Due to the fear of “three highs” (high blood sugar, high blood fat and high blood pressure), more and more people join the ranks of vegetarian diet, but “three highs” control, dizziness, panic, weakness symptoms quietly come. There are more and more vegetarian patients in the hematology clinic, why? Most of them just go to a routine blood test and find out that they are anemic. How can you be anemic? It turns out that meat contains essential iron, which synthesizes the hemoglobin our bodies need, and vitamin B12, another important hematopoietic raw material, the lack of which can lead to nutritional anemia. This includes iron deficiency anemia and megaloblastic anemia. Patients can have symptoms such as weakness, easy tiredness and dizziness. So food meat and vegetarian mix is reasonable, a vegetarian diet is not scientific.
