your Grandparents are shaking there heads in disgust.
Soy milk? Are you kidding?
My grandparents lived to be 92 and 99. Ate the beef and chickens they raised. Sunday meals consisted of several fried chickens, fried okra, fried squash, real mashed potatoes with plenty of butter, chocolate and pecan pie, and a large pitcher of milk and sweet tea.
When my sweet grandmother died at 99, 3 months shy of 100, the doctors came out and said "If only she had drank soy milk all of her life, she might have made it to 100"
NOT!
