Chewing food aplenty warms it up, its gotta be a certain temp to enter your stomach...its why folk are sick when drinking ( it aint even in the stomach cause youre gannet central)....if youre eating food that doesnt contain a days tick list of nutrients and youre chewing...the chewing will mean the bodies waiting for them nutrients..when it doesnt get em cause youre processed out of your bollox...it sends the acid upstairs to breakdown what it thinks is a blockage cause youve been chewing and its been short changed.
