From Daniel 1:12-15, “‘Test your servants for 10 days: Give us nothing but vegetables to eat and water to drink. Then compare our appearance with that of the young men who eat the royal food, and treat your servants in accordance with what you see.’ So he agreed to this and tested them for 10 days. At the end of the 10 days, they looked healthier and better nourished than any of the young men who ate the royal food.”
It seems obvious that food that nourishes our body serves a purpose similar to medicine’s purpose. Our math and engineering friends are therefore logically asking, “isn’t medicine food?”
