They find out where pregnancy cravings arise

The pregnancy cravings they are something as common as shrouded in false myths. That if unfulfilled cravings will be a stain on the baby’s skin, that if children inherit cravings that their mothers had during pregnancy… There are all kinds of misconceptions about them. However, the real science behind what causes these cravings for a particular type of food has not been studied much. Yes, there is research, but many open questions remain. Questions that now have new answers thanks to a team of scientists from August Pi i Sunyer Institute for Biomedical Research (IDIBAPS) of Barcelona whose work has just been published in Natural metabolism.

His research focuses on two questions. On the one hand, they detect light switch from pregnancy cravings in the brain. That is to say, they managed to find this brain regions undergo changes during gestation that are related to these eating habits so marked. They did In micebut they believe this can be easily extrapolated to humans, as the neural circuits of these aspects are quite similar.

On the other hand, they detected what changes occur in the offspring mice whose pregnancy cravings have been satisfied. All of this is important, because sometimes these cravings mean poorer nutrition for pregnant women, which can have long-term consequences for their children. If it is detected in which part of the brain these desires arise, you can try to turn them off, in order to avoid these effects. There is still a long way to go to be able to extrapolate it to humans, but its results encourage us.

The origin of pregnancy cravings

The authors of this study measured the brain activity of female mice experiencing food cravings during pregnancy.

Thus, they observed that many changes had taken place in his brain, many of which were associated with the mesolimbic pathway. This means that some sort of rewiring has taken place in the reward systems.
