According to recent research, 7% of Americans (roughly the population of Pennsylvania!!) believe that chocolate milk comes from…you ready for this? BROWN COWS!!! As recent as the early 90’s 1 in 5 didn’t know hamburgers were made of beef. A bunch of 4th, 5th and 6th graders in California were asked where cheese came from..they didn’t know it was milk/dairy. They also didn’t know onions & lettuce were plants!!
