Academic achievement was recorded from the final results of their school exams. In conclusion, there was no significant difference between nutritional status. Cyclical Relationship Between Poor Nutrition and Educational Outcomes. Because academic performance influences future health, it's an important public .
The surveys looked to identify fat intake with cognitive and psychosocial functioning. The results of the surveys found that the consumption of Polyunsaturated Fatty Acids PUFAs was associated with a decreased academic performance, while increasing cholesterol showed an increase in poor performance.
The researchers also stated that their report had limitations; the cross-sectionalism of the report limited them from asserting causality, the possibility of inaccurate information supplied by the mothers in an effort to appease social desirability, as well as the limitation of having created anything but rough data in only a 24 hour diet recall period [ 6 ].
As Wood [ 3 ] found through a 21 week study that followed iron levels of volunteers with borderline anemia, low iron levels in children has a direct effect on the ability to pay attention to information. This information was used for both children with iron deficiency without anemia and children with iron deficiency with anemia. They differentiated between the two groups using a routine screening for hemoglobin levels, which indicates anemia when levels are below the amount calculated for each age group.
This equates to approximately 1. The limitations of the study are similar to those of Zhang et al. Secondly, smaller portions of available statistics for children with anemia may also have prevented the study from finding a larger association between anemia and cognitive scores.
The effects of poor diet, as well as deficiencies in dietary intake, can be seen through the above studies. Weight, height, and Body Mass Index BMI were assessed in both kindergarten and 3rd grade, when the two studies took place. Overall, there were 11, students for whom full data was available for both kindergarten and 3rd grade. Food insufficiency was measured by the quality and quantity of food supply within the previous 12 months. In order to measure academic performance, researchers administered direct assessments of math and reading skills individually and were calculated using Item Response Theory IRT.
The results of the longitudinal study showed that children from persistently food insufficient homes showed a smaller increase in both reading and mathematics performance than their more food secure counterparts, as well as a greater increase in BMI over the three years.
The researchers attempted to provide a hypothesis as to why there is an association between food insufficiency and academic performance; one being that a lower household income would affect the quality of the food purchased, and could lead to poorer health decisions, such as ingestion of fast food or foods filled with sugar and little nutritional value. Another interesting hypothesis was that the stress from food insecurity could lead to an increase of cortisol levels, which has been related to depression, decreased cognitive functioning and the atrophy in synapses involved in learning and memory.
Their research found that food insufficient children and teenagers were more likely to miss school and to repeat a grade than food sufficient children. The study also showed the food insufficiency had both biological as well psychological effects on a child, some of which included micronutrient deficiencies, reduced food intake, and feelings of deprivation, stress, and worry.
Their research found a strong link between lower income families and food insufficient children. Coming from a lower income family, along with inhibiting the ability to eat healthfully, also affects the amount of health care a child can receive due to lack of affordable health care. This can lead to an inability to diagnose iron deficiency, as well as malnutrition, in children [ 8 ].
Consequences Brown, Executive Director of the Center on Hunger and Poverty, reported evidence from research articles that support Alaimo et al. These include, poorer health-which leads to an increase in illness, infection, and iron deficiency, poorer academic performance—which, as shown by Alaimo et al. It is important to note however that research as to the correlation between family income and obesity in children is still considered inconclusive [ 9 ]. As the literature discussed has shown, there is a relationship between academic performance and food insufficiency.
The effects that government programs have on lessening the academic gap created by improper nutrition is invaluable. The results showed that the USBP increased nutrient intake for the students, which also increased cognitive functioning and decreased absenteeism [ 10 ]. This study is just one example of the benefits of school breakfast programs in increasing academic performance among school-age children.
Background of School Food Programs The National School Lunch Program was created in by President Truman in order to both promote the health of American children as well as to push for the consumption of American- grown agricultural commodities. In order for schools to qualify for federal subsidies for free or reduced lunch, they must follow the guidelines provided by the National Nutrition Standards.
These regulations show that there is a strong understanding of the demonstrated correlation between nutrition and cognitive capabilities. The provision also cites increased academic performance as an incentive to utilize the program and integrate it fully into school structures [ 11 ]. Sugar-sweetened beverage consumption may be a marker of a poor overall diet and has been associated with other less healthful behaviors, such as getting fewer than eight hours of sleep per night and being sedentary.
A variety of other factors, such as parental education, parental IQ, and socioeconomic status, could contribute to the relationship as well. Though the research on the academic implications of sugar-sweetened beverage consumption is limited, it seems prudent to recommend keeping low the number of such beverages that children and adolescents consume. Even if the demonstrated relationships are due to another factor, from a health standpoint, the recommendation falls in line with the current dietary guidelines to limit added dietary sugars.
Fruit and Vegetable Intake Fruit and vegetable consumption is another area that has been explored for its impact on academic performance. In addition, students who chose vegetables and fruits left more than one-third of these items uneaten. Researchers in Nova Scotia surveyed 5, fifth-grade students and their parents. The researchers collected information on dietary intake and compared it with results of a literacy test.
Students with higher fruit and vegetable intake were less likely to fail the literary assessment than were students with lower intake. However, there are many potential explanations.
Correlation of nutritional status with academic achievement in adolescents
Among 5, fifth-grade students, those with poor overall diet quality were more likely to perform poorly on a literary assessment. In the first, the variable of poor diet was assessed based on how frequently the student consumed five foods: Among the 5, ninth- and 10th-grade students, there was a significant negative correlation between poor diet and good grades.
The ways in which diet quality influences learning have yet to be firmly identified, but several theories exist. Diet quality may influence energy balance and micronutrient intake, which are important factors in overall health and academics. Schools may see health promotion and nutrition education activities as being lower priorities than core curriculum subjects, particularly with a growing focus on standardized testing and the No Child Left Behind Act.
There are many unique avenues for RDs to become involved in promoting school wellness, including the following: This federally funded program provides schools with money to purchase fresh fruits and vegetables that are served as snacks during the school day. Research has shown increased fruit and vegetable intake among students in participating schools.
Better Academic Performance — Is Nutrition the Missing Link?
Issued in Junethese standards create new regulations for competitive foods sold in schools, including those in vending machines, and set limits for calories, sugar, fat, and food type.
Schools may need help interpreting and implementing these regulations, creating a perfect avenue for dietitians to approach them about consultant work. Consider focusing specifically on nutrition topics that influence both health and academic performance. These may be done in schools, through community organizations, or through a private practice. Many activity suggestions have been provided in the accompanying RD tip sheet available on our website. Also, the Kids Eat Right nutrition education presentations available through the Academy of Nutrition and Dietetics include a variety of topics and are available free of charge.
Mini grant opportunities to give school and community presentations frequently are available through Kids Eat Right. They could be published and then marketed to schools and organizations. Consider asking whether the grocery store will sponsor your time.
Teen educators can provide nutrition classes or tips to other students or just model healthful choices to influence habits.

Research shows adolescents with friends who eat breakfast, whole grains, and dairy are more likely to eat these foods themselves. If funding is an issue, look toward nontraditional routes for providing these services. For example, the school could create a donor project for nutrition education initiatives. Also, look into grant opportunities, work with private schools that typically have more flexibility in spending, or create after-school nutrition programs that charge a small fee for each student.
Moving Forward The push for school nutrition initiatives traditionally has focused on health outcomes. Other behaviors, such as adequate fruit and vegetable intake, better diet quality, and lower consumption of sugar-sweetened beverages, are supported by a growing body of evidence for their role in academic performance.
By focusing on the link between good nutrition and improved success in the classroom, dietitians can strengthen their argument for better school foodservice and wellness initiatives.
