Popular Food

I have never heard that blueberries is popular in Korea. I think reason of this popularity is to appeal many good effect eating it on TV and other mas-medias. It also says in Japan. For example, Kanten, Natto, and Apples. These were said to good for diet on mas-medias. Thus people are influenced by mas-medias. Not always it is good things. Many people believe mas-medias too strong, and they don't think themselves. It is too bad.
