I grew up in Japan in 60’s. I have never heard of “cereals” until I moved to Australia in 1984. I thought that’s interesting. People eat sweet substances with milk and a glass of orange juice in the morning. I tried for a while but got so hungry and irritable within a couple of hours. That’s my memory of cereals. This is the interesting article about ingredients of Cheerios. Are you going to eat a bowl of Cheerios tomorrow morning???
