Core Tip: Many fruit peels can be beneficial to your health when eaten directly. However, for some fruits, eating them with the peel can not only fail to promote health but may also damage bodily functions.
Most fruit peels can be eaten along with the flesh, such as cucumber peels and apple peels, which are very effective in regulating blood lipids and high blood pressure. Therefore, in daily cooking, it is best not to peel these fruits, as eating them with the peel is more nutritious. However, some fruits are not suitable to be eaten with the peel. Let's take a look.
Sweet potato peel. Sweet potato peels contain too much alkali, and excessive consumption can easily lead to indigestion. Especially when the skin has black or brown spots, it should not be eaten, as consuming such peels can damage the liver and even cause poisoning.
Potato peel. Toxins that can grow on potatoes are mainly concentrated in the sprouts and green parts. If the potatoes have not sprouted or turned green, then the potato peel concentrates most of the potato's toxins--glycoalkaloids. When these toxins accumulate in the body to a certain extent, they can cause poisoning symptoms such as vomiting, dizziness, and diarrhea. Some families like to cook beef with potatoes on the skin, which poses potential health risks.
Ginkgo peel. This is what we commonly call ginkgo peel. The ginkgo peel contains toxic substances such as "ginkgolic acid," "ginkgolic acid hydrogenation," "ginkgolic acid hydrogenation sub-acid," and "ginkgol," which can damage the central nervous system and cause poisoning after entering the human body. Additionally, even cooked ginkgo flesh should not be consumed in large quantities.
Persimmon peel. Tannic acid is a substance that affects human stomach acid secretion and then forms precipitates in the body. These substances can store toxins and cause damage to the body. When persimmons are unripe, these substances are mainly concentrated in the flesh, and when ripe, they are mainly concentrated in the skin. Therefore, when choosing persimmons in the autumn, you should choose ripe ones and peel them before eating.
Water chestnut peel. Water chestnuts, which we commonly call water chestnuts in daily life, often grow in paddy fields. Their peels can accumulate harmful biological waste and chemicals. In addition, water chestnut peels also contain parasites. Eating unwashed water chestnut peels can lead to illness. Furthermore, it should be noted that water chestnut peels contain a lot of starch, so diabetic patients should be cautious when consuming them.
