After the economic reforms that initiated economic growth, Hanoi's appearance has also changed significantly, especially in recent years. Infrastructure is constantly being upgraded, with new roads and an improved public transportation system. Hanoi has allowed many fast-food chains into the city, such as Jollibee, Lotteria, Pizza Hut, KFC, and others. Locals in Hanoi perceive the ability to purchase "fast-food" as an indication of luxury and permanent fixtures. Similarly, city officials are motivated by food safety concerns and their aspirations for a "modern" city to replace the 67 traditional food markets with 1,000 supermarkets by 2025. This is likely to increase consumption of less nutritious foods, as traditional markets are key for consumption of fresh rather than processed foods.
