Could Japanese Americans be more at risk for anorexia?

It may not seem like much of a shock, but the typical Japanese girl is almost held accountable to be a tiny little stick. Japanese girls are known for being thinner, so if one of them just so happens to be struggling with their weight, there is more pressure for them to change their body. According to the South Carolina Department of Mental Health, anorexia rates are continuing to go up in Japan. It seems logical that anorexia would especially be a concern to Japanese girls who travel to America. They are used to their cuisine back at home, and after eating American food, they begin to gain weight. According to a video found on youtube, there is a lady who went through this exact situation. Thankfully, she did not choose anorexia to fix her problems because she truly enjoyed eating. Luckily she could solve her problem by traditionally cooking her food and incorporating this western diet into her original cuisine. What about the girls who feel as though diets do not work, so they choose to starve themselves? It seems as though it is a hopeless situation, and I truly would like to help those who struggle with it. There is only so much we can do in such a thin-focused society.
