The version circulating on the Internet believes that sunflowers can easily absorb heavy metals such as lead, cadmium, and nickel in the soil, and eating sunflower seeds will consume a large amount of choline, causing the liver to accumulate a large amount of fat and affecting the function of liver cells. Therefore, sunflower seeds are carcinogens.

Another medical expert, Zhu Yi, believes that sunflowers are not the easiest to absorb heavy metals, and choline has nothing to do with causing cancer.

However, regardless of whether sunflower seeds are carcinogens or not, you should always pay attention to controlling your intake when eating sunflower seeds. Because the salt content of melon seeds is too high, it can easily cause high blood pressure, and high blood pressure can easily cause other diseases. Moreover, if you eat melon seeds for a long time, the melon seed shells will take away a lot of people's saliva. If there is a lack of saliva, it will cause threats and harm to people's life and health.
