1, who shouldn't eat broad beans?
1, silkworm disease patients
Because of gene defects in the body, patients with silkworm bean disease will have allergic reactions to broad beans when they come into contact with nestin glycosides in broad beans, such as pallor, nausea, vomiting and even coma, accompanied by abnormal liver function.
2. People with a family history of silkworm diseases
If it is a patient with silkworm bean disease, but it is not induced, it is difficult to find out the disease. Silkworm bean disease is a recessive genetic disease of sex chromosome, which is likely to be passed on to the next generation. Therefore, people with a family history of bean diseases should be careful to eat broad beans.
3. People with bloating
Broad beans contain a lot of carbohydrates, especially starch. Carbohydrates that the body can't fully digest will produce gas under the action of gas-producing bacteria in the intestine, which is prone to flatulence in the abdomen, and some people even have diarrhea.
4. Obese people
Broad beans are high in calories, especially starch, which is decomposed into glucose in the body. Obese people who eat more broad beans will cause excess calories in the body, which will be converted into fat and accumulate in the body, which will eventually lead to obesity.
5, people with bad stomach.
Broad beans are not easy to digest, especially broad bean skin, which contains a lot of cellulose. People with a bad stomach are also not suitable for eating broad beans, which will increase the digestive burden of the stomach and cause physical discomfort.
2. What happens when you eat too many broad beans?
(1) causes diarrhea and abdominal distension.
Broad beans are sluggish and should not be eaten raw. Raw broad beans should be soaked or blanched several times before cooking. Don't eat more to prevent abdominal distension from hurting the spleen and stomach, leading to abdominal distension and diarrhea.
(2) Causing constipation
Eating too much broad beans may also induce constipation, because broad beans are also high-calorie foods. It is easier to buy fried broad beans because they already contain a lot of starch and fried broad beans contain less oil, so eating too much can easily lead to constipation.
(3) cause obesity
If you buy fried broad beans, it is more likely to lead to obesity, because broad beans contain a lot of starch, and fried ones also contain some oil. Stir-fried broad beans taste delicious with salt, and are easy to overeat. Without knowing it, they eat a big bag and get fat easily. This kind of snack is taboo for people who want to lose weight. It is easy for people to overeat and get fat unconsciously.
(4) cause anemia
Acute hemolytic anemia is caused by the dissolution and destruction of red blood cells in blood vessels in a short time after eating broad beans, commonly known as broad bean yellow. Why do broad beans dissolve and destroy red blood cells?
We know that red blood cells are one of the important components of blood. In its life span of 1.20 days, they have to travel back and forth to the large and small blood vessels 5 165438+ ten thousand times to deliver oxygen to the tissues of the whole body. This effect depends on its elastic and flexible envelope, which makes it extremely plastic. It can not only pass through large blood vessels smoothly, but also squeeze through capillaries with twice the diameter again and again without being torn.
Red cell membrane, like all living things, relies on energy generated by metabolism to maintain its function, and the metabolic process requires a series of enzymes (equivalent to catalysts needed in chemical reactions). The defect of any enzyme will affect the normal metabolism and energy production, and make the erythrocyte membrane lose its elasticity and flexibility. If the substance similar to oxidant in blood increases, it will aggravate the defect of enzyme and make the erythrocyte membrane stiff and easy to be destroyed.
(5) cause allergies
Broad bean is a kind of vegetable with high nutritional value, but because broad bean, especially fresh broad bean, contains allergic factors, some people will be allergic after eating broad bean, and even after smelling the pollen of broad bean. Mainly manifested in the destruction of a large number of red blood cells, yellowing of the skin and destruction of the eyeball. This is due to the lack of an enzyme in the body of the body fairy, which belongs to genetic defect. People who are allergic to broad beans can't eat any more.
(6) causing silkworm diseases
After a few people eat broad beans, it will cause bean diseases, and children eat broad beans for the first time. Nestin glycoside is a toxic substance, which mainly exists in broad bean and broad bean pollen, especially in fresh young bean. After being ingested, it competes with glucose 6- phosphate in vivo, which can cause "silkworm disease". Often appear chills, fever, nausea, vomiting, abdominal pain, low back pain and other symptoms. Anyone with allergic history of silkworm bean disease and suffering from hemorrhoid bleeding, uremia and colitis should not eat broad beans.
