Horse meat is Pagan food?

Reading through Archaeology.com, one article stood out to me.
"Why Brits stopped eating horese meat"
It was interesting because the article itself was very short with few facts saying that eating equine meat had fallen out of practices during th late 8th century. Poole, a doctorate candidate for Nottingham University, suggested that it was because the practice was drive out by Christianity and that horse meat was associated with Pagan practices, which would have been supressed at the time.
Horse is related to Pagan gods and known to have eaten the meat for religious purposes.
