It was told to me by my nutritionist that I should never eat and drink at the same time. I was told that I should wait 30 min after eating to consume liquids. Since my surgery, I don't think I've actually followed through with that suggestion once. Although, I do wonder often how big of a mistake I'm making. Does anyone know why this is a suggestion? And how detrimental it is to my body and/or health by not doing so?? If detrimental at all of course.
