That's strange, because according to other sources, the secret of why the Huns' and Tatars' strength and physiques were superior to Romans and other "civilized" peoples was attributed to raw meat, and it also helped them avoid being spotted by their enemies, because they didn't need to build campfires. To use some of the greatest eaters and promoters of raw meat in Neolithic times as reason to not eat raw meat is bizarre.
All the peoples of the steppes and Siberia and surrounding areas were reportedly great consumers of raw meat and/or fish: Huns (who probably included other steppes and nearby peoples in addition to Huns in their confederations, such as Turkic, Yeniseian, Tungusic, Ugric, Iranic, and Mongolic), Tatars (another name later loosely applied to many steppes peoples, from which the name steak tartare comes from), Mongols, Celts, Scythians, Turks, Avars, Kets, Nenets, Tuvans, etc.
Attila the Hun and Steak Tartar
www.schonwalder.org/Menu_Special_Steak_Tartar.htm"Attila's men ate raw lean meat cuts which being placed under their saddles were tenderized for as long as a day's ride." ....
"People feared the Tartars but attributed their strength to the energy source of raw meat and spices." Wanting to be much like the feared Huns, people in western Europe first secretly but soon openly prepared food the way they had seen the nomads do it. They tenderized meat and added spices.
"... and that's where the steak tartar as we know it today originated!"
"They are short in stature, quick in bodily movement, alert horsemen, broad shouldered, ready in the use of bow and arrow, and have firm-set necks which are ever erect in pride." Jordanes.

The Hun
"In the tradition of Mongol warriors, the Hun ate mare's milk, blood, and raw meat if necessary."
www.hyperhistory.net/apwh/bios/b3atilla_p1dz.htmOthers claim the Huns kept meat under their saddles to keep it warm, rather than necessarily tenderize it:
"...he tells us that the Huns ate raw meat which they warmed a little by carrying it between their saddles and their horses' backs." --The Huns by E. A. Thompson, Peter Heather
