1. Raw green beans.
Green beans are common vegetables, because the skin is thick and not suitable for frying, but the green beans that are not fried are poisonous and not suitable for eating. Therefore, when cooking green beans, you can scald them with hot water first, and then fry them when they are cooked in July and August, which is more secure to eat.
2. Green tomatoes.
If you see a blue tomato in the supermarket, don't doubt whether it is a new variety, it is just immature. Unfamiliar people will embarrass you, and unfamiliar tomatoes will poison you, so it is most reliable to buy tomatoes honestly and red ones.
3. Deteriorated ginger.
Ginger is an essential seasoning at home, so almost every household will eat some. However, with the increase of temperature, some ginger will soften and deteriorate, and the appearance will not change much after a long time. But if eaten at this time, it will not only cause diarrhea, but also cause cancer.
It can be seen that although vegetables have many benefits, they still need to be carefully selected in the process of eating, and the premise of avoiding these toxic vegetables is always safety.
