A study has shown that a person’s facial features can vary depending on what the mother ate during pregnancy. [사진=게티이미지뱅크]Everyone has their own unique facial features. These characteristics may have been influenced by the foods mothers ate during pregnancy, with high-protein diets in particular appearing to widen the nose and chin.
According to an international study published in the international academic journal Nature Communications, subtle differences in a person’s appearance, from the shape of the skull to the amount of cartilage in the nose, are determined by genes activated by the nutrition consumed during pregnancy in the womb. . This gene is known as “mTORC1” and its activity becomes more active the more protein you consume during pregnancy.
Dr Meng Zhai’s team at the Department of Physiology and Pharmacology at Kalolinska Institutet in Sweden found that when pregnant rats and fish were fed different diets, mTORC1 signaling changed in utero, giving the offspring specific facial characteristics.
The results showed that a high-protein diet leads to enlarged facial features, such as a more defined chin and thicker nasal cartilage. However, when the mother was given low-protein food, her face became slimmer and her features became sharper.
The researchers explained: “The mTORC1 gene regulates the length of the nose, the width of the nostrils, the shape of the cheeks and the prominence of the chin. As a result, the shape and form of the child’s face can be “fine-tuned.” .’” “Regulating the level of protein in the maternal diet modulates mTORC1 activity, resulting in subtle but distinct changes in the craniofacial shape of the embryo. This leads to a ‘spectrum’ of different facial characteristics.”
The basic appearance of a human face is determined by the genes of the parents, but siblings also have different faces. Even identical twins are not exactly identical. Many scientists have been working for a long time to discover the reason for this subtle difference. The study suggests that a mother’s diet during pregnancy is partly “responsible” for the appearance of her baby.
