the fruits and veggies you eat have been severed from the vine. they're as dead as any meat product. this theory would only apply to fruit/veggies you talked to while they were still on the vine.
im sure if you talked nice to a chicken before slaughtering it you'd get better quality meats products.
The wrath of God is being revealed from heaven against all the godlessness and wickedness of men who suppress the truth by their wickedness, since what may be known about God is plain to them, because God has made it plain to them. For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse. (Romans 1:18-20)
