How to eat eggplant is the most nutritious and healthy?

Mashed potatoes are the healthiest. The heating time of tomato sauce is the shortest, and it only needs to be steamed on high fire, with the least nutritional loss. Secondly, mashing tomatoes uses the least oil. After the steamed eggplant is mashed, just pour some sauce on it. Finally, the eating method of mixed tomato sauce is the most complete in nutrient absorption, because it does not need to peel off eggplant skin, which contains a lot of bioactive substances.
