Ever since the rainy season ended, it has been very hot here in Japan - even hotter than usual. Not surprisingly some food items sell well when the weather is sweltering. Sports drinks, ice cream and beer come to mind, but other items as well.
One item which comes as a bit of a surprise to me is milk. I love milk and it is cold, but it is also thick. If I am really hot, I usually want to drink something a bit more watery, like a sports drink or water itself, but sales of milk are usually helped quite a bit by hot summer temperatures. Maybe people are smarter than I give them credit for and choose healthy milk over sugary drinks.
