Numerous studies have validated the claim that healthy eating boosts academic performance. Students who do not eat breakfast tend to have difficulty in memorizing and paying attention in class. A recent study in Canada followed 6000 students in Toronto schools and showed positive results. 70% said having breakfast boosted their energy levels while 61% exceeded provincial reading standards. Countless studies have also been conducted in the US which also further help in pointing that a well-balanced nutritional diet boosts academic performance and overall health of students in high school.
Mixed-Grain Diet and Cognitive Functioning
Mixed-grain diet has found out to improve cognitive performance in students. A study conducted in 2012 revealed less mental fatigue and higher level of protein in the brain, by eating mixed grains, indicating a healthy brain. Sugary sodas and a junky diet cause childhood obesity which decreases cognitive functioning.
Poor Nutrition and Lower Test Performance
Poor nutrition produces a stress hormone cortisol in excess. This hormone affects the brain and impairs learning, memorizing, paying attention and controlling impulse. Students who eat unhygienic, highly processed poor food have been found to score less on tests and exhibit behavior problems compared to well-nourished students.
A study conducted in 2011 found that drinking milk is associated with better performance. Sweetened beverages tend to impair alertness and understanding. In the study, students who ate regular breakfast scored higher on math tests compared to those who skip on their breakfasts. Other factors which help boost performance on tests include physical activity and eating healthy food.
Regular Breakfast Improves Memory
Regular breakfast no wonder provides with the required nutrition to function properly through the day. One study conducted by Gregory Phillips of college students showed that those who ate breakfast regularly passed their biology exam. It is also recommended to have a snack in between breakfast and lunch. Having a mid morning snack actually improves memory. Blueberries and yoghurt have been linked to improve memory in some studies. A hardboiled egg is also good to have in breakfast as it contains choline, a nutrient which has been found to improve memory in animal studies.
Proper Nutrition Helps Stay Alert
Inadequate nutrition, calories and junk food makes students feel lethargic and participate less in school activities. Eating proper, healthy and hygienic food prevents them from falling ill and helps them stay alert in school and focus on lectures and understand better. It helps the student to be more positive and show enthusiasm for a better learning.
Food Quality and Academic Performance
Spanish studies have found out that the quality of food students has also affected their performance academically. The study showed a direct relationship between food quality and academic performance. As food quality increased, students academic performance also increased. Certain mental processes such as comprehension, memory and concentrationwere affected more than others when food quality differed.
Physical Activity is also Important
Countless studies validate that eating healthy improves functioning of the brain. It helps the mental processes in understanding, interpreting, focusing and keeping alert in school thus, improving academic performance. Proper nutrition is like food to the brain and a balanced diet keeps students both active and prevents them from feeling tired.
Apart from maintaining a healthy diet, daily physical activities are necessary. Eating right is one part of the game, but if students take part in extracurricular activities and stay physically active and fit, studies have found them to perform better in classes. It improves attention and concentration in class. The oxygen which reaches the brain helps with better functioning and also prevents obesity in students.
