Experts: hollow cabbage can be safely eaten

Zhu Yi, associate professor of food science and nutritional engineering at China Agricultural University. Zhu Yi said the production of agricultural products depends on three major factors, namely air, soil and water quality. Whether it's airborne or other vegetables, there are strict indicator requirements for these three elements. If the environment where the vegetables grow has air pollution, industrial waste or industrial sewage irrigation, the pollutants will be adsorbed by the vegetables, while the hollow cabbage has no other special ability. So if the nearby environment is seriously polluted by heavy metals, no matter what vegetables are planted, the heavy metals will exceed the standard, and the aquatic hollow cabbages will also exceed the standard. "Such rumors are pure nonsense, and the hollow cabbage can be eaten without fear."
