1. Will eating cherries cause iron poisoning? How much can I eat to get iron poisoning?
Cherry does contain iron, about 0.3-0.4 mg per100g. The daily iron intake of adults is 10 mg -45 mg. According to this amount, adults need to eat at least 10 kg if they want to eat cherries to the point of "iron poisoning". Although cherries are free now, it is not easy to eat 10 kg, so it is less likely to be "iron poisoned" by eating cherries.
Second, will eating cherries cause cyanide poisoning?
Cherry contains a certain amount of cyanoside (qíng dài), which will form some cyanoside compounds after it reacts with gastric acid. When these compounds are eaten in excess, they are prone to acute poisoning symptoms.
Specifically, cyanoside poisoning is that cyanoside is decomposed by saliva to produce a highly toxic substance called cyanohydrogen acid. It can combine with iron-containing respiratory enzymes in human tissues and cells, making cells unable to use oxygen, leading to hypoxia symptoms in human body. Light dizziness, headache, nausea, weakness; In severe cases, vomiting, diarrhea and unconsciousness; Serious people are life-threatening.
According to the paper on cyanide in food published in the 5th issue of China Journal of Food Hygiene in 2008 by the Food Safety Center of Hong Kong Food and Environmental Hygiene Department, the Institute of Food Research and Laboratory and the School of Public Health of Peking University Medical School, the dose of cyanide that can cause adult death is 0.5-3.5mg per kilogram of body weight. The detection limit of cyanide in Analytical Method of Food Hygiene Standard is 0.0 15mg/kg, and the limit of cyanide in Hygienic Standard for Drinking Water is 0.05 mg/L..
Cyanoside of cherries (qíng
Dài) Where does it mainly exist? Mainly in the kernel of cherries, the "cyanoside" in each gram of cherries is only about tens of micrograms after being converted into hydrocyanic acid, and the dose of hydrocyanic acid causing human poisoning is about 0.5-3.5 milligrams per kilogram of body weight (1 mg equals 1000 micrograms). Assuming that each gram of cherry kernels can "produce" 50 micrograms of cyanuric acid, an adult weighing 60 kilograms will eat 600-4200 grams of cherry kernels before poisoning symptoms may occur. Therefore, as long as you don't bite the nucleolus, eating cherries normally will not cause cyanoside poisoning. (Of course, don't worry too much about biting one or two nucleoli occasionally, and it's okay if the main amount is not reached.)
Third, the abdomen suddenly feels colic. What is the "blood in the stool"?
Because cherries are rich in anthocyanin, which is a water-soluble natural pigment, eating too much may make it difficult for the body to digest and absorb, and it will be directly excreted from feces, resulting in bloody stool and hematuria. In addition, eating too much will stimulate the stomach and intestines, which may easily lead to abdominal pain, diarrhea, vomiting and other symptoms. "Bloody stool" should be "false bloody stool" dyed with fruit red pigment, that is, "red jam-like stool".
4. How many cherries should I eat that day?
Cherry is a warm fruit. Even if someone eats too many cherries and is not poisoned, they should not eat too much. Eating too much is prone to physical discomfort such as excessive internal heat and nosebleeds. Therefore, people suffering from cough, fever, asthma and gastric ulcer should not eat cherries. For normal people, it is advisable to take 5 or 6 capsules a day, but not more than 10 capsules at most.
