I am always checked by my daughter who majors in a nutritional science in university when we eat together because I love to drink pop soda.
The Bible introduces us the Real Food and Real Drink which we Christians should eat and drink.
We read in, John 6:54-55;
“Whoever eats My Flesh and drinks My Blood has eternal life, and I will raise him up at the last day. For My Flesh is real food and My Blood is real drink.”
