2. 范文示例
My Healthy Eating Habit
Eating well is the key to good health. I have kept a healthy eating habit for years, and it makes me feel energetic every day.
For breakfast, I usually have a glass of milk, a boiled egg and a piece of whole-wheat bread. Milk and eggs give me protein, and whole-wheat bread provides energy for my morning study. For lunch, I always eat rice, some fresh vegetables like tomatoes and spinach, and a little meat or fish. I never eat fast food for lunch because it has too much oil and salt. For dinner, I have noodles or porridge with vegetables. I don’t eat too much at dinner because eating too full at night is bad for digestion.
My favorite food is fish and apples. Fish is tasty and rich in protein, which helps me grow strong. Apples are sweet and full of vitamins, and they are good for my skin. I don’t like chocolate or potato chips because they have too much sugar and fat.
A healthy diet is not only delicious but also good for our body. I hope everyone can develop a good eating habit and eat well to keep fit!
