Egg of the liver fluke develops into cercariae in snails in rivers and ponds, and then parasitizes in fish. If raw river fish is eaten, the liver fluke will enter the human body and develop into an adult, which can cause cholangitis in the human body, and even develop into cirrhosis. According to a survey of patients with cholangitis in a certain hospital: among them, those who love to eat raw fish slices account for about 60%, and among patients with cirrhosis, those who love to eat raw fish account for 50%.
Two: Do not eat raw crabs and lobsters
Raw crabs carry metacercariae of lung flukes and Vibrio parahaemolyticus, while lobsters are intermediate hosts of lung flukes. After eating raw crabs and lobsters, lung flukes enter the human body, causing lung damage, and in severe cases, it can cause intestinal inflammation or intestinal edema and congestion. According to statistics, among outpatients, eating raw crabs and lobsters has caused lung damage in more than 4,000 people, intestinal inflammation in more than 3,000 people, and intestinal edema and congestion in more than 2,000 people.
Three: Do not eat raw water chestnuts
Often eating raw water chestnuts allows the Fasciolopsis buski to enter the human body and attach to the intestinal mucosa, which can cause intestinal ulcers, diarrhea, or facial edema. According to a report from a certain hospital last March, among outpatients, more than 400 people were invaded by Fasciolopsis buski due to eating raw water chestnuts, leading to intestinal ulcers, 158 people suffered from diarrhea, and 15 people had facial edema.
Four: Do not eat raw eggs
The avidin in egg white binds with biotin in the intestine, which will hinder the human body's absorption of biotin. Raw eggs often contain Salmonella, which can cause vomiting and diarrhea.
Five: Do not eat fresh daylilies raw
Fresh daylilies contain colchicine, which forms toxic colchicine oxide in the human body. It is extremely toxic, and 3-20 milligrams can be fatal.
Six: Do not eat fresh raw wood ear mushrooms
Fresh wood ear mushrooms contain porphyrin photosensitive substances. After eating fresh raw wood ear mushrooms, it can cause solar dermatitis, and in severe cases, it can cause skin itching, edema, and pain.
Seven: Do not eat raw honey
When bees make honey, they often collect some poisonous pollen. After these poisonous pollens are brewed into honey, people who eat raw honey are prone to poisoning. In addition, honey is easily contaminated by bacteria during harvesting, transportation, and storage. Therefore, raw honey is not edible.
Eight: Do not drink raw soy milk
Soy milk is delicious and its nutritional value is no lower than milk. However, drinking unboiled soy milk can cause systemic poisoning. Because raw soy milk contains some harmful ingredients—antitrypsin, phenolic compounds, and saponin. Antitrypsin affects the digestion and absorption of protein; phenolic compounds can make soy milk bitter and fishy; saponin stimulates the digestive tract, causing vomiting, nausea, and diarrhea, thereby destroying red blood cells, producing toxins, and causing systemic poisoning.
Nine: Do not eat raw beans
Beans include lentils, kidney beans, string beans, sword beans, and green beans. Eating beans can easily cause poisoning because beans contain a toxic protein called "lectin". This substance is most abundant in mature or older beans. Beans should be boiled or heated over high heat for more than 10 minutes to remove "lectin". When stir-frying beans or using them as a filling, they should be fully heated. When eating cold mixed beans, they should also be cooked for 10 minutes.
Ten: Do not eat raw white sugar
Mites often parasitize in white sugar. Eating raw white sugar can easily cause acariasis. Mites are small insects covered in hair that are invisible to the naked eye and reproduce quickly in sugar. If mites enter the gastrointestinal tract, they will cause abdominal pain, diarrhea, and form ulcers. If they enter the lungs, they can cause hemoptysis and asthma. If they enter the urethra, they can cause urinary tract inflammation. Therefore, it is best not to eat white sugar raw. It should be heated before consumption (generally, heating to about 70°C for 3 minutes is sufficient).
