Avacado oil

Is it ok to use olive oil? Do you use it for health purposes or will it affect the taste and texture? I’m a big fan of spelt and would love to try this recipe...I’ve been looking out for a good spelt challah recipe and this sounds great but I need to know about the oil first. I’ve never used avocado oil in the past and would love to stick to my olive oil,which is more familiar to me
