Property –
Raw aubergine has a bitter taste that is diluted with cooking, which also makes the vegetable more digestible and enhances its flavor. On the other hand, aubergine has the property of absorbing dietary fats, including oil, very well, allowing the preparation of very rich and tasty dishes. For these reasons the aubergine is preferably consumed cooked. Normal cooking is not able to completely eliminate solanine, which degrades completely at much higher temperatures (around 243 ° C); however, this is not a problem, because in aubergines the content of solanine (α-solanine, solasonine and solamargine) is equal to 9-13 mg / 100 g of fresh weight, well below the quantity considered acceptable for vegetables (20 –25 mg / 100 g of fresh weight).
Furthermore, the soluble fibers present in eggplants help to keep the cholesterol level in the blood under control. Antioxidants and vitamins of group B bring benefits to the functioning of the metabolism, potassium is an ally of heart health and in the skin there are many anti-tumor, anti-aging, anti-inflammatory and protective molecules against neurodegenerative diseases (specifically, anthocyanins)
Among the contraindications it should be remembered that, as mentioned, solanine is contained in aubergines, a compound that is dangerous to health but which does not seem to trigger toxic effects following food use, especially cooked, of this vegetable.
Furthermore, there are no interactions between the consumption of aubergines and the intake of drugs or other substances. In case of doubt, however, it is advisable to ask your doctor for advice.
