1. Water Bamboo
Many people believe that the black spots on water bamboo mean it has gone bad. In fact, these black spots are a type of fungus, such as Ustilago esculenta, which helps slow down the aging of bones. However, women around their menstrual period, patients with weakness, kidney failure, or urinary tract stones should avoid eating water bamboo.
2. Spinach
Vegetable lovers who want to supplement calcium should not miss spinach. A small bowl of spinach can provide 25% of the daily calcium requirement. Additionally, spinach contains fiber, iron, and vitamin A, which are beneficial for health.
However, note that spinach contains oxalic acid and phytic acid. It needs to be blanched before cooking, otherwise, these acids will bind with trace elements like calcium, iron, and zinc to form compounds that cannot be absorbed, affecting the absorption of these minerals.
3. Cabbage
Although many vegetables contain calcium, they also contain oxalic acid, which reduces calcium absorption. For example, water bamboo, bamboo shoots, spinach, water spinach, amaranth, and celery. Therefore, it's best to blanch these vegetables in boiling water before cooking to remove most of the oxalic acid.
