Do you skip breakfast? Millions of people do, and if you are one of them, you are putting your ability to think and learn at risk. Skipping breakfast can cause you to be hungry, tired, or grumpy by the middle of the morning. Why is that? First, when you wake up, you have not eaten for about eight hours. Your body’s fuel, called glucose, is low. Eating breakfast raises the level of glucose in your brain. Your brain requires a constant flow of glucose to do mental work.
So eating breakfast will give you a mental edge at school. What if you don’t have enough time for breakfast or if you are not hungry when you wake up? Having something for breakfast is better than nothing. Drink some milk or juice. Then catch a nutritious snack later on in the morning. Yoghurt, dry cereal, cheeses, or fruit are good choices. What if you don’t like breakfast foods? Then eat healthy foods you do like. Even cold pizza or a fruit smoothie can power your morning. Any way you look at it, there’s no reason to skip this essential meal.
