Experts Warn Oklahoma School Lunches Lack Nutritional Value

“When you improve school food, it can help bolster academic outcomes in a statistically significant way,” says Nora LaTorre, chief executive officer of Eat Real.

The nutritional quality of Oklahoma school lunches is currently under scrutiny as experts warn that state-funded meals may be failing to provide the health and academic benefits taxpayers expect. While Oklahoma taxpayers fund school lunches statewide, recent legislative studies suggest many of these meals offer poor nutritional value, potentially contributing to lower academic achievement and long-term health issues for students.

The stakes extend far beyond the cafeteria line. Poor-quality meals can set children on a trajectory toward chronic health problems that persist into adulthood, eventually increasing the demand for taxpayer-subsidized healthcare. Dariush Mozaffarian, director of the Food is Medicine Institute at Tufts University, points to a growing national crisis where roughly one in four children is overweight or obese, and one in three teenagers faces pre-diabetes.

According to Mozaffarian, about one in four school meals today lacks sufficient nutritional quality. While upgrading these meals requires a higher upfront investment, he argues the cost is a preventative measure that saves money by reducing the future burden of disease-related healthcare costs.

The academic dividend of better nutrition

The link between what a student eats and how they perform in the classroom is more than anecdotal. For low-income students, the impact of improved nutrition is particularly pronounced. Justin Gallagher, an associate professor at the Department of Agricultural Economics at Montana State University, says these students gain much academically.

“If we just look at those students, their increases in test scores are about 50-percent higher,” Gallagher said.

Hungry or poorly nourished children often struggle with attention and focus, creating a barrier to learning that persists throughout the school day. By adjusting the types of food served, schools can see immediate physical changes in student diets. LaTorre noted that one school her organization worked with successfully removed 34 pounds of sugar per student per year simply by refining their food selections.

Santa Fe South High School, a public charter school in Oklahoma City, is currently in its second year of operating its Child Nutrition Program independently. The school has observed rising academic outcomes alongside improvements in lunch quality, though officials noted that nutrition is one of several contributing factors to these trends.

To understand the economic efficiency of nutrition, it helps to compare it to other common educational interventions. For instance, a 1999 study in Tennessee found that reducing class sizes can improve academic outcomes, but achieving that benefit requires cutting class sizes by roughly one-third. In 2025 dollars, that adjustment costs approximately $4,157 more per student.

Intervention Type	Estimated Cost Per Student	Primary Benefit
Improved Nutrition	$375	Notable test score improvements
Reduced Class Size	$4,157	Improved academic outcomes

The data suggests that improving the nutritional quality of school meals is a relatively low-cost lever for state lawmakers to pull. At an estimated cost of $375 per student, the investment in better food provides a measurable boost to student performance at a fraction of the price of structural classroom changes.

Critics of increased school meal spending often point to the immediate strain on state budgets and the necessity of fiscal restraint. The argument holds that adding costs to already burdened school systems is a luxury the state cannot afford. However, the current model of subsidizing low-quality meals presents a different fiscal dilemma: paying for food that simultaneously hinders learning and increases future medical liabilities.

If the goal of state-funded school lunches is to support the well-being and development of Oklahoma’s youth, the current nutritional standard may be working against that objective. Investing in the quality of the meal ensures that taxpayer dollars are actually buying the intended outcomes: healthy children and successful students.
