"abstemious diet for a month or two would convince many sufferers that the path of self-denial is the path to health. MH 235.2"
"Prove thy servants, I beseech thee, ten days; and let them give us pulse to eat, and water to drink."
Both passages advocate for a simple, abstemious diet as a path to improved health. The Daniel passage provides a specific example, while the EGW passage suggests a general application of the principle.
