Overall, I think I have unhealthy eating habits. As for the things that I am doing right, I eat different categories of food, especially fruit and vegetables. Moreover, I rarely consume sweet food and processed food. However, I do have some bad eating habits. For instance, I sometimes find myself skipping breakfast or eating too much, which may result in stomach problems. In addition, I eat too much hot and spicy food.
