‘Dual-staple’ eating tends to increase obesity

Eating two or more dishes consisting mainly of carbohydrates at one meal may lead to obesity, according to a recent survey in Osaka Prefecture.

It is not rare in the prefecture, for example, for people to eat okonomiyaki, a savory pancake containing such ingredients as meat and vegetables, and a bowl of rice at one meal. This type of meal is described as a “dual-staple” diet.

People also commonly eat ramen together with stir-fried rice, a meal common around the country.

中略

The manager of the restaurant said: “When the restaurant opened 11 years ago, only a small number of customers ordered rice [together with okonomiyaki], but this has gradually taken root. I fear orders [for rice] may decrease from now on.”
