has been popular among Chinese people since ancient times. Many proverbs have been summed up based on long-term observation, production and life practice. Their contents are about agriculture, forestry, animal husbandry and fishing, weather phenology, daily diet, four seasons health preservation and inclusiveness. Before and after the frost every year, there is a popular saying "you can't eat frosted eggplant". Is this true? Let the old yellow calendar answer it for you.
after the frost, the saying that "frosted eggplant can't be eaten" has been widely spread again. To understand the meaning of this proverb, we must first understand a substance called "solanine". Solanine is a secondary metabolite of Solanaceae plants. It is a substance produced by plants in order to protect themselves. It can inhibit the growth and reproduction of plant pathogens and resist insect invasion.and
solanine are also important bioactive components in fruits. They have certain effects of strengthening heart and reducing blood pressure, anti-cancer, relieving asthma and inhibiting microorganisms. The various health functions of eggplant are closely related to solanine. However, it is worth noting that excessive intake of solanine will cause discomfort to the human body, resulting in discomfort reactions such as nausea, vomiting and diarrhea. The origin of,
and "frost beaten eggplant can't be eaten" in the past, eggplant grew in the field. In autumn, the content of solanine in eggplant increased, and the water content of frost beaten eggplant decreased, which will also cause the increase of solanine. Excessive consumption will lead to discomfort, which is also the source of the saying that "frost beaten eggplant can't be eaten". In fact, this proverb is to tell you that in the past, you can't eat too much frosted eggplant. The eggplant cultivated byand
modern technology can be eaten after frost, but the current cultivation technology has changed greatly. Today's eggplant grows in the greenhouse, and the influence of season on the content of solanine in eggplant is less and less obvious. Therefore, for modern people, they can still eat eggplant after frost.and
it should be noted that solanine mainly exists in the pulp with less peel content, but the darker the peel color, the higher the solanine content in the pulp. In addition, the content of solanine in immature eggplant is higher than that in mature eggplant. Therefore, we should eat as little as possible. Eating half a catty of mature eggplant a day will not cause any trouble.and

Eggplant is also rich in bioflavonoids, with strong antioxidant capacity, which can help prevent diseases such as hypertension, coronary heart disease and arteriosclerosis. The saponins can reduce cholesterol.and
