Science Says Your Taco al Pastor Might Be Healthier Than Your Granola Bar

Science Says Your Taco al Pastor Might Be Healthier Than Your Granola Bar

The appetite for healthy eating continues to grow across Mexico even as a deep affection for traditional street food remains a defining part of the country’s identity, and the search for balance between these two impulses has produced a conversation that stretches across kitchens, classrooms, and nutrition labs. The rise of bars, cereals, snacks, and products wrapped in green labels with lofty promises has reshaped the way many people think about wellness, although the comfort of a taco al pastor or a plate of flautas still holds a place that feels constant and cultural.

A Study That Questions What We Call ‘Healthy’

The current fascination with foods that signal wellness has encouraged many consumers to reach for bars filled with grains or snacks that claim to support better habits, yet multiple international studies show that many of these products carry large amounts of sugar, sodium, and added fats that far exceed recommendations from organizations like the World Health Organization and the Food and Drug Administration of the United States. Against this backdrop, a scientific project by students at the Universidad de las Américas Puebla has gained attention because it challenges assumptions about Mexican street food, specifically the idea that tacos al pastor are an impossible indulgence for anyone seeking balance.

The study, titled Antojitos mexicanos una fuente energética, compared tacos al pastor and flautas de cochinita pibil. The students used specialized equipment to turn each sample into a uniform mixture and evaluated moisture, fat, protein, carbohydrates, and minerals. Their findings showed that tacos al pastor present 42.47 percent moisture, 11.92 percent fat, 20.77 percent protein, and 1.33 percent minerals. The flautas offered similar moisture and fat but contained higher carbohydrates and significantly lower protein.

The Wellness Market Faces an Uncomfortable Comparison Between Tacos al Pastor and Granola Bars

Global guidelines recommend that added sugars should stay under ten percent of total daily intake, or ideally five percent for additional benefits. Many granola bars and products marketed as clean or natural often exceed this threshold in a single serving because they contain between twelve and twenty grams of sugar, which places consumers near the recommended daily limit by the time they finish one bar.

According to El Heraldo de Mexico, research compiled by the Harvard T H Chan School of Public Health echoes this pattern and shows that foods advertised as healthy frequently rely on sweeteners and additives that reduce the nutritional value they claim to provide. When compared with this type of snack, a taco al pastor contains far less sugar and offers a distribution of protein, fat, and carbohydrates that aligns with traditional cooking methods that center maize, fresh pineapple, and seasoned meat. Although tacos do contain fat, their levels remain below what is found in doughnuts, fried potatoes, and several bars coated with a layer described as yogurt, which can reach fat content between twenty percent and thirty percent according to data gathered by researchers.

A New Kind of Awareness

The UDLAP study also noted that flautas de cochinita contain a substantial amount of carbohydrates, which can serve as an energy source for people with physically demanding routines, while still falling within acceptable fat values. The research team recommended a moderated approach that includes three tacos al pastor or four flautas depending on individual activity levels, frequency, and nutritional needs.

The project was led by students Karen Azucena Casillas, Fernanda Rodríguez, Itzel Ariadna Cacique, Ana Isabel López, and Enrique Jiménez under the guidance of Dr María Elena Sosa of the Food Engineering department. Their work provides evidence that moves the conversation past assumptions and into a space shaped by data, inviting people to rethink the narrative that places Mexican street food on one side of the health spectrum and modern packaged snacks on the other.

A Cultural Debate That Continues to Evolve

The larger impact of the research lies in its invitation to reconsider how tradition, wellness, and perception feed each other within a country that holds food at the center of daily life. The study does not diminish concerns around diet or health. Instead, it argues through evidence that the food long celebrated in Mexico is not the nutritional villain it has been labeled, and that many of the snacks elevated by marketing campaigns carry a burden of sugar and additives that often goes unnoticed.

This study also offers clarity for anyone searching for healthier choices while preserving the essence of street food that continues to define family gatherings, celebrations, and everyday life across the country. As for the taco: Their value extends far beyond nutritional tables because they exist within a collective story.
