also commonly known as aubergine or guinea squash, is available year-round in Hong Kong. Thanks to the warm and humid climate in the nearby tropical countries, eggplants can be grown all year long in those regions and allow a constant supply to Hong Kong. In other parts of the world, eggplant is a summer vegetable, which botanically is a fruit, mostly found in summer and early fall. Most of us would recognize the dark purple color and long oval shape of eggplants, but they can come in many other different colors and sizes as well, such as light purple, white and green. Eggplants are vulnerable and do not last long, only for a few days in the fridge, as they are sensitive to light, heat and cold. Store whole eggplants wrap in paper towel or in a reusable container before putting into the crisper drawer of the fridge to make sure they don’t get too cold and go bad.


Eggplant is a common ingredient in both western and eastern cuisines. Ratatouille, stuffed eggplant, grilled eggplant, eggplant tempura, braised eggplant with spicy minced pork are some popular dishes from different cultures. The unique purple color of this summer veggie is an indicator of its abundant nutrient content.

Being one of the rare natural foods that comes in a dark purple color, eggplant’s special color comes from a higher concentration of anthocyanins which is an antioxidant that protects our cells from free radical damages and may have beneficial effects on our mental health. As a vegetable, it is not surprising that eggplant is one of the contributors of the dietary fibre we have in our diet, providing 2.5g (9% daily value) dietary fibre in one cup cooked eggplant (99g). Insoluble fiber helps keep things moving through our digestive tract quickly and therefore plays a role in preventing constipation and hemorrhoids, while soluble fiber helps manage blood sugar and cholesterol levels and increases satiety to support weight loss. Keeping the peel is a good way to retain the healthful nutrients, as anthocyanin is mainly found in the purple skin only and dietary fiber is also more abundant in the peel.

When preparing eggplant, especially in Asian ways, be cautious about the amount of oil we use in cooking. The spongy flesh of eggplant can absorb a large amount of oil and result in a high calorie dish which is not favorable to people who are managing their weight. Steaming and baking may be healthier cooking methods, but we still need to pay attention to the toppings or stuffing added to the dish.

Let’s enjoy this summer vegetable to add the hard-to-get purple color in our diet and get the valuable nutrients.


Eggplants have both a small water footprint and a low carbon footprint that are similar to many other plant-based ingredients. Interestingly, eggplants are always sold unprocessed without much packaging, and this makes eggplant greener and better to our environment. By choosing foods that are less processed and uses less packaging are also good ways to reduce our impacts on the planet.
