71% of US Baby Foods Are Ultra-Processed: EWG Reveals Additives, Sugar, and Salt Concerns

🔬 Key Revelations from the EWG and George Institute Study

Recent research has pulled back the curtain on a troubling reality in the baby food aisle of major U.S. grocery stores. A comprehensive analysis of 651 infant and toddler food products—targeted at children aged 6 months to 36 months—revealed that 71 percent qualify as ultra-processed foods under the NOVA classification system. This system, widely used in nutritional science, categorizes foods based on the extent and purpose of industrial processing, with ultra-processed foods (UPFs) distinguished by their reliance on additives, refined ingredients, and formulations designed for hyper-palatability rather than nutrition.

Conducted by experts at The George Institute for Global Health and highlighted by the Environmental Working Group (EWG), the study drew data from the FoodSwitch database, covering products from the top 10 U.S. grocery chains. Additives emerged as the dominant ingredient in 71 percent of these products, outnumbering even fruits and vegetables on labels. Over 105 unique additives were identified, including flavor enhancers in 36 percent of items, thickeners in 29 percent, emulsifiers in 19 percent, and colors in another 19 percent.

Ultra-processed baby foods packed nearly twice the total sugar—14.0 grams per 100 grams compared to 7.3 grams in minimally processed alternatives. Strikingly, all added sugars appeared exclusively in UPFs. The gap widened dramatically for snacks and finger foods, where UPFs contained 2.5 times more sugar (14.4 grams versus 5.6 grams per 100 grams). Sodium levels also skewed higher in UPFs at 70 milligrams per 100 grams, versus 41 milligrams in less processed options, raising early concerns for blood pressure and heart health.

• Nearly all snack-sized packages (94 percent) were ultra-processed.
• Full-size packages followed at 86 percent.
• Pouches, whose sales have surged nearly 900 percent since 2010, clocked in at 73 percent UPF.

These findings, published in the journal Nutrients in early 2026, underscore how convenience-driven formats like pouches often prioritize shelf stability and appeal over wholesome nutrition.Read the full peer-reviewed study here.

What Defines an Ultra-Processed Baby Food?

Ultra-processed foods represent the most industrialized end of the food spectrum. Unlike whole foods or simple preparations—like steamed vegetables or mashed fruits with minimal intervention—UPFs undergo multiple layers of factory processing. Manufacturers extract substances from foods (such as proteins or oils), use synthetic ingredients, and add cosmetic elements to enhance texture, taste, or appearance.

In baby foods, this translates to ingredients like xanthan gum or guar gum (thickeners to mimic smoothness), carrageenan (an emulsifier derived from seaweed but processed to stabilize), lecithin (emulsifier from soy or sunflower), and synthetic dyes or beet juice concentrates for color. Flavor enhancers, often labeled vaguely as 'natural flavors,' mask blandness or boost appeal. These aren't inherently toxic in isolation, but their combination in calorie-dense, nutrient-poor matrices raises red flags.

The NOVA system, endorsed by organizations like the World Health Organization for research purposes, flags UPFs by the presence of such industrial formulations. For infants, whose digestive systems and microbiomes are still maturing, this heavy processing can disrupt natural gut development. Emerging evidence suggests emulsifiers and thickeners may alter microbiota balance, potentially leading to inflammation—a precursor to allergies, obesity, or metabolic issues later in life.

📊 Health Implications for Infants and Toddlers

Babies' early dietary exposures lay the foundation for lifelong habits. A CDC report notes that ultra-processed foods now comprise 62 percent of U.S. children's daily calories, with baby food pouches contributing 50 percent of infant sugar intake. High-sugar introductions condition palates to crave sweetness, increasing obesity risk by up to 55 percent per 10 percent caloric increase from UPFs, per longitudinal studies.

Academic research from institutions like the National Institutes of Health links early UPF consumption to rapid weight gain, insulin resistance, and even behavioral challenges. For instance, synthetic dyes have been associated with hyperactivity in sensitive children, while emulsifiers like polysorbate 80 correlate with type 2 diabetes markers in animal models extrapolated to humans. A 2024 study in Pediatrics found infants on UPF-heavy diets 1.3 times more likely to experience rapid weight gain, straining developing organs.

Sodium excess, even modest, burdens immature kidneys, potentially programming higher blood pressure. Fiber-poor UPFs miss essential prebiotics for gut health, vital during the 'first 1,000 days' window when 90 percent of brain growth occurs. University-led cohorts, such as those at the University of North Carolina, emphasize how these patterns persist, fueling epidemics of childhood obesity (affecting 20 percent of U.S. kids) and metabolic dysfunction-associated steatotic liver disease.Explore NIH insights on UPF risks in infants.

The Regulatory Landscape: FDA Guidelines and Gaps

The U.S. Food and Drug Administration (FDA) sets voluntary guidelines for baby foods, recommending no added sugars or salts and emphasizing iron-fortified cereals post-6 months. However, enforcement is lax; no binding limits exist on sodium or sugars, and the 'Generally Recognized as Safe' (GRAS) loophole allows companies to self-certify nearly 99 percent of new additives without pre-market review.

Unlike the European Union, which bans certain dyes and caps sugars, U.S. parents rely on labels. The American Academy of Pediatrics has urged reforms since 2018, echoing calls post-2021 heavy metals scandal in pouches. States like California are acting: a 2025 law defines UPFs and phases them from schools, with similar bills pending.FDA's infant food safety overview.

This patchwork highlights opportunities for higher education: nutrition professors and researchers drive policy through studies, much like those seeking research positions in public health departments.

🍲 Practical Solutions: Choosing and Making Healthier Baby Foods

Empowerment starts at the store. Scan ingredient lists: prioritize products listing whole fruits, vegetables, or meats first, with fewer than five items total. Avoid vague 'natural flavors' or thickeners unless minimal. EWG's Food Scores database rates over 150,000 products, flagging UPFs.Check EWG Food Scores for baby foods.

Opt for jarred purees over pouches when possible; compare nutrition facts for sugar under 5 grams per serving. Homemade shines: steam and blend organic produce, adding breast milk or formula for familiarity. Recipes abound for iron-rich combos like spinach-lentil or sweet potato-quinoa.

• Read back-panel nutrition: aim low sugar/sodium, high fiber/protein.
• Choose glass jars for fewer plastics/BPA risks.
• Introduce textures gradually to build chewing skills.
• Batch-prep purees; freeze in ice cube trays for portions.

🎓 University Research Driving Change in Child Nutrition

Higher education institutions are at the forefront. The George Institute's work exemplifies collaborative efforts between universities like the University of North Carolina and global health orgs. Studies from NIH-funded labs link UPFs to neurodevelopment, with fMRI scans showing altered reward pathways in UPF-fed youth.

Professors in nutrition departments analyze microbiomes, while epidemiology teams track cohorts from infancy. This research informs WHO guidelines and inspires students pursuing faculty roles in dietetics. Rate professors leading these efforts on Rate My Professor to guide peers.
