Pros and Cons of fast-food culture

Fast-food culture has been widely accepted in Japan. The more society in Japan is westernized, the more fast-food is also accepted. Now I'll talk about Pros and Cons of fast-food culture. First, pros of fast-food culture is efficiency. Fast-food contributes to reduce time to take. For example, business people work hard as a bee. They don't have enough leeway to enjoy food. McDonald humbugger is a typical case. We need just 5 minutes to eat. As is often the case, fast-food is relatively high calory. Therefore, we can keep energy through eating fast-food. Time and calory efficiency would be pros.
To the contrary, long term effect on health is cons. One American film, "Super size me", took up fast-food. The leading character keeps eating fast-food for a month. The result shows us that only eating fast-food aggravates our health condition. It's very ridiculous.
In my opinion, I love fast-food even if a lot of people criticize it because fast-food is grease and leads to obesity. Humbugger of Burgerking, French fry of McDonald are the best combination.
