Many people think that there are a lot of nutrients in fruit and vegetable skin, so they should be eaten, but some fruits and vegetables must be peeled when they are eaten, otherwise it is easy to cause poisoning. What are the fruits that must be peeled before they can be eaten? The following Xiaobian will give you an introduction.
ginkgo:
The white peel contains toxic substances such as "gluconic acid", "hydrogenated ginkgoic acid," "hydrogenated ginkgo-acid," and "glycol," which can damage the central nervous system and cause poisoning. In addition, cooked ginkgo meat should not eat too much. Before eating the ginkgo, be sure to use hot water to blanch the outer red soft film and core (green germ). Adults eat up to 10 capsules per day and it is best to eat cooked food.
è¸è :
Commonly found in paddy fields, alfalfa can accumulate harmful and toxic biological excreta and chemicals. In addition, parasites are also contained in the fleas. If unwashed fleas are eaten, they can cause diseases. Raw or cooked food must be peeled.
Green beans and kidney beans:
Their toxic components are mainly saponins and trypsin inhibitors. When cooking, they should be cooked first, then removed, and cooked with seasoning and seasoning to remove toxicity.
broad bean:
The lack of 6-phosphate glucose deoxygenase in the body's red blood cells, hemolytic jaundice after eating beans, also known as broad bean disease. The disease is hereditary. Therefore, people with a family history should go to the hospital for examination and avoid eating broad beans.
sweet potato:
Sweet potato grows underground for a long time, and its epidermis is in direct contact with the soil, absorbing many harmful substances. And sweet potato skin contains more alkali, eating too much can cause gastrointestinal discomfort. In particular, sweet potatoes baked with coke are susceptible to the deposition of sulfur dioxide harmful substances in the skin, which may increase the risk of cancer.
potato:
Potato skin contains "glycoalkaloids", which can cause poisoning when accumulated in the body. Because the poisoning caused by it is a chronic poisoning, the symptoms are not obvious and therefore often overlooked. Potato roast beef, due to the different stomach acid concentrations required for digestion of these two foods, will prolong the residence time of food in the stomach, and elongate the time of gastrointestinal digestion and absorption, causing gastrointestinal discomfort. Therefore, it is best to eat potatoes peeled, in particular to cut the net has been turned green.
persimmon:
When the persimmon is immature, tannic acid is mainly present in the persimmon, and the mature tannin is concentrated in the persimmon. After the citric acid enters the human body, under the action of stomach acid, it will cooperate with the protein in the food to form a sediment - persimmon stone, and save toxins, causing a variety of diseases. When the persimmon is made into a persimmon, it is peeled, so the shell of the persimmon can be eaten with confidence.
Bright fruit:
All brightly colored skins should be eaten after being peeled because their skins are rich in “flavonoidsâ€. This chemical substance enters the human body and is degraded by the bacteria of the intestine to become dihydroxybenzoic acid and so on. It has a strong inhibitory effect on the thyroid gland.
In addition, although some fruit and vegetable skins are non-toxic, they contain too much crude fiber and may cause damage to the gastrointestinal tract. In addition, because fiber can stimulate intestinal peristalsis, some people suffering from gastrointestinal diseases, such as gastric ulcers, gastritis and various chronic enteritis patients, etc., must eat less fruit skin, so as not to make the disease worse.
