"Fresh Broad Beans
allergic hemolytic syndrome
"Fresh fungus" cannot be eaten,
Seriously, it can cause skin necrosis and induce skin cancer.”
"Unripe tomatoes are poisonous if eaten
Long-term consumption may cause stomach or bowel cancer”
"Lentils are inedible and cause cancer"
……
So are the above statements true?
Let's find out together today
Can fresh broad beans induce allergic hemolytic syndrome?
Internet rumors: Some people lack enzymes in their bodies. Eating fresh broad beans will induce allergic hemolytic syndrome. If there is no timely rescue, it will even lead to death.
Acute hemolytic anemia caused by some special groups (people with glucose-6-phosphate dehydrogenase deficiency) after eating broad beans (fresh, dry) or broad bean products (soy sauce, tofu, etc.) ", which is a type of erythrocyte glucose-6-phosphate dehydrogenase deficiency (G-6-PD enzyme deficiency), which often occurs in early summer.
It is worth noting that not everyone who eats broad beans will have such a disease.
For Glucose-6-Phosphate Dehydrogenase Deficiency, a disease that affects red blood cells, "G-6-PD enzyme" is a red blood cell enzyme that is a key in the red blood cell glycolytic pathway Enzyme substances, its deficiency can cause red blood cells to shorten the lifespan and structural damage after being stimulated by certain foods, drugs or chemicals, that is, "hemolysis".
From a scientific point of view, only a small number of people suffering from "G-6-PD enzyme deficiency" eat broad beans; for patients with "broad bean disease", it is not always the case that they will get sick every time they eat broad beans.
Therefore, not everyone will be poisoned after eating broad beans. Only some people who lack the "G-6-PD enzyme" may experience related symptoms, so there is no need to panic.
It is recommended to do "heel blood screening of newborns" on a daily basis, including the content of "G-6-PD enzyme deficiency", which can be determined in time, reliable prevention, and risk reduction.
Can fresh fungus cause skin cancer?
The reason why fresh fungus cannot be eaten is mainly because fresh fungus contains a photosensitive substance porphyrin. After being ingested by the human body, exposure to sunlight can cause skin itching, inflammation, edema, and in severe cases, skin necrosis and even skin cancer. . When the fresh fungus becomes dry fungus after exposure, most of the porphyrin will be decomposed during the exposure process, and the safety will be higher.
In fact, not only fresh fungus, but also many common foods contain "photosensitive substances", such as celery, which is a famous photosensitive vegetable, but this does not affect our normal consumption in life. Hemoglobin and chlorophyll actually contain porphyrin, which is not unusual.
Based on the current basis, the direct cause of porphyria is that there are too many porphyrins in the skin. Genetic factors cause the normal metabolism of porphyrins in the body, and there is no direct connection with food. You can eat it with confidence.
Therefore, judging from the current scientific information, this statement is not reliable, there are many doubts, and it cannot be believed.
Can unripe tomatoes cause stomach or bowel cancer?
An online article said: Unripe tomatoes contain a lot of alkaloids. If you accidentally eat too much, or eat them with other foods, it is easy to cause poisoning. Eating unripe tomatoes for a long time can cause great damage to the stomach and may induce gastric or intestinal cancer.
Raw tomatoes are indeed not recommended for everyone.
Immature tomatoes contain "alkaloids", also known as tomatine (solanine), which can easily lead to poisoning once ingested in large quantities, and the body is prone to dizziness, vomiting, diarrhea, weakness and other food poisoning. symptom.
For solanine, normal intake of 0.2g-0.4g may induce food poisoning, resulting in vomiting, diarrhea, difficulty breathing, and even organ failure.
It is worth noting that the substance of tomatine will decrease with the continuous ripening of tomatoes, so eating fully ripe tomatoes will not have such problems, and the safety factor will be higher.
It should be emphasized that although the change from cyan to red is a sign of ripeness of tomatoes, some new varieties of tomatoes are still cyan or other colors even when they are ripe, and must be treated differently. And cancer is caused by a combination of factors, and it will not directly cause cancer because of eating a certain food. Everyone must look at it scientifically.
Lentils can't be eaten, otherwise they will cause cancer?
Vegetables such as lentils and green beans do contain some lectins. If they are eaten raw, they will increase the risk of food poisoning, so it is not recommended for everyone to eat them raw. However, there is no risk in eating it completely heated, so you can rest assured.
Therefore, it is too exaggerated to say that lentils cannot be eaten on the Internet. Please treat them rationally.
In addition to these, bean sprouts, ginger and other foods are often taken out by some people as the culprit of poisoning and cancer, but in fact, more of them are "attractive gimmicks", and everyone must pay attention to the distinction.
When eating vegetables, keep these in mind:
- Buy vegetables that are often sold in supermarkets and vegetable markets. It is not recommended to eat vegetables that you have never seen or eaten before to reduce safety risks.
2, do not covet petty cheap, buy spoiled vegetables.
Vegetables are best eaten after being completely heated. Before mixing cold dishes, try to blanch the vegetables to avoid related safety issues.
Eat more vegetables of different types and reduce the intake of a certain vegetable, which not only ingests a variety of nutrients, but also reduces the food caused by excessive intake of a certain food (unsafe food). Risk of poisoning.
In summary
Carcinogenic remarks about vegetables
Everyone has to look at it scientifically
do not blindly believe
