Eating raw and cold food will not make the fetus grow birthmarks, the two are not related.
Fetal birthmarks are mostly related to pigmentation, melanocyte retention, vascular malformations, etc. If pregnant women consume too much food with pigmentation during pregnancy, or are affected by family genetics, environmental pollution, fetal vascular malformations, etc., the fetus may grow birthmarks.
The consumption of raw and cold food by pregnant women may cause irritation to the gastrointestinal tract, nausea, abdominal pain, diarrhea and other discomforts, affecting the normal intake of food, which may affect the development of the fetus, but will not cause the fetus to grow a birthmark.
Therefore, there is no relationship between the consumption of raw and cold food by pregnant women and the growth of birthmarks in the fetus, but for the growth and development of the fetus, it is not recommended for pregnant women to eat raw and cold food.
