Good Breakfast Equals Good Grades It is back－to－school time in much of the world.Calm，easy mornings are replaced① with busy，hurried ones.Children wake up early and get ready for school.Many parents are also getting ready for work，helping their children and preparing food for lunches.But，don't forget about breakfast! A Welsh study These are the findings of a study in 2015 in Wales.Researchers looked at 5,000 teenagers aged 9～11 from more than 100 primary schools in the UK.They looked at what the students ate for breakfast and then their grades 6 to 18 months later. They found that the students who ate a healthy breakfast were twice as likely to perform above average in educational activities.The researchers also found that unhealthy breakfasts—such as potato chips or a donut② did not appear helpful to educational performance. What is a healthy breakfast? Health experts suggest that the best breakfast is a mix of complex carbohydrates③，protein④ and fat.This gives your body the energy it needs to think clearly and to remember what it learns. They found that when it comes to giving the brain what it needs to work at its highest level—not all breakfasts are created equally. Health experts suggest not eating too much for breakfast.This can also make a person feel tired and unable to think clearly.They say eating between 350 and 500 calories in the morning is a good amount of ⑤ energy to start the day. Breakfast is not just good for students. A good breakfast is not just helpful for school－aged children.We all may gain a lot from eating something healthy in the morning. A study from researchers at the University of Toronto in Canada found that a breakfast rich in protein and complex carbohydrates increased performance on short－term and long－term memory.Carbohydrates and protein are especially important because they have a major effect on long－term memory.
