As we all know, vegetables are an integral part of people's daily diet. Not only are they rich in nutrients such as calcium, carotene and vitamin C, but they also have the effect of preventing many diseases. However, in recent years, some negative information about vegetables has begun to surface, the most representative of which is water spinach.
1. Water spinach
According to research, water spinach is rich in dietary fiber, vitamin C, potassium and other nutrients, and has a variety of benefits for the human body, such as lowering cholesterol, preventing constipation, and protecting the liver.
However, in recent years, a saying has begun to circulate on some ** and social platforms: water spinach is the "king of all poisons", and excessive heavy metals also cause cancer, which makes many people panic about water spinach.
2. Is water spinach really the "king of all poisons"?Heavy metals exceed the standardCarcinogenic
1. We need to make it clear that the heavy metal content in water spinach is indeed high
This is mainly because water spinach grows near water or in paddy fields and easily absorbs heavy metals from soil and water. However, this does not mean that water spinach is the "king of all poisons", and it does not mean that water spinach can cause cancer.
2. The heavy metal content in water spinach does not necessarily exceedmark
The study found that the heavy metal content in water spinach was closely related to the growth environment. If water spinach grows in areas with heavy metal pollution, then its heavy metal content may exceed the limit.
However, if water spinach grows in an area with low heavy metal content, then its heavy metal content may not exceed the limit.
3. The heavy metal content in water spinach will also be affectedfactors
Such as soil quality, water quality, fertilization, etc. If water spinach grows in a good environment, it may have a low heavy metal content.
Therefore, when we buy water spinach, we can choose water spinach from areas with low heavy metal content, or choose water spinach grown with soilless cultivation technology to avoid heavy metal pollution.
3. There is no scientific basis for the claim that water spinach causes cancer
Studies have found that water spinach contains some natural substances, such as mushroom toxins, glucosinolated glucosinolates, etc., which may have certain anti-cancer effects.
In addition, water spinach is also rich in nutrients such as dietary fiber and vitamin C, which also help prevent cancer.
However, it is important to note that substances such as muscarcotoxins and glucosinolates in water spinach may also cause certain harm to human health. Therefore, when we consume water spinach, we should eat it in moderation and avoid excessive consumption.
