Exploring the rules Not that long ago, my first thought at mealtimes was to eat at a restaurant. I was eager to try new restaurants. To eat out was also a social activity, allowing me to enhance the relationship with my friends. I often ate out until last month, when I came across a cooking app. There are a variety of recipes in the app to choose from. They are uploaded by users, and offer detailed instructions so that others can follow them step by step. Most of the recipes include photos or videos, which are very useful for beginners. When I picked a popular recipe and gave it a try, I discovered that it was not that difficult to make a simple and tasty dish. In the last few weeks, I’ve thrown myself into home cooking, from boiling noodles in the pot to frying steak in the pan. I hardly eat out any more. Not only is cooking at home cheaper, but I can cook exactly what I want. It‘s healthier too.

It’s not surprising for them to do so. For one thing, with the pace of modern life becoming faster and faster, time is quite precious. In their view, it is unnecessary to take time to cook. For another thing, home-cooked food is simpler in kind and less delicious, especially for those who are particular about food. In my view, our health is closely related to what we eat. The busier we are, the more attention we should pay to food. Therefore, I prefer to cook food at home and go on a balanced diet.

I do not agree with canceling it, as it provides students with variety and flexibility in choosing their meals, which is valuable for meeting different dietary needs and preferences. However, I acknowledge the issues of food waste and nutritional imbalance. To address these concerns, I suggest implementing educational sessions on balanced diets to guide students in making healthier food choices. Additionally, placing clear portion guidance signs can remind students to take only what they can consume. Monitoring and providing feedback on food waste can also raise awareness. These measures can help maintain the benefits of the buffet system while reducing its drawbacks. Thank you for your attention to this matter.
