What children eat does make a difference, especially in school, reports a study published last year in the Journal of School Health, a journal published on behalf of the American School Health Association.
To establish a link between diet and academic performance, University of Alberta (Canada) researchers evaluated the lifestyle and performance of some 5,000 children. Students who ate an adequate amount of fruit, vegetables, protein and fiber, with less calorie intake from fat, did better on their literacy tests than those eating foods high in salt and saturated fat.
While a healthy diet is generally assumed to be important for good school performance, there has actually been little research on this topic. To date, most research on diet and school performance has focused on the importance of eating breakfast, as well as the ill effects of hunger and malnutrition.
The study looked at 4,589 fifth-graders participating in the Children's Lifestyle and School-performance Study, 875 (19.1 percent) of whom had failed an elementary literacy assessment.
The better a student's eating the less likely he or she was to have failed the test, the researchers found, even after they adjusted the data for the effects of parental income and education, school, and sex.
This study demonstrates the importance of overall diet quality to academic performance and gives emphasis to the importance of children's nutrition not only at breakfast but throughout the day.
So what can you do to ensure your children are performing to their optimal potential at school?
Start them off with a nutritious breakfast and pack them a health-promoting lunch consisting of whole grains, fresh fruit and vegetables and protein to ensure they obtain the daily recommended intake of vitamins and minerals.
Children need the right foods to keep them going through the day so they can carry out their tasks of learning, playing and growing. Healthy food will give them enough energy to last the school day and will also provide the building blocks for a healthy adult.
The best kind of energy is the kind that is consistent, avoiding the highs and lows provided by sugar. To get this kind of good stuff in the supermarket, you'll need to arm yourself against the charms of many food manufacturers and the irresistible appeal of clever packaging. "Low Fat" does not mean low sugar, and "natural" does not always denote wholesome ingredients.
Two simple rules to remember when grocery shopping are: The fewer ingredients on the label the better; and if you can't pronounce it, you probably shouldn't be eating it. You can never go wrong if you choose "whole foods." Whole foods are foods that are unprocessed and unrefined, or processed and refined as little as possible before being consumed. They typically do not contain added ingredients, such as sugar, salt, or additional fat.
As parents, we face the usual lunchbox dilemma: we want to pack a nutritious healthy lunch for our kids, but we are typically feeling rushed for time every morning. Lunches don't have to be complicated; with a little planning, simple, nutritious meals can be put together in minutes.
