Green beans are also a kind of vegetable with high nutritional value, which many children like to eat. If the green beans are not cooked, the saponin hemagglutinin in the green beans will not be completely removed, which will stimulate the digestive tract mucosa of children and lead to diarrhea and stomachache, which is easy to cause green beans poisoning.

2. Eat tomatoes before meals and eat green tomatoes.

Tomatoes should be eaten after meals. In this way, the acidity can be greatly reduced by mixing gastric acid with food, and the symptoms such as abdominal pain and stomach discomfort caused by the increase of pressure in the stomach can be avoided. Don't give green tomatoes to children, because green tomatoes contain solanine, which makes them prone to nausea and vomiting and gastrointestinal symptoms.

3. Eat fresh daylily.

Because there is colchicine in fresh day lily, it will be oxidized into colchicine when it enters the human body. After eating it, it is prone to nausea, vomiting and numbness of hands and feet. In fact, after the day lily is dried, these toxic colchicines will disappear, which is more conducive to health.

4. Eat uncooked bean sprouts.

Bean sprouts are tender, delicious and nutritious, but they must be fried when eaten. Otherwise, nausea, vomiting, diarrhea, dizziness and other uncomfortable reactions will occur after eating.

5. Eat too much spinach.

Many parents will say that eating more spinach can supplement iron, but in fact, spinach contains a lot of oxalic acid and should not be eaten too much for children. Oxalic acid will react with calcium and zinc to form calcium oxalate and zinc oxalate in human body, which is not easy to be absorbed and excreted, affecting the absorption of calcium and zinc in intestine, easily causing calcium deficiency and zinc deficiency in children, leading to bone and tooth dysplasia, and also affecting intellectual development.

6. Drink too much carrot juice.

Although carotene is very nutritious for children, we should also pay attention to proper consumption. Children who drink carrot juice too much may cause carrot blood disease, make the skin of face and hands turn orange, and appear loss of appetite, unstable mental state, fidgety, even restless sleep, accompanied by night terrors, crying, talking in sleep and other manifestations. The best way to eat carrots is: after steaming, cut into small pieces or strips for the baby to eat by himself. This will not only absorb more nutrients, but also exercise the baby's grasping ability.

7. Give children bitter gourd that has not been boiled in boiling water.

Oxalic acid in bitter gourd will hinder the absorption of calcium in food. Therefore, before eating, the bitter gourd should be blanched in boiling water to remove oxalic acid. Children who need to supplement a lot of calcium should not eat too much bitter gourd.

8. The leek is stored for too long after it is cooked.

Leek is best cooked and eaten now, not for a long time. If it is stored for too long, a large amount of nitrate will be converted into nitrite, causing toxic reactions. In addition, children with indigestion can't eat leeks.

9. Cook the green leafy vegetables.

Green leafy vegetables should not be stewed for a long time when cooking. Because the nitrate in green leafy vegetables will turn into nitrite, it is easy to make children suffer from food poisoning. There are phytic acid, tannic acid, etc. in vegetables, which will be dissolved in water during cooking. These "bad" substances are not conducive to the absorption of minerals such as iron and calcium.

10, edible amaranth.

Amaranth contains relatively high nitrate, and there are many bacteria in the baby's mouth, such as Pseudomonas aeruginosa, Proteus, Bacillus and so on. These bacteria are more in the mouth of babies under 1 year-old, and it is easy to convert nitrate into nitrite, so the baby will be at risk of nitrite poisoning and get cyanosis.
