Healthy Eating Habits
It is said that, “Food is the first necessity of people.” Healthy eating habits are very important to us. We can have some bread, milk or eggs for breakfast, but do not eat heavy food. For lunch it is OK to have rice or noodles, and it is necessary to have some meat and vegetables. Having a cup of yogurt at lunch time is also good for our bodies. We should choose light food for supper and we shouldn't eat too much. And we can have some healthy food that we like. If we do like this, we will be in good health.
