Four kinds of vegetables should not be eaten raw. What should you pay attention to when eating vegetables in summer?

　　As the weather gets warmer day by day, people's tastes also change day by day. Change from liking hot food in winter to eating cold food in summer.

　　It is true that the vitamins of vegetables are not destroyed when eaten raw, but it is worth mentioning that not all vegetables are suitable for eating raw. Because eating some vegetables raw will waste nutrients, some are not easy to digest, and some may even cause food poisoning. We interviewed relevant experts to tell you that the following four types of vegetables should not be eaten raw.

　　Blanch spinach, water spinach, etc. and then serve them cold

　　Spinach, water spinach, bamboo shoots, wild rice and other vegetables that contain a lot of oxalic acid are best blanched to remove most of the oxalic acid before being served cold. Because oxalic acid combines with calcium in the intestines to form calcium oxalate, which is difficult to absorb, interfering with the body's absorption of calcium.

　　Lentils and other beans are prone to poisoning when eaten raw

　　Most beans, such as lentils, kidney beans, and sword beans, are not suitable for eating raw. This is because the saponins in the lentil skin and the hemagglutinin in the beans are both highly irritating to the gastrointestinal tract. Saponin, also known as saponin, is a poisonous protein in itself. The two ends of beans, pod silk and old lentils have the most toxins.

　　When cooking beans, they need to be cooked thoroughly to destroy their toxins. Even if they are served cold, they must be cooked in boiling water for at least 10 minutes.

　　Finally, a reminder that cold food eaten raw can be neutralized with onions, ginger, garlic and other seasonings. For example, when mixing bitter melon and cucumber, add some minced garlic. ； Or drink a bowl of brown sugar ginger water after eating, which can weaken the coldness.
