Chewing prepares your gut for digestion iirc, we didn't evolve to eat blended foods so the gut isn't ready for soup, so chewing is probably beneficial?
Yeah! Whatever it takes to get that ice cream in my mouth. Bite, lick, slurp, pick it off my shirt with my fingers, suck the remaining ice cream out of my shirt, whatever I need to do. Mostly bite it though. Little bit at a time.
Proper ice cream is 20 degrees F. It's too cold to just schlorp it off with your lips. If you can, it's melted and you've missed important texture. That's why I eat my ice cream with a knife.
Lol, do your partners\parents\siblings complain that you consume too much if you're sharing something? It's not our fault they consume things so slowly.
