Say No to Junk Food
Dear students,
Nowadays, we can buy junk food easily. Many of us love snacks like chips and soda because they taste good. However, these foods can be bad for our health. Eating too much junk food may not only make us put on weight, but also cause health problems.
To keep away from junk food, we should focus on how to keep a healthy life. First, eat three meals a day on time. Second, eat more fruit and vegetables. What's more, do more activities outside and drink a lot of water instead.
Together, we can build better eating habits and say no to junk food!
