The recent trend of "Lunch Activities" or "Ran-Katsu" in Japanese society involves people making conscious, deliberate food choices, but it is creating a divide. As healthier lunch choices are often expensive, this trend highlights economic disparity within society. However, experts suggest that the key is in choosing balanced meals, regardless of budget, thereby promoting overall health and wellbeing.

In Japan, the trend of Ran-Katsu symbolizes a deeper exploration of food culture and health consciousness. It impacts not only nutrition levels but also the ongoing discourse on societal and economic equality. With a high emphasis on health, diet, and longevity, Japanese society is seriously considering the implications of this trend on the wider population.

This trend is similar to the "healthy eating" and "organic food" movements in the US and EU, which can also be pricy, leading to discussions around food access and income inequality. The US and EU have initiatives to promote healthy eating across all socioeconomic sectors and confront food deserts.
