I’m very much honored to give you a speech on healthy breakfast. Some students in our class often go to school without breakfast while others do have breakfast but not a well-balanced one. Consequently, their health and study efficiency are negatively affected. A healthy and well-balanced breakfast should consist of whole grains, eggs and milk, fruits and vegetables. The grain which contains carbohydrates can provide the energy we need every day. Eggs and milk supply protein and fruits and vegetables are good for healthy digestion. Therefore, I strongly suggest that we should get up early and have a well-balanced breakfast before going to school.
